Handie - Japan.Handie is an affordable prosthetic hand with inbuilt myoelectric sensors which can read brain signals. Costs have been reduced by using a smartphone to compute the electrical impulses on the skin’s surface. All components of the hand are easily modified and reproduced using a 3D printer. The hand relies on one motor that changes trajectory depending on the shape of an object.

Dedicated readers might remember the Handiii (previously known as Handie), as Exii has been working it on since 2013. This team of graduates from Sony's manufacturing industry – consisting of Gentu Kondo, Hiroshi Yamaura, Tetsuya Konishi and by Akira Morikawa – are now finally nearing production. Over the past two years they have developed a high quality bionic prosthetic that could cost as little as $300 and have won the first prize in Gugen hardware contest in Tokyo with their concept, as well as the second price in the 2013 James Dyson Award.

SPEGIFlLCATIQN forming part of Letters Patent No. 680,243, dated August 13, 1901. Application filed Flay 4, 1901. Bcrial lie. 58,697- (No modem 1 To all whom it may concern: Be it known that I, GAETANO GIODA, a citizen of the Kingdom of Italy, residing in New York, borough of Manhattan and State of New York, have invented certain new and useful Improvements in Repeating Pistols, of which the following is a specification. This invention relates to an improved pistol of the class which can be readily carried in the pocket and which pistols are provided with magazines for receiving a supply of cartridges; and the objects of the invention are to provide a pistol which permits the folding of the barrel alongside of the handle, which is provided with means for quickly looking the barrel in position at right angles to the handle, and which is so constructed that the supply of cartridges in the magazine oi the handle can be rapidly fired in succession. My invention consists of certain other features of construction and combinations of parts, to be hereinafter described and then particularly claimed. In the accompanying drawings, Figure l is a side elevation of my improved repeating pistol, the barrel of the same being shown folded against the handle for convenient insertion and carrying in the pocket. Fig.2 is a plan of the repeating pistol, partly in section at one side, also shown folded. Fig. 3 is a sideelevation of the same, showing the barrel in firing position. Fig. l is a side elevat-ion, parts of the handle being in section, so as to show the magazine and some of the interior parts. Fig. 5 is a vertical longitudinal section through" the magazine and the barrel, the barrel being in position for firing. Fig. (5 is a side elevation, the barrel being in firing position, looking toward the opposite side of the repeating pistol and showing details of the locking device; and Fig. 7 is a vertical longitudinal section of the breech and lock, showing the same on a larger scale. s ,i of cartridges and which is constructed in any Similar letters of reference indicate corre sponding parts. Referring to the drawings, A represents the handle of my improved repeating pistol, and which is provided with side plates A of suit able material. Arranged longitudinally with in the handle is a magazine M for the supply suitable manner. The upper end of the magazinc is provided with a charging-mouth in, opening through the breech of the pistol, and with a springactuated follvver m, that lifts 5 5 the cartridges and places them in line with the chamber or bore of the barrel 3. Said barrel is fulcrumed at a to the upper end of the handle A and is adapted to be folded into a longitudinal recess a, formed in the handle parallel with and in front of the magazine, as shown in Fig. 1, or the barrel may be swung on its pivot a into position at right angles to the handle, as shown in Fig. 3, in which position it may be looked, as hereinafter described. In Figs. 2 and 6 it will be seen that under one of the'side or face plates A of the handie there is arranged a locking-pin b, that is carried by the free end of a fiat spring b, suitably attached at its other end to the handle, said locking-pin entering a socket or hole b formed at one side of the barrel B and serving to hold the barrel folded up against the handle. In this position the pistol may be readily carried in the pocket. When it is desired to place the barrel B in position for firing, the locking-pin b is released from the sochet'b in the barrel by means of a lever I)", suitably pivoted to the handle at b and which engages at one end with the free end of the locking-pin spring I), while the other end of said lever 11 is provided with a puslrpin D which passes through a hole 0 in the appropriate side plate a of the handle to the outside. By depressing the protruding end of the push-pin I) of the lover I) the locklug-pin b is withdrawn from the socket b and the barrel released, so that it can be swung into firing position at right angles to the han-- die, as shown in Fig. 3. Fixed in the barrelreceiving recess a of the handle is an actuating-spring B, which is bent outwardly and which tends to throw the barrel into such position as that the barrel may be readily taken hold of and moved into firing position. in the lower end of the handle A is are ranged a recess a, in which is guided the stem or shank t of a trigger or finger-piece T, which trigger is attached to the projecting outer end of said shank and which is prothe inner end of the shank and a stationary plug :5 inserted in the lower-end of the ham rile at right'angles to its axis. Through the trigger-spring 6' passes a guide-pin 25 which is fixed to'the plug t and enters and is guided in a suitable longitudinal hole in the shank t, as shown in dotted linesin Fig.4, when the trigger is pushed inwardly. The shank t :-is recessed at one side atria-the walls of said recess t engaging, the lower end 01; a lever T,"-'forming a part'of the lOCk'Of the pistol and fulcrumed to the handle at the upper end of said lever being bent rearwardly and upwardly and its upwardly-extending portion being inclined rearwardly, so as to engage a suitable piece of a sliding breechbl'ock,,as shown in Figs. 4 and hand which lifnlzih eing attached at 0 to a lug or projee-- G indicates a-recess'formed i-na bar or link (tithe rear-wallet which recess is inclined so as-to permitthe said; inclined end of the l ve-rT/ t'o enrer the recess, and said bar or v ti'on G9, which projects downwardly from the rear end of thebreech-bloek and isguided in gitudid'al rib G which a an annular shoulder a longitudinalslot bflformed inthe thickened p'ortionformi'ng the frameD of the barrel B, so as to properly guide the breechblock without permitting its rotation. The said bar or link 0*, connected with the brcecl block, is provided at its outer side with alonis guided in alongitridinal gu'ideway 'w,formedat one side of the frame, D, so as to properly guide thersaid bar or lint: under theactuation'oi? the le'rerT. breech-block C is provided with axial spring-actuated firing-pinE, said pinbeing guided in a hole e in the rear end of thesliding breech-block and in a disk c, fixed rigidly in the front end-0f the same, as shown clearly in Fig. 7. w r e 'indicates the spring of the firing-pin, and. or flange on the for.- ward end of the pin. r The frame D-ie provided with an open portion above and below the breechhloclnso as to provide the necessary space for the removal of the cartridges and the space for feeding the cartridges from the. magazine ihto line with the firing-pin and the chamber v aforesaid of the barrel. When the breech-block O is in its retracted position in the frame D, the shoulder e on the firingpin is in engagement with one arm f of an apthe frame D'and is proximately U or horseshoe shaped cockingl'ever-F, that is fulcr'umed at one corneror bend thereof to a lug F, which isadapted entlydescribed. extends into the path of a lugf, that projects from the under side of the rear end of the breech-block O and serves upon thejforwardmotion of the sliding breechbleck to engage the said arm f, and to there- .by oscillate-the cockingdever F on its-pivot, and produces at the proper time the-release locking device Z. d' in the lower part of actuated by the spring I to operate thescocking' lever F, soasto cook the firing-pin, asjpresseems I l the shoulder e of the firing-pin from the longer arm f of the said lever. breech-block C is being moved forward under the actuation of the trigger, the above lugf strikes the cocking-lever F, and armf of said lever by its engagement with the shoulder c on the firing-pin compresses the spring 6 in the breech-block, so as to store power in the said spring and to impart forcible action to the firing-pin immediately it is released from the detaining-arm f. The sliding breech-block is provided with a nicked or notched forwardl projecting lug or lip h, which serves. as "the extractor and engagesthe rim of the cartridge-shell, so as to withdraw the same from the chamber of the barrel, so that it may be thrown and ejected out of the barrel by the action of the extractor h, drawing the cartridge-shell into contact with a pair of inwardly-bent projections or ahutments i, sov as to tilt the shell, thereby ejecting the shell and throwing it from the barrel. The barrel islocked in firing position by means of a locking-pin Z, (see Fig. 6,) which is carried at the free end of the fiat spring Z and engages a suitable hole .in the frame of the barrel. My improved repeating pistol is carried in the pocket in the position shown in Figs. 1 and 2, with the barrel folded up into the recess a at the front of the handle; When it isdesired to use the pistol, the locking-pin Z1 is released and. the barrel swung on its i'ulcrum a into position at right angles to the handle and l'ockedin this position by the with the palm of the hand resting against the back of the handle, while the fingers are engaged over the trigger T. The backward pressure on the trigger oscillates the main lever T, and thereby produces the forward motion of the'breech-block and causes the latter to push the uppermost cartridge into the rear end of the chamber of the barrel. As soon as the cartridges are pushed in position the breech-block closesthe breech, and simultaneously the lug f on the breech-bloclc engages the arm f of the cocking-lever and releases the arm f from the shoulder a whereupoh-the firing-pin strikes the cartridge and the 'same is'exploded. On the return of the trigger to normal position the fulcrumed main lever T is returned to its former position and the sliding breech-block moved back in the frame, while the shoulder a snaps past the tip end of the arm f of the ooelringdever and again engages the same, as shown in Fig. 7. Simultaneously with these movements the extractor it engages the rim of the shell, brings it into contact with the abutments 1S, and the latter acting in conjunction with the. extraotor tilts the shell and ejects the same. Upon the ejection of the shell the next following cartridge is pushed up in line with the chamber of the barrel. The firing of the cartridge takes place at the end of the forward motion of the breech-block, so that the cartridges The handle is then grasped, While the may be fired in rapid succession by the rapid repeated pressing hack of the trigger. The - magazine can be charged with a suitable number of cartridges-say six to ten-'-which may be tired oit in rapid succession until the I magazine is emptied. The magazine is then refilled with cartridges by dropping them through the mouth thereof. Having thus described my invention, I claim as new and desire to secure by Letters Patent-- 1.
