BUTTON-SETTING INSTRUMENT.

SPECIFICATION forming part of Letters Patent No. 353,818, dated December '7, 1886,

Application filed February 9, 1886.

To all whom it may concern:

Be it known that I. FRANCIS H. Rrcnnnns, a citizen of theUnited States, residing at Springfield, in the county of Hampden. State of Massachusetts. have invented certain new and useful Improvements in Button-Setting Instruments, of which the followingisa specification.

This invention relates to improvements in hand-instruments for attaching butto us to fab- 1o ric or leather by means of malleablepointed metallic fasteners, the object being to provide an instrument of that class in which the fasteners shall be automatically fedto the driverchannel from a magazine within the instru- Inent.

To this end the invention consists in the combinations hereinafter described and claimed.

In the drawings accompanying and forming a part of this specification, Figure l is a top View of a button-setting instrument embodying my improvements. Fig. 2 is a side elevation of the same. Fig. 3 is a top view of the lower left-hand part of the instrument, showing the slide, slide-case, and the front end of the magazine. Fig. 4. is a longitudinal vertical section through theinstrumcnt, showing the parts in position ready for operation. Fig. 5 is a front view of the instrument as seen from the left hand in Figs. 1, 2, and 3. Fig. 6 is a similar view showing some of the parts situated at the close of the setting operation. Fig. 7 is a bottom view, showing from the under side the same parts as shown in Fig. 3. Fig. 8 is a cross-section in line a a of the 5 handle containing the fastener magazine. Figs. 9, 10, 11, and 12 are sectional views showing four successive stages of the opera tion of feeding a fastener from the magazine into the driver-channel. Figs. 13 and 14. are similar views showing two stages of the fastener-setting operation. Fig. 15 is a side elevation, partially in section, showing the magazine-cover drawn back preparatory to replenishing the supply of fasteners. Fig. 16 is a section of the magazine with the cover removed. Fig. 17 is a perspective view of the magazine-follower. Fig. 18 is a similar view of the slide-case, showing the interior thereof. Fig. 19 is a perspective view of the front part of the slide. Fig. 20 is a similar view of the Serial No. 191,362. (No model.)

back part of the-slide, showing the front surface thereof. Fig. 2l is a similar View of the driver, showing the rear surfaces thereof. Figs. 22 and 23 are respectively perspective views of the fastener-feeding pawl and of the transfer-spring.

Similar characters designate like parts in all the figures.

The frame-work of the instrument (designated by A) comprises a handle, H, forming the principal part of the fastener-magazine, and any suitable projecting armas, for instance, Bcarrying the setting-die and its operating devices. For convenience in constructing and assembling the parts, said arm is preferably divided, substantially as shown, to form a space for the reception of the parts carried by the arm. Said parts consist of the sliding setting-die D, a handle, O, pivoted at 2, and some device so connecting said handle and die that a downward movement of the one will produce a like movement of the other. For this purpose I have devised an arrangement of gearing, as follows: Rack-teeth 3 are formed on the back side of the die, which teeth mesh with similarly-shaped teeth 4. on one side of the intermediate gear, G, which is pivoted at 5 to the arm B. The opposite side of gear G has teeth 6, arranged spirally to its axis, and meshing with the teeth 7 of a correspond- 8o ing spiral or eccentric segment, 8, formed on handle 0. \Vith this arrangement of gearing, the eccentricity thereof being in the right direction, as shown, a regular and uniform movement of the handle imparts a movement of decreasing velocity to the die, thereby gaining in power near the close of the setting operation, and thus better utilizing the stroke of handle 0 than would otherwise be the case. A spring, 9, is arranged to raise the handle 0, 0 and through this the setting-die.

In another application, No. 181,383, filed October 30, 1885, for an improvement in pliers,

I have described and claimed a combination of devices adapted to be substituted for the aforesaid gearing for similarly operating the setting-die in my present instrument. In this case, however, the setting-die may be carried on the swinging arm, (therein designated by B.)

The magazine is an inverted-T-shaped 10o passes, as at 21, Fig. 15.

groove formed partly in the handle H and partly in its sliding cover R. The shape of the groove may, however, be modified to suit the fasteners, for the setting of which the instrument may be in any particular case more especially designed. In the present instance said instrument is constructed for setting the fastener thatis described and claimed in United States Patent No. 314,684, granted to' Eleazer Kempshall, March 31, 1885, one of which fasteners (designated byF) is shown in side view in Fig. 8, and a row of them (designated by the same character) in Figs. 4, 9, 10, 11, 12, 13, 14, and 15. The shape of the groove is shown partlyin solid and partly in dotted lines at V, Fig. 16. On the upper side it opens into a parallel cylindrical hole or channel inclosing the magazine-spring 11 and the follower 12, which serves to push forward the fasteners F in groove V. Said follower has a short extension, 13, which projects down through the groove V into a groove, 15, formed in the upper side of the cover B. This groove 15 does not extend quite to the forward end of said cover, but terminates at ashort stop, 16, Figs. 13 to 15, by which means the follower is drawn back with the cover, when this is slid off, as in Fig. 15,'to open the magazine. This operation of course compresses spring 11 against the plug 17, which stops up the rear end of channel 10. It will be noticed that cover R has in this instance a hook, 18, provided as a convenient means for operating said cover. It is also my intention to use a spring-catch (not shown) for temporarily retaining said cover in its open position.

It will be noticed that the method of fitting cover R to frame A is the common one of forming tongues on one part, which fit in grooves formed in the other, as fully shown in Fig. 8. This construction is not essential, but is adopted.

merely because it is convenient to make.

At its front end the frame A has a front plate, 20, extending below the magazine, and through which the T-shaped magazinegroove To this front plate the sides 22 23 of the slide-case L are respectively secured by rivets (not shown) or by screws. The slide (designated by N) consists in a front part, 24, and a rear part, 25. These two parts, secured together by rivet 26, comprise but a single operative slide, which might just as well be constructed integrally were its shape such that it could in practice he so manufactured. The driver 30 stands in the space between the two parts of slide N, being held from vertical movement by some suitable connection with slide-case L. This connection is preferably made as follows: On the inner side of

walls

22 and 23 are formed the grooves 27 27, into which are fitted the corresponding lugs, 28 28, Fig. 21, formed on the edges of the driver. By means of this construction the driver is firmly held, yet allowed to adjust itself laterally to the adjacent parts-an important consideration. The lower end of the driver 31, Fig. 21, serves as a stop against the short projection 32 on slide part 24, to limit the upward stroke of said driver to its posithe fasteners F are then forced by the follower against the thin part or blade 36, and immediately above ledge 37 Fig. 21, of said driver,"

as shown in Figs. 4, 9, 12, and 15. Said ledge has a width closely approximating the thickness of one fastener, as 38, Fig. 15, and theslide part 25 has a thickness similarly corresponding to one or morein the present instance to two-of them. The space between the upper end of slide part 24 and the raised surface 42 and slide part25 is the driver-channel 44, through which space the fastener is, driven upagainst thesetting-die;

For the purpose of transferring fasteners from above ledge 37 to above the driver-point 49, slide part 25 is provided with a fastenerfeeding pawl, 41, and with a transfer-spring, 45, both of which are readily made of wire, as

shown in Figs. 22 and 23. The pawl is conspring in another recess, 47, both formed in the slide part 25. g The operation of these parts is fully illustrated in Figs.9 to 12. SlideNand the accompanying part are shown at rest in their normal positions in Fig. 9, fastener 38 resting against thedriver-blade 36, while the fasteners 39 stand in opening 35. In Fig. 10 the slide is moved down to its lowest posit-ion, carrying fasteners 39 down between the lower end of the driver and front plate, 20, and the point of pawl 41 into notch 40, below fastener 38, which in the meantime has remained .on ledge 37, and now rests there under spring 45. In Fig. 11 the slide has moved up about twothirds of the distance toward its first position. The pawl 41 has pushed up fastener 38, whose pointhas been thrown forward by spring 45 into driverchannel 44. On the completion of understood from the drawings and preceding description. In using the instrument the fabric or other material,50, is properly placed over the slide N and the setting-die brought down on it, as in Fig. 13. A button, 51, is then put with its shank in the cavity 52. (See Fig. 4.)
