erank ll for operating the driver through the intermediarv of pitnien 15. 16 being the (21111 shaft. whieh may be journ'aled in the frame h or other suitable part ot' the inaehine. as usual.

As the wire is advaneed through the anvil l) whieh is provided as usual with slot 17 for the reeepliion ot' the wire. it is pushed bark into its seat by a wire guide shown in detail in Fig. 5. and eonsisting of an arm 1h supported by pivot 19 and having an int-lined l'aee :0. arranged to be engaged by the tip of the wire as it is advaneed through the slot of the anvil, the wire guide being of the usual or any suitable eonstruetioin and held up to its work by spring 2t. or ol her suitable means. The wire being properly plaeed in the slot of the anvil. it is then engaged bv the bifureated wire former It). the end of the wire having been previousl severed. and both extremities of the severed portion are thus bent do\\'nwardl into a substantially U shape by the former. whieh straddles the anvil and is provided with groove in the inner fares of its branehes. as usual. for guiding the driver 11. whieh it enibraee and also engaging and holding the wire while being formed and driven. As the driver 11 desrends in the net of engaging and driving the staple. it first engages with the inrlined top fa e of the :uni] f as usual. and l'orees the same longitlulinall v out of it path and eventuallv engages and drives the staple tlo\\'ti \'attll while thibranehes ol' the staple are supported again t inward. ending in eoiiperation with the grooved branehe ot' the former. by the sup porter l'l. \vhieh 'is also engaged by the driver 11 and foreed baeluvardlv out of the way as the staple proeeeds downwardlv. the staple supporting end of the supporter 1; provided with a eurved tare '3 hr initiating in a point it. whieh is the last portion of the supporter to withdraw from the enibraee of the staple and the lower fat-eol' the supporter is struek on a suitable are 25.

so that as the supporter swings biu-lvwardly out of the way of the driver the point it will he brought into elose propinouitv to the surface into whirh the staple is being driven. its the driver rises from the driven staple the supporter 1:2 is returned to its former position by any suitable means sueh a a pring or other elastir' element 2o. while the anvil f is replaeed by the spring 27.

, which, together with the spring 26. serves to keep the end of the anvil and the curved surface 23 of the supporter 12 in close relation during the staple forming and driving operations. In this example of the inven tion the. anvil 9. shown in connection therewith. is of a familiar type, arranged in a horizontal position in a suitable socket 23, containing also the spring 27. the anvil being held against rotary action by a guide pin 29 in the usual way. An anvil of any other suitable form. however. may be employed.

The staple supporter 12 is connected by means of a pivot 30 to the lower end of a hanger 31, which serves to sustain the supporter in position. According to this invention, the hanger 31 is composed of a substantially straight rod or block provided at one end with a pair of lugs 32. by means of which the hanger is given support upon the former 10. which is provided with shoulders 33 for the purpose.-sucl1 shoulders being formed by recesses 34 in the sides of the former, which are extended in an upward direction to permit of a limited range of moveIm-nt of the former independently of the hanger 31, so that while the supporter 12 is resting contiguous to the surface into which the staple is being driven, the former may continue its downward movement in the act of forming the staple over the anvil. The bar 31, which rnay conveniently be rectangular, in cross section. is slidably housed in a cap 35, in the lower end of which is a recess 36 for accommodating the supporter 12, so that when thecap 35 is removed the lugs 32 may he simply disengaged from their recesses 34, and the supporter and its hanger 31 removed from their guide way in the cap 35, the same being held therein preferably without any other attachingmeans. The cap 35 may, of course, be held in place by screws 37, or other suitable devices. The hanger 31 also constitutes a housing for the supporter spring 26. To that end the hanger is provided with a socket 38, which may be conveniently formed by a drill, for receiving the spring, and also a plunger 39 which may be of cylindrical form, with its lower end protruding from the socket of the hanger and pro-. vided with suitable bearing point -10, shown in this example of the invention as hemispherical. engaging the supporter 12. which has a rounded face 41, upon which the bearing point 40 rests, and by which the supporter 12 is held up to its work, contiguous to the anvil 9 under the influence of the spring 26. The plunger 39 is held against accidental discharge from its socket 38 by a pin 42, engaging in a groove 43 in the plunger.

The former 10, containing the driver 11,

is housed within a guide box 44, suitably supported on the frame member 8, and provided with a passage or groove -15 for receiving and guiding the. former. Both the exterior sides of the former and the'guide walls of the groove 45 are preferably parallel. both transversely and longitudinally. so that the former together with the driver may be .removed transversely from the frontof the box 44 when the cap 35 1s removed.

The outer edge or face of the former is flush with the face of the box 44, as better Shown in Figs. 6-7. and the hanger 31 whose rear face is straight and fiat, fits against the outer face of the former 10.111111 is thereby held against undue inward movement, while it is held against outward movement as'well as lateral movement by the cap 35. which latter also overlaps the outer fa e of the former for preventing the latter from mov ing outwardly.

The wire guide 13 is also preferably mounted in a recess 46 in one side of the cap 35, containing also the wire guide spring 21, so arranged that the wire guide may recede into the recess 4tl entirely out of the way of the former and driver when they descend. Thus it will be seen that when thecap 35 is detached the former and driver may be readily removed from their guide box 44. the pitmen 15 being first disconnected. and the supporter 12 and its hanger 31 may be as readily removed from the cap 35 with the supporter spring 26 and plunger-39 intact. It will also be seen that by thus arranging the supporter spring within the hanger bar 31. or in position contiguous to and substantially parallel with the driver and former. certain protruding parts heretofore employed in front of the machine for supporting the spring are dispensed with.leaving'the front of the machine free and unob The combination with staple forming [f and driving members, of a block cooperating with and located adiacent thereto. a support pivoted to said block. and a spring actuated plunger mounted Within said block parallel to one of the vertical faces thereof and arranged to operate against 'said support to force the same into the path of movement of the staple forming and driving members at predetermined intervals.

3. The combination with staple formingand driving members, of a block cooperating with and located adjacent thereto, a support pivoted to said block, a spring-actuated plunger mounted within said blockand arranged to operate against said support and force the same into the path of movement of the staple forming and driving members at predetermined intervals, and means for limiting the movement of said plunger.

at. The combination with a frame, of a staple former and driver mounted therein, a cap secured to said frame provided with a projection having a longitudinal passage therein, said passage having a transverse enlargement at the lower terminal thereof, a hanger mounted for reciprocation in said passage, means for reciprocating said hanger from the former aforesaid, a staple sup porter pivotally connected to the lower end of said hanger and mounted within the enlargement aforesaid and contained wholly within the cap, and means mounted within said hanger for forcing said supporter into the path of the staple former and the driver at predetermined intervals.

5. The combination with a staple former, elongated recesses formed on each side of said former, a block located adjacent to said former, lugs carried by the upper terminal of said block adapted to be received in said recesses whereby the former may have a movement independently of said block, a staple support pivoted at the lower end of said block, and automatic means contained entirely within said block whereby said staple support is caused to swing into the by said former, and having a passage in the lower terminal thereof, a spring-pressed plunger mounted in said passage, and a staple supporter mounted on the lower terminal of said hanger, said staple supporter being segmental in formation and extending into the enlargement aforesaid, the portion thereof in said enlargen'ient being ope 'ated upon by the spring-pressed plunger.

7. The combination with a block, of a quadrental support pivoted at the lower terminal thereof, said support having the convergent faces thereof curved inwardly, a plunger mounted in said block, a spring mounted in said block, and a plunger acted upon by said spring and bearing against one of the curved edges of said support and adapted to force the latter automatically in a given direction at predetermined intervals.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 3rd day of August, A. D. 1911.
