` on, which form a part of this specification.

This invention relates to lasting and tacking machines; and it consists `of certain improvements the objects of which are not4 only to hold an upper for the purpose of lasting` it, but also to manufacture headed tacks from a peculiarstrip of metal having a ridge on both `sidesof the strip, and, further, to drive such 2o headed nails or tacks into the upper, these three operationstaking place in the same machine.

In order that my invention may be clearly i understood, I will now'proceed to describe it conj ointly with drawings hereunto annexed.

Figure 1 is a plan of the machine; Fig. 2, a front elevation of the same in sectionthrough the line A A of Fig. 1;" Fig. 3, a sectional elevation through the line D D of Fig. 2, Fig. 4, a lateral elevation i n section-through the line C Cof Fig. 1. Fig. 5 is oneform of a strip of zinc from which the tacks are made, and showing the lines where they are severed from the strip by the action of the machine. This iigure 5 is on a larger scale than the remainder. Fig'. 6 is a longitudinal elevation, in section, through the line fB B of Fig; 1, with the column supporting the machine. 'Fig. 7 shows the clutch in section, and Fig. 8 is acrosssection of the same throughline E E of Fig. 7.

Iwill now proceed to describe the construction, arrangement, and operation of the machine.

1 is the driving-shaft, and 2 is the drivingpulley. In order to manufacture the tacks separately, the operator must be able to limit exactly the runof `the machine. For this purpose I make use of the clutch shown in Figs.

7 and 8. YIn the hub of the driving-pulley 2 is a cavity, 3,' Figs. 7 and 8, which resembles a gear having internal teeth. The pulley. 2 causes the'shaft 1 to rotate as soon as the bellcrank lever 4, Figs. 7 andP 8, bears with its side lug, 5,1against one/of the teeth'7 bymeans Tof the bell-crank lever 4, which butts against a bolt, 10. The lug of the upper lever-arm is raised and is released from one of the teeth 7 and the pulley runs loose on the shaft-#that is to sa ,the machine will not'rotate;y but if the machine has to work, the operator presses on the pedal 11 in order to push the springbolt`10 to the left by means of the rod 12, double lever 13, and stud 14. The lower leverarm is then liberated, the spring 6 pushes the upper arm, with its lug 5, against one of the teeth 7, and the shaft 1 follows the same motion. After a complete revolution, the bolt 10 reassumes its original position by means of the spring 15, the bell-crank lever 4 butts with its lower arm against the said bolt, andthe lug 5 is liberated from the tooth 7 and the machine stops. In order to cause the shaft l to turn more than once, the pedal 11 is depressed accordingly. i

Upon the shaft l is keyed a gear, 16, which meshes into the teeth of a gear, 17, the dialneter of which is twice that of the gear 16.

Upon the gear 17 is a crank, 18, which acts upon a slide, 20, by means ofa rod, 19. The arm 2l of this slide butts with its small roller 22 first against the stop 23 and then against the stop 24 'of the part 25, Fig. 1,- and causes the latter to oscillate. Together with the part '25 also oscillates the projection 26, Fig. l, which engages in the groove 27 of a sleeve, 28, `thus imparting ato-and-fro motion to the said sleeve. The sleeve 28 is loose on the `hollow cylinder 31, Figs. 1 and2, whereas the collars 29 and 30 are keyed on the saidjcylinder or tube. The `cylinder may turn in bearings 33 34, which are capable of being raised and lowwhich the tacks are cut off, and the cross-section of which corresponds to an I or 1 and the tacks cut from the strip having always a head at one end, while being headless and comparatively sharp at the other end, as will be readily understood by reference to Fig. 5.

' Upon the said strip bear the sharp edges ofthe clicks 35 36, Figs. 1 and 2, which allow the strip 32 to move forward toward the left, Fig.y 2, but prevent it from retrograding. Upon the motion of the sleeve 28 toward the right,

to the extent of the breadth of one tack toward oscillations of the part 25.

the shears 39 and knife 38 in consequence of the to-and-fro mot-ion of the sleeve 28 by the Jl/'hen the strip 32 has been advanced so far that its right end lies in between the clicks 3.5 and 36 of the collars 29 and 30, it is no longer seized by the click 35 and fed forward in the machine. To remedy this I have adapted an extra click, 37, upon the collar 30, which acts to replace the click 36 when a fresh strip, 32, is introduced into the hollow cylinder 3l. The said click 37 now acts in place of the click 36, and while the fresh strip is brought forward by the click, it pushes or drives the remainderof the former strip toward the shears until the said remainder is used entirely. By this arrangement there is no waste of the material forming the tacks.

In order to sever the tacks from the strip 32 through the lines shown at Fig. 5, it is necessary that the longitudinal axis of the strip be oblique to that of the shears, (see Fig. 1,) and that the strip lie or rest upon the bearing 40, Figs. 1 and 2, once on one side and once on the other side-that is to say, the strip must be turned over to an angle of one hundred and eighty degrees. This motion is effected by the pinion 41, Figs. 1 and 2, driven by the rack 42, which receives its motion from the lever 43, fastened to a stud, 44, of the slide 20, but as at each. revolution of the gear 16 the gear 17 only makes half a revolution, and as the slide 20 thereby executes either a backward or a forward motion, the change of position of the lever 43 will correspond to that shown in full lines and in dotted lines, Fig. 1, at every com- Y time the pivoting-piece 25 is caused to oscillate, its roller 22 coming in Contact with the stops 23 and 24 at each forward and each backward motion under the action of a small spring, 45, Fig. 1. To the sleeve 28 is thus imparted a to-and-fro motion, and the strip 32 is moved forward to the extent of the width of one tack. Therefore it will be seen that one tack is made ateach revolution of the shaft 1. While the tack is being severed, the strip 32 lies or rests upon the bearing 40, Fig. 2; but before it is turned over it must be slightly raised.

The

and 4, which is actuated by a pin, 46, fastened to the slide 20. The pin 46 depresses the lever 45', except when it assumes the extreme positions. It then engages one of the slots 47 or 48, Fig. 4 and allows the said lever 45 to rise, whereupon the bearings 33 and 34 are lowered. The strip 32. then bears upon the bearing 40, and it can then be cut by the shears. The knife 38, together with the slide 39, Vto which it is attached, receives a vertical toand-fro motion by means of a lever, 67, Fig. 6, which receives a to-and-fro motion by means of an eccentric, 68.- The severed tack falls upon the part 49, Fig. 2, which is between the bearing 40 and the slide 39, and thus lies in a groove or channel, from where it is driven into the upper by means of a needle, 50, fastened to aslide-bar, 51, Figs. 1, 2, and 6, immediately after it has been severed from the said strip 32. The slide-bar 51 is operated by a roller, 52, to which motion is imparted by a cam, 53, on the shaft 1, a spring, 54, acting for driving the said slide to the left. Ihe bearing 56 for the slide-bar 51 is'provided with a flexible or IDO raises the lever-arm 64, Fig. 1, wherebyI the,y

cam 65, fastened at the end of the lever 64, comes under the horizontal arm of the 'jaw 59, and causes the latterto be brought againstY the stationary jaw 58, in order to hold tight-r ly the upper. By depressing the pedalr 60 the spring 66 presses upon the horizontal arm of the movable jaw 59 and causes the jaw to rise, so that the upper can then be taken out.

Instead of the zinc strip 32 assuming a longitudinal head on each edge, its edges may simply be turned over, so as to form an 1 and I may here remark that by means of the arrangement which causes the said strip to be turned over, first on one side and then on the other, tacks Imay be severed therefrom without any waste whatever.

The above-described arrangement of pinchers for holding the upper, as above stated, may be applied to any machine the purpose of which is to drive nails into boots and shoes orinto uppers, whether the said tacks are introduced ready-made into the said machine or severed from a specially-prepared wire or strip.

I claim as my invention- 1. In lasting and tacking machines for boots and shoes, the device for causing the strip 32 to be turned over, composed of the hollow cylinder 3l, pinion 41, rack 42, lever 43, slidebar 20, 4and connecting-rod 19, as shown and described.
