lVlACi-hllixlE FOR SETTING BUTTONS.

SPECIFICATION forming part of Letters Patent No. 309,625, dated December 23, 1881i.

(No model.)

To @ZZ whom t may colzccrlm Be it known that I, ELEAZER Knnrsiemiyr., a citizen ci' the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented anew and uscful Machine for Fastening Buttons to Shoes and other Articles, of which the following description and claims constitute the specification, and which isillustrated by the accompanying ve sheets of drawings.

This machine operates with a treadle, and is used to attach buttons to shoes or other articles with the bntton-fastener and by the method described in my application for Letters Patent for an improvement in buttoniasteners, iiled December 17, 1883.

In the drawings, Figure l is a plan view of that part of the machine above the stand. Fig. 2 is a perpendicular crosssection on the line 7 7 of Fig. l. Fig. 8 is a front view of the machine with the disk V and that part of the stand forward ci the disk removed. Fig. i is a perpendicular cross-section on the line S S of Fig. l.. Fig. 5 is an edge view of the disk V. Fig. G is a view of the inner side of the disk V, with a portion ol' the ring broken away.

A is the stand. B is the treadle. C is the spring, lifting the treadle after it is depressed by the foot of the operative. D is a jointed connecting-rod, and E is a straight connecting-rod, both worked by the treadlc. The connecting-rod E is attached to the treadle at F, so as to be out ofthe way of the foot of the operative, and about twice as i'ar from the pivot of the treadle as is the corresponding attachment of the connecting-rod I).

G is a lever of the third order, the powerpoint of which is pivoted to the jointed conl necting-rod D, and the fulcrum of which is pivoted to brackets extending upward from the casting I-I, and the resistance-point of which is the die that bends the prong of the buttoniastener, as hereinafter explained. The downward stroke of the die is limited by the end ofthe screw I, passing through the lever G.

.T and K are springs, the former of which is placed above the latter, and both fastened at their ,fixed ends to the upper surface ot' the N is a carriage reciprocating upon the right- 6o hand side of the bracket M, being attached thereto by the screw O, passing through the slot of the carriage, and being operated by its indicated pivotal attachment to the connecting-rod E. I is a pawl pivotcd to the inner side 0f the carriage, and worked by the spring Q, and limited in its outward movement by the post R. S is a carriage reciprocating in the space between the forks of the bracket M. This carriage has a pla-in horizontal central round hole, and a plain perpendicular round hole of a much smaller diameter extending downward from the lower part of the periphery of the horizontal hole through the lower wall of the carriage. The carriage is supported and reciproeated by the post T, the upper end oi whichproj ects through the perpendicular hole and nearly half-way across the diameter of the horizontal hole oi the carriage S. The car- So riage :rests upon an annular shoulder on the post T, andY that post rests upon the spiral spring l, which is inclosed in the lower part of the round perpendicular recess in which the post T reciproeates.

V is a disk having a central round hole and a series of radial recesses on its inner side. In the bottom or" each ci' these recesses a fiat bifurcated spring, IV, is pivoted. Over the free ends of those springs the ring X is screwed upon the border of the disk V.

Y is a lock-bolt having a milled disk for manipulation, and two annular shoulders ad jacent to that disk. The bolt proper is round and slightly smaller in diameter than the hole 9 5 in the disk V and smaller than the horizontal hole in the carriage S. The inner end ofthe bolt Y has a recess forthe reception oi the upper end of the post T. That recess starts at .the end of the bolt and extends lengthwise along its periphery a little wider than the diameter.

thest side wall of the longitudinal part of the recess. That side of this lateral part of the recess which is nearest the smaller end of the bolt is slightly concave, with the axis of the concavity in the direction of the diameter of the bolt.

Z is a spring cut from iiat metal and having a central hole,through which it rests upon the larger of the two annular shoulders of the bolt Y, and also having extended corners bent toward the end of that bolt, so as to occupy a plane in advance of the plane of the smaller of the two annular shoulders on the bolt.

A is the anvil, upon the upper concave edge of which the base of the buttonfastener B is supported against the downward movement of the die at the resistance-point of the lever G. The right-hand edge of the anvil A is shown in Fig. 2. ltisfastened by ascrew to the left-hand' end of the casting H, and has its upward projection extending parallel with but out of contact with that end of the casting.

The mode of operation of this machine is as follows: The bolt Y is removed by giving a quarter-turn to the left and then withdrawing it. The disk V is then removed with the left hand of the operative, who with the right hand places a single button-fastener between each of the springs WV and the ring X in the position shown in Fig. 6. Then the operative replaces the disk V, and the bolt Y locking the latter by giving it a quarter-turn to the right, after it has been forced inwardly,so that the longitudinal part of its recess incloses the top of the post T. Vhen the disk V is properly replaced, the upper projection of the anvil A has its front side in contact with the front side of one of the springs NV, which springs are sunk into their recesses so far that their presented surfaces are as much below the general inner surface of the disk V as'the upper projection of the anvil is thick. The disk V being thus properly replaced, the operative with the left hand holds the article to which the button is to be fastened between the die in the lever G and the upper part of the periphery of the disk V, and'between the springs J f and K, and with the right hand holds the button above the upper surface of the article to which it is to be fastened and withl its eye Liiatwise under the die in the 1ever G. The end of the lever G is concaved,

as shown in Fig. 1, andthe relation of the concavity to the position of the die is such that when the base of the button is held against the concavity the eye of the button will bein the proper position for fastening. Then the operative with the foot depresses the treadle B. The connecting-rod D is thus forced to pull down the lever G,and the die end of that lever clasps the eye of the button between it andthe upper periphery of the disk V, and then forces that disk bodily downward until the lower end of the screwv I comes in contact with the head of the screw which holds the springs J and K. During this downward movement of the disk V the particular button-fastener which is just above the concave upper edge of the anvil A is prevented by the anvil from going downward with the disk. The downward motion of the lever G therefore forces the article to which the button is to be fastened down upon the point of the button-fastener, and also forces the eye of the button over that point after the point has been forced to puncture the article to which the button is to be attached. Thereupon the point of the button-fastener comes in contact with the concave die on the lower surface of the resistance-point of the lever G, and by that die is bent over toward the longer end of the base of the button -fastener, and then forced to penetrate into the upper surface of the article to which the button is being attached substantially as shown in the drawings of my aforesaid application for Letters Patent led December 17, 1883. Then the operative releases the treadle B from downward pressure, and the treadle is forced to rise by the spring C. As it rises it forces the connect-v ing-rodE and the carriageN upward, and with the carriage N the pawl P also. In rising, the point of the vpawl engages with the upper rightlangled side of one of the recesses in the bottom of which one of the springs W is pivoted, andas it continuesto rise it forces the disk V to revolve thirty. degrees upon its axis. The upward movement of the treadle B also forces the connecting-rod D upward,

and that rod carries the lever G back to its original position,and the lever G, by releasing the disk V from downward pressure, allows the spring U to carry the disk upward to its original positionby means of forcing upward the post T, the carriage S, and the bolt`Y. Then the operation above described as following the replacing of the disk is repeated until the disk has made one revolution and the button-fasteners are all exhausted fromit. Then the bolt Y and the disk V are removed as before, and the disk is replenished with button-fasteners as before, and the subscquently-described operation is repeated. Thus the work is carried on for any length of time desired.

The speed of the machine may be doubled by using two specimens of the disk V and employing two operatives, one of whom is supplying one of the disks with fasteners while bination of the disk V, 'the lock-bolt Y, the the other is using the other disk on the niacarriage S, the post T, and the spring U, subchine in the described manner. i stantially as described. 15
