The invention finally consists in the comkeyed to said shaft, a disk 34C, mounted to slide bination and arrangement of parts set forth longitudinally upon said shaft, and a pulley 35 in the following' specification, and particularly interposed between said disks loosely mounted pointed out in the claims thereof. upon the shaft 32, said disk 34 being pressed Referring' to the drawings, Figurelisa side against the side of the pulley 35 by a spiral 95 elevation of my improved machine for sepaspring 36, one end of which bears against said rating' and driving' headless pointed pins. Fig. pulley, the other end thereof bearing against a 2 is a plan view of the same. Fig. 3 is an encollar37, fast to the shaft 32. Thepulley35 is larged section taken on line 3 3 of Figa. Fig. rotated by a belt 38, driven by a pulley 89, 4 is a section, partly in elevation, taken on formed upon the hub of a cam 40, fast to the IOO main driving-shaft 16. A rotary motion is imparted to the shaft 16 by a pulley 41, fast thereto.

The pins are fed out of the hopper 18 by a feed-w heel 43, fast to the shaft 32. Said feedwheel is provided upon its periphery with transverse grooves 44, said grooves being' of such size and depth as to receive, preferably, only three pins. rlhe feed-wheel 43 is also provided with an annular groove 45 in its periphery extending entirely therearound and located mid way between the two opposite faces thereof. A raceway 46, tangential to the feedwlieel 43, extends therefrom to a separating device 47. A portion 48 of the raceway 46 extends into and partly around the groove 45, terminating below the bottom of the hopper 18. The pins are taken by the feed-wheel 43, as illustrated in Fig. 6, from the hopper 18 and carried in the direction of the arrow c, in said ligure upwardly and onto the raceway 46, beneath a cap 49, located above said raceway. The raceway 46 guides the pins 17 to the separater 47.

The separator 47 consists, preferably, of a 4cylindrical casing 50, in which is journaled a carrier 51, to which a rockingmotion is imparted by an arm 52, fast thereto and connected by a link 53 to a lever 54, pivoted at 55 to the frame 15. A rocking motion is imparted to the lever 54 by an eccentric 56, fast to the main shaft 16 and connected by an eccentricstrap 57 and rod 58 to the lever 54. ln order to prevent the pins from being' jammed in the separator 47, the link 53 is provided with a slot 59, through which a screw 60 projects, fast to the lever 54, a spiral tension-springl being connected from the screw 60 to the link 53.

The casing 50 is provided with an inlet-passage 62, into which one end of the raceway 46 projects. Said casing is also provided with an outlet-passage 63, through which the pins pass after being separated one from the other, as hereinafter described. The carrier 51 is provided in its periphery with a groove 64, extending longitudinally thereof. Said carrier rocks in a cylindrical chamber 65, formed in the easing 50,'and adjacent to the opposite ends of said carrier grooves 66 and 67 are formed in the casing 50 concentric with the carrier 51 and in line with the groove 64. The passage 63 opens into a chute 68, said chute being provided with two passages 69 and 70, which form an acute angle one with the other. The passage 70 terminates adjacent to a vertical recess 71, formed in a holder 72, said holder terniinating a't its upper end in a sleeve 73, which is clamped in a groove in the frame 15 by a. cap 74 and screws 75. The sleeve 73 in addition to supporting the holder 72 constitutes a bearing in which the cylindrical driver-bar 76 is adapted to slide. r1`he driver-bar 76 is connected by a link 77 to the lever 54, from which it receives a reciprocatory motion, and to the lower end of said driver-bar is fastened a driver 78.

A guide-sleeve 79 is arranged to slide upon the lower end of the driver-bar 76 and is held thereon by a screw 80, which projects through a slot 81, provided in said sleeve, said screw also serving' to attach the driver 78 to the driver-bar 76. A spiral compression-spring 82 encircles the driver-bar 76, the upper end thereof bearing against a shoulder 83, formed upon said driver-bar, and the lower end bearing against the top of the sleeve 79. The lower end of the driver 78 projects through a hole 84, formed in the bottom of the guidesleeve 79.

The material 85, into which the pins are to be driven, is placed upon the top of the worktable 86, and the point of the pin which projects below the material after having been driven therein, as hereinafter described, is cut off by knives 87 87, fast to slides 88 88, arranged to slide in ways 89, formed in said work-table. The slides 88 are forced away from each other by a spiral spring 90, interposed between their adjacent ends, and are moved toward one another by levers 91 92, pivoted at 93 94, respectively, to the frame 15. A rocking motion is imparted to the levers 91 92 by cams 40 and 95, respectively. In the end of each of the levers 91. and 92 is a stud 96, having screw-threaded engagement therewith, by means of which the distance of the slides apart may be varied at either extreme of the movement of said levers 91 and 92. The work-table 86 is fast to a standard 97, which projects downwardly through a bore 98, formed in the frame 15. Said standard 97 has screw-threaded engagement with an adjusting-wheel 99 and is clamped rigidly in position upon the frame 15 by clamp-screws 100 100.

The raceway 46, Fig. 2, has two sides 101 and 102, which form a guideway 103 for the pins as they pass from the feed-wheel 43 to the separator 47, and, as will be seen in Fig. 2, said sides converge as they approach said separator. The opposite side walls 104 and 105 of the iiilet-j'rassag'e 62 form a continuation of the guideway 103, and said side walls also converge toward one another to the periphery of the carrier 51, Fig. 7. 1n order to keep the pins 17 in the raceway 46 as they pass from the feed-wheel to the separator, a cover 49 is provided which extends partly across the guide-way 103, is forlned in a curve at its upper end to admit the pins therebeneath, and is cut awa-y upon its under side near the lower end thereof to allow the pins as they approach the carrier to roll down the raceway into contact with the periphery of said carrier without being impeded by the friction of said cover. The cover 49 is held downwardly by springs 107, located in recesses 108, formed in cross-pieces 109, fast to the IOO IlO

sides of the raceway 46, and said cover 49 is,

moreover, guided by pins 110. fast thereto and projecting upwardly therefrom through said cross-pieces.

The general operation of my improved machine for separating headless pointed pins is as follows: The pins 17 in the hopper 18 are taken by the feed-wheel 43, as illustrated in Fig. 6, and carried in the direction of the arrow ay in said figure upwardly and beneath the cover 49 into the guideway 103, formed between the sides 101 and 102 of the raceway 46. Said pins are prevented from passing around with the feed-wheel by the portion 48 of said raceway, which guides them away from the wheel at the right-hand side thereof, Fig. 6, and beneath said cover 49 down the guideway 103 until they arrive near the lower end of said raceway, when the cover being cut away upon the under side thereof the last few pins upon the raceway (ve in number, as indicated in Fig. 6.) roll by gravity downwardly upon the raceway and between the converging side walls 104 and 105 of the inlet-passage 62 until they enter one by one the groove 64 in the rocking carrier 51. Upon the carrier being rocked the pin contained in the groove 64 is carried by said carrier forward in the direction opposite to the arrow Fig. 6. Referri ng to Fig.7, it will be seen that as the pin is carried forward, as hereinbefore described, by the carrier 51 if the point thereof is located at the left, Fig. 7, it will enter the groove 67, being positively forced into said groove by the inclined side wall 104, and when the carrier 51 has been rotated until the pin is brought in line with the outlet-passage 63 said pin will drop downwardly first at its free or blunt end, as illustrated in Fig. 7, the point extending upwardly, and will pass out of said passage 63into the passage 69 to the position shown in dotted lines in the passage 70, Fig. 6. It will then slide by the force 'of gravity down said passage into the recess 71, as illustrated in Fig. 3. If, on the other hand, the pin enters the groove 64 in the carrier, with the point thereof extended toward the right, Fig. 7, the converging side wall 105 will force said pin toward the right and the point of the pin will enter the annular groove 66. lhe result, however, as to feeding the pin with the pointed end extending upwardly from the carrier to the chute will be the same as in the case where the pin had the pointed end thereof extended toward the left in said Fig'. 7, for the free end of said pin will drop first when it is brought in line with the outlet-passage 63, and thus said pin will pass into the chutepassage 69 to the position illustrated in dotted lines, Fig. 6, in the passage 70, and thence will slide down into the recess 71 in the holder 72. Then the pin drops into the recess 71, it is prevented from passing downwardly therefrom by a slide 111, Figl 3, which is held toward the right, with its end projecting into the recess 71, by a lever 112, pivoted to the holder 72 at 113 and held in the position illustrated by a spiral spring 114. Assuming the pin now to be standing' in the recess 71, as illustrated in Fig. 3, the machine is so timed that the driver-bar 76 moves downwardly until the lower end of the sleeve 79 cornes in contact with the top of said pin. It will be noted that said sleeve has a concavity 115 in the under side thereof for the purpose of moving the pin into a vertical position if it happens to be standing at an angle in the recess 71. The driver-bar 76, driver 78, and sleeve 79 descend until the bottom of said sleeve rests upon the holder 72. Upon a continued downward movement of the driver-bar the driver forces the pin through the recess 71 and into the material 85. The knives 87 are now forced toward each other by the levers 91 and 92 and the point of the pin cut off.

In Fig. 9 a development of the side walls 104 and 105, together with the grooves 66 and 67 formed therein, respectively, is illustrated with pins in the position they would assume when being carried through between said side walls by the rotation of the carrier 51. It is evident that without departing from the spirit of my invention the carrier 51 may be made to continuously rotate instead of being rocked, as hereinbefore described, or said carrier may be made a reciprocatory carrier, the broad principle of the invention being that a mov- 4ing carrier provided with a groove to receive a headless pointed pin carries said pin between two converging' side walls, each provided with a groove, the pointed end of the pin passing into one of said grooves according to the direction in which said pointed end is extended, and when said pin has been moved by the carrier to a point opposite the exitpassage the blunt end of said pin will drop downwardly while the pointed end still remains in the groove, thus insuring a positive feed of the pins one by one, with the points all extending in the same direction.

Having thus described my invention, what I claim, and desire by Letters Patent to secure, is-- 1. In a machine for feeding and separating pointed headless pins, a carrier, acasing therefor provided with an inlet and an outlet passage and guides for said pins, said guides provided with grooves located adjacent to opposite ends, respectively, of said carrier and adapted to receive the points of said pins.
