14 Claims. (01 274-45) The present invention relates to mechanism for feeding elongated bodies to a machine and" vices for clamping the same on' the machine and means operating in proper sequence for actuating the parts; and further, to provide improved *speciiic means for this-purpose These and any other objects hereinafter appearing are attained by, and the invention finds preferable embodiment in, the illustrative mechanismparticularly described in the body of this specification and illustrated by the accompanying drawings, in which:

Figure 1 is an elevational front view of mechanism for successively feeding elongated bodies (as the needles or styli of a graphophone) and for releasably clamping the same to a machine part (as to the tone arm of the graphophone),

certain parts 'being sectioned on lines 1-1 and 1a-1a of Figures 2 and '5 respectively;

Figure 2 is'an elevational side view thereof, a portion being broken away;

Figure '5 is a sectional view of certain parts of said mechanism taken on line 5-5 of Figure 1; W 1 Figure 6 is a sectional view of certain parts of said mechanismgtaken on line 6-6 of Figure 1;-

Figure '1 is a top or said mechanism, partially broken away and 9 showing a lever sectioned on line '77 of Figure 2; a

Figure 8 is a detail view of parts of said mechanism sectioned-on line 8-8 of Figure 3;

Figure 9 is a bottom end view of a vertically movable rod with connected parts;

Figures 10, 11 and 12 are end views of a shaft and connected parts, showing the same in diiierent turned positions.

The particular embodiment of -the invention 9 illustrated by these drawings is employed for feeding to; and clamping in, a graphophones tone arm 1 its elongated cylindrical needles or,

styli 2. These needles in vertical position are removably held injhol'es 3 circularly disposed in series in the upper'side of a carrier-4 which is plan view of certain parts.

turnable in its bearing 5 in the upper end oi a squared rod 6 vertically slidable in a bearing '7 in the mechanisms frame 8. In Figure lythis carrier is shown in solid lines in its lowered position from which it is raised to dotted line position to insert into the socket 9 of the tone arm the particular needle which has been brought, by a previous turning movement of the carrier, into registration with. this'socket. The

carrier is raised to its dotted line position (Figure 1) by the turning of'a disk10 having in its inner side a cam groove 11 in which travels the roll 12- on an arm of the flever.13 fulcrumed at. 14, whose other arm 15 is connected to a link 16 pivoted at 1'7 on said squared rod 6.

As seen in Figure 1, a worn needle 2 is about to be released from the tone arm and replaced. with a new needle 2 taken from the carrier. To do this, the cycle of themechanisms operation is as follows: The 'disk 10 is rotated so that the peripheral cam groove 38 moves the roll 37 on one'arm 36 0! a lever 31 (fulcrumed at 32) into the portion 60 of said groove 38 and thereby slides the shaft 2'7 (rotatably mounted at '61 on the frame) toward the left hand side of Figures 1 and 3 thereby causing the kerf 39 in the end of said shaits member 40 to engage the diametrical rib 41 on the end or head-i2 of a set screw 43. threaded in the tone arm and extending into its socket 9 and into engagement with theneedle 2 to clamp the same therein. The shaft 2'7, act-" ing as a screw driver, is rotated to turn said screw sufllcientlyto release this needle 2 by means of the rotation of said disk on whose crank wrist pin 25 is carried a rack 24 meshing with a gear 26 to turn said. shaft 2'1. The

needle 2 thus released falls 'out of socket screw 43 reversely. and into binding engagement with the needle which has just been inserted into the socket, whereupon said disk's further turning movement causes the roll 12 to pass into the dwell 18 and. restores the parts to initial position shown in solid linesin Figure-1.

For the purpose of cushioning-the action, the gear 26 has ap'in 29 and the shaft 27 hasa pin 30 Connected by a coiled spring 28. Normally these pins are in the abutting relation The turning movement of the shaft with its member 40 in contact with the screws rib 41, but before the rib 41 is in alignment and engagement with the kerf 39 is thus permitted, and is also permitted by the,axial movement of said member splined to said shaft by its screw key 44 engaging in the shafts longitudinal groove 45, said member being pressed outwardly by the spring 46. At a point in the lowering movement of the carrier, one'of the circularly disposed teeth 19 on its under side engages the pawl arm 20 of a bell crank lever 21 fulcrumed at 22, and the continued downward movement of the carrier in such engagement causes the carrier to turn a suflicient distance to bring the next succeeding needle 2 held thereby into registration with said socket for insertion, thereinto on the next rising movement of the carrier. The carrier is held against reverse turning by the detent 51 pressed into engagement with one of said teeth by the spring 52.

The disk 10 may be rotated to operate the said mechanism by any suitable means, as by connections with the driving or operating means of the graphophone or other machine to which said mechanism is applied, and at intervals for replacing such worn elongated bodies, as the worn needles of a graphophone. shown is in the form of a gear meshing with a driving gear 49. The rack 24 bears slidably in a turnably mounted block 50. The wrist pin 25 is carried by a block 53 slidable to adjusted positions' in a diametrical groove 54 in the disks portion 23 and held in such positions by the nut 56. When a needle 2 is released from said socket it falls into a chute 47. This chute has a springable upper end or trough 48 (shown in solid lines in its normal position) in which the discarded needle 2 is guided into the chute.

Thereafter, the rising movement of the carrier to insert a new needle into the socket slides at its edge alongsaid end 48 and springs it to dotted line position (shown in Figure 1) out of the way of said new needle. erative movement its tone arm swings past its position in which the needle is inserted into its .socket and the carrier is lowered to permit said "end 48 to spring back to its solid line position.
