Adjacent the rearward edge thereof the lower plate 36 rests on a rib 42 which is secured to the base plate 1. The plate 36 is formed with a plurality of elongated slots 43, 44 and 45 which extend radial ly with respect to the vertical axis of the plate. The plate is provided with a similar slot 46 which extends across the vertical axis of the plate and which is in longitudinal alignment with the slot 43. Y

The upper plate 37 is of annular construction andis providedin its outer peripheral edge with a recess 48. Fixedly secured to the plate 37, by meansof a clamp 49, is a hollow arm '50within which one end of a bar 51 extends in telescoping relation. A set screw 52 extends through the clamp 49 and upper wall of the arm 50 intoengagement with the bar 51 to provide for the adjustment of the bar longitudinally of the arm. The projecting end of the bar 51 is provided with a bearing 53 through which extends, a vertical shaft 54, the lower end of which projects through the slot 43 in the lower plate 36. Fixedly mounted on the shaft 54, inspaced relation to, the lower end thereof; is a friction roller 55, the periphery of which is adapted to engage the periphery, of a mold 56 when the latter is positioned on the lower plate 36.

Above the bearing 53 the shaft 54 is provided with a pair of spaced sprockets 57 and 58. Secured to the upper plate37, in spaced relation to the hollow arm 50, is a hollow arm 59 which is maintained in position by means of aclamp 60. Extending into the arm 59 in telescoping relation is a bar 61, the projecting end of which is provided with a bearing 62 through which a shaft 63 extends. Theglower end ofthev shaft 63 projects into the slot 44 in the lower plate 36 and spaced from the lower end of the shaft 63, the latter is providedjwith a friction roller 64, the lower edgeof which rests on the upper face of the plate 36 and the peripheral edge of which is adapted to engage the peripheral edge of the mold 56. The roller 64 is normally maintained in engagement. with the mold 56 by means of aspri-ng 65 disposed within the hob low arm 59 and the respective ends of which abut the bar 61 and a bar 66 positioned within the ,arm 59 in spaced relation to the bar 61. I

Pivotally mountedto a'bracket 67 carried by the arm 59 is a latching member 68 which is provided with a nose 69 overlapping the outer end of the arm 59 to prevent the bar 66 from being forced out of the arm 59 by the action of the spring 65.

Secured to the upper plate 37, in spaced relation to the arms 50 and 59, is a hollow arm 70 whichis maintained in position by means of a clamp 71. Extending into the arm 70 in telescoping relation isa bar 72 which may be adjustedlongitudinally of the arm 70 by means ofa set screw 73 extending through the clamp 7 1* and upper wall of the arm 70. The projecting end of the bar 72 is provided with a bearing 74 through which a vertical shaft 75 extends. The lower endof the shaft 75 projects into the slot 45 in the lower-plate 36 and spaced from the lower end thereof, the shaft 75 is provided with a friction roller 76 for engagement with the mold 56. Above the bearing 74, the shaft 75 is provided with a sprocket 77. ,Asimilar sprocket 78 is provided on the shaft 63, above the bearing 62.

Longitudinally adjustable of the arm 50 is a clamp 79 which provides a bearing for a vertical shaft 80. Fixedly mounted on the shaft 80 is a sprocket 81 which is connected by means of a chain 82 with a sprocket 83 on the shaft 26 supported by the bracket 27. Mounted on the shaft 80, in spaced relation to the sprocket 81, is a sprocket 84 which is connected by means of a chain 85 with the sprocket 58 on the vertical shaft 54. En aging the sprockets 57, 77 and'78 'is-an en ess chain 86 which passes over a friction pulley 87 disposed within the recess 48 in the outer peipheral edge of the upper plate 37. The pulley 87 is mounted onone end of shell crank 88 which is ivotally {connected as indicatedat 89 tot e upper plate 37 ofthe carriage; The. opposite end of the bell crank 88 is connected to the hollow arm 70 by means of a spring 90, the tension of-which actuates the bell crank and pulley 87 to prevent slack inthechain86. '-w" w Secured to the base 1 is abracket 91 which is provided with a verticallyrdisposed friction roller 92 for engagement with theforward face of the hollow arm 50 to'prevent any strain from being imparted to the latte'rby the chain 82.

Secured to the rearward end of the frame 3 is a bracket 93 through which a needle holder 94 slidably extends. Carried by thebra'cket 93 is a guide member 95 which is provided with a finger 96' having a bearing 97 through which the needle holder 94 slidably extends. The needle holder 94 is provided witha fixed collar 98 to which one end of a link 99 ispivot'ally connected, the'opposite end of the link 99 being pivotally connected to a b0ss '100 projecti'ngzrearwardly from a disc 101 fixedly secured to the rearward end of the crank shaft 7. The boss-100 is eccentrically disposed with respect to the disc 101 and the link 99 is of slightly greatenlengththanthe radius of; the disc 101. 7 i Adjustably secured to the lower end; of: the needleiholder' 94 1s, a1 needle 102 which carriesa thread 103-which passes upwardly throughvya; guide. .104 T extending.

rearwardly =,fr onrthe' guide member 95.

Extending upwardly from the frame 3is ,a-

supportinggmemben 105ylwhich is provided with a resilient keeper 106 through which the thread 103 extends. In the embodiment shown the thread 103 is formed of four individual' strands indicated at 107, each of which is unwound from a spool 108 rotatably' supported on an extension 109 for one of the upright members 2. Projecting from the supporting member 105 is a tension element 110 which is adapted to hold a block of paraffin or the like indicated at 111. c When it is desired to apply paraflin to the strands of the thread, the element 110 is positioned 111 a manner to provide for the passage of the strands over the paraffin as the strands travel from the spools 108 to the keeper 106! In the operation ofmy'machmeflhe lever 5 is actuated to bring the pulleys 9 and 8 into engagement by means of which the crank shaft 7 is driven by the motor 6. Due tothe cranks 10 and 12 and crank arm 11, theshaft is imparted to the worm shaft23 through the medium of the bevelled gears 21 and 22.

The rotation of the worm shaft 23 causes the cam 28 thereon to reciprocate the lever 31 and due to the link 34 which pivot-ally connects the lever 31 with the carriage 85, the reciprocation of the lever 31 is imparted to the carriage 35 upon which the, mold 56 is seated; The gearing ratio provides for a complete recimocative movement ofthe needle 102 While the carriage 35 is completing one-half of its reciprocating movement. In this manner alternating complete reciprocating movements of the needle will beoon the outside of'the mold and the intermediate movements of. the needlewill he. on the inside, of the mold. During its movements the needle coacts with the bobbin inathe usual manner to form a loop 112. v r "During the operation of the machine a slow rotary movement is imparted to the mold 56 due to "the frictional contact therewith of'the rollers 55, 6 1 and 7 6 whichare actuated by the chains 86, and 82, the latter of which is driven by the sprocket 83 on theshaft26 which is actuatedby means of the gear 25 nieshing withthe wormf24 on the worm shaft 23.3

When it. is desired to changethemold the hell crank 88 ;is, actuated: against; the tension ofthe spring. 90-:to slack-the chain;86.and the compression of. the.:.spring 65 L is released by removing thenose ti9fromth-eiendtof the bar-66.1 Thesroller Gamay thenbe Withdrawn from the mold 56 and the latter. readily removed: from: the machine Duetothe slots 43,. 1ekand45dntthe lower plate 36 andthe adjusting screwslfi2-and; 7 3.. for the barsfil and 72, themachine maybe, usedin covering molds of various sizes.
