EDWARD WIN FRED TURNER, 0F SWANSBORO, AND HERMAN SEGAR BEAMS, OF RICH- MOND, VIRGINIA, ASSIGNORS TO RICHMOND CEDAR WORKS, OF RICHMOND, VIR- GINIA, A CORPORATION OF VIRGINIA.

MACHINE FOR MAKING CLOTHES-PINS.

Application filed January 15, 1907, Serial No. 352,459.

To all whom it may concern Be it known that we, EDWARD VVINFRED TURNER and IIERMAN Susan limits, citizens of the United States, residing, respectively, at Swansboro and Richmond, in the counties of Chesterfield and Hcnrico, State of Virginia, have invented a new and useful Machine for Making Clothes-Pins, of which the following is a specification.

This invention relates to machines for shaping, slotting and stamping clothes pins and its object is to provide mechanism whereby strips of wood or other material from which pins are to be made will be carried through the machine and successively shaped, stamped and slotted and then delivered from the machine in a finished condition ready for the market.

Another object is to provide novel mechanism actuated from a common drive shaftwhereupon the proper actuation of the parts for producing the successive operations will be accomplished.

A still further object is to provide novel means for feeding the stock intermittently through the machine so as to enable various operations to be performed while the feed is at rest and while the pin blank being operated upon is retained in a single seat of the conveyer.

With these and other objects in view the invention consists of certain novel features of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claims.

In the accompanying drawings is shown the preferred form of the invention.

In said drawings: Figure 1 is a plan view of the machine, parts thereof being broken away. Fig. 2 is an elevation of that portion of the mechanism at one side of the machine, all other parts of the mechanism being removed for the sake of clearness, the direction in which the elevation is taken being indicated by the arrow a in Fig. 1. Fig. 3 is an elevation of that portion of the mechanism at the opposite side of the machine, all other parts of the mechanism being ren'ioved for the sake of clearness, the direction in which said elevation is taken being indicated by the arrow 7) in Fig. 1. Fig. 4t is a front elevation of the machine, the carrier and its pulley and frame being removed and certain other parts of the machine being broken Specification of Letters Patent.

away. Figs. 5, 6, 7 and 8 are views showing the successive forms of the stock when passing through the machine. Fig. 9 is a view showing in perspective and in edge view the worm employed for producing intermittent rotary motion.

lteferring to the figures by characters of reference, A is the frame of the machine having a main or drive shaft 1 extending from. front to rear thereof and provided with a drive pulley 2 adapted to receive motion from any suitable source. Mounted in bearings formed with the frame A at the front and rear thereof are the trunnions 4 of the rock frame 5 of the slotting apparatus B. This frame is adapted to swing upon its trunnions in a plane extending from side to side of the machine and has standard (3 in which is journaled a shaft 7. This shaft carries a pulley 8 engaged by a belt 9 from a pulley 10 secured to the drive shaft 1. Secured in any suitable manner to one end of the shaft 7 is a slotting disk 11 in the form of a circular saw the thickness of which is equal to the width of the slot to be cut in a pin. Extending from opposite faces of this disk 11, are blades 12 preferably four in number which are secured to the disk in any preferred manner and are so shaped as to enlarge the slot within the pin, as shown at 13 in Fig. 8. These blades 12 are disposed at a distance from the periphery of the disk 11 equal to the distance between the inner end 1 1 of the slot of the finished clothes pin and the inner end 15 of the flare 13, as shown in Fig. 8. i

An intermediate shaft 16 is journaled within the frame A and carries a gear 17 which meshes with a smaller gear 17 011 a shaft 18. A loose pulley 18 and a fixed pulley 18 are arranged on shaft 18 and either is adapted to be driven by a belt 19' extending over a pulley 19 on shaft 1. Secured to shaft 16 is a double cam 20 composed of two disks parallel and grooved on their neighboring surfaces to form a. single cam path. A follower rod 21 having rollers 24 which engage the cam grooves projects therebetween. The rod is formed in sections secured together by a turn buckle 22 and slides and swings in bearing 21" in the frame of the machine. This rod 21 is pivotally connected to an arm 23 extending from the rock frame 5 of the slotting mechanism B. Rollers 24 extend laterally from one end of the rod 21 and ride within the adjoining grooves -of the cam 20 and said cam is so shaped that when the shaft 16 is rotated the frame.5 will be swung slowly toward the right of the machine so as to feed the disk 11 into the stock to be slotted and as soon as this slotting operation is completed the cam will,.by reason of its peculiar form, quickly Withdraw the disk from the slot. By means of the turnbuckle 22 the rod 21 can be lengthened or shortened so as to increase or diminish the depth of the slot to be cut by the disk.

The slotting disk 11 is disposed in a vertical plane intersecting the center of the drum 25 of the conveying mechanism 0. This drum is in the form of a short cylinder mounted to rotate as hereinafter described. In the cylindrical surface of the drum are grooves 25 parallel to the axis. These grooves serve as seats for the stock. The seats are slotted longitudinally to admit the slotting cutter. These longitudinal slots which are numbered 26 are widened at the mouth to guide the saw or slotting disk in entering. It is of course understood that that end of the drum 25 facing the disk 11 is open so that said disk is free to pass into any one of the slots 26 when the rock frame 5 is swung in one direction. Drum 25 is secured to a shaft 27 which is journaled in the sides of frame A and carries a worm gear 28 which is engaged by a worm 29 on shaft 16. This worm 29 is formed of a disk having outstanding blades 29 which are so shaped as to engage the gear 28 during a fraction of the rotation of the worm 29 and to turn said gear one notch or tooth during said engagement, said gear 28 remaining stationary during the remainder of the rotation of worm 29. As a result of this arrangement the conveyer drum 25 will be rotated intermittently or step by step as will be obvious.

Secured upon the shaft 27 at one side of the drum 25 is a pulley 30 adapted to drive a belt or cord 31 extending over a pulley 32. The latter drives the feed mechanism 1) of the machine. This mechanism comprises side strips 33 which are pivotally secured to standards 34 extending from the frame A and have side brackets 35 adjustably supported by bolts mounted in brackets 37. By adjusting the nuts 38 on these bolts the side strips 33 can be swung upward or downward so as to cause the feed apparatus to assume a position at a desired angle to the horizontal. A guide strip 39 is disposed above and between the side strips 33 and has its outer end upturned as shown at 40. Pulley 32 is secured to a shaft 41 which is journaled in the outer ends of the side strips 33 and carries sprockets 42 in which are mounted endless chains 43 carrying a conveyer belt or apron 44. This apron extends around a roller 45 disposed between the side strips 33 close to the drum 25 and is adapted to feed the stock to the drum so that each seat upon said drum will receive one of the stock as said drum rotates. A suitable tightener 46 is mounted on the frame A so as to keep the belt or pulley 31 taut. Obviously when the'stock is placed upon the conveyer the upturned end 40 of the guide 39 directs the articles downward under the guide and they will be positively fed to the drum. The gear is so proportioned that the articles on the feed belt or apron will be discharged one at a time into the successive seats within the drum.

In order that the stock may be properly shaped after it has been fed to the conveyer drum 25 shaping mechanism E is utilized. This mechanism consists of a rocking frame 47 having trunnions 48 j ournaled in inwardly extending brackets 49 on frame A and a shaft 50 is jo-urnaled in the upper end of the rocking frame 47 and carries a shaping head 51 having blades 52 outstanding therefrom with their edges so shaped as to produce pins of the desired contour. Shaft 50 has a pulley 53 thereon which is driven by a belt 54 extending under a pulley 55 on the main shaft 1. The rocking frame 47 of the cutter head 51 has a rigidarm 56 extending therefrom and bearing against the working face of a cam 57 secured to the shaft 16. This cam is so shaped as to swing arm 56 laterally or toward the front of the machine while the conveyer drum is being moved and while said drum is at rest the cam 57 permits the arm 56 to swing toward the back of the machine and thereby cause the cutter head to move by gravity against the stock upon the drum 25 and adjacent the cutter head.

Co5perating with the cutter head is a centering and holding apparatus F of novel form. This apparatus consists of a spindle 58 which is rotatably mounted in a bracket 59 mounted on frame A and said spindle is connected by a universal joint 60 with a shaft 61 mounted in suitable bearings 62. This shaft has a beveled gear 63 which meshes with a gear 64 on shaft 16. The free end of the spindle 58 is toothed or serrated so as to engage one end of the stock fed into alinement therewith and this spindle is constantly rotated by means of he mechanism described. Cotiperating with the spindle 58 is acenter 65 which is normally projected toward'spindle 58 by means of a spring 66. This center is slidably mounted within a bracket 67 on frame A and is pivotally connected to the upper end of a lever 68 the lower end of which is fulcrumed to the frame A, as shown at 69.

A rod 70 is pivoted to the lever 68 at a point between its ends and also to the intermediate portion of a lever 71 fulcrumed at its lower end upon a bracket 72 disposed at the opposite side of frame A. This lever 71 has a lateral projection 71' at its upper end which is engaged by a cam 73 secured to and rotatable with shaft 16. The cam and the mechanism operated thereby are so proportioned that while the drum 25 is moving the center is held retracted within its supporting bracket 67. WVhen, however, the drum comes to a stop with one of the stock in position between the spindle 58 and the bracket 67 the cam 73 will actuate lever 71 so as to cause the rod and lever 68 to push the center (55 forward into engagement with one end of the stock and thereby force said stock against the toothed end of the spindle 58. The stock will therefore be rapidly rotated while the rotating cutter head 51 is in contact therewith. Immediately prior to the next movement of the drum the center 65 is withdrawn from engagement with the stock by its actuating apparatus and the cutter head is swung away from the stockas heretofore described so that the drum is free to convey the stock one step forward toward the slotting disk 11.

J ustas the stock is brought into position to be slotted by disk 11 and immediately prior to the slotting operation said stock is clamped and held by stamping mechanism G. This mechanism consists of a die 74 suitably guided pivotally connected as at 75 to one end of a lever 76 which is fulcrumed upon an arcuate plate 77 secured to one end of the frame A. This plate, as shown in Fig. 2, extends across one end of the upper seats 26 and to the right of the drum 25 and thereby serves to prevent longitudinal displacement of the stock while the same is being slotted. The horizontal portion of the-plate 77 is slotted at 77 to admit the cutter. Lever 7 6 is connected by means of a rod 78 to a lever 79 fulcrumed at a point between its ends and contacting at its free end with a cam 80 mounted on the shaft 16. The cam is so arranged in relation to the balance of the mechanism that each time the drum 25 comes to a rest the die 74 is pushed downward so as to stamp an .object which is upon the drum and in position to receive the slotting disk 11. This die will be held in clamping position throughout the slotting operation and will be raised from the object simultaneously with the removal of the slotting disk from the stock. Said die therefore not only serves to properly mark each object formed within the machine but it also acts as a holder to maintain the object in a fixed position during the slotting operation.

It will be understood from the foregoing description that articles of uniform length may be fed to the machine upon the apron 4 1 and will be distributed within the seats in the periphery of drum 25. These articles will then be moved step by step with the drum and will be brought successively into position between the center (35 and spindle 58 where each article will be rotated and acted upon by the cutter head 51. The articles will then be carried step by step into position in front of the slotting disk 11 at which point each article will be successively stamped and held by the die 7st and the rocking frame 5 will be swung toward the die so as to move the rotating disk 11 slowly into the article and slot it. The blades 12 upon the disk will flare the end of the slot, as shown at 13 and as soon as the slotting operation has been completed the disk will be quickly withdrawn from the slotand drum and the die will be raised. The drum will then again move forward bringing another article in position to be slotted and the finished articles will subsequently be discharged from the drum at the rear of the machine. It will be seen that the mechanism required for producing the pins is comparatively simple and extreme importance is attached to the provision of a combined clamp and die whereby a suitable trade mark or arrangement of words, etc, can be stamped into the body of the object.

Importance is attached to the fact that the saw 11 moves into the slots in drum 25 while slotting pins and that the pins are disposed entirely within the slotted seats in the drum. As a result of this construction each pin is supported throughout its length by the drum and there is no danger of the pins being broken when subjected to the action of the saw. Moreover, as the slots in the drum are but little wider than the cut produced by the saw it will be apparent that the pins will be firmly supported. by the drum close to the cut and tearing of the wood therefore prevented.
