WINDING-MACHINE.

To all whom it may concern:

Be it known that I, HERBERT E. SMITH, a citizen of the United States, residing at Manchester, county of Hillsboro, State of New Hampshire, have invented an Improvement in WindingMachines, of which the following description, in connection with theaccompanying drawing, is a specification, like characters on the drawing representing like parts,

This invention relates to winding machines for winding cloth into bolts and to similar machines and, has for an object to provide a safety device which will prevent the accidental rotation of the pivoted stiff-- ening blade and in the preferred form the starting of the machine of this class when the heads and blade are not in proper adjusted position whereby the free end of the blade will be supported during'rotation,

Accidental starting of a machine of this class is particularly dangerous because when the machine is stopped and the bolt of cloth removed the stiffening blade is left free to swing about one end as a pivot. If the operator accidentally moves the startinglever the blade swings as it rotates and causes serious damage to the machine and often serious injury to the operator. Another cause of accident is the careless placing of the cloth board in the machine in such a manner that the free ends of the board and blade are not properly clamped, In accord-- ance with the preferred form'of my present invention I provide a simple and reliable device which prevents the shifting of the operatinglever to start the machine when the parts are in any other position than that in which the ends of the cloth board and stiffening blade are properly engaged and secured.

The novel features of the invention will be fully disclosed in the following specification and accompanying drawings and particularly pointed out in the claims.

Referring to the drawings in which I have illustrated one embodiment ofmy invention, Figure 1 isa back view of a winding machine showing my improved safety device applied thereto, Fig. 2 is a front view of the sliding head and operating device therefor, Fig. 3 is an end view, and Fig. 4 is a detail view of the heads and blade with a cloth board in position.

Referring to the drawings in detail, 1 indicates a supporting frame, 2 and 3 gear Specification of Letters Patent.

casings forming parts of said frame and 4 indicates a drive shaft. Upon the drive shaft are mounted fast and loose pulleys 5 and 6 which are driven by a belt 7. A belt shifter 8 pivotally mounted on the bracket 9 secured to the frame is providedfor shifting the belt 7. 'A shaft 10,is rotatably mounted in the gear casing 2, and is con nectedto the drive shaft by suitable gearing. 'Pivotally mounted'upon the inner end of this shaft is a head 11, to whichis secured a stiffening blade 12. This head is provided with a slotl8 adjacent the blade to receive a cloth board 14:. slidably mounted in the gear case 3, is a shaft 15, to which is rigidly secured a head 16. and this head is slotted to receive the end bf the blade 12- lessthan the length of the lip 19. By this means when the shaft 15 with its head 16 is withdrawn the blade will rest against the lip 19 but may swing past the lip 18 to permit the removal of the board 14 and the cloth wound thereon. Connected to the shaft 15 to move longitudinally therewith but permitting free rotation of the shaft is a frame 20 which is V shaped and provided with the arms 21 and,22. Arod 23 is connected tothe arm 21 and is slidably mounted .in brackets 24' and 25 secured to the gear case 3 and on the end of this rod is a knob 26 positioned to be within convenient reach of the operator. A spring 27 positioned be tween a collar'28 secured to the rod and the bracket 25 urges the rod inwardly and through the connections previously described tends to move the head 16toward the head 11. A latch 29 is positioned to engage a slot 30 in the rod 28 and hold it in its outer position when the head 16 is withdrawn from the end of the blade 12. A springg3l urges the latch toward the rod and insures-its engagement in the slot 30 when the head is moved backto remove a bolt of cloth.

The mechanism so far described except for the shape of the frame 20 is of common and well known construction. I 5

In accordance with my present invention -I provide a safety device whereby it will be.

impossible to operate the belt shifter to" move the belt from the loose to the fast pulley when the head 16 is in its withdrawn position, or when this head has been moved forward and has failed to properly engage the blade, thus avoiding accidents resulting from careless operation.

In the mechanism illustrated a rack 32 is connected to the belt shifter as by a link 33 and is provided with ratchet teeth 84:. A pawl 35 is pivoted to the gear case 3 and is urged toward the ratchet teeth 34 by a spring 36. The construction of the pawl and rack is preferably such that the shifting of swinging the pawl about its pivot to release vent starting of the machine.

the rack 32. If however the cam moves beyond the normal position as it will if the stiffening blade is not in position the pawl will be released to engage the rack and pre By this mechanism when the head 16 is in position to properly engage the blade 12 the pawl 35 is held out of engagement with the ratchet teeth 34- and the belt may be shifted to the fast pulley. If however the head 16 is withdrawn the cam 38 will be at the left of the projection 39 and the pawl 35 will engage the ratchet teeth 34: preventing the shifting of the belt to the fast pulley. If the latch 29 has been raised to release the rod 23 and thereby the head 16 and the head has moved forward under the influence of the spring 27 but has not properly engaged the blade and the board mounted thereon the operation of the belt shifter will still be prevented. For example, if the cloth board and the blade are not properly positioned as the head 16 moves forward the end of the li 18 may engage the end of the board, or i the blade is swung forward beyond the lip 18 the head will move too far forward. In either event the cam 38 will be at one side of the projection 39 and will not hold the detent 35 in released position. a When the head 16 is in proper position holding the board and blade, the cam 38 will engage the projection 39 to hold the pawl away from the rack and the belt shifter will be free to be operated.

It will be clear to one skilled in the art that various modifications may be made without departing from the spirit of the invention as defined in the claims. I

The essential feature of the invention is to provide a device which will prevent accidental rotation of the blade while it is free to swing about its pivotal support.

Having fully described my invention what I claim as new and desire to secure by Letters Patent is l, A machine of the class described comprising alined rotatable elements, a stiffeni'ng blade pivotally connected to one of said rotatable elements and arranged to be clamped by the other rotatable element, a power controlling element movable to cause rotation of said blade and means to prevent movement of the controlling element to cause rotation of the blade except when the blade is properly clamped.
