WINDING CHUCK FOR FABRIC, PAPER, AND OTHER MATERIALS,

Application filed November 8, 1921. Serial I To. 513,314.

'1 0 all whom it may concern Be it known that OTTERBEIN P. KiaAcorn, a citizen of the United States, residing at East Rutherford, in the county of Bergen and State of New Jersey, has invented certain new and useful Improvements in Winding Chucks for Fabric, Paper, and Other Materials, or' which the following is a specification.

This invention has relation to certain new and uset'ul improvements in a winding chuck for fabric, paper and other materials and has for its primary object the provision of a device of this character which will be of extremely simple construction and operation as well as highly eflicient in use and by means of which the material may be readily wound into cylindrical. form without waste of any of the material and without the necessity of I first providing finished tubes upon which to wind the material.

The invention has for another object the provision of a device of the character set forth which will be of such construction and operation that the material may be gripped and held along one edge until the material is wound upon the shell or mandrel and then instantly released to permit withdrawal of the winding device from the wound material, or withdrawal of material from device as occasion may require.

The invention has for another object the provision of a device of the character set forth which will serve to securely hold the ends of the material while being wound into the desired form and size, and then instantly released and the devicewithdrawn from the wound material or materials withdrawn from the device without damage to the material.

The invention has for a further-object the provision of a device of the character stated which will be composed of the minimum number of parts, may be readily assembled or dissembled, as desired and serve to hold the various materials together with any second material which it may be desired to wind into or wind with the first material, the gripping dog being of such construction that it will serve to hold one or more materials in proper position during the winding operation but will permit the material or materials to be readily released when it is desired to withdraw the winding device or the material, as desired.

lVith the foregoing and other objects in view as will appear as the description pro-' ceeds, the invention consists in the novel construction, combination and arrangement of cooperatingelements as hereinafter more specifically set forth, claimed and shown in i looking in the direction indicated by the arrows.

Referringmore in detail tothe drawings in which similar reference characters, designate corresponding parts throughout the several views, 1 indicates the driving spindle which may be provided in its rear end portion with a central bore or other socket 2,

for the reception of a supporting device or driving shaft, not shown. This socket may be smooth, as indicated by dotted lines in Fig. 2 or threaded, as desired. Thedriving spindle 2.has its central portion 3- reduced and the windingshell or mandrel 41: mounted I thereon, a suitable spacing washer 5 being positioned at the end of the shell or mandrel 4L and between the inner end of said shell or mandrel 4L and the larger or rear end portion. of the driving spindle l, as shown clearly in Figs. 1 and 2 of the drawings.

The winding shell or mandrel l has its outer end portion hollow to form the socket 6 within which the gripping dog 7 is positioned. One side of the socket end or outer end portion of the winding shell or mandrel l is open, as shown clearly in Figs. 2, 3 and 4, to 01513 the material receiving slot 8 having one curved or convexed sidewall 9 and a straight opposite side wall 10. The nose 11 of the gripping dog 7 extends into and is adapted to work in the slot 8, as shown clearly in Figs. 3 and 4-. This dog 7 has a curved or convexed wall 12 for one side of the nose 11 thereof while the opposite side of the nose 11 is straight to correspond with the straight wall 10, as clearly shown at 13 in Figs. 3 and 4;. The curved or converted side wall 12 of the nose 11 is positioned opposite and adapted to co-operate with the curved or convened wall 9 of the slot 8 in holding the edge of the material inserted in said slot- 8, as will be later clearly understood. By referring to Fig. 2 of the drawings, it will be clearly seen that the gripping dog 7 is mounted on the reduced forward end portion 14 of the driving spindle 3. The gripping dog 7 is keyed for rotation with the driving spindle 3 by means of the key 15 at the outer end por tion of the driving spindle 3 and the gripping dog 7, as shown in Figs. 2, 3 and 4. A washer 16 is extended over the outer end of the driving spindle 3 and is of sufiicient diameter to cover the end of the locking key 15 and prevent the latter from working out of position. A stop screw 17 is eX- tended through the washer 16 and threaded into the outer extremity of the driving spindle 3, as shown clearly in Fig. 2 of the drawings. This will serve to prevent the washer 6 from moving out of position and releasing the locking key 15 for the grip 'iing dog 7.

It is believed that the complete construction and operation of the winding chuck may now be readily understood without further detailed description. It may be stated, however, that when this device is to be employed for winding material or materials thereon, the end or a portion of the end of the material or materials should be inserted in the slot 8 between the faces 12 of the gripping dog nose 11 and the face '9 o f the slot 8. The entire winding chuck should then be rotated in the proper direction so as to drive this face 12 of the gripping dog 11 toward the wall 9 to grip the material between said walls and hold the material or materials in position while being wound upon the shell or mandrel 4.

hen the winding operation is completed, the first end of the material or materials may be readily released by turning the winding spindle 3 in the direction to move the nose ll of the gripping dog 7 away from the end of the material and release the same, after which the entire winding chuck may be withdrawn from the roll of material, or the material withdrawn from the winding chuck. It is also understood that it is not necessary to grip the entire end of the material or materials to be wound into cylindrical form but a winding operation may be just as effective it only a portion of the end ofthe material or materials are held by the gripping dog 7, in the manner stated. It is also evident that the shape of the shell or mandrel i may be carried as desired.

While the preferred embodiment of the invention has been shown and described, it is to be understood that minor changes in the details of construction and arrangement oi parts may be resorted to within the scope of what is claimed without departing from the spirit of the invention.

What I claim is A winding chuck comprising a driving spindle, a shell mounted on a reduced portion of said spindle and having an eXtended socket portion with the opening forming a material receiving slot, and a gripping dog secured upon said driving spindle within said socket and having a nose extended into said material receiving slot with walls corresponding with the walls of said slot and adapted for cooperation therewith in gripping at times an end portion of a material extended into said slot.

In testimony whereof I aiiix my signature.
