Specification of Letters Patent.

Patented Sept. 12, 1911.

To all whom it may concern:

Be it known that I, GEORGE S. PRUDEN, a citizen of the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Looms, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to looms and with regard to the more specific features thereof to apparatus of this character for weaving neckties and similar articles.

One of the objects thereof is to provide a practical and efficient loom adapted to change the width of the woven article in any portion thereof by changing the spreading of the warp threads and to simultaneously change the spacing of the weft threads in inverse ratio.

Other objects will be in part obvious and in part pointed out hereinafter.

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the following claims. k

In the accompanying drawing, wherein is shown one of various possible embodiments of this invention, Figure 1 is a diagrammatic side view of a loom; Fig. 2 is a partial front elevation of the loom batten showing the reed frame in operative relation therewith; Fig. 3 is a cross section of the batten taken on line 22-00 of Fig. 2; Fig. 4 is a front view of one of the reeds; Fig. 5 is a plan view of the right hand end of the parts shown in Fig. 2; Fig. 6 is an enlarged detail view of a device to be hereinafter described.

Similar reference characters refer to similar parts throughout the several views of the drawings.

Referring to the drawings, 1 denotes the loom-frame from which is suspended by means of a bracket 2 and bolt 3, the arms 4 which have secured to the lower ends thereof, a horizontally extending batten 5 provided with shuttleguides 6 and having attached to the back thereof two angular members 7 between which the reed-frame 8 is slidably secured. A plurality of inverted said rocker-arms are fastened to a rock-shaft 11 which extends across the top of the machine, supported upon the frame 1 by means of brackets 12. A rocker arm 13 extends in the opposite direction from the rock-shaft and is fastened thereto. A wire 14 serves to connect the arm 13 with a pivotally mounted lever 15 supporting thereon a cam wheel 16. A shaft 17 journaled in any suitable manner has secured thereon a double cam 18 and also a gear wheel 19, the latter adapted to be driven by means of intermediate gearing 20 by a pinion 21 secured to a shaft 22. A ratchet wheel 23 also secured to the shaft '21, has in engagement with the teeth thereof, a pawl member 24 pivoted to a ratchet arm 25 loosely journaled upon said shaft 21. A wire 26 connects the end of this ratchet arm with one branch of a bell-crank lever 27, the other branch of which is connected to one of the batten arms 4 by means of a wire 28. A drive shaft 29 is suitably journaled upon the frame of the machine and has fastened thereto a crank disk 30 provided with a crank pin 31, a pitman 32 jour naled at one end upon said pin is provided at the other end with a pin 33 adapted for adjustment within a slotted member 34 secured to the batten 5.

35 denotes the spools from which the warp threads 36 are led around suitable journaled rods37 whence said warp passes forwardly between the shuttle blocks 6 around a pulley rod 38, thence to the cloth beam 39 upon which the woven articles are wound.

40 indicates the points where the heddles, not shown, engage the warp.

Secured upon the end of the shaft 11 is a forwardly extending arm 41 and suspended from said arm by wire 42 is a rod 43, adapted to slide within a tubular guide 44 fastened to the front of the batten 5, at one end thereof. A similar tubular guide 44 is secured to the batten alongside of guide 44 and slidingly disposed therein is a rod 43 provided with a pin or bolt 45 which extends through a slot 46 in the face of guide 44. A spring 54 secured to the lower end of rod 43 exerts a downward pull thereon and prevents the wire 42 from beam 39.

becoming slack when the rocker arm 41 moves downwardly. Secured to the rod 43 in any suitable manner, as by a stud bolt 55, a bar 56 is provided, which extends transversely from said rod in the direction of and in close proximity to the face of guide 44. When the rod 43 is lifted the said bar 56 will rise. into contact with the pin 45 and the continued upward 'movement of the rod 43 will impart a similar movement to rod 43. A collar 57 adjustably secured to rod 43 by means of a set screw 58 is provided to limit the downward movement of the rod 43 upon said collar coming into engagement with the top of the 'guid'e44, whereby a'limited movement of rod 43 maybe had irrespective of the distance through which rod 43 drops. A ratchet 47 engages the ratchet wheel 48 secured upon a shaft 49 and gearing 5O transmits the motion of the shaft 49 to the cloth Connecting the ratchet 47 with the pin 45 is a cord 51 which is held in any suitable position by means of a pulley 52. A spring 53 also connected at one end to the said ratchet 47 extends in a direction opposite to the cord 51 and has its other end secured to the floor, as shown, or if desired, to a portion of the frame 1.

Having described the present embodiment of thisinvention, the operation thereof, which is largely obvious, follows: The warp having been properly drawn into the heddles and the end thereof operatively connected to the cloth beam 39, upon rotation of the drive shaft 29, a swinging motion is imparted to the batten 5. lVith the swinging of the batten the shuttle moves in. the shuttle blocks 6 in the usual manner to lay the weft thread or filling in the warp. Suitable heddles, not shown, sepa- I rate the elements of the warp to givethe desired weave, which may be single, double or tubular in accordance with the kind of finished article desired. The warp threads pass through the dents in the reed and, by

raising or lowering the latter, the said threads may be spaced fart-her apart or drawn closer together, as the case may be. Hence if a necktie having a narrow neck portion is to be woven, the reed is gradually lowered after theproper length of end has been formed and the narrowing of the tie assumes a regular tapered form until the desired width is attained, when, because of the shape of the cam the reed is held substantially stationary during the weaving of the neckband, after whichthe reed is gradually raised and the tiewidened to form the other end portion thereof. As the batten swings a rotary motion is given to the cam 18 by means of the ratchet 25 transmitted to the rock shaft 11 and the rocker arms 41 and 9 are raised or lowered. Starting with the cam in position shown in Fig. 1, the weaving begins at the short end of the tie and continues forming the full width thereof until the narrower portion of the cam engages the wheel 16, when the reed is gradually lowered and the tie narrowed. Then as the wheel 16 rides upon the opposite end of the cam, the tie widens again and the long end thereof is formed.

'It is to be noted that in the present embodiment the cam is made double so that during a complete revolution thereof, the reed is moved to control the weaving of two complete ties. With the closer spacing of the warp threads it becomes necessary to proportionately increase the spacing of the weft threads to prevent the tie in its narrower portion from becoming too thick and stufi'y. This is accomplished by increasing the rate of feed of the warp through an increased rotation of the cloth beam. As the batten swings a rocking movement will be given the ratchet 47 whichimparts a partial rotation to the cloth beam with every such swing of the batten. By permitting the pin 45 to assume a lower position relative to the batten, the said pin will swing through a greater are and consequently give an increased movement to the cloth beam. Since this lowering of the pin 45 results from the downward movement of rod 43, it isaccomplished simultaneously with the lowering of the reed frame, as the rocker arm 41 shares with the arm 9, the movement imparted thereto by the cam 18. The number of ties that may be simultaneously woven corresponds to the number of separate warps drawn into the loom, which depends upon the number of reeds and shuttles with which the loom is equipped.

It is obvious that many advantages arise from the use of a double cam and prominent among these is the fact that the ties formed from each warp will be joined alternately short end to short end and long end to long end, thus facilitating the cutting apart of the ties, as in each instance the cut will be made at the center of the wider port-ions of the strip wound upon the cloth beam.

From the foregoing it will be seen that the present device is one well adapted to accomplish, among others, all of the ends and objects hereinbefore set forth, in a practical and eflicient manner, and to achieve many advantages in the operation and construction thereof because of the exceeding simplicity of its various parts.

-As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter containedin the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the language used in the following claims is intended to cover all of the generic and specific features of the invention herein described and all statements of the scope of the invention, which, as a matter of language, might be said to fall therebetween.
