GEORGE E. HUTO-HINS, OF WOROESTER, MASSACHUSETTS, ASSIGNOR TO THE OROMPTON & KNOWLES LOOM WORKS, OF SAME PLACE.

LOOM.

SPECIFICATION forming part of Letters Patent No. 606,553, dated June 28, 1898 Application filed January 10,1898. 7 Serial No. 666,148. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE F, HUToHINs, a citizen of the United States, residing at WVorcester, in, the county of Worcester and State of Massachusetts, have invented certain new and usefullmprovements in Looms,

v of which the following is a specification.

My invention relates to looms, and more particularly to a supplemental mechanism to be applied to and used upon wide looms for. weaving thick or heavy fabrics, such as duck! cloth, &c., to prevent any bending or back spring of the layintermediate its connections with the crank-shaft when the lay is in its forward position. V

The object of my invention is to provide a simple and effective mechanism adapted to be applied to and combined with looms of ordinary construction of the class'above re: ferred to and forthe purpose above stated; and my invention consistsin certain novel features of construction of my mechanism, as will be hereinafter fully described.

Referring to the drawings, Figure 1 is a rear perspective view of portions of a loom with my improvements applied thereto; and Fig. 2 is a plan view, on an enlarged scale, of my supplemental mechanism shown in Fig. 1.

In the accompanying drawings, 1 is a loom side or end. '2 is a loom center. 3 is the driver-shaft, and 3 the driving-pinion. 4 is the bottom shaft 4; is the crank-shaft. 5 and 6 are intermediate gears. 7 is the crankconnector. 8 is the lay; 9, one of the layswords, secured at its lower end on the rockershaft 10. 11 is the hand-rail, and 12 a portion of the reed. All of the foregoing parts may be of the ordinary and usual construction.

I will now describe my supplemental mechanism.

On the bottom shaft 4L is fast a gear 13, which meshes with a gear 14:, fast on a short shaft 15, journaledin bearings 16 on the crossgirth 17 and loomcenter 2. (See Fig. 2.) On the end of the shaft 15 is fast a crank disk or wheel 18, and on the pin or stud 19 there is loosely mounted a roll 20. A lay-sword 21, located intermediate the end lay-swords 9, is secured at its upper end to the rear portion of the lay 8 and secured at its lower end on removable and adjustable by bolts 23 or otherwise.

The cam -surface 22 is so arranged relathe rocker-shaft 10 and has a curved or cam surface 22 thereon, which is preferably made tively to the roll 20 on the crank-disk19 and the revolution of said disk is so timed that when the lay is very near its forward position on its forward stroke the roll 20 will be j and bring it into alinement when the lay is at its extreme forward movement, thus beating up the cloth in'a straight line the full length of the lay.

In the ordinary Weavin g of the loom, in case there is no back spring of the lay, the roll 20 .may be carried around with the disk 18 and pass by the cam-surface 22 on the stand 21 on the forward stroke of the lay without any engagement therewith.

By the construction of my mechanism it will be seen that the roll 20 is in position to engage the cam-surface 22 on the stand 21 only during a portion of a'revolution of the disk 18, and during the rest of the revolution of said disk there is no engagementm possibility-of engagement between the roll 20 and cam-surface 22. Thisis an advantage, as it reduces Very much the friction on the parts and any loss of power.

I have shown in the drawings only one center lay-sword 21 and one crank disk or wheel 18 and engaging roll 20; but it will be understood that there can be one or more on the 100111, according to the width of the 100m.

It will be understood that the details of construction of some of the parts of my improvements may be varied, if desired. For example, a crank-arm carrying the roll 20 may be used in place of the disk or wheel 18, as indicated by dotted lines 21, Fig. 1. The roll 20 may be dispensed with and only a stud or pin used.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In aloom, the combination with the lay,

and means for actuating the same, and a laysWord intermediate the end lay-swords, having a curved or cam surface thereon, to be engaged by a roll or pin on a crank disk or arm, of said crank disk or arm carrying a roll or pin to engage said curved or cam surface during a portion only of the revolution of said crank, and means for supporting and revolving said crank, substantially as shown and described.

2. In a loom, the combination with the lay, and means for actuating the same, and a laysword intermediate the end lay-swords, havporting and revolving said crank, substan- 2o tially as shown and described.
