Specification of Letters Patent.

Patented Jan. 27, 1920.

Application filed January 30, 1917. Serial No. 145,394.

To all whom it may concern:

Be it known that I, VARTAN KAvonn BADOIAN, a subject of the Sultan of Turkey, residing at Lawrence, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Shuttle-Guards for Looms; and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to improvements in shuttle guards for looms.

The object of the present invention is to improve the construction of shuttle guards for looms and to provide a simple, practical and efficient shuttle guard of strong, durable and inexpensive construction adapted to be readily applied to a loom and capable of effectually preventing the shuttle from flying out and striking an attendant or other person.

Another object of the invention is to provide a shuttle guard of this character adapted to be readily swung upward to afford access to the threads when desired and which will be yieldably maintained in its normal operative position so that it cannot constantly be left in a position that would expose the attendant to a flying shuttle.

lVith these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawing:

Figure 1 is an elevation of a shuttle guard constructed in accordance with this invention and shown applied to a loom.

Fig. 2 is a vertical transverse sectional. view of thesame.

Fig. 3 is a detail sectional view illustrating the construction of the guide rod.

Like numerals of reference designate corresponding parts in the several figures of the drawing.

In the accompanying drawing in which is illustrated the preferred embodiment ofthe invention the shuttle guard comprises in its construction spaced longitudinal rods 1, 2 and 3 extending through and secured in openings 41- of connecting plates 5 by set screws 6, or other suitable fastening devices. The connecting plates are arched or bowed, as shown, to offset the intermediate longitudinal rod 2 from the plane of the other rods 1 and 3. By this construction the guard is bowed or curved transversely.

The guard is supported by brackets 7 of approximately L-shape arranged at intervals and secured by screws 8, or other suitable fastening devices, to the hand rail 9 of the lay 10 of a loom. The L -shaped brackets 7 provide upwardly extending attaching arms and projecting supporting arms which carry clips 11 and which extend beneath the top longitudinal rod 1 of the guard. The top longitudinal rod 1 of the guard extends through and is engaged by the clips 11, which may be secured to the supporting arms in any desired manner.

The longitudinal rod 1 is provided with an upwardly extending arm 12 preferably curved at the upper portion and extending through an opening 13 of a sleeve 14, which is slidably mounted on an approximately iorizontal guide rod 15 rovided at one end with a bracket arm 16. he bracket arm 16 is secured to the loom frame 17 and the guide rod is flattened, as shown, to interlock it with the slidable sleeve 1d. The slidable sleeve 14 is provided with a projecting flange 18, which has the said opening, and a coiled spring 19 bears against the under side of the flange and is suitably mounted on the arm or member 12, which extends upwardly from the guard frame of the shuttle guard. The spring 19 is adapted to act as a cushion to the shuttle guard when moved into an active position. The guide rod 15 is provided with an adjustable stop 20, preferably in the form of a ring 21 secured to the rod by a pin or bolt 23 which is adapted to be arranged in any one of a plurality of perforations 24:, but any other suitable means may be employed for securing the ring or collar 20 to the guide rod. The slidable and yieldable connection between the shuttle guard frame and the guide of the 100111 frame is adapted to accommodate the shuttle guard to the operation of the lay. 'Any number of the slidable guiding connections may be employed to connect the shuttle guard frame with the loom frame. 7

When the lay is in a released position as shown in Fig. 2, the shuttle guard is in a lowermost active position to prevent the shuttle from flying upward out of the shed and when the lay 1O swings forward as in dieated by the arrow to beat in the weft, then the shuttle guard swings upwardly into an uppermost inactive position. When the lay begins to swing forwardly, the sleeve 14 slides on the guide rod into engagement with the stop 20 and upon further movement of the lay, the rod 12 slides through the lug 18 of the sleeve let causing the shuttle guard to swing upwardly into an inactive position.

What is claimed. is:

1. A shuttle guard for looms including a guard, means pivotally securing said guard to the hand rail of the loom, a guide rod secured to the loom frame, a sleeve slida-ble on said rod, means limiting the movement of said sleeve, and a curved rod secured to the guard and slidably connected to the sleeve for swinging the guard upwardly upon the lay of the 100111 swinging forwardly.

2. A shuttle guard for looms including a guard, means plvotally securing said guard to the hand rail of the loom, a guide rod secured to the loom frame, a sleeve slidable on said rod, an adjustable stop on said rod for limiting the movement of said sleeve, an apertured lug carried by said sleeve, and a curved rod secured to the guard and slidable through the opening of the lug for swinging the guard upwardly upon the lay of the loom swinging forwardly.

3. A shuttle guard for looms including a guard, means pivotally securing said guard to the hand railof the loom, a guide rod secured to the loom frame, a sleeve slidable on said rod, an adjustable stop on said rod for limiting the movement of said sleeve, an apertured lug carried 'by said sleeve, a curved arm secured to the guard and slidable through the opening of the lug for swinging the guard upwardly upon the lay of the loom when swinging forwardly, a collar secured to the curved arm, and a spring interposed between the collar and lug for cushioning the guard when moving into active position.

In testimony whereof I a-flix my signature in presence of two witnesses.
