LUG-STRAP SUPPORT FOR LOOMS.

Specification of Letters Patent.

Patented June 19, 1917.

Application filed. December 1, 1916. Serial No. 134,364.

To all whom it may concern:

Be it known that I, CHARLES FABER, a citizen of the United States, residing at Bridgewater, in the county of Plymouth and State of Massachusetts, have invented certain new and useful Improvements in Lug-Strap Supports for Looms; and I do declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the 'art to which it appertains to make and use the same.

This invention relatesto new and useful improvements in loom attachments, and the primary object of the invention is to provide a means whereby the wearing of the picker stick and lug strap is reduced to a minimum, and the essential features-of the invention are to provide a new and improved type of holder between the picker stick and lug strap that is adjustable so that the lug strap may be raised or lowered, as desired.

Another object of the invention is'to pro .vide a device of this character .which is easily and simply constructed, inexpensive to manufacture, and one which will be very efficient in operation.

With the foregoing and other objects in' view, the invention consists of the novel features of construction, combination and arrangement of parts, which will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings Figure 1 is a detail perspective of the device applied;

Fig. 2 is a perspective of one end of the holder; 2 I

Figs. 3 and 1 are detail perspectives of the lower end of the holder.

In describing my'invention I shall refer to the drawings in which similar reference characters designate corresponding parts throughout the several views. The numeral 1 designates a picker stick which is of the ordinary type used in looms of the character to which this device is applicable, and which is provided adjacent its head with the usual projection 2 thereon. The type of lug strap 3 illustrated in the accompanying drawings is covered by Letters Patent No. 7 07,406, and which is the type commonly used in this character of devices. However, any lug strap that is provided with a yoke 4 that surrounds the picker stick 1 may be employed. The outer end of the lug strap 3 is connected with a rocker arm 5 by a hinge connection, as clearly shown at 6 in the drawings. I

My invention essentially relates to the connection between the yoke of the lug strap that surrounds the picker stick and the picker stick. This connection comprises a coupling member 7 which has its upper end pivotally and detachably connected with the picker stick, while the lower end of the same is pivotally and detachably connected with the yoke of the lug strap. This coupling member is disposed adjacent the outer side of the picker stick and parallel therewith, and the member is longitudinally adjustable so as to raise or lower the lug strap as desired.

The coupling member 7 is formed in two parts, one of the parts, which is designated by the numeral 8, being formed of a rod with its upper end flattened and having a spring hook 9 formed thereon. The lower end of the rod 8 is externally threaded as shown at 10 for a purpose to be hereinafter more fully described. The upper end of the rod 8 is connected with the picker stick 1 adjacent its upper end by meansof a flat plate 11 secured to the outer side of the picker stick, as shown at 12, and this plate is provided with oppositely bent angular upper and lower portions 13 and 1 1-. The upper portion is adapted to engage the opposite sides of the picker stick, while the lower portion has a horizontally disposed pivot bar 15 positioned between its sides. The spring hook9 on the upper end of the bar 8 is adapted to engage the pivot bar 15, whereby the coupling member will be pivotally and detachably connected with the picker stick.

The lower portion of the coupling member 7 is formed from a flat metal strap 16 which has on its lower end a spring hook 17. Secured to the outer'side of the yoke l of the lug strap is a hinge member 18, that projects upwardly therefrom and has mounted between its projecting portions a pivot bar 19. The springhook 1-7 of the strap 16 is adapted to engage the bar 19, whereby the strap at the lower end of the coupling member will be pivotally and detachably connected with the yoke of the lug in which the lower end of the rod 8 is slidably mounted. This lower end of the rod is provided with a pair of nuts 22 that are disposed on opposite sides of the extension, and owing to the fact that the lower end of the rod is externally threaded, these nuts are adapted to lock the extension at various longitudinally adjusted positions along said rod. By this means it is obvious that by releasing the nuts 22 the strap may be moved along the rod, and owing to the fact that the strap is connected with the lug strap 3, this lug strap will be raised or lowered accordingly. Upon tightening the nuts 22 against opposite sides of the extension, the strap 16 will be securely locked in position.

From the foregoing description, it Will be observed that my improved connection between the picker and stick and the lug strap, allows the lug strap to be substantially vertically adjusted to any desired position. Owing to the fact that the lug strap is likewise longitudinally adjustable, the distance of the throw of the picker stick may be varied at the will of the operator. This connection also reduces to a minimum the wear on the picker stick and the lug strap.

Although I have illustrated in the accompanying drawings a certain type of lug strap such as is commonly used on this type of looms, however, any lug strap that has one end provided with a yoke surrounding the picker stick may be used.

From the foregoing description of the construction and operation of my new and improved looin attachment, the manner of applying the same to use and the operation thereof will be readily understood, and it will be seen that I have provided a simple and efiicient means for carrying out the objects of the invention.

I claim 1. A strap holder for picker sticks comprising a coupling member having a spring hook at one end thereof, a picker stick connection for said member formed from a flat plate adapted to be secured to one side of the picker stick, oppositely bent angular upper and lower portions on said plate, the upper portion engaging opposite sides of the picker stick, a horizontally extending pivot bar positioned through the lower portion of said plate and adapted to receive the spring hook on the endof the coupling member, means for pivotally and detachably connecting the opposite end of said member to a lug strap, and said member being longitudinally adjustable.

2. A strap holder for picker'sticks comprising a coupling member having one end pivotally and detachably connected to a picker stick, a hinge member carrying a bar spaced therefrom secured to the end of a lug strap, a spring hook on the other end of the coupling member adapted to engage said bar to detachably and pivotally connect the coupling member and the lug strap, and said coupling member being longitudinally adjustable. c

3. A strap holder for picker sticks comprising a rod having one end pivotally and detachably connected to the picker stick, external screw threads on the opposite end of the rod, a flat strap having one end pivotally and detachably connected with a lug strap, a lateral extension on the other end of said strap, said extension having an opening through which the threaded end of the rod is adapted to be slidab-ly positioned, and locking nuts on the rod on opposite sides of the extension, whereby the strap may be locked at various longitudinally adjusted positions on said rod.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses- CHARLES FABER.-
