BUFFER CHECK FOR LOOM PICKERS.

Application fi1ed August 1, 1922.

To all whom t may concern Be it known that I, JOSEPH J. KURTZ, a citizen of the United States, and a resident of Shamokin, in the county of Northumberland and State of Pennsylvania, have invented new and useful Improvements in Buffer Checks for Loom Pickers, of which the following is a full, clear, and exact description.

ln the operation of looms theshuttle is thrown back and forth from one shuttle box to another, and is arrested at each end of its travel by a devicenamed the picker, which slides on one or more rods and has a portion projecting into the path of the shuttle.

The picker acts as a buffer for the shuttle by affording a yielding resistance thereto; and also, of course, it reverses the direction of travel of the shuttle. Various devices have been suggested and tried as bufferchecks for the picker; but because of the innumerable and rapid stresses to which the buffer is subjected, all of the devices previously suggested have lacked durability. Leather has produced the best results, but it is well known that the life of even the leather buffers is extremely short.

The object. of the present invention is therefore to provide a buffer-check for loomV pickers which will not only be highly resilient but also will possess great durability in operation; and which will be inexpensive in manufacture.

Vith the foregoing and other objects in view I will now describe in detail the preferred form of my invention, reference being had to the accompanying drawings; in which,

Figure l is a plan view of the apparatus; the shuttle box and shuttle being shown in dotted lines.

Figure 2 is a front elevation of the apparatus; the shuttle box and shuttle being removed.

Figure 3 is a perspective view of the appara-tus; parts thereof being broken away.

Figure 4 is a plan View of a portion of the picker; the remainder thereof being shown in dotted outline; and

Figure 5 is a detail sectional view of the recoil member and the buffer mounted therein.

Referring to the drawings more in detail, numeral l indicates the shuttle box in which the shuttle 2 is reciprocatede A picker rod,

is indicated by numeral 8, and slidably mounted on said rod is the standard or conventional picker 4. A. picker-stick 5 enters a slot in the picker in the usual manner, 00 said picker-stick being provided with any ordinary means not shown) for moving it and through it the picker, in such manner as to shoot the shuttle back and forth. The foregoing structure has been only bri elly described as it is old and well known in the art and constitutes no part of thepresent invention.

It is also old to provide a buffer at each end of the path of the picker to afford a yielding resistance to the shuttle, and to reverse the direction of travel thereof. My invention relates to improvements in this buffer.

Recoil members are indicated by numerals 6, 6. These recoil members are preferably made of solid rubber, though they may be made of other material such as leather, and are provided with two holes whereby they may be mounted on the picker-rod 3, one of the holes being indicated by numeral 7. Thermanner in which the recoil member is mounted on the rod is obvious from an inspection of the drawings, the arrangement being such that the inner portion of the recoil member is free to move back and forth on the picker rod, to take up the recoil as the picker strikes and to reverse the direction of movement thereof.

One of the serious disadvantages of the buffer-checks previously known, is that because of the wear and tear they have only an extremely short life. In accordance with my invention I out a portion indicated by numeral S, from the picker and insert the leg 9 thereof into the hole 7 of the recoil member 6. The recoil member 6 being preferably made of rubber, no securing` means need be provided, the resiliency of the rubber being suiiicient to maintain the element in operative position. The cut-out portion 8 of the picker may be termed a buffer, and comprises, in addition to the leg 9, a shoulder 10 which projects beyond the surface of the recoil member and receives the blows from the picker.

A buffer-check constructed in this manner possesses an unusually high degree of durability, and after long use if the buffer element has worn down considerably it is only necessary to remove the buffer and insert another in the hole 7 of the recoil member G. It should bementioned here that the cost of the buffer elements will be nil, for they are merely cut out of the discarded pickers. These pickers are usually made oit eowhide or similar' material and as they are rapidly Worn on account of engagement with the picker, their life is relatively short. rl`he prior practice has been to destroy the pickers when they became Worn out, but under the presennt invention when a picker is discarded the buffer portion will be out out and retained for use in connection with the recoil member, in the manner previously described.

It may also be noted that in accordance with my invention the picker will strike against a buffer made of the same material, for the butler is merely a portion of a discarded picker.

It Will be understood, of course, that this buffer is adapted to use with any type of loom, and may be used at both ends, as illustrated, or at one end only, in some types of looms. v

From the 'foregoing description it will be obvious that I have invented a. buffer-check for loom-pickers Which not only possesses durability to an 'unusually high degree, but also one 1n which the buffer element may be renewed-Without any additional expense.

4ln accordance with the patent statutes, I have described What l noiv believe to he the 'best embodiment of the invention, but I do not `Wish "o be understood thereby as limitfing'myself or the scope of the invention, as

many changes and modifications may be made Without departing` from the spirit ot the invention; all such I aim to include in' the scope of the appended claims.

Vhat l claim as newv and desire to secure by Letters Patent is:

l. A buffer-check Afor loom-pickers, including; a rubber recoil member, and a butler mounted in said rubber recoil member, the resiliency of the recoil member constituting the retaining means for the buffer.

2, A, butter-check tor loom-pickers, including a recoil member, and a builer associated with the recoil member, said buffer including a hollenv legl member cut from a portion of a standard picker, said leg member adapted to be attached to the recoil member.

3. ln a buffer-check for loom-pickers, a butter, said butler constituting a cut out portion of a standard picker and comprising a and a shoulder and a recoil member, said leg adapted to be attached to the recoil member.

et. A buffer for use in connection with loom-pickers, said buffer comprising a hollow leg and a shoulder, said leg adapted to be attached to a recoil member, the crosssectional shape ,o't the butter being sub stantially the same as the cross-sectional shape or a standard picker.
