UNITED STATES PATENT OFFICE SAMUEL Bo'oRN, oE LOWELL, MASSACHUSETTS.

IMPROVEMENT lN CUSHIONS FOR SHUTTLE-BOXES..

Specification forming part of Letters Patent No. 35,808, dated July 8, 1862.-

To all whom, it may concern.-

Beit known that I, SAMUEL BOORN, of Lowell, in the county of Middlesex andH State of Massachusetts, have invented a new and useful Improvement in Looms; and I do hereby declare the same to be fully described in the following specication, and represented inthe accompanying drawings, of which-- Figure 1 denotes a top view of a metallic case provided with my invention, the same being applied to a race-rod of a loom. Fig. 2 is a horizontal and longitudinal section of the same.

The nature 'of my invention consists in au improved cushion to be' applied to a metallic case, which is to be placed upon each end of the race-rod A of a loom, in order to receive the blows of the picker or picker-staff, either in its extreme forward or rearward movements, and thereby prevent the injury usually arising to the picker or its staff when cstopped by a hard unyielding material. Y

The object of my invention is threefold: lirst, to prevent the violent concussion and wear ot' the picker; second, to greatly diminish the noise incident to the usual action ol'` the picker and picker-stati', and third, to preserve the cushion in its normal condition.

In carrying out my invention I employ one Vo r more disks,a,or other propershaped pieces a metallic case, B, and conne them together and in the said case by means of a band or strap, d, passing around them in manner as shown in Eig. 2. A cushion and its case, constructed as above set forth and as shown in the drawings, I apply to each end of the raceway and on the race-rod of the shuttle-box thereof, it being confined to the rod A by screws, or in any other suitable manner.

I have found by experience of more than a year that the combination of leather, indiaw rubber, and hair, arranged as above set forth, mutually protect each other against the violent shocks of the picker or pickerstaif, while at the same time they preserve such picker or staff from injury. A cushion, if made entirely of leather, soon becomes indurated and loses its elasticity. One of vulcanized rubber is liable soon to become softened or injured by the oil on the picker-rod, and besides, when inclosed in a metallic socket-,it is likely to Soon become so driven and compacted therein as to have its elasticity seriously impaired,if notentirely destroyed. By placing in the rear of the caoutchouc block a mass of .curled hair, and in front of it a cap 0r covering of leather, I have found by experience that the caoutchouc is preserved intact, or will not only maintain its elasticity, but will be protected from thc softening and injurious effects ofthe oil.

I claim- My improved cushion, as made of a combination of leather, indiarubber, and curled hair, arranged within a metallic case, B, in manner and for the purpose set forth.

SAMUEL BOORN.
