F. J. WILSON LOOM TEMPLE April 5, 193s.

Filed Dec. 19, 1935 2 Sheets-Sheet 2 Patented Apr. 5, 1938 UNITED STATES PATENT OFFICE LOOM TEMPLE of Rhode Island Application December 19, 1935, Serial No. 55,235

7 Claims.

This invention relates to a loom temple for holding woven fabric taut in a widewise direction in the loom; and has for one of its objects the provision of spring pressure in such a temple arranged that there may be a balancing of the pressure between the end portions of the fabric gripping means for holding the same taut.

Another object of the invention is the provision of an arrangement by which uniform pressure across the engaging surfaces may be quickly acquired by an adjustment of the parts.

Another object of the invention is the 'provision of resilient means which may be easily and quickly adjusted to provide different desired pressures and either the same or different at opposite ends of the fabric engaging means.

Another object of the invention is an arrangement by which different pressures may be had for different fabrics, whereby a greater tension may be used for the heavier fabrics and a lighter tension for the lighter Weight fabrics, Without changing or interchanging any of the parts.

Another object of the invention is the provision of a means whereby the resilient pressure may be distributed against the member which contacts the upper surface of the cloth so that an even pressure along the surface may be obtained.

Another object of the invention is the provision of a spring which will act upon the member engaging the upper surface of the fabric from directly above this member so as to force the same downwardly from this superimposed position in substantially the direction it would travel by gravity.

With these and other objects in View, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the use of loom temples, it is frequently desirable that different pressures be had upon different fabrics, and also that a balanced pres- 5 sure may be had so that the pressure will be uniform along the length of the presser member whereby a very firm grip may be established; and in order that these results may be accomplished, I have provided in a three-roll temple a 10 hanger for supporting and mounting the upper roll, the same being guided towards the lower roll in a plane passing substantially between the rolls so that when the cloth is engaged it will be disposed in a sinuous path, and I have forced this l5 carriage with the upper roll downwardly towards th-e lower roll by a pair of springs which are disposed in alignment with each other and also substantially in the plane of movement of the hanger so as to act directly from above the roll in forcing it downwardly towards the lower roll; and the following is a more detailed description of he present embodiment of this invention, illustrating the preferred means by which these advantageous results may be accomplished:

With reference to the drawings, l designates generally the base portion of the loom temple with an arm Il extending to the bracket l2 for securing the temple in position.

rIhis base is cast with recessed portions I5 and 30 I6 for the reception of the rolls Il and i8, which are mounted on the axles I9 and 20 extending into bearing supports 2| in one end wall 22 and similar bearing supports 23 in the end wall 24 at the other end. The axles threadingly engage one of said supports and are provided with a slotted end 2l for easy rotation. These rolls are thus mounted in spaced relation and provide spaced engaging surfaces for the traveling fabric or web 25 which passes throughthe temple. The surfaces of the rolls are grooved as at 25 in a known manner to better grip the fabric.

Mounted upon the base there is a cap member designated generally 3G, and shown in perspective in Figure 7. This cap member has a tongue portion 3| to fit within a groove 32 in the base, while an opening 33 receives a bolt 34 which may -be threaded into the base as at 35 to securely bind the cap member in superimposed relation over and spaced from the base. The opposite edges 36 and 31 of the cap are suitably rounded to engage the cloth and with the rolls will dispose the fabric web in a more or less sinuous path depending upon the thickness of the cloth.

Within the cap 30 there is mounted a hanger 40 which may move vertically in the guideways 4l and 42 between the opposite side walls 43 and 44 at one end and 45 and 46 at the other end. This hanger is provided with depending portions 4l, 48 at its opposite ends, which provide bearings 49, for a readily removable spindle 5l upon which the upper roll 52 is rotatably mounted. This spindle is threaded as at 53 which engages the thread in the opening 50 to hold the same in position. An enlarged slotted head 54 is provided at the end of the spindle for manipulation by a screw driver for interchanges of upper rolls. A bar 56 extends laterally across the hanger 40 and beyond the sides thereof to engage the abutments 51 on the opposite sides of the guide portion 4l, while a bar 58 extends across the hanger at the opposite end for engaging the abutment 59 to support this end of the hanger against dropping from the cap.

The stops 56 and 58 are normally positioned well above their abutments 51 and 59 and the hanger is forced downwardly by two leaf springs 69 and 6I which are convex on their upper surface and concave on their lower surface providing spaced portions 62 and 63, 64 and 65 which engage at aligned points along the top surface of the hanger 4D so that when pressure is applied to the upper side of the spring at a point substantially half Way between the points of contact, the springs will be forced downwardly against the hanger while in turn forcing the roll which it supports downwardly in a plane substantially between the rolls Il and I8 so as to cause any fabric passing between these rolls to be iirmly gripped thereby. In this manner, the pressure is located in sub stantially the direction or plane of the path of movement of the roll and is generally directly above it.

The threaded member 66 engages the upper portion of the springs and Bl and has a slot in its head 61 so that it may be threaded downwardly through the threaded opening 68 in the bridging portions 69 and 10 of the cap to adjust the pressure upon the spring to the desired amount, which pressure having been obtained the hexagonal lock nut 'l2 is forced against the surface 13 of the bridge to hold this threaded member 66 in desired position for adjustment.

In order to prevent the springs from longitudinal movement or slipping from position, a screw 14 having a head 15 passes through an opening in the spring and into the pressure member 66 so as to hold the spring in desired position in the temple. This threaded screw 14 will not be caused to bind the spring against the bottom of the threaded member 66 but rather will permit rotation of the threaded member 66 without twisting the spring or turning the spring with it, by reason of a swivel arrangement.

By the construction provided, I may adjust the springs 60 and 6I so that they have the same amount of tension or they may be adjusted to have different amounts of tension, depending upon the objects desired to be accomplished. When set in their adjusted position the springs remain set at a fixed pressure until a change in the character of the fabric is made or a diierent pressure is desired. Thus, it is a simple matter to obtain the desired pressure adjustment after the temple is in position in the loom and after the fabric has been inserted through the rolls by a proper turning of the threaded members 66 so that it becomes unnecessary to take olf the cap for the preliminary insertion of the fabric therein at the initial setting up of the loom and placing the fabric in the desired position to determine the relation of upper tensioning roll thereto.

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.
