LOOM-TEIVIPLE.

SPECIFICATION forming part of Letters Patent No. 775,775, dated November 22, 1904.

Application filed October 17,1903. Serial No. 177,414. (No model.)

To a whom, it may concern:

Be it known that I, ALFRED MEUNIER, a citizen of the United States, residing at Taunton, in the county of Bristol and State of Massachusetts, hav e invented certain new and useful Improvements in Loom-Temples, of which the following is a specification.

This invention relates to loom-temples, and has for its object to provide a simplified and practical construction for performing the usual functions of a loom-temple with a minimum wear of parts and without injury to the edge of the fabric engaged by the fabric-holding means or rolls.

To this end the invention contemplates a construction embodying a minimum number of parts which can be readily assembled an separated.

Furthermore, the object is to improve the. spring-mounting for the sliding temple-bar, so as to more efi'ectively position the spring,while at the same time guard against the throwing of oil on the fabric.

The invention also has in view an improvement in the fabric-holding rolls whereby a firm grip will be secured, while at the same time the possibility of damage, such as' is usually occasioned by the ordinarybur-rolls, is entirely obviated.

In connection withthe arrangement of the various parts of the temple the invention contemplates a novel buffer-finger attachment of an adjustable form and so positioned as to receive the stroke of the lay in direct line with the sliding temple-bar, whereby the wear of parts incident to the said stroke is reduced to a minimum.

With these and many other objects in view, which will more readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination, and arrangement of parts, which will be hereinafter more fully described, illustrated, and claimed.

The essential features of the invention involved in the carrying out of the objects above indicated are necessarily susceptible to structural modification without departing from the scope of the invention; but a preferred embodiment of the improvements is shown of the accompanying drawings, in which- Figure 1 is a plan view of the loom-temple embodied in the present invention and shown applied to an ordinary wooden breast-beam. Fig. 2 is a sectional view on the line 2 2 of Fig. 1, showing a temple applied to an angleiron breast-beam. Fig. 3 is a perspective view of the temple, showing the cover-plate removed to expose the spring-mounting and spring-housing.

Like reference-numerals designate corresponding parts in the several figures in the drawings.

In carrying out the invention the same is confined particularly to that type of roll-temples wherein the temple-bar has associated therewith an actuating-spring to provide, in connection with the contact or the stroke of the lay, a sliding or reciprocating movement for the bar.

As shown in the drawings, the temple-bar is designated by the numeral 1 and essentially consists of a substantially straight bar throughout, which is provided at its active end with a dipped portion 2, which may be properly termed the roll-carrier, for supporting the series of horiZontally-alined laterally-projecting fabric-holding rolls 3, each of which is loosely journaled on a stationary supporting-axle 4:, secured fast at its inner end to one side of the temple-bar and provided at its outer end with a retaining-head 5 for maintaining the rollthereon in position.

A distinct feature of the present invention resideslin the employment of a plurality of horizontal rolls 3 in parallel side-by-side relation, there being in the series three or more of such rolls to provide extended grippingsurface for firmly gripping or holding the edge of the fabric, which is threaded through the series of rolls by being passed alternately over and under the adjacent rolls, as is plainly shown in Fig. 2 of the drawings. Also an important partof the invention resides in providing each of the rolls'with a roughened gripping-surface provided by a coating or cover of any rough substancesuch as emery, crushed stone, or the like emd there is a tapering interval between the adjacent rolls to insure sufficient freedom for the frictionallygripped fabric and also to facilitate the insertion between and disengagement from the rolls. This roughened gripping-surface for the individual fabric-holding rolls is entirely different from the ordinary burred roll commonly employed in loom-temples, and consisting of rolls having needle-points or burs projecting therefrom. These burs or points in the ordinary temples stick through the fabric, and if the latter is light the longitudinal threads are displaced. Furthermore, in this construction if the burs or points become bent, as they frequently do, the same pick up the cross-thread, and when the filling is nearly run out there is always more friction prod need by these burs or needle-points, with the consequence of causing more drag on the selvage. When this drag occurs, if the bur or needlepoint happens to grip the fabric too firmly the filling breaks near the selvage and produces a hole. Many other objections, such as the leaving of marks, &c., exist to the use of the ordinary bur-rolls, whereas the present invention obviates these objections.

The supported end of the temple-bar 1 has a sliding movement longitudinally in the open slideway 6 of the guide-box 7. This guidebox 7 is of a U shape in cross-section and is provided with an open top, which is designed to be covered by the adjustable cover-plate 8, extending the full length of the box and provided at the longitudinal edges thereof with the short pendent retaining-flanges 9, overlapping the sides of the guide box 7 and serving to prevent lateral displacement of the said cover-plate. .The said coverplate is firmly yet detachably held over the open top of the guide-box through the medium of a fastening-bolt 10, the head of which is adjustably engaged in a longitudinally-disposed slot 11, provided in the base of the box 7. At its fastened end the adjustable cover-plate is further provided with an integral abutmentblock 12, projecting into the housing-slot 13, formed longitudinally in the sliding templebar 1. This housing-slot accommodates therein an actuating-spring 14, one end of which bears against one end of the slot and the other end of which has a bearing upon the stationary abutment-block 12.

The guide-box 7 constitutes a part of what may be properly termed a holder-bracket 16 for the temple bar, and which holderbracket comprises the said box 7 and the longitudinal slotted attaching-plate 17, projecting integrally and laterally from the box.

The longitudinal slotted attaching-plate 17 is adapted to be adjustably fastened upon the breast-beam B of the loom through the medium of a securing-bolt or equivalent device 18. I/Vhere the temple is applied to a Wooden beam,

as shown in Fig. 1, a metallic wear-plate 19 is secured upon the surface of the beam to take up the wear incident to the mounting of the temple; but this plate is not necessary where an iron beam is used in the loom, as shown in Fig. 2.

At an intermediate point the sliding templebar 1 is provided with a longitudinally-disposed slot 20, which adjustably receives the fastening-bolt 21 for the pendent buffer-finger 22, having a supporting-flange 23 at its upper end for the reception of the bolt 21. The buffer-finger 22 is designed to receive the blow of the lay; but by reason of lying wholly within the plane of the temple-bar the stroke of the lay is received in direct line with the bar, thus reducing the wear and friction of parts to a minimum.

Various changes in the form, proportion, and minor details of construction may be resorted to without departing from the spirit of the invention or sacrificing any of the advantages thereof.

Having thus described the invention, What is claimed, and desired to be secured by Letters Patent, is

1. In a loom-temple, a holder having a guidebox, a sliding temple-bar working in the box and provided at one end with a series of laterally-projecting stationary supporting-axles arranged in the same horizontal plane, burless fabric-holding rolls loosely journaled on said axles and provided with roughened peripheral gripping-surfaces, said rolls being closely arranged side by side with tapering intervals therebetween, and an actuating-spring arranged within the box and engaging the temple-bar.

2. In a loom-temple, a holder-bracket designed to be attached to the breast-beam and having an open guide-box, a sliding templebar carrying fabric-holding rolls and provided with a spring-housing slot, an actuating-spring arranged in the slot of the temple-bar, and a detachable cover-plate for the guide-box.

3. In a loom-temple,the holder-bracket having an open guide-box and a slotted attachingplate projecting laterally from the box, a sliding temple-bar workingin the box and carrying fabric-holding rolls, said bar being provided with a longitudinally-disposed housingslot, a spring arranged in said slot, and a detachable cover-plate fitted over the open side of the guide-box and having a bolt connection with the base thereof, said cover-plate being provided with a rigid abutment-block engaged by one end of the spring.

In testimony whereof I aflixmy signature in presence of two witnesses.

ALFRED MEUNIER.
