Patented Nov. 8, 1921 Application filed January 14, 1921. Serial No. 437,295.

To all whom may concern:

Be it known that I, ABNER JUDSON LURRY,

a citizen ofthe .United States, residing at Baton Rouge, in the parish of East Baton Rouge and State of Louisiana, have inventing, lacing, or darning of fabric known as ress cloth, which is a kind of material used or the wrapping of oleaginous products while undergoing compression in hydraulic presses, to theaction of which such products are subjected for the the oil therefrom.

This press cloth becomes torn and rent. in

places which renders it unfit forefi'ective use, and which makes it difficult to handle involving waste of time and labor.

It is an object ofthe invention, therefore, to provide an improved machine in which this press cloth may be repaired at the m ll quickly and at a minimum of ex ense, while providin for the convenience o the opera- Q tor and For his personal comfort re airing operation.

b e inventionmoreover' aims to provide a machine for carrying out the above ob jects, which will be simple in construction and inexpensive to manufacture, and which will be adjustable with respect to a seat provided for the operator.

With the foregoing and other objects in view, the invention will be more fully described hereinafter, and will be more particularly pointed out in the claims appended hereto. 0

Fig.8 is a view in elevation of one of the movable jaw holders; and

Fig. 9 is an elevational view of one of the fixed 'aws. Re 81'11I1 more particularly to the drawings, accor ing to the invention I provide a support which preferably a carpenters saw bench made up of supporting legs 1 and a pair of beams 2 and fixed to the legs and extending in a substantially horizontal direction with a slot 4 left between them. A seat '5 for the operator is either fixedly or adj ustably secured upon the support, which is constructed preferably near one end thereof so as to leave ample space on the support for the clamping device, which is of a duplex character.

The clamping device consists of a pair of heads 5 and 6 made, as shown in F igs. 3 and 4, of a substantially diamond shape in 916- vation and provided with legs 7 adapted to receive bolts 8 which extend through the slot 4 of the support and are adjustable therein. Clamping nuts 9 onthe ends of the bolts are adapted to secure the device in the adjusted position on the support In this way the clamping device may be moved toward or from the seat 5 to accommodate the operator. A trough beam 10 having ,diveigent side walls is mounted upon the central and uppermost portions of tlie'heads 5 and 6 and extends between them lying substantially parallel with the beams 2 and of the support. This trough beam may be secured to r the heads 5 and 6 in any suitable manner, bolts 11 being indicated as this method of fastening renders it possible to disassemble movable jaws which clamp it securely in place andprevent the cloth at the opposite sides of the rent from falling away. The fixed jaws are indicated at 13 and let, and they are supported in convergent relation at opposite, sides of the saddle. One of the jaws 13 is shown more particularly in" Figs.

- 5 and 9, where these jaws are illustrated'to be provided with supporting arms 15 and 16 formed with angularly disposed bearing bosses 17 and 18 for cooperating with similar complemental bearing bosses 19 and 20 carried by the opposite heads .5 and 6.

The bearings thus-provided are adapted to receive rock shafts-21 and 22 which carry collars 23 secured thereon by set'screws 2d 30, one such jaw beingshown in Figs. 6 and 7. The upper face of each jaw is provided with corrugations31 and with bolt holes 32 near its longitudinal central portion. Re-

' cesses 33 are cut in the sides ofthe movable jaw also preferably near the longitudinal center thereof, the under sides of the jaw being cut away as indicated at 34. The movable jaw 3O is adaptedto be removably received in .a holder 35 shown more particu larly in Fig. 8 provided with upstanding lugs 36 slidingly receivable in the recesses 33 in the jaw and having bolt holes 37 in which to receive the fastenings which pass through the bolt holes 32 of the jaw.

A slot 38 is made in the web 39 of the holder to receive the shaft 22and to permit the holder to slide at right angles'to theaxis of the shaft whil'e' permitting theshaft to rotate freely in .the holder. An. eccentric strap 40 projects outwardly from the holder and forms therewith a recess in which the eccentric is housed. As .more particularly shown in Fig. 4, the eccentrics 4E1 and 42 operate within the housing thus formed and act to shift the movable jaws 29 and 30 toward and awayfrom the fixed jaws let and 13 respectively. 1

A set collar 43 on each of theshafts is fitted up against. the eccentric and holds the same in the housing provided by the holder.

A- second set-collar 44 on the opposite side of each shaft provides an abutment against 'which. onezend of aflcoilspring a5 seats, the "otheri-e nrl' pressing against a washer 4'6 and washerjagainst the'holder so as .to resist "tami 'orthe shaftsiwhich' results in the "shafts being thus yieldingly" held in adjusted position. These parts 44-, i5 and 4:6 are also for the purpose of causing the two ends of the movable jaw to be equally spaced from the stationary jaw, when open, and on the other-hand to permit the movable jaw to adjust itself against any unevenness of the material when under pressure.

Plates a7 and 48 are secured to the lower sides of the arms 1:) and 16 of the stationary jaws and are spaced from the jaws at their upper ends in order to provide slots all) shown in Figs. 4.- and 9 in which to permit passage of the cloth.

In the use of the device, the operator seats himself upon the seat 5 with one leg to each side of the beams 2 and 3. He then draws the clamping device toward him until it is at a convenient position at which time the nuts 9 may be tightened to secure it in place. Opposite ends of the cloth to be darned or laced are threaded through the spaces be tween the two sets of clamping jaws, while these jaws are open and the ends are brought together sul'istantially upon the middle high portion of the wooden saddle 12.

The cloth is then clamped within the aws which will hold it in proper position. An awl. is used to punch holes through the cloth at opposite sides of the meeting edges and a needle with thread is inserted in the oppositedirection through the holes made by the awl, preferably before the awl withdrawn so as to facilitate this operation.

The machine affords the operator the opportunity to firmly hold the work in. a position that will enable him to adjust himself to the work in the fashion of a shoemaker with the work strapped to his knee, or the tailor pinning it to his pants near the knee and to this end the arrangement and disposition relatively of the seat and the clamping device is such that the work will it as closely as possible in the lap of the operator, and it will permit the operator to move his legs closely as possible together and about the machine so as to prevent fatigue and, at the same time. to allow the cloth ends to pass freely outside of the legs.

' The movable jaws 29 and 30 are opened by swinging the handles 26 and 28 over toward one another until they strike the opposite shafts or adjacent parts. the handles then being crossed. After the material is placed in the device. the levers are swung in an opposite direction, which moves the eccentric to the position shown at theleft in Fig. t thereby clamping the material between the jaws.

The device is useful, not only in securing pieces of cloth together, but also in darning holes-in cloth and securing rents of every description.

It is obvious that various changes and modifications may be made inthe'details of construction and design of the above'sp'ecificall y described embodiment of this invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claims.
