AUXILIARY BOX-MOTION FOR LOOMS.

SEFECIFICATION forming part of Letters Patent No. 669,824. dated March 12, 1901. Application filed May 25,1900. Serial No. 17,917. .hlo models To will whmn it may concern:

Be it known that I, JOHN EATON, a citizen of the United States, residing at 159 Jasper street,city of Paterson, county of Passaic,and State of New Jersey, have invented certain new and useful Improvements in Auxiliary Box-Motions for Looms; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to box-looms, and it has reference particu larly to that form of loom of this nature in which the several shuttleboxes are brought into operative position relatively to the shuttle-races on the batten by corresponding levers acting through a suitable intermediate mechanism. As an illustration of the kind of loom referred to attention is directed to that shown in United States Letters Patent No. 572,251, of December 1, 1896.

The object of my invention is to provide an auxiliary mechanism for use in connection with looms of the kind referred t0'i. 6, those having their box-motion dependent upon the action of a series of levers, whereby, a jacquard apparatus being employed as an ad junct of the loom, said jacquard apparatus may be brought into service to control said levers.

Referring to the accompanying drawings, wherein corresponding letters of reference indicate like parts, Figure 1 shows the upper portion of a loom-frame with my improved apparatus mounted thereon. in rear elevation of my invention, certain parts being removed. Fig. 3 is a top plan view of said invention; and Fig. 4: is a view in side elevation of a loom substantially like that referred to in the patent above mentioned and of my apparatusinounted on said loom, showing the connections between said apparatus and the parts of the loom controlled thereby.

Upon the arch a of the loom-frame b is secured, as by a bolt 0, a bracket d, said bracket Fig. 2 is a view having a project-ion e, which extends between the flangesfof the arch and fits therein so as to steady said bracket. Said bracket comprises a vertically-slotted plate or grid g and, extending rearwardly from said plate, an upwardly-curved arm h. The upperend of said arm 71 carries a shaft i, disposed horizontally and parallel to the plate g. On said shaft are fulcrumed three-armed levers j, the corresponding arms 7c of said levers projecting through the slots Z of the plate or gird g. To the arms m of the levers are connected the cords n for moving said levers in one direction. To the arms 0 of said levers are secured at one end flexible connections 10, the other ends of said flexible connections being secured to the arms q of bell-crank levers r, which are fulcru med in a bracket 8, also secured to the arch of the frame in any desired manner, as by a bolt 25. To the other arms a of these last-named levers are secured flexible connections 1;.

Upon pins to on the plate or grid are fulcrumed pawls or latches 00, said pawls being connected at one end by springs y to studs 2, extending from said plate. To the same ends of the pawls are connected cords 91'. Each pawl is arranged to be normally held by its spring with its free end opposite one of the slots Z in the plate or grid. I prefer to accomplish this, as shown in the drawings, by forming the ribs between the slots Z of the plate with longitudinal projections ct, the alternate projections being formed on one side of the plate, while the others are formed on the other side thereof, and by so arranging the latches or pawls in pairs that each pawl can normally abut against one of said projections as a stop. Thus when the arms 70 of the levers m are below the series of pawls they will be by them held there and cannot be elevated until the pawls have been moved.

It will be understood, of course, that the flexible connections 1) are adapted to be se cured at their free ends to levers b, which are in turn connected by flexible connections 0 to the pawls d, involved in the intermediate mechanism whereby the shuttle-boxes are operated,said mechanism being shown in Fig. 4. A description thereof is embodied in the patent referred to and is therefore unnecessary herein.

The cords n and n are adapted tobe connected to certain of the hooks of a jacquard apparatus which are set aside for this purpose, the cards being provided, of course, with extra perforations for accommodating the needles which control said hooks.

In operation, whenever a certain box is called, as the knife of the jacquard machine from which the mechanism is operated rises and lifts the hook to which the arm mof one of said levers is connected the arm 70 of said lever will move downwardly, forcing back the free end of the pawl 03 against the tension of its spring until it has passed the same, whereupon said pawl will snap back, thereby preventing the return of the lever. The return of the lever will not be efiected until another hook has been elevated by the knife of the jacquard, such hook being connected with the pawl 00 through the medium of one of the cords n. Thus as said pawl is actuated the lever j will be released, and by the action of gravity afiecting the corresponding levers r and the pawl or other corresponding part of the intermediate mechanism mentioned said leverj will be returned to its initial position.

Having thus fully described my invention,

What I claim as new, and desire to secure by Letters Patent, is

The combination, in a loom box-motion mechanism adapted for use auxiliarly with a jacquard mechanism, of a suitable frame, a slotted plate or grid and a shaft comprised in said frame, levers fulcrumed on said shaft and projecting into the slots of said plate or grid and adapted to be operatively connected with the boxes to actuate the same, and latches fulcrumed on said plate or grid, each latch being normally held in the path of movement of a corresponding lever, substantially as described. V p

In testimony that I claim the foregoing I have hereunto set my hand this 7th day of May, 1900.

JOHN EATON.
