TAKE-UP MECHANISM FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 416,347, dated December 3, 1889.

' Application filed April 13, 1889. Serial No. 307,117. (No model.)

To all whom it may concern:

Be it known that I, CHARLES E. RUMSEY, of Homer, in the county of Cortland and State of New York, have invented a certain new and useful Improvement in Take-Up Mechanisms for Looms; and I do hereby declare the following to be afull, clear, and exact description of the same, reference being had to the accompanylng drawings, forming a part of this specification, and to the letters of reference marked thereon.

The present invention relates, generally, to devices for maintaining a constant and even tension on the fabric as it is formed and wound on the receiving-roller, even though the size of the roller is constantly in creased by the addition of new fabric. Such constant and even tension it has been found impracticable to maintain where the fabricis led directly from the reed to the roller and the feed maintained at an even rate until the roller is full by reason of the increase in the size of the roller, as before mentioned.

The mechanisms devised for overcoming the difficulty may be divided into two principal classes, one employing mechanism to vary the rate of feed of the winding-roller as the size of the same increases, and the other employing a roller or frame bearing (usually by gravity or spring pressure) against the fabric intermediate the reed and Winding-roller and serving to keep the tension even on the fabric as it is formed, the feed-roller being rotated to wind the fabric at predetermined intervals or when the tension-frame has reached the limit of its movement. To this latter class of take-ups or tension devices my inven tion has more particular reference, and especially to such as employ a weighted tensionframe resting on the fabric and which operates to throw the winding-roller into or out of operation at the proper. moments, or when said frame reaches the extremes of its movement, the object of the invention being to provide a simple and efficient mechanism for automatically throwing the windingroller into and out of operation at the proper moments, which will be positive and quick in its action, not liable tobe disarranged or get out of order, or permit the clutch or gears to slip as they are brought together, and consisting of few and simple parts.

To this end the invention consists in certain novel details of construction and combinations and arrangements of parts, to be hereinafter described, and pointed out particularly'in the claims at the end of this specification.

In the accompanying drawings, Figure 1 is a side elevation of a take-up mechanism constructed in accordance with my invention and applied to a loom, :such as is usually employed in Weaving wire-cloth. Fig. 2 is a similar View of the lower part of the lower frame with the weighted frame elevated. Fig. 3 is a top plan view of the catch and trip.

Similar let ers of reference refer to the same parts.

The loom-frame reed and swinging frame may be of any desired or preferred type, said parts, as shown in the drawings, consisting of the ordinary rectangular frame A, with the swinging frame 13 hung at the top, with the reed mounted thereon in the usual manner, as will be readily understood by those-skilled in the art, and as they form no part of my present invention these features will not be further described in detail.

Pivoted in the main frame, preferably be low the lay and reed mechanism, is a tensionframe 0 of sufficient weight to give therequisite tension to the fabric, and above this frame is journaled the winding-roller D for receiving the fabric E, which latter passes from the reed over the roller F on the frame, thence down under the roller G on the tension-frame, and then up around the windingroller. The driving-shaft H is journaled in the loom-frame, being driven from any suitable source of power, and bears at one end the bevel-gear h in position to gear with a similar gear 6 on the shaft 1, also journaled in said frame and gearing, with a gear on the :winding-drum for rotating the latter, such gearing preferably consisting of a worm L7 on the shaft, and a gear c on the drum engaging therewith. The gear 2 is preferably gagement .with the gear 7), whereby the winding-drum may be intcrmittingly rotated: but as is obvious, if desired, the gear II may be loosely mounted on the shaft 1 and be at all times in gear with wheel 71 a clutch member, such as 7s, Fig. 2, connected to the shaft by a spline and groove being employed in this instance to make the requsite connection between the shaft I and gear i.

A shifting bar or rod K, working in a groove in the hub of the wheel '1' or clutch member 7c, as the case may be, is employed to shift the same, motion being imparted to said shiftingbar at the proper times in the following manner: A latch or lever L is pivotally mounted on the loonrframe and connected at one end to the shifting-bar K by red Z, and connected to the opposite end of the latch is a rod M, having coil-springs m n thereon, with a nut n at the top for adjusting the tension of the springs. A lever N, also pivoted to the loomframe, is provided at one end with a collar or eye m, surrounding the rod M intermediate the springs, as shown in Fig. 1, being thus held from motion in either direction by spring pressure. The opposite end of said lever is provided with an eye, through which a rod 0 passes, said rod being connected, preferably, atone end only to the tension-frame and provided at the bottom with a shoulder 0, for elevating the forward end of the lever and depressing the latch through the medium of the spring m when the tension-frame is elevated, thus uncoupling the clutch and throwing the winding-drn 111 out of connection with the driving-shaft and arresting its motion.

In order, now,-to keep the clutch out of cngagement and to insure its quick return at the proper moment, to prevent the slipping of the clutch or such liability of breaking the same as there would be in case the slow motion of the tension-frame were relied upon, I provide a catch for the latch L,which holds the ame depressed until the proper momcnt,whcn it is released and the cluteh-sections thrown together quickly by sprin g-pressure. The said catch consists, preferably, of a rod having cranked arms I and (Q, and an extension I on arm P, which latter constitutes the catch proper. The cranked rod is pivoted at the center 1) 011 the loom-frame, the arm Q extend- -ing under the tension-frame and the arm I in position to engage the latch L, as shown clearly in Fig. A spring It connects the end I" of the catch and far end of the latch, serving to hold the catch normally elevated and also to throw the clutch -sections into gear, as will be readily understood upon an inspection of Figs. 1 and 2; but in order to bring an additional pressure to bear the rod 0 is provided with a nut at the upper end, which, when the tension-frame is depressed, depresses the lever and compresses spring n, which, when the latch is released, materially assists in quickly elevating the same and throwing the clutch into gear, as just clescribed. It is obvious that eithcrof the springs may be employed independently, or that any spring for returning the latch may be employed independent of the lever.

From. the above the operation when the tension-frame reaches the lower limit of its movement will be readily understood, being as follows: Assuming the catch to be in the position of Fig. 2, when the tension-frame descends the spring a is compressed and the catch released by the engagement of the arm Q with the under side of said frame. The springs then assert themselves and throw the clntclrsections quick] y into gear, rotating the winding-roller and elevating the tensionframe until the latch is again depressed and the clutch thrown out of gear.

It is obvious that many of the details of construction may be modified and changed without departing from the spirit of my invention, so long as the principal elements the latchcontrolling the clutch and the catch to retain the latch in position, operated by the tension-frame to release the latch, with the means for causing the engagement of the latch and catch-are retained, and I do not, therefore, wish to be limited to the specific structure shown in the drawings.

Having thus described my invention, what I claim as new is 1. In a loom, the combination, with the driving-shaft and the winding-roller on which the fabric is wound, of atension-i'ramc supported by the fabric, roller operating mechanism driven by the shaft, a shiftingmechanism for connecting ordisconnccting the roller-operating mechanism to and from the shaft, a latch connected to said shifting mechanism for moving the same, and a catch for holding said latch, operated by the tension-frame to release the latch, substantially as described.
