WARPING AND BEAMING MACHINE.

SPECIFICATION forming part of Letters Patent No. 325,284, dated September 1, 1885.

Application filed July 30, 1883. (No model.)

To all whom, it may concern:

Be it known that we, HERMAN F. STRAW and James D. BUTLER, both of Manchester,county of Hillsborough, State of New Hampshire, have invented an Improvement in Varping and Beaming Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention relates more especially to that part of a warping and beaming machine which is employed to form a chain-lease.

The apparatus herein shown and devised by us is adapted to be incorporated with or attached to awarping-machine to automatically separate each alternate thread in the warp from its adjacent thread, thus forming a shed through which to pass a string orlease-thread over and under adjacent warpthreads from side to side of the separated sheet of warps.

Figure 1 is a side elevation of a sufficient portion of a warping-machine with our improvements added to enable one conversant with that class of machinery to understand our invention. Fig. 2 is a plan or top view thereof, partially broken out to economize space on the drawings, the said figure having added to it two drop-rollers of usual. construc tion, one at each side of the measuring-roller. Fig. 3 is a detail, showingapart of the warpholding comb having forked dents with some warp-threads in and some between the dents, thus supporting them in different planes. Fig. 4 shows a lease, and Figs. 5 and 6 sectional details of the crank and stop for it on the line 00 as, Fig. 2, the said figures showing the crank in its extreme positions rather than in the full line position of Fig. 2, the handwheel being, however, omitted.

The warp-supporting roller a, the measuring'roller m, and the two drop-rollers n a herein shown are and may be as common to the class of machines referred to in United States Patent No. 137,605, or 154,466, or 266,331, and the drop-wires c, pivoted at 0, may be considered to be substantially such as shown in United States Patent N0. 108,856 or 257,133, so need not be herein further described, as our invention has nothing to do with means for stopping the machine on the breaking of a thread,

In our invention, as herein shown, we attach to a suitable frame-work, A, supposed to be common to warping-machines, a bracket,

a having at its upper end a bearing, a, to receive a short shaft, a, having a double-shouldered disk, at, provided with a crank-pin, b, to receive a connectingrod, b the other end of which is placed over a pin, b, of an arm, b, on the shaft b having suitable bearings in a bracket, I), attached to the frame A, as herein shown, bysuitable bolts, 4, one of which is shown at Fig. 1.

The shaft b has adj ustably attached to it two lifters, I), which control the up and down movement of the warp-separating rod h,which, placed between and separating the alternate threads cf of the sheet of warp, has its journals h supported upon the inclined or curved rod rest or guide h, shown as forming part of the bracket 6, the upward movement of the said rod being checked by the projection h.

The comb or reed is composed of the series of dents d, forked at their upper ends and held and controlled by expanding springs of m substantially such as common to United States Patent No. 221,799, November 18, 1879, the said springs and the usual screw for adjusting them to vary the intervals between the dents being contained in a box or case, (Z, which, besides shielding the said parts from dirt, &c., also serves as a support for the dents above the said springs.

Instead of the particular expanding springs herein represented and contained in the said patent, we may employ any other well-known expanding devices.

The shaft b has two other arms, 0 which act against the under side of the box or case d of the comb or reed and lift the latter, the notches of the said dents or teeth (1 receiving the Warpthreadsc and serving to support the latter, as best shown in Fig. 3, while tak ing a lease, the forked dents then supporting the warp 6 above the top of the roller or support g while taking a lease. The dents or teeth (1 project upward through a slot in the box or case of usual construction.

The comb or reed box d, instead of being stationary, as usual, is fitted between guides (1* of the brackets or frame parts I), and is supported upon this bracket, except when the arms 1) are swung to raise the conib-box in the guides of the bracket.

The warp -threads, after leaving the supporting-roller 9, will pass to and be wound upon a beam operated preferably as in United States Patent 137,605 or 226,331, referred to. In the drawings the warp-threads are shown by full lines as in their normal position, and it will be assumed that each thread comes to the rollers a", m, a, and a from aspool held in a creel-frame of usual construction.

When a lease is to be formed in front of the dents, the disk or crank a? will be turned to bring its crank-pin 2) into the position de noted by dotted lines, Fig. 1, and full lines, Fig. 5, which will cause shaft b to be turned and the lifters b to lift the rod h into its highest dotted-line position, Fig. 1, lifting the warpthreads f which are between the forked dents into the dotted-line position f, the threads 6 then rising at very little between the dropwire a and roller as indicated by the dotted line 18, so thata shed is formed for the passage of the lease-forming thread let between the warp-threads e f, while thosef are upper most, and during the insertion of the leasethread the dents are held elevated, because the projection 16 of the disk a rests against a part of the bracket aflwhich serves as a stop, the crank-pin being then below its back center. After this the disk or crank a is turned in the opposite direction to place its erankpin b'in the position 12, Fig. 1, or below the center line in front, (see Fig. 6,) which. will so turn the shaft b as to place the lifters 25 into the dotted-line position immediately below their full-line position, and leave the rod h supported on the ear 15 of the rod-rest h, such movement of the said shaft 1) and its arms b lifting the comb or reed, so that the box d and forked dents or teeth d therein are lifted into the dotted-line position, Fig. 1, elevating the threads 0 into the position 6 Fig. 1, the threadsf then being as in their full-line position, thus making a second shed in the warpthreads, but at this time at the rear of the shed first formed and entered by the leasethread; but in the second shed the threads 6 are uppermost for the return therein of the lease-holding thread 14. (See Fig. 4.) WVhile the lease-thread is being passed through the second shed the opposite shoulder, 18, of the projection of the disk a rests against the opposite side of the bracket or stop a as in Fig. 6. The partial movement of the disk or crank a back to its intermediate position brings the warp-threads of back to their full-line position. Fig. at shows the two lease-forming threads 14 in the position they will occupy in the warp to keep the lease.

The shoulders 16 and 18 and the bracket a form a stop for the disk and crank-pin, and any other usual or suitable form of locking device may be employed instead to retain the crank-pin below its center at back and front or its extreme position.

The dents, forked or notched at their upper ends, are supported only at their lower ends;

yet, owing to the length of the slots therein, the warp-threads are not liable to escape; but in case of the breakage of a warpthread the latter when pierced may be quickly laid into the space to receive it.

The reed-box dand the separatingrod h rest when in their ordinary positions, the former .upon the bottom of the jaw in the bracket 1),

and the latter upon the car 15. The handwheel a is then near its middle position; but when this hand-wheel is turned in either direction either (1 or h is lifted. The weight of box at resists movement in one direction and that of rod h in the other, and they do not in any sense balance each other. since they do not act upon the arms of rock-shaft k at the same time.

The resistance to the turning of the hand wheel which the weight of box d or of rod It makes at first changes to an assistance when the crank-pin passes the dead-center and draws the shoulder 011 crank-disk against the stop on bracket a thus making a very reliable lock, and one simple equally in construction and in working. The very weight of box d or rod h secures them respectively in their highest positions.

If box d and rod h were all the time sup ported upon opposite arms of shaft 7L5, they would inpart balance each other, and the action would be much modified as to the locking.

We claim 1. The comb or reed having a series of forked dents, and the warp-supports fore and aft of said dents, combined with the warpsupporting rod adapted to be placed between the warp-threads to divide them into two sheets or layers, a rest or guide for said rod, and lifters for said rod, and means to operate them, substantially as described.

2. The comb or reed having a series of forked dents, means to lift said dents, and the warp-supports fore and aft of said dents, combined with the warpsupportingrod adapted to be placed between the warp-threads to divide them into two sheets or layers, a rest or guide for said rod, and lifters for said rod, and means to operate them, substantially as described.

3. The comb or reed having a series of forked dents, an expanding spring or holder for the dents, means to lift said dents, and the warp-supports fore and aft of said dents, combined with the warp-supporting rod adapted to be placed between the warp-threads to divide them into two sheets or layers, a rest or guide for said rod, and lifters for said rod, and

means to operate them, substantially as described.

4. The comb or reed having a series of forked dents, means to expand the same, and means to lift them, combined with the warp-separating rod, a guide or rest for said rod, and lifters, and means to operate them and thereby the rod, the dents operating the warp-threads e, and the rod acting upon the warp-threads f, to separate the warp-threads vertically for the formation of a shed to receive the leasethi'ead, substantially as described.

5 5. The warp-supporting rod adapted to be placed between the warp-threads to divide them into two sheets or layers, and a rest or guide for the said rod, combined with lifters and with means to operate the said lifters, sub- 10 stantially as described.

6. The comb or reed box, the rod h, the bracket on which it is moved, and the rockshaft and its arms b b If, combined with the HERMAN F. STRAW'. JAMES D. BUTLER.
