IMPROVEMENT IN LOOM-TEMPLES- Specification forming part of Letters Patent No. 188,538, dated March 20, 1877; application tiled December 2, 1876.

Figure 1 represents a top or plan view of our improved temple. Fig. 2 represents a side view, looking in direction of arrow 3, Fig. 1. Fig. 3 represents, upon an enlarged scale, a section taken on line A B, Fig. l, looking-in direction. indicated by arrow 1 of the same figure. Fig. 4 represents, also upon an enlarged scale, a top or plan viewof the lower jaw and burr or temple roll of our improved temple, the upper jaw or cap being removed to show the other parts more fully. Fig. 5 represents, also upon an enlarged scale, a central longitudinal section through the jaws and burr-roll of the temple on line B 0, Fig. 1, looking in direction indicated by arrow 2 of the same figure; and Fig. 6 represents, also upon anenlarged scale, a section taken on line C D, Fig. 1, looking in direction ofarrow 3 of the same figure. V

To enable those skilled in the art to which our invention belongs to make and use the same, we will proceed to describe our said invention morein detail.

In the drawings, the partmarked A represents a section of the front beam of the loom,

ther from the outer end of the breast-beam A..

Metallic piece B is provided with a flange, B, to fit against one edge of the breast-beam A,

' as indicated in Figs. 2 and 3. It is also provided with a circular or curved slot, 0, to receive the temple-standD, the rear part D of which fits against a flange, E, upon the metallic part B, and to which part temple-stand D is secured by means of the screw-bolts d d,

which pass through slots 0 e in the partD,

and screw into the part D, as indicated in Figs. 1 and 3.

By these arrangements the temples, at each edge of the web, can be. adjusted toward or from each other, and they can also be rocked back and forth on curved seats 0 0, and then secured in position, so as to cause the ends of the temples, carrying the conical burr-rolls F, to stand at a greater or less elevation, as may be desired.

The part marked G is the temple-frame, in which the temple-rod H is fitted to work back and forth, the front part H being made in rectangular shape, to fit a rectangular hole in the guide-loop or bearing part G, while the 1 rear end of the temple-rod or stem H is made round to pass through acorresponding hole in the loop or guide part G of frame G. By this mode of construction the temple-rod or 'sten H can move back andforth in its guides or loop-bearings G G. The former bearing, -being rectangular, retains the stem in its proper relative position and from all rotating motion.

Frame Gis fastened to the part D by means of screw-boltsff, passing through slots in the projecting part 1 of frame G, and by means of which slots and screw-bolts the temple can be set forward or back, as occasion may require. Projecting laterally from the inside of the rectangular end of stem or temple-rod H is a concave jaw, J, provided with a series of parallel grooves, l, in which the rows of teeth 2 on the conical burr-roll F enter as said roll revolves. The journals 3 4 of burr-roll F are supported, the former in the part H of the temple-rod 0r stemH, and the latter in the downwardly-projecting portion 9 of the cap or upper jaw K. Said upper cap or jaw, in this instance, forms a part of the slotted piece H, which is secured to and forms a part of the rectangular end of temple-rod or stem H, said slotted part H being secured to the other part of temple-rod H by means of screws 5 and 6, the latter being shown bydotted lines in Fig. 1. The base of burr-roll F is formed with a ratchet-wheel part, L, a slot or hole being formed in the side of the rectangular part H, to receive the ratchet-wheel partL of the burr-wheel F. A pawl, M, is pivoted at 7 in a slot in the rectangular part H, to take into the ratchet-teeth h of the ratchet-wheel L. as fully indicated in Fig. 6 of the drawings. The base of pawl M is provided with a ratchettooth, 8. (SeeFig.'6.)

From the foregoing description it will be seen that the selvages of the cloth will be drawn a little more taut than at the inner points of the burr-wheels; consequently the edges of the web of cloth, as it is woven,.are not allowed to be loose and slack, thereby causing imperfect selvage's. Then, again, by the action of pawl M, the burr-rolls F can not turn back, but are held in place as the cloth is woven suflicient to pass one tooth, h, and

these teeth may be made finer or coarser, as preferred. r

Upon the temple-rod or stem H are arranged two spiral springs, N and O, a pin, g, being inserted between their inner ends in the rod H. The outer end of springN presses against the shoulder of the rectangular part H of rod H, while the outer end of spring 0 presses against the loop-guide G of the part G. By

this arrangement of said springs the templerod'or stem B will be retained in the position shown in Fig. 1 when at rest and not acted upon by said springs; but when pressure is applied to its front end spring 0 will contract and allow the rod, with its temple, to move back; but as soon as said force is removed the action of spring 0 will force the rod or stem back to its normal position. Then, again, when force is applied in the opposite direction,

.spring N will contract, and allow the rod and the temple to move forward; but the action of spring N, as soon as the force ceases to act, will throw the rod back to its normalposition again. We have produced, therefore, a temple centrally supported, but capable of moving forward or back during the operation of weaving by means of a spring action; consequently the strain on the cloth and the warpthreads is quite even and easy, and not such as to tend to either tear the cloth or break the threads. If preferred, pin g may be made adjustable, so as to enable the operator to adjust the tension of one or both of said springs.

for this purpose pawl M is provided with a a catch, 8, so that the attendant, by simply pushing temple-rod H back, as shown in Fig. 2, and raising pawl M so that its catch 8 will strike against the rear edge of guide-loop G,

the parts will be retained in position, as shown in Fig. 2, until the attendant forces pawl M down, when spring 0 will force the partsd'on ward, as shown in Fig. 1.

Having described our improvements in loom-temples, what we claim therein as new and of our invention, and desire to secure by Letters Patent, is-- v v 1. The combination of the curved templesupporting piece D with the curved scat B.

and one or more holding and adjusting screws, (1, substantially as andfor the purposes set forth.

2. The combination of pawl M, provided with projection 8, with temple-rod H and frame G, substantially as and for the purposes set forth.

3. The combination of the curved templesupporting piece B, the curved seat D,.the frame Gr, andthe temple-rod H, substantially as shown and set forth. p y 1 4. The combination, with temple-rod H and its frame G, of the springs N and 0 and ;pin

g, substantially as and for the purposesset forth.
