To all 'zr/om 'it may concern:

Be it known that we, ALFRED PORTER and J oIIN A. CLARK, both of the city ot Manchester, county of Hillsborough, and State of New Hampshire, have invented certain new and Looms; and we do hereby declare that the followingis at'nll, clear, and exact description ot' the same, reference being had to the accompanying drawings, forming a part of this specification, and in Whichl Figure 1 represents a top or plan view ot' our improved temple. Fig. '2 represents aA side view, looking in direct-ion ot' arrowB, Fig. 1.-

Fig. 3 represents7 upon anv enlarged scale, a section on line A B, Fig. l, looking in direcsame ligure. Fig. 4 -representsmalso upon an enlarged scale, a top or plan view ofl the lower jaw and burr or temple-roll' ot' our improved temple, the upper jaw or cap being removed to show the -other parts more fully. Fig. 5 represents, also and Fig. 6 represents,

upon an enlarged scale, a central longitudinal section through the jaws and burr-roll or" the temple on line B C, Fig. l, looking in direction indicated by arrow 2 of the same ligure; also on an enlarged scale'. a section taken on line C l), Fig. 1, looking in direction of arrow of the samelignre.

To enable those skilled in the art towhich l our invention belongs to make and use the same, we will proceed -todescribe oursaid invention more in detail.

In thcdrawings, the part marked represents a section of the front or breast beam ot' v the loom, over which the cloth passes as it is woven, and 'upon each end of said beam is arranged a metallic piece or plate, B, provided with a slot, a, whereby, by means of the bolt b and nut c, to or farther from the outer end of the breastbeam A, according to the width of the cloth.

Metal 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, to assist-in keeping thev said piece squarely onthe beam, and by the use of but one set-screw. The said piece is also provided with a circular restor seat, C, to receive the templellolder l), the rear part, D', of which lits against aange, E, upon the metal part B, and to which p'a-rt said metal'piece can be set nearer or curvedr temple-holder l) is secured by means of the screw-bolts d d, which pass through slots e e in the'part D', and screw into the part B, as indicated in Figs. l audS. mentsthe temples at each edge otl the web can be'adjusted toward or from each other, and they can also be lrocked back and forth or adjusted on curved seats C U, and be then secured in position, so as to cause-the ends ot' the temple rods or bars earryin g burnt-oils F to occupy a higher or lower positionvertically Withrelation to the breast-beam Aand the usual reed andlay in .advance ot` it, according to the proportions oi' the loom, as may be desired.

The part marked (l is the te1nple-'i`ramc, in Whicll't-he temple-rod His fitted to slirfie back and forth. The front part, l', is made in rect angular shape, to Alita rectangular hole in the guide-'loop or bearing part G', While the rear end of the temple rod or stem H is made round, to pass through a corresponding hole in the loop or guide part Gl ot' fra-me G. By

this mode of construction the temple rod'or stem H -can move back and fort-h in its guides or loop-bearings G G", and theformer bearing, being rectangular, rctainsthe stem in its proper relative position, and obviates all lo tatory motion,

, Frame G is fastened to the partl) by means of screw-boltsjj', passing through slots in the projecting part I ot frame G, and by means otl which slots and screw-bolts the temple can be set forward or back, as occasion in ay require.

Projecting laterally from the inside ot' the rectangular end of stem or tempie-rod H isa concave jaw, J, provided with a" series ot' parallel grooves, 1, in which the rows ot teeth 2 of the conical bur 1-roll F enter as said roll reA volves. The journals 3 4.- ot burr-roll F are supported, the former in the part H ot' the temple rod or stem Il, and "the latter in' the downwardlylproject-ing portion g ot' the cap or upper jaw, K. Said upper cap or jaw, in this instance, forms a part ot' the slotted piece H", which is secured to and forms a part of the rectangular end ot templo rod or stein H, said slotted part H" being secured to the other lpart ot' temple-rod H by vmeans of screws i and 6, the latter being shown by dotted lines in Fig. l.

'By these arrange;

' ceive the ratchet-wheel part drawn' a little more tant I its normal position.

` The has@ f nunron is formeel with a.

' ratchet-wheel part, L. A' slot or hole Vis formed in the side of the recta-11 guiar part H', to vre- L of the burrwheel F.

A-pawl, M ,is pivoted at 7 in afslot in the rectangular part H', to take into the ratchetteeth hof the ratchet-wheel L, as fully indicated in Fig. 6 of the drawings. The base ot vpawl M is provided with a ratchet-tooth, 8.

(See Fig. 6.) n From the foregoing description it win be seen that-'the lselvages of the cloth .will be than the cloth at the inner points f the burr-wheels; consequently the edges of `'the web of cloth, asV it is woven, are not allowed to be.' loose and slack,`,there by causing imperfect selvages.

' h., and these teeth may be made-thier or coarser,

as preferred.

Upon the temple rod or stem ll are arranged two spiral springs, N and 0,aipin, g,

being inserted between their inner ends in the rod H.

Y The outer end ot' spring N presses against y the ,shoulder -of the rectangular part HA of rod H, while'the outer end of spring O presses` against the loop-guide GrIl of the part "if By this arrangement of said springs th temple rod or stem H will be so operated upo' and held as to rest in the position shown in Fig. l; but when pressure is applied to its front end, spring` 0 will contract and 4allow the rod, with its temple, to move back; but

as soon, as said 'force is removed the action of spring O. will force Then,

again,l when force is applied in the opposite direction, spring N will contract, and

` allow ward; but the action of spring N, as soon as the rod andthe .temple to move torthe force ceases to act, will throw the Irod back "to its normal position again.

XVe have, therefore, produced a temple'centrally supported, but capable of moving forward' or back during' the operation of weav ing by means of a spring action,,and consequently the strain on the cloth and warpthreads 1s quite even and easy,

the threads. If preferred,piu g may be made adjustable, so as to enableV the 'operator to adjust the ten! sion of one or both of said springs. r By making the co'ncavity of the lower jaw or part, J, with 'a series of grooves, 1, in-which the burr-teeth 2 enter as 'diejr revolve, the cloth 'is retained upon said teeth, and is not. liable to slip ofi', and consequently the cloth is always retained in a uniform and perfect manner. It sometimes 'happens inmending threads, o r in picking onqtfthat it Vis convenient to have the jawsor pants J K `held back.. y

Then, again, -by the action ofpawl M, the burrf-rolls F can-y the rod or 'stem back to,

and notsuchfy as to tend to either tear the cloth or break For this purpose pawl M is provided with a catch, S, so that by simply pushing templerodv ll back, as shown inFig. :35, and. raising pawl M, so that its catch S-will strike against the rear edgelot' guideloop G', the parte will be retained in position, as shown in Fig. until the` attendant forces the pawl ill down, when spring() will force the parts iiirwar, as ,shown in Fig. l.4
