CLOTH-TENTERING MACHiNE.

EPE-CEFECATQN forming part of Lettexs Patent No. 350,009, dated September 28, 18136.V

Application filed lIune 1l, 1886. Serial No. 201,806.

State of Rhode Island, have invented a new' 5 and useful Improvement in Oloth-Tentering Machines; and I do hereby declare the following specification, taken in connection with the accompanying drawings, forming a part ot' the same, to be a description thereof.

This invention relates to those well-known machines for tentering cloth in which travelingchains provided with clamps or tenter hooks or pins are caused to move along two side rails and carry the cloth through the drying-room. In one class of these machines these rails have longitudinal reciprocating movements imparted to them for the purpose oi.' producing a desirable finish on the cloth, and most of these machines are arranged so 2o that said rails can belaterally adjusted with relation to each other to receive fabrics of dii'- ferent widths. The machines arc furnished at the delivery end with a roller which recei ves the fabric from the traveling or conveyer chains, and acts as a guide in deliveringl the fabric from the machine. In machines whose rails are given longitudinal reciprocating movements this delivery-roll has been pivoted to the rails at points near the outer edges there- 3o of-that is, at points outlying the edges of the fabric-and as the roll swings with the rails the cloth in passing over the roll has been alternately slackened and tightened on the roll from the central line ofthe fabric toward its edges, thereby drawing it out of shape and straining it. In machines having the rails laterally adjustable with relation to each other the delivery-roll has been made telescopic in form, in order that its length might be increased and diminished as the rails were moved farther apart or brought nearer together to accommodate fabrics ot' different widths. In a roll of telescopic form one or more of its sections must be the larger, which produces one or more circumferential ridges on the roll. These ridges crease the nished fabric, and thereby give it an undesirable appearance.

The objects of the invention are to prevent 5o the fabric passing through the machine from being slackened and tightened on the delivery- (No model.)

' roll, as described, and to prevent the creasing ofthe finished fabric by ridges on said roll, and yet the roll be able to deliverany width of fabric within the limits ofthe machine.

To these ends the invention consists in pivoting the delivery-roll to or with relation to the side rails ofthe machine at points substantially in vertical planes passing through the gripping-faces of the clamps or the tenter-pins, 6o whereby a slackening and tightening of the fabric on said roll is avoided, and in making the said roll without peripheral ridges and mounting it s0 as toallow of a lateral adjustment of the rails, as will hereinafter appear.

In the accompanying drawings, Figure l. represents a top view of the delivery end ot' a tenteriiig-machine embodying theinvention, (portionsof the salire being broken away,) the rails of which havelongitudinal reciprocating 7e movements and are adj ustable laterali ywith rclation to each other. Fig. 2 shows a side view of the same, a portion ofthe mechanism shown in Fig. l for reciprocating the rails being omitted. Fig. 3 represents an end View of a 7 5 portion of the delivery end of the machine, showing the manner in which the deliveryroll is mounted, the mechanism shown in Fig.

1 for reciprocating the rails being omitted. Fig. 4 represents a similar View of a machine, 8;) showing how the ordinary delivery-roll is mounted. Fig. 5 represents a topview of a portion of the side rails of the machine, and is a diagram illustrating the difference between pivoting the delivery-roll in accordance with S5 my invention and in the ordinary Way.

A A are the side rails of the machine, which are mounted in a Well-known manner and support the traveling or conveyer chains B B C is one of the screws forlaterally adjusting 9 the rails with relation to each other, the said screw having central bearings in lugs c on the arm C', (which arm is pivoted upon a standard, 02,) and being threaded through blocks a a', to which the rails are pivoted. The

chains B B are provided with Well-known clamps b b or well-known tenter-pins, b, Fig. 3, for holding the fabric at its edges, and said chains pass over sprocket-wheels at each end roo of the machine, those, D D, at the delivery end of the machine being attached to gears E E, re-

I s peetivel y. Meshing with these gears are two pinions,one.of which, f, is shownin Figs. 1 and 2, and these pinions are mounted upon a shaft,

F, centrally pivotedon a standard. G, so as to swing. The shaft F is furnished with a bevelgear, j",l through which revolution is imparted to the shaft from the usual source of power;-

The `shaft F also passes through blocks g g', which are pivoted to the rails. A swinging motion is given to the shaft F, and thereby a reciprocating motion to the rails, by a crankand roll upon standards J J.

revolve.

As thus far described, the machine iswell known and understood by builders'and users of tentering machinery.

K, Figs. l, 2, and 3, is my improved de liveryroll, which has an unbroken surface, and is mounted to revolve in arms k, secured to a rod, L,Kthe said arms and rod forming a yoke or frame in which the roll is mounted to To the rod L is preferably centrally secured a stud, Z, which enters a bracket or support, M, and pivots the rod thereto. Upon the rod L sleevesl N N are mounted to slide, said sleeves being provided with depending studs a n', which enter arms O10', respectively attached to the rails A A', and pivot said sleeves, and consequently the rod L and roll K, to said arms. The centers of the pivotal connections between the sleeves N N and arms O O are, located substantiallyin vertical planes passing through the gripping faces or lines ofthe clamps b b', or the tenter-pins bi, as shown in Fig. 3. I say substantially `because I prefer to arranger these pivotal centers as nearly as possible vertical] y' above the edges of thefabric, I, held by the clamps or] pins,

and shown by dotted lines; but as' the edges of the fabric are but a fraction of an inch from the gripping faces or lines of the vclamps or the tenter-pins, even then the centers of pivotal connection would be substantially in vertical planes passing through said clamp-faces or the pins. It will be readily seen, therefore, that those portions of the` roll-K with which the edges of the cloth come i n contact will have the same amount of reciprocating movement as the edges of the fabric; consequently the fabric will not be slackened and tightened Yon the roll during its delivery, as it would be upon a roll pivoted to the rails near the outer edges of the latter, as will soon be illustrated.

Referring to Fig. 4, K shows 'an ordinary telescopic roll, which is' composed of three sections, lc k2 le, lthe end sections being greater in diameter than the middle section. This 4roll is mounted to revolve in studs p p', which' are pivoted in standards p2 p near theouter edges of therails, according to the prevailing custom.

tact during delivery will have less motion than the edges of the fabric. This will ybe clearly seen by an examination of Fig. 5, in which the been full y advanced, the left-hand edge of the fabricll? will have been moved forward to the point s; but the vroll will only have advanced to the point s', in line with the'edge of the fabric, consequently the ,fabric will be slack on the roll from the center t of the former to its left-hand edge. On the'other hand, the reedge of the fabric back to the point u; but that portion of the roll in line with the fabries edge will only have retreated to u. Therefore the cloth will be stretched over the roll, increasing in tightness from the center t to the right-hand edge. Likewise, when the rail A is fully advanced, the right-hand edge of the `treat of the rail A will carry the right-hand fabric will be moved to the pointu; but the roll in line with the edge of the fabric will only have moved to the point c', causing a slackness of the cloth in that side; and by the retreat of the rail A the left-hand edge of the cloth will move to w, but the'roll in line with the edge of the fabric will only have moved to w', causing a tightness or strain of the fabric This slackness and tightness of the cloth on the roll distorts the fabric and injures it, and the sections 7c k2 being greater in diameter than the section k the. ridges k* at the junction of the sections crease the cloth and damage its appearance.

Referring to Figs. 3 and 5, it will be seen that as the centers of pivotal connection between the roll K and the rails A A are located substan tially in vertical` planes passing through the `edges ofthe fabric those portions of the roll with which said edges should come in contact will beadvanced and retracted by the movements of the railsl equally in amount with the edges of the fabric.A (The dotted lines y y, Fig. 5, indicate the axis of the roll K in different positions.) Therefore the cloth will not be lslackenedor tightened on the roll during delivery, andbe thereby distorted.

In order that the roll K may be adapted for use with any width of fabric which can be tentered on the machine, the roll is made long are secured to the rails) will slide on the rod L, and in their new positions on said rod will vimpart,arproper, motion, to the frame k L and Vhen the l trally by means of the stud Z and bracket M. yet such central pivoting may be dispensed with, and one of the sleeves, as N, may be secured to the rod Lby a set-screw. dotted lines in Fig. 3.)

Vhat I claim as my invention, and desire to secure by Letters Patent, is l l. The combination, substantially as hereinbefore set forth, with the rails and traveling chains provided with clamps or tenter-pins, and means, substantially as described, for rcciproeating said rails, of a delivery-roll pivoted with relation to said rails substantially in vertical planes passing through the grippingfaces of the chain-clamps or tenter-pins, as described, Whereby a slackening and tightening of the fabric on the delivery-roll while passing over the same is avoided.

2. The combination, substantially as herein- (Shown by before set forth, with the rails and means, sub- 2o stantially as described, for laterally adjusting the rails with relation to each other, of a delivery-roll, a yoke or frame in which said roll is mounted. and connections, substantially as described, between said frame and the rails, whereby one or both of the rails may be slid laterally with relation to the roll.

3. The combination. with the rails A A', of the roll K, a yoke or frame, kL, in which said roll is mounted, a support, M, to which the yoke is pivoted, the arms O O', secured to the rails, and the sleeves N N', mounted on the yoke and pivotcd to said arms, substantially as and for the purposes specified.
