wEB-sELvAdE GUIDE.

SPECIFICATION forming part of Letters Patent No. 568,884, dated October 6, 1896.

Application filed April 3, 1895. Serial No. 544,329. (No model.)

To (LIZ 'wiwi/t it 11m/j concer/Lf:

Be it known that I, EDGAR STEVENS, a citizen of the United States, and a resident of Lawrence7 in the county of Essex and State of Massachusetts, have invented a certain new and useful Improvement in lVeb-Selvage Guides, of which the following, taken in connection with the accompanying drawings, is a specification.

The object of my invention is to provide a durable, efficient, and inexpensive apparatus, which I term a web-selvage guide, applicable to tentering and' drying machines for the sole purpose of directing and guiding the edges or selvages of the fabric in direct lines upon the chain hooks or point-s forming a part of the mechanism of said centering-machines as the fabric enters therein.

My invention to this end consists of right and left bed-plates movably attached to the corresponding sides of tentering or drying machines at the receiving end thereof. The adjacent sides of these plates are thickened to receive a series of interchangeable projecting guides, which, in combination with the vertical guard rising' from the bed-plate, serve to confine and direct the edges of the web or fabric smoothly into the tentering-lnachine until they are impaled on said points.

A specific description of the several features of my invention will be ascertained by referring to the drawings annexed, wherein- Figure l indicates in plan the receiving end of a tentering-ma'chine to exhibit the location and method of attaching my improved invention. Fig. 2 is a perspective of the right-hand apparatus detached, the direction and position of the fabric-selvage being shown in dotted line. Fig. 3 designates a transverse vertical section through dashed line 3 3 of Fig. 2. Fig. 4 is an aggroupment of guidepieces, which are modified constructions of the guides organized in the apparatus.

Similar letters designate like features throughout the several views, referring to which- A designates the bed-plate. Its taking edge A, adjacent to the center of the tentering-machine, is bored horizontally, as at B C.

D, to receive in relative order the attachments having relations to the fabric-viz., the bifurcated guide-piece E, within which the edge of the fabric is confined as it leaves the apparatus, the web-connected guide-bars F F2, under which the fabric or web K is drawn, the supporting guide-piece G, over which the-web edge is conducted and which projects suiciently to insure the safe carriage and prevent the sag of the fabric, weighted by moisture, from withdrawing or receding from juxtaposition with the edge A of the bedplatel A. The outward edge of this guide G is downturned, as at G', to facilitate the drawing of the edges of the web from the center outwardly as it moves toward the chain-points L, while the function of the web F3 is to prevent any tendency of the full- Y ness in the fabric to ride up and crowd the selva-ges too closely against the taking edges A. Said guide-pieces are mounted on the bed-plate and secured in a vertical position by their respective set-screws I-I, which have their bearings against the several Shanks I. The bed-plate A is further provided integrally at its forward end with the vertical guard A2,

rising above the plane of the working edge A', and its purpose is to prevent overriding of the fabric edges as they are drawn laterally against the taking edges A of said plates and also to prevent the projecting side loops of thread resulting from the sewing of the various pieces of the web together to unite them catching over any obstacle, as sometimes occurs in the absence of such a guard.

The guide-piece E is provided with the slot E', which, receiving' the selvage of the fabric, restricts any vertical undulation while directing it upon the chain-points L. rIhe rounded corners E2 of one side of this guide are for the purpose of facilitating the passage of the selvage, which has obstructions that sharp corners would not avoid, in the nature of what are known technically as matchholes, morefrequentlycut in the edges of the fabric by the dyers,y who from these cutout portions match the same color to subsequent weavings.

In the under side of the bed-plate A will bev observed the recess A3, adjacent to the taking edge A. This is for the purpose of adjustment vertically closer to the chain-points of the tentering-machine when desirable.

J J designate the four-Way apertures in the bed-plate for the reception of the screwn IOO bolts K K, through which my apparatus is adjustably secured to the bed of the machine.

Having described the operation and construction of my improved invention, I desire to secure by Letters Patent, and I claim- 1. In a tentering-machine, a base-plate having a thickened taking edge provided in the under side with a longitudinal depression A3, and also provided with a series of horizontal recesses, in combination with tentering-chain pins L, a series of guide-pieces received and supported in said recesses and coacting to maintain the position of the fabric as it is drawn through the machine, the vertical triangular-shaped guard A2 forming an integral part of each taking edge adapted to restrain overriding through fullness of the fabric edges as theyare laterally drawn against said edge, the four-way apertures J for proper adjustment to said tentering-machine,l and the means substantially as illustrated for attaching said bed-plate thereto, all for the purpose and in the manner specified.

2. In a tentering-machine the combination with bed-plate of the double guide-bar having a connecting-web adapted to restrain the fullness of the cloth from encroachment and overriding of the selvages, and provided with supporting-Shanks whereby it may be secured to the bed-plate, the bifurcated guide-piece,

Aeach arm of which is provided with rounded corners in the direction from which the fabric enters adapted to prevent a vertical undulatory action of the selvage while being directed upon the chain-pins of the tenteringmachine, and also provided with a shank for its attachment to the bed-plate substantially as specified.

3. The bed-plate A, provided with a vertical guide A2, the double guide-bar, the bifurcated guide-piece E and theineans for sus taining said double, and bifurcated guides to said bed, in combination therewith the guide? piece G and the double guide-bar having the coacting web E3 substantially as and for the purpose set forth.

4. The combination of the bed-plate andV guides, with the additional supporting guidepiecc G downturned at G on its outward edge, which extends far enough to prevent the sagging of the wet fabric from withdrawing it from juxtaposition with the edge of said bedplate, and the raised web F3 serving to prevent the fullness of the fabric from riding up and crowding the selvages closely against the said edge substantially as set forth.

5. The bed-plate A having a raised vertical guard A2 at its working edge in combination with a double guide-bar provided with a web F which is parallel to said guides and arranged for holding down the fabric, a support over which the fabric passes below the said web and guides su bstan tiall y as set forth.

6. In combination with a bed-plate, aseries of guides removably socketed in the said plate, one of said guides being bifurcated to allow the passage of the fabric through it, another guide being below the fabric for sup porting the same as it travels, and other guides of the series being above the said fabric on each side of the said supporting-guide substantially as set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 16th day of March, A. D. 1895.

Y EDGAR STEVENS.
