{CHAIN-GUIDING BOX FOR CLOTH STRETCHING AND DRYING MACHIY'NES.

SPEGIFIGATIONfor'ming part of Letters Patent No. 499,889, dated June so, 1893.

I To all whom it may concern.-

which the following is a specification, reference=beinghad therein to the accompanying This invention relates to improvements in that class of tentering-machinesin which the cloth is stretched between. two chains which travel at a uniform rate of speed, and operate one on each side of the machine.

The object of myimprovement is to provide'the chain-boxes with simple, inexpensive, durable and efficient means for guidingthejchairflwvhich means shall be easily reversed, transposed and adjusted to increase the durability of said boxes. I attain this object by the construction illustrated in the accompanying drawings, in'which- Figure 1 represents a transverse vertical section of a portion of a tentering-machine provided with chain-boxes constructed in accordance with my inyention. Fig. 2 is a side view of one of the boxes on a larger scale with a chain-link therein. Fig. 3 is atr'ansverse vertical section of the chain-box with chain link therein. Fig, 4 represents a chain-link in side and top view. s

In said drawings A represents a portion of the frame of a tentering-machine carrying as usual, a certain distance apart, a series of rods B, each one having at one end a bevel pinion b meshing withga pinion on a horizontal line of shafting (not shown), by which a few rotations can be given to the rods to regulate the distance between the chain-carrying plates 0 retainedby said rods in accofilance with the width of the cloth is operated upon. For this purpose, the rods B have right and left hand screws cut thereon, that are received in nuts c secured to the platesG. To the top and bottom of said plates, the chain boxes are secured.

Each improved chain box consists of two angle bars D and D retained at suitable distance apart by sleeves E and bolts 6 passing through said bars and sleeves, the inner bar D being also secured to the flange on the edge of theplate O by means of bolts e shown Application-filed septemb'e r 5, 1892. I serial No. 446,097. iNo model.)

in Fig. 1. The'bars D and D have their angular webs (1 turned away from the interior of the chain box, of which said bars form the top and bottom walls.

angular bars F, by means of bolts f passing through slots f in said bars Fand-throu'gh perforations in the web (1. The inner edges of the bars F are thus retained at a suitable distance from each other to maintain between them a-slot F for the free passage of the gill-- plate's g carryingthe neutering-hooks g Said gill-plates project from one side of the chain links G, which may ,be of any suitable con-, struction. By having the slots F in the bars.

F'equidistantfrom the top and bottom edge thereof four distinct steel wearing surfaces for the side of the chain are-obtained consecutively from each bar. edge is worn, it can be turned to the outside, and when this side is worn, the bar can be turned upside down and its two sides used. Asthe steel bars F are of rectangular form, they can be easily polished to present a smooth Surface for the chain.

I am aware that English Patent No. 5,459 of 1889 shows double flanged cast bars retained together in pairs with their flanges turned toward each other to form chain boxes,

and that said double flanged plates are reversible, but said boxes differ from mine-in the location occupied by the flanges or webs of the bars toward each other, and by the absence of any plain reversible rectangular bars.

as F, adjustably secured to the webs of the bars and constituting the wearing face of the v chain-box;

- Having now fully described my invention, Iclaim l In combination with the frame of a tentering machine, a chain box consisting ofytwo angular bars having their vertical webs turned away from each other, sleeves and bolts therethrough to retain them united apart, and bars F adjustably and reversibly secured to the vertical webs of the angle-bars substantially .as described.

In testimony whereof I affix my signature in presence of two witnesses. I
