WILLIAM M. BARNES, OF PHILADELPHIA, PENNSYLVANIA.

CLOTHES-DRIER.

SPECIFICATION forming part of Letters Patent N 0. 684,77 6, dated October 22,1901.

Application filed July 14, 1900.

T0 ctZZ whom it may concern:

Be itknown that 1, WILLIAM M. BARNES, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in- Clothes-Briers, of which the following is a full, clear, and exactdescription,reference being had to the accompanying drawings, which form part of this specification.

My invention, speaking generally, belongs to that class of driers in which the articles to be dried are carried by an endless carrier and, further, in carrying the goods secured to the endless carrier through a heated room, the goods being dried in their passage through this room.

My invention has for its object to accomplish the drying in a more thorough and certain manner.

To that end, speaking generally, my invention consists in a carrier which traverses the drying-room on edge and passes around guiding-wheels on vertical axes. By this construction any number of traverses or turns in the drying-room may be made without the guiding-wheels interfering with the articles carried by the carrier, and thus may all be at the same level in the room, whereby the articles are constantly subjected to the most eflioient temperature in the room. Further, the carrier is supported from substantialvertical movement independent of the guide-wheels, so that the carrier is prevented from leaving the guide-Wheels. Further, I provide pins projecting from the carrier and beyond the line of the guide-wheels for attaching the article to the carrier.

Further, my invention comprises certain improvements in the drying-room itself and the relation of the heating medium, carriers, 850., to each other whereby the best result is obtained; and, further, it consists in stripping devices which automatically remove the articles from the carriers after they have passed through the drying-room.

It further consists in certain details which will be fully hereinafter described.

I will now describe the embodiment of my invention illustrated in the accompanying drawings, although except as the samemay Serial No. 23,560. on; model.)

hereinafter be specifically claimed I do not intend to limit myself to the specific details of this embodiment.

In the drawings, Figure 1 is a front view. Fig. 2 is a section on the line 2 2 of Fig. 1. Fig. 3 is a section on the line 3 3 of Fig. 1. Fig. 4 is an enlarged plan view of one of the curved portions of the track. Fig. .5 is a sec tion on line 5 5 of Fig. 4. Fig. 6 is a perspective View of one of the chain-supporting trolleys and a portion of the chain. Fig. 7 is a sectional plan view of the stripper on line 7 7 of Fig. 8. Fig. Sis a front view elevation of the same.

A is the drying-room. This room is a foursided room provided at the front with the door a and the openings a a and on the back with the opening a near the floor. The purpose of the opening a is, as will hereinafter be described, to allow the damp heavy air to escape. The door a is for access to the drying-room. The opening 0; is to admit a carrier into the drying-room and the opening a for passage of the carrier from the dryingroom. On the sides and back of this room, starting near the bottom and extending upward therefrom, are the heatingcoils B. Within the drying-room and supported upon vertical axes are the guide-wheels G 0, one of these guiding-wheels (the wheel 0) being a sprocket driving-wheel. These wheels are all at the same level and are near the two ends of the room. These wheels are supported in the following manner:

D D are two beams extending from side to side of the room, one at each end of theroom. These beams are secured to the sides of the drying-room by brackets 61.. Secured to these beams above each wheel 0 C is a curved trackway E,havingdownward-projecting portions e and inward-projecting portions e", forming a slotted double trackway. (See Figs. 4 and 5.) This trackway is provided with a bearing E for the vertical shafts c c of the wheel 0 0. Between the beams and each pulley extends a straight trackway E, of the same construct-ion in cross-section as the curved trackway E. This straight trackway E is abutted to and secured to the ends of the curved trackway E. O utside the drying-room A and in line with the openings at and a are the guide-wheels C and C on vertical shafts. The guide-wheels C and C are secured in a manner similar to the guide-wheel C (E -that is, beams D and I) extend from the top of the drying-room, and to these beams are secured curved trackways E, having bearings E for the vertical shafts c and 0 supporting the wheels 0 and C Straight trackways E extend from these curved trackways, as within the drying room, thus forming throughout a trackway which is partially curved and partially straight.

The conveyer I which I have shown is an ordinarylink-belt conveyertraveling on edge. To this conveyer F at a plurality of points are connected shanks G, having at their upper ends the hangers g, forming a bearing for the short longitudinal shafts g, to each end of which shafts is secured a roller 9 The shank G is of such thickness that it can pass between the ends of the projections c of the trackway, allowing the rollers to rest upon the projection e of the trackways E and E. In order to diminish friction, the rollers g or their shaft may be provided with the ordinary ball-bearings. At a plurality of points project horizontally from the conveyer pins 9 one at each side and below the link proper. The eonveyer G passes around the wheels 0 C and the rollers 9 rest in and travel along the track ways E and E.

The goods are attached to the pins g and travel through the drying-room A. Near the outlet a and without the drying-room are the strippers H, one on each side of the conveyer G. These strippers are forked cams having forked ends 7L h set at an angle to the travel of the conveyor, so that when the pins 9 enter the fork the goods held by the pins are stripped off the pins.

The operation of the mechanism so far as it has been described is as follows: The goods to be dried are attached to the pins between the strippers H and the wheel 0 and suitable motion being given to the conveyor the goods are carried into the drying-room through the opening a and passed a number of times to and fro in the drying-room and then out to the strippers. By this construction, the conveyor being on edge and the goods supported beyond the wheels, any number of turns can be made in the drying-room, as the guiding-wheels in no way affect the operation and the conveyer may be maintained at all times at the same level in the room and at the point of most efficient temperature. Again, by the use of the tracks E and E supporting the chain there is no danger of the chain sagging off from the guidewheels due to expansion by heat or from any other cause. Further, the guide-wheels and trackways are connected with each other and the eonveyer is suspended from the track- Ways and passes around the guide-wheels. This insures that the expansion or contraction of the parts will take place together. Motion is given to the conveyer through the sprocket-wheel O, which wheel is driven in the following manner:

I is the main driving-shaft, driven in any well-known manner. Upon this shaft is the cone-pulley 11. Upon the shaft J is a conepulley j. A beltj connects the pulleys i and j. On the shaft J is a worm J, meshing with a worm-wheel J on the shaft 0 of wheel C. By this means the wheel 0 is positively driven and in turn drives the conveyer F. If necessary, more than one driving-wheel may be used.

Journaled in a hanger 76, secured to the top of the interior of the drying-room A and central thereof, is the shaft 7t" of the fan K. The fan K is above the conveyor G and the shaft 7; projects through the top of the drying-room A, having on its upper end a pulley M, which is connected by a belt]; with apulley 7,5 on the shaft I.

By the construction described it will be seen that the heating-coils are at the sides of the room and the fan above the conveyer. The air rises from the bottom along thesides, being heated by the heating-coils, and the fan forces it downward through the center to the bottom, from which it again rises, as before described, thus producing a perfect circulation. Any damp air escapes through the opening a and fresh air will be admitted through openings ct and a Taking the apparatus as a Whole it will be seen that the use of the conveyor on edge enables any number of traverses in the dryingroom desired to be made. It will further be seen that the con veyer is supported independently of the guide-wheels and is thus prevented from sagging or leaving the guidewheels, and the goods in no place come in contact with or are affected by the guide-wheels. Further, the arrangement of the heatingcoils is at the sides of the room and the fan above the conveyer causes a perfect circulation of the heat and a complete and rapid drying. While I have shown the conveyer as a link-belt conveyer, I do not intend to limit myself to that specific form of conveyer. I also desire it to be understood that the arrangement of drying-room with the heatingcoils at the sides of the room and the fan above the conveyerhas advantages whether the conveyer be used on edge or flat.

Having now fully described my invention, what I claim, and desire to protect by Letters Patent, is-
