BERTRAND A. PARKES, OF BAREEN HILL, PENNSYLVANIA, ASSIGNOR TO THE PHILA- DELPHIA DRYING MACHINERY COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A
CORPORATION OF PENNSYLVANIA.
AUTOMATIC FABRIC-LOOP DRIER AND FEED FOR SAME.
To all whom it may concern Be it known that I, BERTRAND A. PARKES, of Barren Hill. in the county of Montgomcry and State of Pennsylvania, have invented new and useful Improvements in Automatic Fabric-Loop Driers and Feeds for Same, whereof the following is a specification, reference being had to the accompanying drawings.
The invention relates more particularly to devices for feeding plush, or other material that can only be handled on one side thereof, without injuring the fabric, to a drying machine, and forming said fabric in loops which are supported by poles or bars carried by an endless conveyer passing through the drying machine.
An object of the invention is to provide a feeding mechanism which contacts with one face of the fabric only, and which feeding mechanism for forming the loops may be intermittently operated at proper intervals, relative to the travel of the supporting poles carried by the endless conveyer.
A further object of the invention is to provide a supporting pole with means for engaging the back face of the fabric, which means effectively hold the fabric loop from sliding on the pole, so that said loops may be made of uniform length, and thus maintained during the entire drying operation.
These and other objects will in part be obvious, and will in part be hereinafter more fully disclosed.
In the drawings which show by way of illustration one embodiment of the invention, Figure I, is a plan view of the receiving end of a drying machine, having my improvements applied thereto. Fig. II, is a side view of the same. Fig. III, is an enlarged detail view showing the manner of intermittently controlling the feeding drum for the fabric. Fig. IV, is a view on the line IVIV of Fig. III. Fig. V, is a sectional view on the line V, V, of Fig. IV.
The drying machine to which my invention is applied is of the usual construction, and comprises an inclosed casing 1, to which is attached asupporting frame 2, for the feeding-in device, and also for the endless conveyer 3. Said machine is formed with guide bars 4:, arranged in proper position for supporting the poles during the time that the fabric is carried thereby, and guide Specification of Letters Patent.

bars 5, for supporting the poles and the endless conveyer during the return movement thereof. This endless conveyer runs over suitable sprocket wheels 6, 6, located at each end of the drying machine, and is driven in any suitable way so as to have a slow continuous movement. The endless conveyer consists of two sprocket chains which are connected at intervals by angle bars '7 (see Figs. III and V). Located on each angle bar is a pole 8, which is preferably of wood, and is formed substantially rectangular in cross section. A series of pins 9 (see Figs. IV and V) are inserted in the poles, and are so disposed that the points of the pins project slightly from and through the corner of the pole over which the fabric is laid in forming the loops.
The fabric is led over a stretcher bar 10, carried at the outer end of the supporting frame 2, and thence over a feed roller 11. This feed roller is journaled in suitable bearings in the frame, and is provided with a bevel gear 12, at one end thereof, which engages a bevel gear 13, on a driven shaft 14 (see Fig. I). This driven shaft revolves the feed roller continuously. After leaving the feed roller 11, the fabric is led underneath a smoothing roller 15, and thence over a feed drum 16. This feed drum is journaled in suitable bearings 17, carried by the supporting frame 2.
It will be noted that the fabric is so led through the machine that the plush face thereof is out of contact with either the continuously operating feed roller, or the feed drum. After leaving the intermittently operated feed drum 16, the fabric passes over a second guiding and feed roll 18, also journaled in the supporting frame 2. This guiding roll 18, is so positioned that the fabric passing over the same will pass between the supporting poles 8, carried by the endless conveyer, and the supporting poles are so arranged that the pins 9, will be moved through the movement of the poles into con tact with the back face of the fabric.
In Fig. II of the drawings, I have shown the fabric fed so as to form a loop 19. Upon the completion of the loop, the pole 8, as shown in the figure, contacts with the fabric, the pins engage the same, and these pins will support the loop and cause a new loop to be formed between the pole and the next following pole. As soon as the pole is brought into engagement with the loop, and the loop is completed, means are provided for stopping the movement of the drum until said pole is moved sufficiently to bring the space between said pole and the next following pole underneath the feed of the fabric from the roll 18.
The drum is intermittently rotated by the following means: At one end of the drum there is a belt wheel 20, (see Figs. I and III) over which a belt 21, runs, and this belt also runs over a belt wheel 22, which is affixed to and travels with the bevel gear 12. The belt 21, is preferably slack. ll. belt tightener consisting of a roll 23, carried by the outer end of the lever 24., fulcrumed on a suitable bracket carried by the supporting frame 2, rests on said belt. Said lever at its opposite end is provided with a weight This weight normally lifts the roll 23, from the belt, and allows the belt to run substantially free with little friction on the pulley 20. An operating lever 26, pivoted at 27, to the frame, and is formed with an inclined cam member 28, at its free end, which is normally disposed in the path of movement of the poles S. The other end of this lever 26, is provided with an adjustable arm 25), which carries a stop shoe 30. This end of the lever also is formed with a lug 31, through which a rod 32, passes, and suitable nuts are threaded on the outer end of the rod. The upper end of the rod 32, passes through a suitable lug in the lever 24, and on the side of the fulcrum of the lever 24-, adjacent the roll 23. A downward movement of the lever 26, will pull down on the lever 23L, tightening the belt and causing the drum to rotate while an upward movement of the lever 26, will release the belt. The drum 16, is provided with a cam segment 33. The stop 30, as shown in Fig. III, rests against the end of this cam segment, and the drum is held from rotating. As soon as a pole 8, passes underneath the cam member 28, the lever 26, will be swung so as to move the stop shoe from the end of the cam segment on the drum, which will release the drum, and this downward movement of the lever 26, pulls down on the rod 32, tightens the belt, and causes the drum to rotate. The drum will continue to rotate notwithstanding that the pole passes from beneath the cam member 28, as the shoe 30, rests against the outer face of this cam segment 33. When the drum has nearly completed a full revolution, the stop shoe passes off from the end of the cam segment which is inclined as at 34:. This allows the stop shoe to move back into the path of travel of the end 35, of the cam segment. It also releases the roll bearing on the belt, but the drum will continue to rotate through the friction between the wheel 20, and the belt, until said cam segment strikes against the stop shoe, which will prevent further rotation of the drum.
The fabric passing from the feed roll 11, to the drum is formed in a large loop as indicated in Fig. II. This loop increases in size when the drum is at rest, and when the drum is in movement, the loop will be decreased in size as the feed of the drum is faster than that of the continuously operating feed roller 11. This will be obvious from Fig. II, of the drawings, which shows that the surface speed of the drum while moving is greater than the surface speed of the feed roller 11. I am able by this arrangement and proportioning of the parts to feed the fabric continuously and intermittently to the supporting poles. The supporting poles may, therefore, be moved continuously engaging and holding the fabric, while the drum is at rest, and positioning a space between the poles into which the fabric is fed in loop form through the action of the rotation of the drum. The guiding roll or feed roll 18, is connected by a suitable chain 36, to the drum, so that it is positively rotated and the surface speed of the roll 18, is substantially the same as that of the surface speed of the drum.
From the above construction it is a ppareut that I have provided a feeding mechanism for a drying machine, in which the intermittently operated feeding drum is controlled by the conveyer which supports the web, and, therefore, the placing of the web on the poles of the conveyer is automatically accomplished.
It will also be obvious that by the above mechanism the fabric placed on the support ing poles is engaged by the feed rollers on the back side thereof, which permits the feeding in and drying of plush or other material which can only be handled on one side thereof, without injuring the fabric.
It is understood, of course, that in the finishing of plush before drying, the plush is passed through a machine while wet to straighten the nap, and, therefore, it is es sential that in the feeding in, the plush shall be handled by mechanism which does not contact with the plush surface.
It is obvious that minor changes in details of construction and arrangement of parts may be made without departing from the spirit of the invention as set forth in the appended claims.
Having thus described my invention, I claim:
