DRYING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 74%429, dated November 17, 1903. Application filed May 2. 1203. Serial No. 155,273. (No model.)

.the apparatus is to-dry card packages of books and eyes, but, as will be understood,

it may he used for the purpose of drying other objects and still be within the scope of my invention. 7

In the manufacture of hook and eye card packages, the hooks and eyes are first sewed upon a card, after which a strip of paper or other suitable material is pasted upon the back of the card over the stitches formed in the operation'of securing the hooks and eyes to the card. I

After this has been done, it is necessary to subject the hook and eye packages to a drying process, and the packages should be held or retained in a perfectly flat condition during the time they are being dried. v

The object of the present invention is to provide suitable means for drying the hook and eye card packages, and at the same time retain them or hold them in a flattened condition. A convenient form of mechanism for this purpose is described herein and illustrated in the accompanying drawings, forming a part of this specification, and in which,

Figure 1 is a side elevation,

Figure 2 a longitudinal vertical sectional elevation, and

Figure 3 a top plan view of the mechanism employed.

In the drawings,

1 designates supporting standards located at opposite ends of the apparatus, and 2 des- Upon the said standards a boxing or casing 3 is secured.

Located at opposite ends of the apparatus, and within the boxing or casing 3, are rollers 4 mounted upon shafts 5, rotatably supported in bearings 6.

As depicted in the drawings, the bearings 6 are secured directly to the supporting standards 1. It is to be understood, however, that these rollers may be supported in any suitable and convenient manner directly upon the sides of the boxing or casing 3.

Located upon the outside of the boxing or casing 3, and supported in a manner similar to the rollers 4, are two rollers 7, the upper one of which is in the same horizontal plane as the lowest one of the rollers 4, located at the same end of the boxing or casing 3, while the lower one of the rollers 7 is located below the last-mentioned series of rollers 4 and in the same plane as the lowest roller of the series located at the opposite end of the boxing or casing.

Secured upon the top of the boxing or casing, and within the transverse central vertical planes of the two series of rollers 4, are rollers 8 and 9, the latter rollers being adjustably mounted for a purpose to be hereininafter explained.

As illustrated, the shafts 10 and 11 of the rollers 8 and 9 are mounted in bearings having screw-threaded connection with a horizontally arranged screw-threaded rod 12 adapted to be rotated, and the rotation of which causes a bodily movement of the shaft bearings, as the said rod is held against longitudinal movement.

It is obvious that any other suitable mechanism may be employed for adjusting the rollers 8 and 9.

Centrally located with respect to the apparatus, and with respect to the boxing or casing and the end supporting standards, are guiding and supporting rollers 13 arranged in alternate staggered relation upon opposite sides, respectively, of the centrally disposed supporting standards 2.

As illustrated, the shafts 14 upon which the said rollers are mounted are supported in bearings 15 which are secured to the central'standards 2, but it is to'be understood that the said shafts may be supported directly upon the sides of the boxing or casing 3.

16 designates smallguide rollers located at the bottom and at the top, respectively, of the boxing or casing 3.

Supported upon the

rollers

4, 7, 8, 9 and 13, are

conveyer belts

17 and 18, the former of which is designated herein as the outer conveyer belt, and the latter as the inner conveyer belt. The main portions of the conveyer belts are located and travel within the boxing or casing 3, as shown in drawings.

In the operation of the apparatus, it will be found that the belts stretch and become too loose for satisfactory use; or it may happen that one of the belts (either the inner one or the outer one) may stretch more and therefore become looser than the other. To overcome this difiiculty and maintain the belts in proper tension, the adjustable rollers 8 and 9 are provided.

It is obvious that if the roller 8 is moved toward the rightin Figure 2 of the drawings, the tension of the outer belt 17 would be decreased; or, if on the other hand, the said roller were moved toward the left, the tension of the said belt would be increased.

Referring to the other side of the apparatus, it will be seen upon inspection of Figure 2 of the drawings, that if the roller 9 were moved to the left, the tension of each of the belts would be decreased.

If the roller 8 were moved at the same time to the left a corresponding distance, the outer belt would remain at the same tension while the tension of the inner belt would be decreased.

Upon adjusting the said roller 9 toward the right in Figure 2, the tension of each of the belts is increased. If at the same time the roller 8 be adjusted toward the right, in the said figure, a corresponding distance, the tension of the outer conveyer belt 17 would remain the same.

As a means for causing the travel of the conveyer belts, I have provided the driving band wheel 19, which is mounted upon one end of the shaft, upon which the upper one of the centrally located rollers 13 upon the right hand side of the centrally disposed supporting standards 2 is supported.

It is obvious, however, that this driving band wheel may be otherwise supported and in difierent relation to the other elements of the apparatus.

The said driving wheel is driven by means of a band 20 having connection with suitable power mechanism not shown. Also mounted upon the same shaft as the band wheel is an elongated driving pulley 21, provided with a series of grooves adapted to receive the loops of driving cords 22 and 23, which extend in opposite directions to pulleys 24 and 25, mounted upon the shafts upon which the two series of rollers 4 are mounted. The band wheel,driving cords,and conveyer belts travel in the direction indicated by the arrows in Figures 1 and 2 of the drawings.

To increase the temperature of the region within the boxing or casing 3, for the purpose of quickly drying the card packages, I have provided the pipes 26 located in the bottom of the said boxing or casing and through which a heated fluid is passed. be understood, that these pipes may be heated by the use of hot water or steam; or that any other suitable means may be employed for this purpose.

It will be observed that the outer and inner conveyer belts are separated from each other near the bottom of the boxing or casing as indicated in Figure 2 of the drawings.

It is at this point that the card packages of hooks and eyes are delivered upon the top of the outer conveyer belt from a delivery chute 27. The cards are carried from this point between belts back and forth through the boxing or casing until they reach the upper portion of the boxing or casing, where the belts are again separated as indicated in Fig ure 2 of the drawings. The card packages at this point are supported upon the upper side of the inner conveyer belt and carried along until they are knocked off the said belt by means of the knock-off strip 28, which is arranged diagonally across the belt. The weight of the said strip is supported by the said belt and the strip is capable of vertical movement, being guided in its vertical movements by the vertical rods 29 with which it loosely engages. While permitting vertical movement of the strip, the rods 29 prevent the strip from moving laterally, that is to say, in the direction of travel of the conveyor belts. As the cards are removed from the belt by the knock-on? device 28, they fall into a discharge chute 30 which directs the cards into a suitable receiving receptacle not shown.

After the strips of paper or other suitable material have been pasted upon the backs of the cards bya suitable mechanism, not shown, and which forms no part of this invention, they are delivered to the delivery chute 27, and from this chute are directed upon the upper side of the outer belt near the bottom of the apparatus, as clearly shown in Figure 2 of the drawings, as above stated; and, as has been already indicated, the cards travel back and forth'between the inner and outer belts within the heated region of the boxing or casing 3, until they reach the knock-olf device 28, where they are removed from the belts and directed into the discharge chute 30.

Having thus described my invention, I claim- 1. In a drying apparatus, in combination, an endless conveyer, and a knock-ofl'f strip supported by the said conveyer, substantially as described.
