DRIERi-CAR.

SPECIFCATON forming part of Letters Patent No. 686,514, dated November 12, 1901. Application filed March 18, 1901i Sial. N0. 511675. (No model.)

. Cuyahoga, State of Ohio, have invented certain new and useful Improvements in Drier- Cars, of which we hereby declare the following to be a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to the construction of cars usually used for holding clay and other products while being dried by means of articial heat. The purpose is to make a car both sti and light and composed of as few pieces as possible. Heretofore such cars have been constructed of either steel or castiron frames on trucks bolted together, upon which slatted frames riveted together rested. This construction necessarily makes them costly, heavy, and cumbersome for transportation by man-power. y

In our invention the car simplyconsists of one or more comparatively light metal plates provided with elongated perforations for ventilation. The metal from the perforations is left on the plates and pressed downward for stiffening-flanges. The edges of the plates also are pressed down for further stiifening the platform of the car. This is all done with one operation of a powerful press. If no large press is available, more than one plate necessarily has to be used and these riveted together to make one whole platform. The side flanges of the plate are preferably made to hang down vertically far enough to supportv the axles, and antifriction-wheel bearings can be employed to make the complete car.

In order to fully illustrate our invention, we have made the accompanying drawings to accompany this specification.

In the drawings, Figure 1 shows a bottom plan view of a car with a single platform. Fig. 2 shows an end view of the car in an upright position with a second platform at a distance above the car held there by supports. Fig. 3 shows a side view of the car with one platform with the supports broken away.

` Fig. 4. shows an enlarged view of wheel and supports. Fig. 5 shows a transverse section of same and also of a portion of car. Figs. 6 and 7 show side and transverse sectional views of a light form of car. In this case if no heavy load is run on the metal may be removed from the slots entirely.

In the perforated platform 1 we show the lateral slots 2 with the metal pressed down on both sides of each slot and forming depending iianges 3 and longitudinal slots with the metal cut out on one side of each slot and pressed down to form a depending flange on the other at 4.

Figs. 1, 2, and 3 showl the side lianges 5 forced down far enough to take in the axles 6, holes or slots 2O being punched out for that purpose. The axles 6 have threads cut on the ends at 7 far enough to take on two nuts 8 and the upright supports 9 and a washer 10 on the inside. A By these means the side flanges 5 are compressed between-the supports 9 and washers 10, thereby binding both side flanges together, the axle actingv as a binding-brace across. The wheels 11 are held in their place by pipes or sleeves 12 on the axles and washers 13 and 14 and ferrules 15. By changing the length of the ferrules 15 andpipes 12 the wheels are made to fit various gages of tracks.

The wheels 21 are bored out to admit balls or rollers 16, which are held in place by washers 13 and 14.

If desired, additional supports can be placed between the two axles and bolts simi lar to the axles secured with binding-nuts andrunning across under the platform.

.As stated before, for cars for light work light plates are used and perforated without the stiffening edges in the slots, the side flanges kbeing narrow where only one platform is to be carried. In such cars we run the supporting-bar 9 across under the platform and bend it down, as shown at 1.7, to support short axles 18 on one end, with the hangers 19 on `the other end, the hanger and bar being made wide enough to hold the rollers in the wheels in their places without the use of washers for that purpose.

By using several tiers of supports 9, as described, several platforms can be vcarried above each other.

We do not confine ourselves to any particuf Ico lar arrangement of these perforations, as they have to be adapted to the Ware placed thereon. Some can be lateral and others longitudinal or angular. Attention must be paid, however, to arrange these sti'fening-iianges so as to secure the best location for giving strength to the plate. The metal forced Out of the plate in these slots can be split in the center and both edges pressed down or cut off entirely on one side and then pressed down on the other sides, which gives wider stiifcning-anges, the more vertical the Iianges are set the greater their stiffening qualities.

One advantage found in this improved construction over the old form of construction employing rigid Wheels and axles turning in bearings on the frame is that the W reels turn freely upon the axles, and hence danger of cramping the axles and Wheels in confined positions is avoided, as when the curves Of the track are short. Hence the excessive frietion entailed thereby is avoided.

Having described our invention, what We claim as new, and desire to secure by Letters Patent, is*

l. A platform for a drier-car composed Of longitudinally and laterally perforated sheet Y metal, in combination with sLiffening-ilanges therefor composed of the metal struck from the perforations substantially as described.

2. A driercar comprising a sheet-metal platform perforated for ventilation, and stiffeniug-ribs therefor, consisting of the bentdown material from the perforations and bentover edges of the platform, in combination with suitable running-gear, therefor, substantially as described.

A platform fora drier-car, comprising a perforated sheet-metal plate, in combination with integral stifening-iianges therefor, substantially as shown and described.

4. In a drier-car, the colnbination with a sheet-metal platform composed of a plate of perforated materiahin tegral stiffenin g-iian ges therefor, composed of the bent-Over material removed from the said perforations, Wheels and wheel-axles, upon which said platform is mounted and means for securing said axles to the side flanges of the platform, substantially as described.

5. In a drier-car, the combination with an integral sheet-metal platform provided With Ventilating-openings, of stiffening-Iianges depending from the edges Of the Openings and from the sides of the platform, and Wheelaxles and Wheels, the said axles secured to said side flanges, substantially as described.

6. In a drier-car, the combination with a platform composed of integral sheet metal perforated for ventilation, stiifening-iianges depending from said platform at the sides thereof, wheels and axles underneath said platform, and means for securing the said axles to said side flanges, consisting of screwthreaded extremities to the axles, nuts and Washers, upon either side of the fianges, and sleeves separating the wheels from each other and from the inner nuts, substantially as described.

In testimony whereof We have signed our names to this specification in the presence of two subscribing Witnesses.
