Description
July 31, 1934 F. A. FAHRENWALD CONVEYER ROLL 'DISK ASSEMBLY Filed June 3, 1953 .40 in the furnaces when in use.
Patented .uy 31, 1934 UNITED STATES PATENT OFFICE Claims.
stand up without distortion under the high temperature of 1800 to 2000 F. to which be subjected in use.
It is further an object of the present invention to disclose a furnace conveyer roll which they may MI5 has a minimum area of contact With the supporting shaft and in which the radial portions of the rolls are formed by spaced walls which support the outer peripheral edge portion.
A still further object of the present invention '20 is to disclose a novel form of construction Whereby the rolls may be readily secured in driving relation to the furnace conveyer shafts and which permits ready replacement of the rolls.
Further objects and advantages of the present 1. improvements will be more readily apparent from the following description taken in connection with the attached drawing, in which Figure 1 is a plan view of a pair of conveyer shafts and roll assemblies, the rolls being shown 30 in section;
Figure 2 is a fragmentary longitudinal section taken on the plane indicated 2-2 in Figure 1;
Figure 3 is a broken section taken on the plane indicated 3-3 in Figure 2, and
Figure 4 is a vertical cross section of a con- Veyer roll.
The conveyer shafts 10 are constructed of a suitable alloy which will stand up Without distortion under the high temperatures existing The shafts are supported by end bearing portions 12 which extend through side Walls of the furnace and are carried by suitable bearing supports. The shafts are hollow throughout their length and the cen- 4'5 tral portions 14 are formed of larger diameter than the end portions 12. The walls of the hollow shafts 10 are relatively thin in section and suitable cored openings 16 are provided for assistance in casting and to reduce the Weight of the shafts.
At suitable spaced points along the length of the shaft, a series of radial elevations 18 are formed. As shown in Figure 1 the elevations 18 are relatively wider longitudinally of the shafts than circumferentially thereof. The elevations '55 18 are further formed with slotted openings 20 extending therethrough into communication with the interior hollow portions of the shafts. Conveyer shafts substantially as disclosed are shown in Fahrenwald Patent No. 1,872,711, of August 23, l 1932.
The conveyer rolls are generally indicated 22. Each roll has a peripheral sheet supporting Wall or tread portion 24. The wall 24 is formed integral with radial supporting walls or webs 26, which are spaced axially of the roll. In order '65 to reduce weight and assist in casting, rthe walls 26 may be provided with cored openings 28. These openings 28 are alternately disposed on opposite sides of the roll as illustrated in Figure'3. y
The hub portion of the conveyer roll is formed by a plurality of U-shaped walls 30 Which are integral with and tie together the side walls 26. These cross Walls 30 form keyways to tightly fit the elevations or keys 18 formed on the shaft. Thus the roll may be assembled on a shaft with a drive t between the elevations 18 and the cross walls or keyways 30 of the roll. In order to hold the rolls against lateral displacement, the rolls may be spot-welded to the shafts as indicated at 32.
In order to permit ready assembly or replacement of the conveyer rolls upon the shafts, the side walls 26 of the rolls are provided With aligned slots 34 intermediate the connecting cross walls U 30. These slots 34 are made somewhat larger g5 than the elevations 18 whereby a single roll may be moved longitudinally of the shaft until it is adjacent the elevations to which it is to be connected, whereupon by a partial rotation the keyy l Ways 30 of the roll will be aligned with the ele- 90 vations or keys 18. In this position the roll may be forced axially into driving relation with the shaft.
I claim:
1. A conveyer roll for furnaces having a con- Itinuous peripheral Wall and spaced side walls, said side walls being connected by separated cross walls to form the hub of said roll.
2. A conveyer roll for furnaces consisting of an L, integral casting having relatively thin walls, said roll having a peripheral work-supporting wall, axially spaced radial side Walls and circumferentially spaced cross Walls connecting said side walls forming supports and drive connections for said .1 roll. y
3. A conveyer roll for furnaces consisting of an integral casting of relatively thin wall section having a peripheral work-supporting wall, a pair l of spaced radial Webs, hub portions connecting ho 5. In combination a furnace conveyer shaft and a conveyer roll, said shaft having a plurality of radially directed keys, said roll having a plurality of integrally formed keyways tting said keys, said roll including a pair of spaced radial walls formed with slotted openings therein, adapted to freely pass over said keys when said roll is assembled on said shaft.
