FERDINAND F. WAECHTER, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO LINK-BELT COMPANY, OF CHICAGO, ILLINOIS, AND PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF ILLINOIS.
BELTCONVEYER IDLER.
Specification of Letters Patent.
Patented June 18, 1907.
Application filed NOVember 3, 1906. Serial No. 341,904.
To a/ZZ whom t may concern:
Be it known that I, FERDINAND F. WAEGH- TER, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Im rovements in Belt-Conveye'r vobjectionable on account of the wear.
By my invention I make an idler which can be readily balanced and which can be assembled without the use of separate fastenings if desired, and by means of disks which not only center the idler but also firmly secure it to the shaft. V
In the accompanying drawing Figure 1, is a longitudinal sectional View of the preferred form of my improved idler; Fig. 2, is a perspective view of one of the pressed steel ell ends; Fig. 3, is a perspective view of the disks; Figs. 4, 5, 6 and '7, are views illustrating modifications of my invention.
' A is the shaft `of any suitable length, which is usually mounted in bearings secured to the frame of the structure on which the conveyy, in mechanism is mounted.
is the idler which is secured to the shaft so as to turnwith it, this idler supports the conveying belt which may be of leather, fabthis construction a greater amount of matey rial can be conveyed by the belt.
My improved idler, as illustrated in Fig.A
1, is made in three parts, a central tubular section C of the diameter desired, and two bell shaped sections D, D. The bell shaped sections are made by plate (preferably steel), into shape, forming `the fiared body d and the head d. The head the opening. f
ressing a metallic" is reduced at d2 so that the head portion will extend int'o the tubular section C, the reduction is such that the outer surface of the bell section D will be on a line with the outer surface of the tubular sectionC, as indicated in Fig. 1.
The head d of the section Dis perforated for the passage of the shaft A, the opening being such as toallow the shaft to yneatly t E, E are pressed metal disks, one 'at each `end of the idler, and these disks have an outer flange e of the same taperas the inner surface of the bell portions D, D` and a hub flange e.
The opening inthe disks-is a trifle less than the diameter of the shaft so that when the parts of the idler are assembled the disks must be forced onto the shaft with considerable pressure in order that the disks will be firmly fixed to thegshaft and by forcing the disks into the enlarged'ends of the sections D, D the bevel fianges of the disks will be forced firmly against the inner surface of the bell ends, centering the bell sections and at the same time firmly attaching the assembled parts to the shaft. y
It will be understood that the centralsection C may be of any length desired and the ing the beltl as it passes over the pulley, but
also to provide a tapered surface for the disks E which are forced into each end of the section B.
The bell ends D may, in some instances, be made very short as illustrated in Fig. 5, when it is desired to make an abrupt flange at each end of the idler, as indicated at D', or the disks'may be shaped to form part of the flange as indicated at E2, Fig. 6.
In Fig. 7, I have shown the bell section D2 made in two parts, d, d', the part d `being in fact a fianged disk which is forced on the shaft and which supports the abutting edges `of the sections d and C, n
IOO
In some instances I may hold the disks in position after they are mounted on the shaft, by means of collars, set screws, or other devices, as an eXtra precaution, but I prefer to use the construction illustrated in Fig. 1, not only on account of its strength but also that it is readily assembled and the parts can be perfectly balanced, and the interior of the drum will be closed against the entrance of dirt and dust.
I olaimz- 1. The combination of a shaft, a tubular body portion ared at each end, ressed metallic disks each having a flange ared on the same line as the inside of the flare of the body portion and having a tubular hub confined to the shaft, substantially as described.
2. The combination in an idler, of a shaft, a central tubular section, end sections fitting in the tubular section, and disks mounted on the shaft and forcedinto the flared ends of the pressed end sections, substantially as described.
3.- The combination in an idler, of a shaft, a central tubular section, pressed metallic end sections fitting in the tubular section, and disks mounted on the shaft and forced into the flared ends of the pressed end sections, substantially as described.
4. The combination of a shaft, a tubular central section, two pressed end sections flared and having reduced portions at their inner ends, said reduced portions fitting in the ends of the central section, with dlsks mounted on the shaft and extending into the flared portions of the end sections, substantially as described. l
5. The combination of a shaft, a tubular central section, two pressed metallic end sections flared and having "perforated heads through which the shaft passes, and flanged disks mounted on the shaft, the flanges of the disks fitting within the flared portions of the end sections, substantially as described. 6. The combination of a shaft, a tubular central section, pressed metallic bell shaped end sections having perforated heads, the shaft passing through the perforations in the heads, a pressed metallic disk having a flange shaped to conform with the flare of the bell shaped end sections and having a hub flange forced onto the shaft, the disks retaining the several parts in position and securing them rigidly to the shaft, substantially as described.
In testimony whereof, I have signed my name to this specification, in the presence of two subscribingwitnesses. l
FERDINAND F. WAECHTER.
