THOMAS S. PATTERSON, OF BOSEMONT, PENNSYLVANIA, ASSIGNOR TO THE OIL AND WASTE SAVING MACHINE COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A COR- PORATION OF PENNSYLVANIA.
TI-IRUST-BEARING.
Specification of Letters Patent.
Patented Mar. 21, 1911.
To all whom it may concern:
Be it known that I, THOMAS S. PATTERSON, a subject of the King of Great Britain and Ireland, residing in Rosemont, Pennsylvania, have invented certain Improvements in Thrust-Bearings, of which the following is a specification.
My invention relates to certain improvements in bearings especially designed for use in centrifugal separators or washers driven by a turbine motor, and one object of my invention is to provide improved means for supporting the basket of the device without employing a step hearing.
In the accompanying drawings :Fignre 1, is a vertical sectional view of a centrifugal machine illustrating my invention; Fig. 2, is a perspective view of the end of the driving shaft; and Fig. 3, is an enlarged section illustrating the coupling between the driving shaft and the basket shaft of the machine.
A is the base of the machine.
B is a casing mounted upon the base and provided with a cover 6.
A is a bearing extending partly into the casing B and into the base A. In this hearing is mounted a vertical shaft E carrying at its upper end the basket D. The hub (Z of the basket is preferably made in the manner shown in Fig. 1, having a perforated wall 03.
d is a screen suitably mounted at the pe riphery of the basket.
F is a turbine engine casing mounted in the lower portion of the base A and this casing has a bearing f for a vertical driving shaft C to which is secured the wheel C of the turbine engine.
The shaft C is suspended from a ball hearing G mounted in the'lower portion of the bearing A, thus dispensing with a step hearing for the shaft O in the casing F; this obviates one of the difficulties in this class of apparatus.
The anti-friction bearing Gr in the present instance consists of two disks 9 g and a series of balls or rollers g mounted in a carriage g situated between the two disks. In the upper disk 9 is a seat 9 for the enlarged end 0 of the shaft C, forming in fact a ball and socket joint. The shaft is suspended from this disk and is held laterally by the bearing f as well as by a bearing in the cap a which retains the ball bearing in place.
The upper end of the shaft C is rounded as at 0 and the end of the shaft E is concaved to fit the rounded end of the shaft C and also has a transverse slot 6 into which extends the key 6, which is secured in a slot in the head of the shaft C, preferably by a transverse pin 6 Thus the shaft E rests upon the head of the shaft C, which in turn is carried by the ball bearing G, and the shaft E is driven by the shaft C through the key e. The shaft E is perfectly free with the exception that it must rotate with the shaft C and it can be readily removed with the basket, if desired, without disturbing the driving shaft C.
I claim 1. The combination of a driving shaft having an enlarged and rounded head, a ball bearing consisting of upper and lower plates and intervening balls, a socket in the upper plate adapted to receive the enlarged and rounded head of the said driving shaft, a driven shaft mounted above the said driving shaft and concaved at its lower end to fit over the rounded head of the driving shaft, a key secured to the driving shaft, the driven shaft having a slot in which the key extends, and means for turning the driving shaft.
2. The combination of a tubular supporting structure; two plates within said struc ture having anti-friction elements between them; a downwardly extending shaft section supported on and extending through said two plates; a shaft supported on and extending upwardly from said shaft section; with driving means connected to the downwardly extending shaft section below said bearing plates; there being between the abutting ends of said shaft and shaft section a connection including a rounded head on one of said members and a socket for said head on the other member; with a key positively connecting the head and the socket.
3. The combination of a tubular supporting structure; two plates mounted at the lower end thereof; a shaft terminating adj a- In testimony whereof, I have signed my cent to one of said plates; balls between the 9 name to this specification, in the presence of 10 plates; the lower end of the shaft and one I two subscribing Witnesses.
of the lates bein rovided with rounded recesses a shaft sgctiion projecting through THOMAS PATTERSOI\' the plates and having a head fitting said re- WVitnesses:
cesses; with means for operatively coupling WM. E. SHUPE,
said shaft and the shaft section. WM. A. BARR.
Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents, Washington, D. G.
