CHARLES LOOK, OF LONDON, ENGLAND;
MANUFACTURE OF AXLES OR SHAFTS.
SPECIFICATION forming part of Letters Patent No. 451,676, dated May 5, 1891.
Application filed May 24, 1890. Renewed April 3, 1891. Serial No. 387,542. (No model.)
To all whom it may concern.- Be it known that I, CHARLES LOCK, a subect of the Queen of Great Britain, residing at London, England, have invented new and useful Improvements in theManufact-ure of Railway and other Axles or Shafts, of which the following is a specification.
My invention relates to the manufacture of railway and other axles or shafts, the chief object of my said invention being to so construct an axle or shaft that should any flaw exist in the metal of which it is composed such flaw will not be able to extend and thus cause the fracture of such axle or shaft.
My said invention consists, essentially, in wrapping or coiling around a core a plate or plates of relatively-thin metal, such core and coiled plate or plates being ultimately inclosed in a suitable outer casing.
To enable my invention to befully understood, I will describe the same with reference to the accompanying drawings, in which Figure 1 is a longitudinal section of a portion of an axle or shaft constructed according to my invention, and Fig. 2 is a transverse section ofthe same. Fig. 3 shows the method of forming the crank of a crank-shaft, and Fig. 4 is a side view of the said crank.
a is the core of the axle or shaft, which core is a bar of iron, steel, or other suitable metal, and Z) is the plate coiled around the said core.
In'practice I find it advantageous to make use of a thin plate-say one-sixteenth of an inch thickfor coiling around the core, so that in case a flaw exists it will not extend far through the axle in the direction of its diameter. I prefer to apply this plate in a cold state and under great pressure, so that the convolutions will lie closely together upon the core.
0 is the casing surrounding the said coiled plate. This casing may consist of a metal tube adapted to fit tightly over the coiled plate, or it may be cast thereon or applied in any other convenient manner. The casing is advantageously made of such a thickness that suitable journals can be turned therein.
When my invention is to be applied to a crank-shaft, the webs of the crank are preferably formed substantially in the manner hereinbefore describedthat is to say, by wrapping a plate of considerable length several times around the shaft and the crank-pin, as shown in Figs. 3 and 4, in which (Z indicates the crank-shaft, e the crank-pin, and ff the webs of the crank.
In order to cause the plate of which each web is composed to firmly grip the crankshaft and the crank-pin, I advantageously compress the sides of the said web together in the manner shown most clearly in Fig. 3, and hold them in position by means of bolts 9 g by bands encircling the webs or by any other desirable means.
Although I prefer to use a continuous plate rolled around the core, I may, if desired, employ a series of concentric tubes fitting one within the other.
I am aware that it has been proposed to form shafting of layers of metal joined together by welding, brazing, soldering, and the like; but this I do not claim, as the layers in my invention are not connected or joined in any manner, but are merely held in mechanical contact.
Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is-.
1. The herein-described shaft, composed of successive layers of metal held in mechanical contact, the adjacent faces of said layers be ing totally unconnected, substantially as described.
2. The herein-described shaft, composed of a core surrounded by successive layers of metal wound upon the same and held in mechanical contact with each other and with said core, the faces of said layers being totally unconnected from each other and from said core, substantially as described.
3. A shaft composed of a core, a plate of thin metal wound compactly upon said core, and an outer casing, substantially as described.
CIIARLES LOOK.
