o. E. KENT MANDREL Filed Mar. 22, 1921 Patented Apr. 17, 11923.
MANDREL.
Application filed March 22, 1921.
'1 '0 all whom it may concern Be it known that I, ORION E. KENT, a citizen of the United States, residing at Reed llity, in the county of Osceola, State of Michigan, have invented a new and useful Mandrel; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
The invention relates to mandrels particularly adapted for use in connection with lathes, and has for its object to provide a mandrel comprising an arbor on which is disposed frustoconically shaped sleeves having their apex ends extending towards each other and adapted to be forced into binding engagement with correspondingly shaped apertures in the hub of a pulley or any other aperture of a member desired to be mounted on the arbor.
A further object is to provide a lug carried by the arbor which lug engages a recess in one of the sleeves in such a manner that said sleeve will be locked to the hub.
With th above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set forth shown in the drawings, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.
In the drawings Figure 1 is top plan view of the mandrel.
Figure 2 is a detail perspective view of one end of the mandrel, showing the interlocked means between the arbor thereof and one of the frustoconically shaped sleeves.
Figure 3 is a top plan view of a modified form of mandrel, showing an adjusting screw for adjusting the sleeves in relation to each other.
Referring to the drawings and particularly to Figures 1 and 2, th arbor 1 is sup ported in any suitable manner on the lathe at its enlarged end 2. Slidably mounted on the arbor 1 are spaced frustoconically shaped sleeves 3, the apex ends of which sleeves ex- Serial No. 454,519.
tend towards each other and are adapted to be forced into apertures 4 of the bosses 5 of a pulley 6 when a pulley is being mounted on the mandrel. However, it is to be understood that any other work that is to be turned on the lathe may be mounted on the mandrel if so desired. One of the sleeves 3 is provided with a radially disposed notch 7, which notch receives a radially disposed lug 8 carried by the arbor 1 and by means of which notch and lug one of the sleeves 3 is secured locked to the arbor and will rotate therewith. Threaded on the end 9 of the arbor 1 is a nut 10, by means of which nut, the outer sleeve 3 is forced into binding engagement with the aperture 4 in the boss 5 of the pulley 6 and the opposite boss 5 forced into binding engagement with the notched sleeve 3, therefore it will be seen that the pulley will be securely held against rotation on the sleeves 3, and as one of the sleeves is interlocked in the arbor 1, said pulley will revolve with the arbor.
By referring to Figure 3, it will be seen that the construction is substantially the same with the exception that the nut 10 is eliminated and a threaded adjusting screw 11 extends through said sleeves 3 and is threaded in said sleeve. By rotating the adjusting screw 11 the sleeves 3 may be moved inwardly and outwardly onthe arbor 1 in relation to each other for the reason that said adjusting screw 11 is in parallel relation with the arbor 1.
It is to be understood that the parts may be made of various sizes if so desired. From the above it will be seen that a mandrel is provided which is simple in construction and one wherein parts have been reduced to a minimum whereby it will be possible to construct the device at a low cost.
The invention having been set forth what is claimed as new and useful is A mandrel comprising an arbor, frustoconically shaped sleeves slidably mounted on said arbor, one end of the arbor being provided with a cylindrical enlargement integral therewith, an inwardly extending radially disposed lug carried by the inner end of the cylindrical enlargement and disposed in a radially disposed notch in the name to this specification in the presence of 01111176! end of one of the frustoconically tWo subscribing witnesses. s aped sleeves and a nut threaded on the other end of the arbor and adapted to co- ORION EUGENE KENT 5 operate with the outer end of one of the WVitnesses:
frustoconioally shaped members. H. R. MOINTYRE,
In testimony whereof I have signed my 7 P. S. WURED.
