SPANG-ELO, OF CONCRETE, NORTH DAKOTA. I

BELT-APPLYING DEVICE.

To all whom it may concern Be it known that we, ALBERT N. SPANGELO, a subject of the King of England, residing at Darlingford, in the Province of Manitoba, Dominion of Canada, and FREDERICK O.

ISPANGELO, a citizen'of the United States, residing at Concrete, in the county of Pembina and State of North Dakota, have in vented certain new and useful Improvements in Belt-Applying Devices; and we do de clare the followingto be a full, clear, and exact description of the invention, suchas will enable others skilled in the art to which i A further object, in carrying out the above-- end, is to provide locking means whereby a movable jaw may be locked in adjusted position and to construct this means in such a manner as to allow a belt to exerta tighten ing action thereon.

Yet another object is to construct the ensistent with its proper operation.

With the above and minor objects in view, the invention resides in certain novel features of construction andcombination herein described and claimed and shown in the drawings wherein Figure 1 is a perspective View of a pulley showingthe application of the invention in applying a belt thereto; Fig. 2 is a transverse section through the rim of the pulley showing more particularly the manner in which the belt applying device is attached thereto; Fig. 3 is an enlarged section, partly in elevation and taken substantially upon the line 3 3 of Fig. 2; andFigs. 4, 5, and 6 are transverse sections taken on the lines 4-4, 5-5, and 66 of Fig. 2 respectively.

In the accompanying drawings, a pulley P is shown which as mounted upon the usual shaft S and whose rim R isto receive thereon a belt B. For the purpose of facilitataing the application of the belt B, the device, indicated broadly by the numeral 1 is provided, said device comprlsing an elongated cylindrical shank 2 having one of its ends turned laterally to provide a fixed jaw 3 having an inwardly extending nose 4 formed Specification of Letters Patent.

on its free end, while the opposite end of the shank 2 1s externally threaded as indicated at 5 and passed through the head 6 of a movable jaw member 7, abore 8 being provided through said head and equipped with in ternal screw threads interengaging with the threads 5. Forreasons to become clear, it is not necessary toform a nose upon the free end of the jaw 7 but it becomes expedient to provide a nut 9 which is likewise threaded upon the threads 5 whereby said movable jaw may be locked in its adjusted positions.

In most cases it likewise becomes expedient to provide a protecting sleeve or tube 10 formed integrally with the outer face of the nut 9, said tube encircling the threaded end of the shank 2 and thereby protectingthe .belt B against injury when being applied.

With the parts as above described, the shank 2 is positioned transversely upon the periphery of the rim It with the nose 4 contacting with one inner curved edge thereof, the movable jaw 7 is turned upon the threads 5 until said jaw contacts with the opposite edge of the rim with which the jaw 3 contacts and lastly, the nut 9 is turned upon said threads 5 and forced into binding c011- tact with the head 8 bymeans of a wrench or other suitable tool. One of the looped end portions of the belt B may now be engaged with the sleeve 10 as seen in Fig. 1 and a portion of said belt is forced, by any suitable means, onto the periphery of the rim R. The pulley P is now rotated, thus causing the belt to be engaged with the rim by the time a complete revolution of the pulley has been effected. With the belt inv proper position upon the pulley, the device 1 may be removed, thus allowing the periphery of the rim R to be unobstructed for the passage of the belt B thereof.

When the belt B is being applied as shown in Fig. 1, the tendency of the upper stretch B thereof is to rotate the sleeve 10 in a clockwise direction thereby retaining the nut 9 in contact with the head 6 and locking the latter against possible movement.

From the foregoing description, taken in connection with the accompanying drawings, it will be seen that an extremely simple device has been provided for carrying out the objects of the invention yet one which will readily perform the functions for which it is designed.

Having thus described our invention,

what we claim as new anddesire to. secure by Letters Patent is: a 1. A belt applying device comprising ,a

shank having a relatively fixed shaw on one of its end portions, its opposite end portion being threaded, a movable jaw having a bore provided with screw threads interengaged.

with the threads on said shank, a lock nut llkewlse engaged with the threads on said shank and adapted to bear against said'movable jaw to lock the same in adjusted posi-' tion, and a sleeve united at one end with f end of said shank and having a port-ionprovided with internal screw threads interengaged with the threads on saidshank, said *sleevebeingd'esigned to be turned into'b'in'dmg contactwith said movable jaw to lock the same in adjusted position.

3. A belt applying device comprising a shank having one of its end portions pm 7 Copies ofv this patent may be obtained-foifive cents each, by addressing yi ded with screw alaterally prow ectlng jaw formed integrally with the opposite. end of said shank and, having an'inwardlyje'xtending nose, "a head having a bore therein provided with screw threads interengaged with the threads on said shank, .a relatively movable jaw integrally united said head and designed to coast with the r1g1d aw for clamping the shank upon a pulley, a look nut threaded upon said shank, andbearing against said head,'and a guard sleeve integrally united atone end with said nut, said; sleeve 7 encircling the threaded end portion volisaid shank."

4; A-bel't applying device comprising a shank having a jaw at one endand a movable jaw at the other end, aguardsleeve surrounding the shank to be moved when holding" said movable jaw in adjustedfposition on 'said shank.

In testimony whereof we have hereunto set our hands in presence of twoeflbscrib ingwitnesses. I ALBERT N. SPANGELO. V r FREDERICK O. SPAN Witnesses; V Li. 7
