BELT SHIPER.

Application filed. February 11, 1921. Serial No. 444,212.

Be it known that lj Geo-in F. Ffitnmiro, a citizen of the United States.l residing at YFiorcester. in the county of Vvorcester and Stat-e of Massachusetts, have invented a new and useful Belt Shipper, of which the following is a specification.

rllhis invention relates to a belt shipper particularly designed for use with cone pulleys. rThe invention more specifically relates to that type of belt shipper in which two shipping devices co-operate, one for each cone pulley. These devices may be mechanically separate but are designed for simultaneous manual operation to produce a single desired result.

It is one object 4of my invention to provide a construction by which my improved belt shipper may be conveniently installed under widely varying conditions and, accordingly, important features of my invention relate to improved supporting and attaching devices for a belt shipper.

Another object of my invention is to provide a belt shipper so designed that the belt may be more easily guided on and ofll of the different steps of cone pulleys.

My invention further relates to improved supporting members for the belt guides and to certain other arrangements and combinations of parts which'will be hereinafter described and more particularly pointed out in theV appended claims.

AV preferred form of my invention is shown in the drawings in which Fig. l is a front elevation of my improved belt shipper applied to the head stock of a lathe;

.Referring to the drawings, I have shown my improved belt shipper in position for moving a belt 10 which connects a driving cone pulley 11 with a driven cone pulley 12 in the head stock of a lathe or other similar machine.

I wili first describe 'the upper portion of my belt shipping mechanism which used to guide the belt to the different steps of the driving cone pulley 11. This portion of my belt shipping mechanism comprises a belt guide 13 (Fig. 2) mounted on a supporting member or carriage 14 which is slidable along a guide bar 15. The guide bar 15 is preferably of rectangular cross-section and is secured at each end in supporting arms 16 (Fig. 4). rlhe arms 16 have vertical openings therein through which extend rods 1'?. the upper ends of which are secured in brackets 18.

The brackets 1S are preferably offset as shown in Fig. 1 and may each be secured to the ceiling or other supporting structure by a bolt 19. By swinging the bracket around its bolt 19 a considerable range of adjustment may be secured. lt is thus often possible to secure the brackets in place by bolts already provided for other purposes. The rods 17 are vertically adjustable in the brackets 18 and also in the arms 16 so that the elevation of the guide bar 15 may be adjusted asdesired.

Rollers 2O are provided in the arms 16 to support and guide a rope 21 secured to a depending projection 22 onthe carriage 14. The carriage is thus conveniently moved along the bar 15 by grasping one or the other of the handles 23 at the ends of the rope 21.

The carriage 14 is commonly formed as a single casting having an opening 24 loosely receiving the supporting guide bar 15. Grooved guide rolls 25 are provided in oppositely disposed pairs on 'the carriage 14 and engage opposite angles of the bar 15 as clearly shown in Fig. 9. The carriage is thus supported in a definite angular position and is freely movable upon the rolls 25, the opening 24 being large enough to clear the bar 15 as the carriage is moved on its rolls.
