BELT-HOLDER.

SPECIFICATION forming part of Letters Patent No. 643,799, dated February 20, 1900. Application filed April 8, 1899. Serial No. 712,334. (No model.)

To ctZZ whom it may concern:

Be it known that I, FRANK E. LEVANSELER, a citizen of the United States, residing at the city of Sturgis, in the county of St. Joseph and State of Michigan, have invented certain new and useful Improvements in Belt-Holders, of which the following is a specification.

This invention relates to improvements in belt-holders. It is in some respects an improvement on the structure appearing in my Patent No. 565,473, dated August 11, 1896, and in other respects it is distinct and separate therefrom.

One object of this invention is to provide an efficient and satisfactory belt-holder for use on a line-shaft or other driving-shaft which can be efliciently and satisfactorily used in that relation and be efficiently and easily operated from any distance desired.

A further object is to simplify structures of this class and relieve the wear and tear on the belt in shifting it to and from the beltholder.

Another object is to provide a belt-holder in such relation that when it is in use. all strain is relieved from the shaft.

Another object is to provide a belt-holder which may be placed in position without removing the shaft from its bearings or disturbing other pulleys upon the shaft.

Further obj ectswill definitely appear in the detailed description to follow.

I accomplish these objects of my invention by the devices, means, and mechanisms described in this specification.

The invention is fully illustrated in the accompanying drawings, forming a part of this specification, in which- Figure 1 is a detail sectional elevation of my improved device, taken on a line corresponding to line 1 1 of Fig. 2, the shifting-lever and rock-shaft being shown in broken sections. Fig. 2 is a detail elevational view taken from the right side of Fig. 1. Fig. 3 is a sectional view taken on line 2 2 of Fig. 1. Fig. 4 is a detail sectional view of the shifting-lever G and its connections and the removable section of rim B and frame 0, taken on line corresponding to line 4 4 of Fig. 1. Fig. 5 is a sectional View taken on line 5 5 of Fig. 1, showing removable sections in detail.

All the sectional views are taken looking in the direction of the little arrows at the ends of the section-lines, and similar letters of ref erence refer to similar parts throughout the several views.

Referring to the lettered parts of the drawings, A is a line-shaft, which is supported by suitagole hangers. (Not shown in this connection.

B is the driving pulley on the shaft A, which is secured thereto by any well-known suitable means.

O is the circular frame, that carries the loose pulley or band B. The periphery of the band B is tapering, being substantially a portion of a cone, the larger side of which is nearest the pulley B. Interposed between the band B and the frame O are antifriction-rollers P, which fit into suitable races in the parts and permit the band B to revolve with very little friction and in such a manner as to require little or no lubrication. Balls or other forms of rollers with the parts suitably adapted might be substituted for the cylindrical rollers which here appear. Secured to the side of frame 0 are the ears I I, which contain suitable perforations. A suitable rod or hanger D is secured to the joists L above and projects down near the side of the line or driving shaft A. Secured to the hanger D by suitable clips E E are pins which extend par allel with the line-shaft A through the ears I I hereinbefore referred to. It will be observed that this structure will permit the sliding of the frame 0 upon the pins 1, so that the band B can be brought in contact with the pulley B or be slightly separated therefrom. This movement is effected by means of the lever G, which is pivoted to the frame C at a, the short end G of which strikes against a collar H, which is secured to the line -shaft A. This lever is actuated from the belt-shipper. The belt-shipper consists of rock-shafts J J, to which are secured arms J J, which are pivotally connected together at their lower ends by the rod or bar K. On the rod or bar K is secured a-finger or arm m, which projects across the path of the belt N, which delivers the power from the pulley. The lever G is in position to be acted upon by the arm J at the opposite end and protionary, owing jectszinside the same. An operating-lever M is connected at a convenient point to either the rock-shaft J or J, or the connections may be further extendedby rock-shafts or hellcranks to any point desired. One of the arms J might be extended to form an operatinglever, or the lever might be attached to any movable part.

In order to put the belt-holder in position without removing the shaft from bearings, frame 0 and rim B are formed in sections. (See Figs. 4 and 5.) The screws being removed releases the outer sections T T of rim B, when the inner section '1", held in position by the pins it u, may be easilyremoved. The removable sections of frame 0 are constructed on the same principle as rim B. The outer sections S S being removed releases the inner section S. (See Fig. 4.)

Having thus described my improved beltholder, I will briefly indicate its operation. The belt N being on the pulley B, as indicated in Fig. 1, and it being desired to move the same onto the belt-holder, the lever M is pressed toward the left, as it appears in Fig. 2, and this carries the arm on against the belt and shifts it onto the rim B or the belt-holder, which also moves the rim B out of contact with the pulley B, and the belt then rests on the belt-holder and becomes immediately stato the fact that no power is imparted to it. When it is desired to throw the belt N onto the pulley B, the motion of the lever M is reversed, and this carries the arm J against the lever G, which forces the frame 0 toward the pulley B and brings the rim B into contact with the pulley B. As soon as this contact occurs the friction from the pulley B causes the rim B to revolve, which, acting under the well-known influence of pulleys and belts, causes the belt to climb to the highest point of the rim B, and hence onto the pulley B, which is slightly larger than the rim B at its largest point. This shifting of the belt, it will be observed, is effected without striking the belt with any beltshipper, and it will thus be observed that by utilizing this device there is little or no wear 011 the belt itself. It will also be observed that the belt-holder does not come in contact with the shaft at any point and that therefore there is no tendency to throw the shaft out of alinement or cause it to sag.

Having thus described my improved beltholder, I desire to say that, as here shown, it possesses great merit. I am aware that it can be greatly varied in its details without departing from my invention. Instead of the holder being supported to slide, as here shown, it might be supported to swing, as shown in my former patent, or it might be otherwise supported independent of the shaft. It will readily be understood that other forms of removable sections might be substituted for the one shown and be greatly varied without departing from my invention, as an ordinary tongue and groove on the piece T and adjacent parts might be used instead of the pins it or might be dispensed with entirely; but the structure shown is preferred by me as being easy to take apart and very strong.

My improved belt-holder is also adapted to be used on shafts which are supported on post-hangers or pillow-blocks, it only requiringdifierent connections tosupport theholder independent of the shaft. In this connection I desire to state that while I prefer the lever G pivoted on the frame C I am aware it could be pivoted to an independent support and act upon the holder and secure the same result.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a belt-holder the combination of a line-shaft A, having a pulley B, thereon; a hanger or other support D, having pins I, parallel with the shaft; a frame 0, adapted to move in the direction of the shaft; a rim B, conical in form, the large end of which is toward the pulley B, supported by said frame 0; antifriction-rollers P, in suitable races; the belt-shifter consisting of rock-shafts J, J, having arms J; pivotally connected by the rod; the arm m, to strike against the belt to ship the belt; a lever to swing the same to ship the belt; a lever G, pivoted on the frame 0, and a collar H, on the line-shaft A, against which the said lever G, strikes to carry the belt-holder so the rim B, will contact with the pulley B, for the purpose specified.

2. The combination in a belt-holder of a line-shaftA, with a pulley B, thereon; a movable frame 0 a rim B, the periphery of which is conical in form from edge to edge, which is supported to revolve on the frame 0; a beltshipper to ship the belt from the pulley to the rim and means for moving the belt-holder so that the rim B, will contact with the pulley B, the contacting edge of which is beveled to the point of contact with the periphery of the rim B, all coacting for the purpose specified.

3. The combination in a belt-holder of a line-shaft A, with a pulley B thereon; a movable frame C; a rim B, conical in form supported to revolve on the frame 0; both the frame and rim being formed with removable sections; a belt-shipper to ship the belt from the pulley to the rim and means for-moving the belt-holder so that the rim B, will contact with the pulley B, all coacting for the purpose specified.
