To all whom it may concern:

Be it known that we, Gust-AVE HANSON and Cums A. NELSON, each a citizen of the United States and a resident of East 45 Berlin, in the county of Hartford and State of Connecticut, have invented new and Improved Portable Conveyors, of which the following is a specification.

Our invention relates to the class of con- 10 veyers above mentioned, and an object of our invention, among others, is to provide a conveyer member adjustably supported and including driving means carried by said member, and the latter being so arranged to that it may be positioned for use under many and varyin conditions.

One form of evice embodying our invention and in the construction and use 0 which the objects herein set out, as well'as so others, may be attained, is illustrated in the accompanying drawings, in which- Figure 1 is a view of our improved conveyer looking from one side and shown as cut in vertical section. I a

Figure 2 is a top lan view of the same. Figure 3 (Sheet 1) is a View in side elevation on enlarged scale of a portion of our improved conve er.

Figure d (Sheet is a top view of one to end of the conveyer frame.

Figure 5 (Sheet H) is a detail view illustrating the arrangement of the guides for the conve er frame.

Figure 6 heet T) is a detail view of the motor and gear box.

Figure 7 (Sheet 1) is a side view of the same.

As its name indicates, our improved con veyer mayibe moved from place to lace, and to this end and as shown in the rawings, it embodies a base 10 in the form" of a frame with sides and ends preferably formed of angle irons secured together in any suitable manner, the whole being supported on wheels 11. In thepreterred conmruction these wheels are rotatabl mounted in frames comprising forks 12 with shanks rotatably mounted in boxes 13- arranged in thecorners of the base, this being the well known caster construction.

The supporting frame for the conveyor member comprises four corner posts it upstanding from the base and secured thereto-in any suitable nner with side rails 15 each drum and wound thcrearound and passing over sheaves 22 rotatably mounted on the base and about sheaves 23 rotatably mounted at the upper ends of the corner f posts 14:. The outer ends of each of these cables is secured to a conveyor frame 24: at such points that the latter will be supported against tipping movement.

This frame 24: comprises sides 25 preterably in the form of trusses and each comprising a top and bottom rail connected by cross ieces, said sides being preferably forme of angle iron to secure strength and rigidity. Rollers 26 are rotatably mounted on the top rails of said frame to support an endless conveyor belt 27 passing around con veyer drums 28 rotatably mounted at the ends of the conveyor frame.

The uprights 16 are properly spaced to provide guideways tor the conveyor frame,

the latter having guide studs 29 rejecting from the sides of the toprails o the conveyer frame into the space between said posts.

A r box 304s suspended as vby none of brackets 31 from "the top rails of the conveyer frame and spannin the space therebetween near the lengt wise center thereof. A. motor bed 32 comprises an integral extension from the gear box and projecting laterally therefrom support a motor 33 in an inclined position with its shaft in line with an opening through the side of the box. The motor shaft may extend into this opening or a separate shalt may be mounted in bearings therein, how

ever, whichever construction is empled,

there being a pinion 34 secur to said shaft and in mesh with a train 35 of gears and pinions mounted in Marin the box, said train oomprismga gear 36 SQ"! in the side of ilCD cured to'a shaft 37 and carrying a sprocket wheel 38 from which a chain 39 passes to a sprocket wheel 40 secured to the shaft of one of the drums 28.

The bearings 41 for one of the conveyer drums 28 may be adjustabl mounted as by means of brackets secure by bolts projecting through slots 42 at one end of the sides of the top rails of the conveyer frame v adjusting screws 43 mounted in brackets in said top rails being employed tomove the drum, or permit its movement, to tighten or loosen the conveyer belt. The motor may be supplied with a plug at the end of an electric cable 44 to convey current to said motor.

The gear box comprising a case including a support for a motor so arranged that it may be readily. connected to a system of gear mechanism inclosed within the box, and said mechanism including a driving memher, as the sprocket wheel 38, forms an important feature of our invention, as it enables a construction of the conveyer complete with its driving means embodied therein all mounted upon a single supporting frame.

The device herein illustrated and described comprises a conveyer that is extremely simple in its construction, that is selfsupported and self-driven, and that will lend itself to uses under varying conditions, as either end may be placed at any elevation desired, within the range permitted by the frame, and without changing the elevation of the opposite end.

We claim 2-- 1. A conveyer comprising a base, a-supporting frame rising from the base, a conveyer frame rigid from end to end, extending on opposite sides, and supported for vertical movement on said supporting frame and projecting beyond the supporting frame on opposite sides thereof, means for independently-liftin either end of said conveyer frame, sai lifting means being supported by said supporting frame, and a' conveyer movably mounted on said conveyer frame.

2. A conveyer comprising a base, a supporting frame rising from the base and including two upright posts spaced apart to form guideways, a conveyor frame supported for vertical movement on said supporting frame, guides extending from the conveyer frame into said guldeways, means supported by. said supporting frame for independently liftin either end of the conveyer frame, an a conveyer movably mounted on the conveyer frame.

3. A conveyer comprising a base, a supporting frame rising from the base, a conveyer frame comprising a structure rigid from end to end suspended by means of cables supported by said supporting frame,

memo? drums for said cables, the latter being arranged to independently lift either end of the conveyer frame, and means for rotating said drums.

4:. A conveyer comprising a base, a supportin frame including corner posts rising from t e base, a conveyer frame rigid from end to end suspended from said supporting frame and between the corner posts by means of cables, said conveyer frame pro- Ljecting beyond the supporting frame on opposite sides thereof, means for operating said cables to independently lift either old of the conveyer frame, and a conveyer movably mounted on the conveyer frame.
