ADJUSTABLE ROLLER BRACE FOR SHAKER CONVEYERS Filed June 29, 1937 ATTORNEY Patented Dec. 27, 1938 RElSMlEg I EEB l3 i954 UNITED STATES ADJUSTABLE ROLLER BRACE FOB, SHAKER CONVEYERS Luther E. Jarrett, Elkridge, W. Va.

Application June 29, 1937, Serial No. 151,023

r 1 Claim.

This invention relates to braces or supports for shaker conveyers and has for the primary object the provision of a device of this character which may be readily set up and adjusted to a 5 ceiling and flooring of a room and which will efiiciently maintain a conveyer in proper position and permit raising and lowering of said conveyer and the leveling thereof.

With these and other objects in view, this in- 10 vention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of my inven- 15 tion, reference is to be had to the following description and accompanying drawing, in which Figure l is a top plan view illustrating a brace constructed in accordance with the present invention and having associated therewith a shaker 20 conveyer. I

Figure 2 is a sectional View taken on the line 2-2 of Figure 1.

Figure 3 is a sectional view taken on the line 3-3 of Figure 2.

2 Referring in detail to the drawing, thenumeral l indicates a fragmentary portion of a shaker conveyer having secured to opposite sides thereof channeled members 2 which members are connected by braces 3.

30 Arranged at opposite sides of the conveyer I are vertically arranged supporting members 4 each constructed of telescopic sections 5 and 6. The section 5 is free to slide within the section 6 but is held against rotation relative to the 35 section 6 by a pin 1 fitting in a groove 8 thereof. A base 9 is formed on the section 6 and a head if) is formed on the section 5. The base 9'is adapted to rest on the flooring of a room while the head I0 is adapted to be adjusted into engagement with the ceiling of a room. Feed threads II and I2 are formed on the sections and 6. Journaled on the upper end of the section 6 and meshing with the feed threads H is 45 a feed nut l3 having a hand wheel l4. By rotating the hand wheel It in opposite directions the section 5 can be adjusted inwardly and outwardly of the section 6. A feed nut l5 meshes with the feed threads I2 of the section 6 and is provided with a hand wheel 16.

The feed nuts l5 have grooves to receive split clamps IT. The feed nuts I5 are free to rotate v in the clamps ll and formed on the latter are 6 apertured extensions l8 to receive pivot pins [9. The pivot pins H) are carried by stub shafts 20 and which are connected by a brace 2| extending under the conveyer. The stub shafts have journaled thereon rollers 22 which engage in the channeled members 2. The pivot pins l9 have heads and slots, the latter receiving removable pins 23 secured to the stub shafts by flexible elements 2a.

A device of the character described may be readily set up within a room by adjusting the sections 5 and 6 relative to each other to bring the bases and heads in engagement with the floor and ceiling of the room. This adjustment is easily accomplished by the rotation of the hand wheels I l. The supporting members 4 thus arranged effectively support the conveyer, the latter capable of having relative movement thereto by the rollers engaging the channeled members. Further, the conveyer may be leveled by 25 adjusting the feed nuts E5 on the section 6 either in an upward or downward direction. The stub shafts 20 may be readily detached from the feed nuts I5 when desiring to remove the conveyer from the support.

Having described the invention, I claim:

A device of the character set forth comprising vertically arranged supporting members, a conveyer located to travel between said members, channeled members secured on opposite sides of the conveyer and rigidly connected with each other, said members having feed threads, feed nuts threaded on said members, collars journaled on said feed nuts and disposed horizontally, stub shafts pivotally and detachably connected to said collars, means rigidly connecting said stub shafts in oppositely disposed pairs, and rollers journaled on the stub shafts and engaging in the channeled members whereby the conveyer is free to slide relative to the supporting members and may be leveled and tilted relative to a horizontal plane by adjusting the feed nuts on said members.
