Conveyer and guide

Application filed September 21, 1927. Serial No. 220,994.

The present invention relates to conveyers and guides for paper sheets, the object being to provide novel and effective mechanism that will insure the sheets engaging and being di5 rected along the guides, so that they will be in proper position to be fed into the mechanism that operates upon them·

In the accompanying drawings:

Figure 1 is a plan view of a guide and a 10 portion of the conveyer associated therewith and showing the novel sheet directing mechanism,

Figure 2 is a longitudinal sectional view on the line 2—2 of Figure 1,

Figure 3 is a cross sectional view on the line 3—3 of Figure 1,

Figure 4 is. a plan view of one of the directing rollers and the associated ball thereon.

In the embodiment disclosed, the guidi for ²⁰ the sheets is preferably in the form of an angle iron 5, having an upstanding guide flange 6 and a horizontal flange 7. The conveyer for the sheets is shown as comprising endless tapes 7^a passing around rollers 8, one ²⁵ of these tapes 7^a’having its upper or active stretch resting on the horizontal flange 7 of the guide.

It will be understood that the sheets are delivered successively on to the tapes at the left³⁰ hand end of the machine from a feeder or other suitable apparatus, and are discharged from the right-hand end. In order that the sheets may be properly positioned when delivered from the conveyer, they should be ⁸⁵ against the upstanding flange 6 of the guide. To accomplish this there are provided a plurality of directing rollers 9, which are provided with rubber or other peripheral sur₄₀ faces 10 that will cause frictional engagement with the sheets. These rollers are carried by shafts 11 journaled in boxes 12 secured to the under side of the guide 5 and having axes of rotation inclined to the guide and conveyer ₄₅ tapes 7^a. The outer ends of the shafts 11 are provided with pulleys 13, around which pass driving belts 14 operated from a pulley 15 on one of the conveyer rollers 8. By reference to Figure 3, it will be noted that the sheets, 50 as A, carried by the conveyer tapes, are engaged by the rollers 9, which are arranged beneath their path of travel.

Secured to the upstanding flange 6 of the guide 5 is a retaining bar 16 that overlies the horizontal flange 7 and the rollers 9. This 55 bar is provided with vertical openings or sockets 17 arranged over the rollers 10. In .the sockets are located bearing balls 18 that thus rest upon the rollers and on the sheets A as they pass over the same. _t । eo

By reason of this construction, it will be evident that the sheets as they are carried by the conveyer tapes 7^a will pass between the rollers 9 and the balls 18, the latter serving to hold the sheets upon the rollers and be- 65 cause of the inclination of these rollers the sheets will be moved until their edges strike against and travel along the outstandirfg guide flange 6. i

From the foregoing, it'is thought that the 70 construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art without further description, and it will be understood that various changes in the size, shape, pro- ⁷⁸portion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
