HICKOK MANUFACTURING COMPANY, OF HARRISBURG, PENNSYLVANIA, A COR PORATION OF PENNSYLVANIA f coNvEYnn AND GUIDI:`
Application tiled September 21, 1927. Serial No. 220,994.
I v to provide novel and'efi'ective mechanism that will insure the sheets engaging and being directed along the guides, so that they will be in proper position to be fed into the mecha nisrn that operates upon them.
In the accompanying drawings Figure 1 is a plan view of a guide and 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, ,y
Figure 4 isa plan view of one of the directing rollers and the associated ball thereon.
In the embodiment "disclosed, the guid for the sheets is preferably in the form of an angle iron 5, having an upstanding guide flange 6 and a horizontal fiange 7. The con-` veyer for the sheets is shown as comprising endless tapes 7 Y passing around rollers 8, one of these tapes 7a'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 lefthand 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 against the upstanding flange 6 of the guide. To accomplish this there are provided a plu.- rality of directing rollers 9, which are provided with rubber or other peripheral surfaces 10 that will cause frictional engagement With the sheets. These rollers are carried by shafts 11 journaled in boxes 12 secured tothe .under side of theguide 5 and having axes of /rotation inclined-to the guide and conveyer -tapes 7 il 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 ofthe conveyer rollers .8. By reference to Figure 3, it will be noted that the sheets, 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 aretaining bar 16 that overlies the horizontal flange 7 and the rollers 9. This 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.
' By reason of this construction, it will bel evident that thev sheets as theyy are carried by the conveyer tapes 7a-will pass between the rollers 9 and the balls 18, the latter'serving to hold the sheets upon the rollers and because of the inclinationof these rollers the sheets will be moved until their edges strike against and travel alongy the outstanding guide flange 6. s Y
From the foregoing, itlis thought that the construction, operation and many advantages 0f 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, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention. Y
What I claim, is: t 4
1. In a structure of the character set forth, the combination with a guide for the sheets, of spaced conveyer tapes operating longitudinally of the guide, one of said tapes being located directly adjacent to said guide,a sheet engaging roller located between the tapes and having its axis of rotation at an inclination to the guide, a ball holder mounted on the guide and overhanging the adjacent tape and the space between the tapes, and a ball in the holderl restin on the sheets over the roller and between t e tapes.
2.. In a structure of the character set forth, the combination with a uide for the sheets comprising an angle bar aving a horizontal supporting fiange and an upstanding guide said roller having its axis of rotation disposed at an inclination to the guideange, a ball holder, and a ball inthe holder that rests onl the sheets above thevroller and alongside the 5 conveyer member.
3. In a structure of the character set forth, the combination with a guide for the sheets, comprisingV an angle bar having a horizontal supporting ange and an upstanding guide flange, of spaced conveyer tapes, one of which travels on the supporting Jlang, a sheet engag'ing roller located between'the tapes, said roller having its axis of rotation disposed at an inclination to the guide flange, a bar secured to the upstanding flange of the guide and overhane'ing the tape on the horizontal flange and the' adjacent space between the tapes, and a freely rotatable ball in the bar supported by the underlying roller.
