Jan 29, l95'7 E. H. DOERNER FEEDER RoR cREcRs AND LIRE PAPER Filed July 8. 1953 United States Patent O FEEDER FOR CHECKS AND LIKE PAPER Ernest H. Doerner, Chicago, Ill., assigner to Cummins- Chicago Corp., Chicago, Ill., a corporation of Illinois Application July 8, 1953, Serial No. 366,847
6 Claims. (Cl. 271-39) My invention is directed to the successive feeding of bank checks or like strips of paper to a machine such as an endorsing machine, for performing a printing or other operation thereon, and it has for its object a better separation of the foremost one of a pack of checks to the end that the checks will be fed singly and in rapid succession notwithstanding wide differences in the thickness, size, weight, and texture of the paper and variations in atmospheric conditions affecting the operation.
The object of the invention thus generally stated, together with other and ancillary advantages, is attained by the construction and arrangement shown by way of illustration in the accompanying drawings, in which:
Figure l is a front elevational view of the improved check feeder, with a portion in section to show a detail of construction;
Fig. 2 is a transverse sectional view taken on line 2-2 of Fig. l;
Fig. 3 is a fragmentary sectional view on an enlarged scale taken approximately on line 3-3 of Fig. 2; and
Fig. 4 is a fragmentary perspective view showing a special structural feature of the base plate, which is of importance in achieving effectual separation of the foremost check.
The feeder comprises in generala base in the form of a flat plate 7 for supporting a pack of checks with the lower edges thereof resting on the plate, a feed roller 8 mounted for rotation on a horizontal axis above the plate, and a follower 9 yieldably urging the pack of checks toward the feed roller.
The base plate 7 carries at opposite ends upright standards 10 and 10a connected by tie rods 11 and 11a disposed one above the other. One of the standards, herein the standard 10a, is made in the form of a housing for partially enclosing a driving gear element 12 and also providing bearings on opposite sides of the gear element for one end of a shaft f3 to which the gear element is lixed. The other end of the shaft carries the feed roller and is supported by a bracket ld mounted on the upper tie rod 1l.
The feed roller is preferably made of relatively soft rubber or other resilient material. It is supported in outboard relation to the bracket 14 substantially centrally of the base plate in an arrangement such that the roller is readily removable and replaceable. For supporting the roller a multi-sided supporting and driving element, herein in the form of a rectangular block 15 is journaled on the free end of the shaft, the roller being formed with a similarly shaped central hole sized to cause a frictional engagement between the roller and the block. The latter has a one-way driving connection with the shaft through the medium of a collar l fast thereon and a coiled spring 17 encircling a sleeve 1S rigid with the block and projecting axially therefrom, one end of the spring being anchored to the collar so that when the shaft is rotated in a counterclockwise direction (Fig. 2) the spring grips the shaft. This construction provides an overrunning clutch connection between the drive shaft and the feed roller 2,779,593 Patented Jan. 29, 1957 ICC so as to permit rotation of the feed roller independently of the shaft at a rate in excess of the driving speed of the shaft as is conventional in devices of this character.
The follower 9 is mounted for front to rear movement on the base plate rearwardly of the feed roller. It comprises in the present instance a substantially rectangular backer plate 19 inclined upwardly and rearwardly relative to the base plate, and a supporting roller carriage 20 coacting with the base plate to assure free movement of the follower relative to the base plate while holding the backer plate parallel to the axis of the feed roller.
The follower carriage 20 comprises, as shown, a thin central block 2l generally triangular in form, to the forward edge of which the backer plate is attached. This block carries front and rear pairs of upper guide rollers 22 and 23 with the rollers of each pair disposed closely adjacent opposite sides of the block in position for engagement with the upper surface of the base plate. A lower carriage block 24 is disposed beneath the base plate and supports two shafts 25 of substantial length (Fig. l) having two pairs of guide rollers 26 for engagement with the under side of the base plate. A spacer member 27 between the two blocks travels in a slot 2S extending in a front-to-rear direction in the base plate, and disposed at opposite ends of the spacer member are a pair of rollers 29 mounted on upright pins 30 and 31 carried by the roller block, the rollers being of a diameter somewhat less than the width of the slot. For convenience in manipulating the follower the upper triangular block of the carriage is provided with a nger piece or knob 32. p
It has been found that a substantial compaction of the checks being operated upon is desirable in effecting `the separation thereof from the pack one at a time. Accordingly, not only is provision made, as above set forth, for the free movement of the carriage, but the follower is yieldably urged toward the feed roller by means of a contractile spring 33 having one end anchored to the lower carriage block 24 and the other end to an angular bracket 3d depending from the base plate at the forward edge thereof. As shown, the bracket 34 is secured to a bar 35 rigidly attached to the underside of the base plate.
As above indicated, the backer plate of the follower is inclined upwardly and rearwardly from the base plate, an angle of sixty-tive degrees from the face of the plate having been found preferable. The roller is positioned immediately above the base plate for engagement with the lower central portion of the foremost one of a pack of checks resting against the backer plate. Above and somewhat rearwardly of the feed roller the pack is sustained by a pressure element preferably in the form of a free ruiming roller 36 which is conveniently mounted on the upper tie rod l1. By this arrangement frictional resistance to the feeding of the foremost check by the feed roller is minimized.
.For guiding the ends of the checks a pair of plates 37 and 33 are provided. These plates are adjustably mounted on the lower tie rod 11a. For this purpose, each plate has rigid therewith a collar 39 for frictionally holding the platesin adjusted positions lengthwise of the tie rod.
With the feed roller driven in a counterclockwise direction (Fig. 2) and a pack of checks P yieldably urged forwardly by the follower spring, the foremost one of the checks is engaged by the feed roller and advanced thereby with the lower edge of the check sliding along the upper smooth face of the base plate. As shown, the roller is preferably provided with equidistantly spaced longitudinal ribs or teeth 4t).
The backer plate 19 of the follower is preferably provided with a strip of friction cloth 41 in accordance with conventional practice. This strip may be conveniently attached to the backer plate by means of snap fasteners 42, the backer plate being provided with an elongated slot 43 for receiving the upper edge of the strip. To provide clearance for the said roller after the pack of checks has been removed from thepface of the follower, the backer 'plate is `prefe'ra-bl`y 'provided with a notch 44 in its lower edge. This prevents unnecessary wear on the feed roller.
As rst above indicated, 'my 'invention is especially directed 'to the consistent and uniform separation of the foremost check from the next Succeeding check, especially when these two checks are relatively thin. In general, this is achieved through a novel cooperative rela- "tionship between vthe feed roller and the face plate.
s shown in Figs. l and 2 the base plate provides a srnoothbearing -surface upon which the lower edges of a pack of checks rest in an angular position determined by the inclination of the follower hacker plate 19. Beneath the rol-ler the base plate is cut away to form a generally rectangular notch having the edges '45 spaced from the opposite ends lof the feed roller, and a rear edge 46 disposedrearwardly lof a vertical plane passing through the axis, of the forward roller. The notch is open at its forward e'nd and preferably has a closed bottom wall 47 'formed in 'the 'present instance by one leg of the angular `braczket 3 4, so as to form a shallow recess or cavity. The side edges of the recess define shoulders 45 adjacent the ends of the roller, about which the checks are bent by the roller. Also, the bottom wall 47 of the cavity is disposed closely adjacent the under side of the feed roller with the result that double reverse bends 48 are formed in the paper at each opposite side of the feed roller, as :shown clearly in Fig. 3. Such double reverse bends occurring at lines spaced laterally from one another and extending longitudinally of the check, lend stiffness t each check as it is advanced by the feed roller, which is important, particularly in the case of very thin paper. ladditionally, the paper is more effectually engaged by the lower corners of the feed roller formed in the present instance by the ends of the ribs o1' teeth 4t?.
The rear edge of the recess or cavity forms a sharp shoulder 46 extending transversely of the path of travel of the checks. The position of this shoulder with respect to the roller is such that the shoulder coacts with the roller so as to tend to block the passage of more than one check at a time in the cases of thicker checks, which may b e as thick as .06S inch.
l On the other hand, the aforesaid spacing of the shoulder 46`may in some instances be sufficient to permit the simultaneous passage of two of the thinner checks, which may be on the order of .003 inch. To assist in the separation of the foremost of two such thin checks, I provide one ormore retarding surfaces engageable by the lowermost of these two checks, for the purpose of holding it back while the upper or first check is being advanced by the roller. In the present instance such a retarding surface is formed by knurling or roughening the bottom of the cavity, but it may if desired be faced with any suitable friction material.
It will thus be seen that in addition to forming the sharp double reverse `bends 48 extending in a direction parallel with the 'path of travel of the checks, the portion intermediate such bends is depressed to form a downwardly offset 'lip vforenga} 'z,"err`1ei1t with the friction surface.
Because yof the use of a feed roller of rubber or other yieldable material, it is of course contemplated that the feed roller will become worn and thus increase the spacing ythereof with 'respect to the shoulders 45 at opposite 'sides of the roller and the shoulder 46 transversely of the roller, 'as well as to the bottom of the recess. It has been found, however, that by the construction and arrangement employed substantial variations in spacing due to wear are permissible. It has been found, for example, t'liat'satisfactory resultsare obtained in a feeder in which: 21) the roller, having an initial diameter of 1 .425 inches, is positioned centrally between the shoulders 45 ofthe ecesswith aspacing of approximately y .025 inchbetweeu Such Vsho'lllle'rs and the ends of the roller; (I1) the transverse shoulder 46 has an initial spacing from the arcuate path of travel of the feed roller of .008 inch, with an allowable increase of .006 inch, indicating replacement of the roller when the spacing exceeds .O14 inch; and (c) an initial spacing of the retarding surface 47 forming the bottom of the recess from the arcuate path of travel of the roller of .004 inch, the permissible increase in this spacing due to wear of the roller being .O10 inch.
In actual practice the checks vary substantiallyin thickness. Thus, above indicated, they range from very thin paper, 'on the order vof .003 inch, to relatively heavy paper or thin cardboard on the order of .008 inch. It will be observed in this connection thatthe initial spacing of the roller from the bottom of the recess is considerably less than the thickness of the heavier or thicker checks. This is not objectionable in view of the fact that the roller is made of relatively soft rubber or other yieldable material. l
In general, the 'position of the transverse control shoulder 46 is such that in cooperation with the roller it tends to block the passage beyond the shoulder of more than one check at a time, but in the event of the passage of two checks at one time, the lowerniost one of these checks will engage with the knurled surface and thus its Inovement will be retarded until the upp'er check has been removed. p d
