SHEET-REGISTERING MECHANISM.
Specification of Letters Patent.
Patented Jan. 24, 1922.
To all whom it may concern:
Be it known that we, CARL E. CHRISTO- PHEL, a citizen of Germany, and FRED J. EISERMAN, a citizen of the United States, both residing at Pearl River, in the county of 'Rockland and State of New York, have invented certain new and useful Improvements in Sheet-Registering Mechanism, of which the following is a specification.
This invention relates more specifically to sheet registering devices in which the registry edge of a sheet is moved into engagement with a registering surface and has for its primary objecttoprovide an improved construction, combination and arrangement of parts whereby a more perfect control of the sheets is secured. Particular objects of invention will appear in thespecification and be'pointed out in theclaims, reference being had to the accompanying drawings in which our invention is exemplifiedin a preferred embodiment. In the drawings,-
Figure 1'is a top plan view of this preferred embodiment; V
Figure 2 is a sideelevation of the same, parts being broken away and parts shown in section;
Figure 3 is a front elevation according to the line 33 of Figure 1, parts being shown in section;
Figure 4 is a section on the line 1-4, Figure 2, parts being broken away and parts shown in elevation; and
Figure 5 is a section on the line 5-5, Figure 2, parts being broken away and parts shown in section.
In the embodiment of our invention shown on the drawings, a supporting bar 1 is arranged to extend inthe direction in which thesheetis to be registered. As shown, the device is employed for side registering a sheet with respect to a side gage. Slidably mounted upon the bar 1 is an adjustable strap 2 which may be clamped to the bar 1 by means of a set screw 3 operated on a gib 4 which is in engagement with the bar 1. The strap 2 is provided with a hub or boss 5 through which extends a screw 6 which may be adjusted longitudinally by means of knurled nuts 7. Pinned to a reduced end of the screw 6 is thehub or boss 8 of a bracket 9 which is slidablymounted on the bar 1. The bracket 9 carries a depending arm 10 which terminates in a base-platell, the upper'surface of said base-plate being disposed in substantiallv the plane of feed of the sheets which are to be registered. This base-plate is provided with a groove 12 within which is reciprocably mounted a slide 13, the upper surface of said slide being in the same plane with the top surface of the base-plate 11. As shown best in Figures 1, 2 and 3, a cover 14 is arranged above the base-plate 11 andslide 13, said cover being provided with an integral bearing lug 15 which is also integral with a lever arm 16. Said cover 1 1 is provided with a slot 17 which approximately registers with the groove 12. Agrub or set screw 18 is adapted to engage the reduced end portion 19 of a stud within the bearing lug 15. Said end portion 19 of the stud is eccentric to a journal portion 20 of said stud, which is provided with an enlarged head 21 for confining a pressure roller 22 which is 'ournaled on the portion 20. It will be seen rom Figures 2 and 5 that by turning the stud in its bearing, the pressure roller 22 may be. raised or lowered with respect to the cover 1 1, the position of said cover being thereby varied with respect to the base-plate and slide whenever the pressure roller 22 is bearing against'the slide 13 or upon a sheet covering said slide. A slide register gage block 23 is arranged to determine the position of the lateral edge of the sheet for each registry movement. The lever arm 16 is keyed to a rock shaft 24 to which is also keyed a cam arm 25. Said cam arm 25 carries a cam roller 26 which travels over a profile cam 27 having a rest portion 28' for holding the pressure roller 22 and cover 14 in its extreme position away from the slide 13 and a rest portion 29 which permits said roller and cover to lie in its extreme position nearest to said slide. The rest or dwell portion 29 of the oscillatory cam is provided with an extended cam surface 29 which is adapted to momentarily lift the pressure roller 22 at the inner extreme of the slides movement so that the effective action of said'slide upon a sheet does not begin until the slide has begun its outward movement. The profile cam 27 has a hub portion 30 which is journalled on a stub shaft 31 which is secured by a set screw 31' within a bracket arm 51 of the slidable bracket 9. A miter gear 32 meshes with a second miter gear 33, the latter gear being s'plined to'an oscillatory shaft 34. As shown in Figure 2, the profile cam 27 is provided with an arcuate slot 35 and with adjustable abutments 36 and 37 at op osite ends of said slot. Referring now to igure 4, a lever arm 38 which is rigid with the miter gear 32, has its bearing hub 39 freely journaled upon the shaft 31 and is provided with a laterally projecting boss 40 which carries a pin 41, said pin being disposed within the slot 35,01. the profile cam 27. The laterallydeflected end portion 42 of the lever arm 38 carries a pin 43 upon which is journaled an anti-friction roller 44. This roller 44 is disposed between spaced pins 45 (see Figure 5) which project upwardly from the slide 13. It will be seen that by means of this construction, that a lost motion connection is provided between the slide oscillating lever and the profile cam 27.
As shown in Figure 3, the bracket 9 is provided with a curved arm 46 within which is reciprocably mounted the upper end of a spring rod 47 Said spring rod carries near its lower end a flange or collar 48 between which and the arm .46 is disposed a compression spring 49. The lower end of the spring rod 47 is pivotally mounted on a pin 50 which projects laterally from the lever arm 16. By this construction, yieldable means are provided which tend to hold the cover in its lower extreme position and at the same time press thecam roller 26 tov the profile cam 27.
From the foregoing description, it will be seen that the reciprocatory slide and the pressure roller 22 are operated in positivelytimed relations to each other. A lost motion connection of predetermined amount which may bevaried at will to meet requirements, makes it, possible to secure any desired relation between the periodical rise and fall of the pressure roller and reciprocatory movement of the slide.
