11 Claims.
This invention relates to stop guides for use particularly in connection with lithograph presses.
The primary object of the invention is to provide a stop guide of such arrangement that the guide arms or fingers thereof may be easily and accurately adjusted Without the possibility of interfering with the timing of the stop mechanism.
A further object resides in so constructing the stop mechanism and the mounting therefor as to enable the ends of the guide shaft to be individually or selectively adjusted as the case may require without interfering with the operation of the machine nor in any way affecting the timing mechanism therefor.
With these objects in view, together with others which will appear as the description proceeds the invention consists in the novel construction, combination and arrangement of parts, all as will be described more fully hereinafter, illustrated in the drawings and particularly pointed out in the claims.
In the drawings:
Figure 1 is a fragmentary front elevation of a stop guide mechanism embodying the invention,
Figure 2 is a top plan view of a stop mechanism,
Figure 3 is an enlarged sectional view taken upon line 33 of Figure 1,
Figure 4 is a similar view taken on line 44 of Figure 1,
Figure 5 is a detailed perspective view of one end of the stop guide shaft,
Figure 6 is a sectional view taken upon line B% of Figure 1, and
Figure 7 is a sectional View taken upon line 'll of Figure 6.
The device embodying the invention is used in connection with the rotating cylinder or carrier of a lithograph press, and includes stop mechanism to limit the movement of and to hold the paper stationary momentarily above the cylinder until carried away by the latter. The invention resides generally in means whereby the supporting shaft for the guide arms may be adjusted in the line of movement of the traveling paper without in any way aifecting or disturbing, the timing mechanism for the guides.
In the drawings 8 indicates bearings at the sides of the machine and formed integral with the frame thereof, while 9 indicates the rotating cylinder directly adjacent to the side bearings.
Associated with the bearings and above the cylinder is a shaft If! having a longitudinal key way ll therein for the reception of keys 12 associated with guide arms or fingers l3; set screws M being employed to lock the keys and guide arms in proper position upon the shaft.
Each end of the shaft has connected thereto a bracket or yoke l5, pinned to the shaft ends by the wedges or keys Hi. The arms I! of the yoke or bracket embrace a flat plate or slide I8 forming a part of a trunnion l9 rockably mounted in the bearings 8. By this arrangement it is apparent that the trunnions and shaft may rotate in unison yet the shaft may be bodily adjusted laterally of the trunnions.
The plate or slide i8 is provided with a laterally disposed slot 28 through which passes a bolt or pin 2i connecting the arms of the yoke with the said slide. The slot 28 will be of sufficient length to permit of a relatively wide range of adjustment between the shaft and the trunnion.
Each of the plates or slides is provided with a lateral ofiset indicated at 22, carrying an upstanding yoke 23 in which is seated the shank 24 of a screw threaded in the adjacent portion of one of the yoke arms ii. The spaced shoulders 25 on the stem of the screw engage opposite ends of yoke 23 and thus limit movement of the screw relative to the plate. Rotation of the hand wheel 26 of the screw will therefore cause the yoke to move relative to the plate which is carried by the trunnion.
One of the plates has its oiiset portion 22 provided with a pin 21 spaced parallel with the trunnion, and the upper end of a link 28 is rotatably engaged by the said pin. The lower end of this link carries a roller 29 which engages a cam or eccentric 39 carried by the cylinder, while a second link 31 also connects with the lower end of link 28 to steady the motion of this said last mentioned link. The link 3! may be loosely connected at its opposite end with some fixed part of the machine, not shown.
In operation, the stop mechanism will be so timed that the cam or eccentric 39 will operate to raise the link 28 at the proper moment. This movement operates through pin 2i to rock the shaft upon the trunnions l9 and thus lift or swing the arms 13 out of the path of a sheet move together- Within the range permitted by the length of the slots 20, it is obvious that adjustments may be freely made without in any way disturbing the timing mechanism, as the supporting said shaft, means for moving said shaft relative to said trunnions and parallel with the direction of movement of said sheet, a cam on said cylinder, a link connected eccentrically with one of said trunnions, and a roller on said link riding on said cam.
2. A stop guide mechanism for presses, a cylinder to receive sheets, a shaft arranged above said cylinder and parallel with the axis thereof, trunnions rockingly supporting said shaft, means for adjusting said shaft on said trunnions, guide arms carried by said shaft, and means forrocking said shaft.
3. A stop guide mechanism for presses, a cylinder, a shaft arranged adjacent to and parallel with the axis of said cylinder, trunnions rockably supporting said shaft, means for adjusting said shaft in said trunnions, guides projecting from said shaft, and means for rocking said shaft.
4. A stop guide mechanism for presses, a cylinder, a shaft arranged adjacent to and parallel with the axis of said cylinder, a trunnion for each end of said shaft, a bracket and slide connection between the ends of the shaft and the respective trunnions, means for adjusting the brackets and slides relative to each other, guides projecting from said shaft, and means for rocking said shaft.
5. A stop guide mechanism for presses, a cylinder, bearings arranged adjacent to said cylinder, trunnions in said bearings disposed parallel with the axis of said cylinder, a slide on each trunnion, a shaft, a yoke at each end of said shaft engaging the slide of the adjacent trunnion, means on the yokes and slides for moving the yokes laterally of the trunnions, guide arms 7 on said shaft, and means on the cylinder for rocking said shaft.
6. A stop guide mechanism for presses, a cylinder, trunnions rockably mounted adjacent to said cylinder and parallel with the axis thereof, a shaft, a yoke at each end of said shaft embracing the adjacent trunnion, a screw member associated with each yoke and trunnion for moving the yoke laterally of the trunnion, guide arms projecting from said shaft, and means for rocking said trunnions.
'7. A stop guide mechanism for presses, 2. cylinder, a cam on said cylinder, a shaft rockably mounted above and parallel with the axis of said cylinder, guide arms depending from said shaft, a link eccentrically connected at one end with said shaft, a roller on the opposite end of said shaft riding on said cam, and means for adjusting said shaft laterally.
8. A mounting for stop guides, comprising a shaft, a trunnion for each end of said shaft, a slide on each trunnion, a yoke on each shaft end embracing the adjacent slide, a screw loosely mounted on said slide and threaded in said yoke, a screw locking said yoke and slide together, a pin on said slide spaced parallel to said trunnion, a link connected to said pin, and guide arms projecting from said shaft.
9. A stop guide for presses, a guide member disposed transverse to the travel of a sheet in said press, an oscillatory member supporting said guide member, and means for adjusting said guide member relative to said oscillatory member.
10. A stop guide for presses, a guide member disposed transverse to the travel of a sheet in said press, an oscillatory member supporting said guide member, and means associated with the guide and oscillatory member for adjusting the guide member in the line of travel of the sheet.
11. A stop guide for presses, oscillatory members at opposite sides of said press, a guide member disposed transverse to the path of travel of a sheet in said press and supported by said oscillatory members, and means for adjusting said guide member on said oscillatory members.
