MOVABLE AND ADJUSTABLE BEARE R FOR PLATEN PRINTlNG-PRESSES.
SPECIFICATION forming part of Letters Patent No. 595,991, dated December 21, 1897. Application filed July 22,1897. Serial No. 545,550. on. model.)
To all whom it may concern.-
Be it known that I, FRANK A. BURNHAM, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new anduseful Improvements in ,Movable and Adjustable Bearers for Platen Printing-Presses; and I do declare that the following is a full, clear, and exact description of the invention,
which will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to platen printingpresses; and the invention consists in movable and adjustable bearers for the ink-rollers and mechanism connected with the back shaft, whereby when for any reason the throwofi mechanism is operated to prevent an impression the said bearers will be carried forward, so as to prevent the ink-rollers from 2o inking the type-form, and whereby said bearers may be set or adjusted to regulate the depth of contact or relation of the inkrollers to the type-form, all substantially as shown and described,and particularly pointed out in the claims.
In the accompanying drawings, Figure 1 is a side elevation of a press containing my improved mechanism. Fig. 2 is a plan View of the press on line ac 00, Fig. 1. Fig. 3 is a crosssection on line 3 3, Fig. 2, showing the beareroperating mechanism in impression and inking position, as in Fig. 1. Fig. 4 is a crosssection of Fig. 2 on line 3 3, the same as Fig. 3, but showing the bearer-operating mechan- 3 5 ism as it appears when the impression is thrown off and the inking-rolls are out of contact. Fig. 5 is an enlarged elevation and section on line 3 3, Fig. 2, of the back shaft and my novel mechanism for setting the ink- 0 rolls at a suitable working depth. Fig. 6 is a sectional plan View of said mechanism.
A represents the frame of the press, and B the bed thereof.
C is the back shaft, which extends laterally pressman throws the ink-rollers out of contact with the type-form and the said form out of impression at the same operation. To these ends'the lever F is operatively connected with shaft 0' through two gear-segments G and H, supported on the side and foot of the press and meshed to be operated together. A crank-arm 2, rigid with segment G, and alink 3, connecting said arm with lever F, serves tooperate said segment, and a bar or rod or the like, K, connects segment H with a short arm 4, rigid with shaft C. Lever F is suitably pivoted on frame A, with throw enough to easily and quickly operate segment G, and thence the shaft 0, as the demands of the press may require. The shaft C has thus imparted a rotary movement, and the connecting-rod E is supported thereon by a wrist-pin eccentric to the axis of the shaft, so that when said shaft is rotated the 7c impression throw-off is effected, as fully set forth in a concurrent application, Serial No. 645,551, in which the throw-off mechanism is claimed as a distinct and separate invention.
Referring now more especially to Fig. 2, we see the mechanism for keeping the ink-rolls out of inking relation to the type-form, comprising two sidebearer plates or parts L, alike in construction and function and having their front bearing edges or surfaces widened some what by lateral flanges, which overlap the fixed or stationary bearers 5 of the press. These plates extend rearward toward shaft C in form substantially as seen in Fig. 5, where they are engaged by a transverse rod N, which projects at its ends through slots 6 in the bed into said plates.
On shaft C are sleeved two corresponding hubs M, made rigid with said shaft by setscrews or anysuitable means and having eco centric-bearings S on which ride the collars P, fitting closely on said bearings. These collars have each an inwardly-projecting portion with circular bearings 9, in which the rod 1 N is supported through hubs R, fixed rigidly 5 on said rod and having each an eccentric portion 10, engaged in said bearings 9. Hence when shaft C is rotated the eccentrics 8 have throw enough to carry the rod N and bearerplates L a sufficient distance to keep the ink- IOO rollers S out of contact with-the type-form T, and when rotated to the opposite position said parts are of course restored again to Working relation, as seen in Fig. 2. The difference of position effected through eccentrics 8 is shown in Figs. 3 and 4, Fig. 3 showing Working position and Fig. 4 idle position.
Now as a further feature of invention I have devised means for fixing the Working position of the ink-rollers. These rollers are liable to operate with varying effects, even when relatively under the same adjustment, owing to differences in the consistency or condition of the ink or of the roller itself, so as to require adjustment on that account, and then again rollers will grad n all y shrink during use and require adjustment for this reason. Therefore to provide for these contingencies I have fashioned the hubs R not only with the eccentric extensions 10, but with means to rotate said hubs in their bearings, consisting in a segmentally-slotted flange 12 on each of said hubs and a set-screw 14, engaged through the slot in said flange to fix the hub in any adjusted position. The rod N turns with the hubs R in the construction here shown, but this is not necessary. Thus the bearer-plates may be set or moved to any needed position independently of the operations of shaft C, but When once set the other operations are the same as if this special adjustment had not been made.
hat I claim is 1. The bed of the press and the bearerplates supported movably at the sides thereof, a member engaging said plates, the back shaft and eccentric-bearings thereon and connections arranged to engage said member and operate said plates, substantially as described.
2. The bed of the press and the fixed bearers for the ink-rolls, movable bearer-plates extending in front of said fixed plates and mechanism to adjust said movable plates comprising eccentrics, substantially as described.
3. Thebed of the press and the movable bearer-plates thereon, the transverse rod engaging said plates and eccentrics on said rod and bearings to set the plates in working position, substantially as described.
4c. The back shaft and means to rotate the same, in combination with the bearer-plates and means to operate said plates comprising eccentrics on said shaft, a rod engaging said plates, and collars on said eccentrics constructed and arranged toen gage said rod, sub stantially as described.
\Vitness my hand to the foregoing specification this 8th day of July, 1897.
