SPECIFICATION forming part of Letters Patent No. 361,236, dated April 12, 1.887. Application filed July, 1886. Serial No. 207,067. (No model.)
To all whom it may concern.-
Be it known that I, WILLIAM H. PRICE, Jr., of Cleveland, in the county of Cuyahoga and State ofOhio,havein vented certain new and useful Improvements in Platen Printing-Presses; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertainsto make and use the same.
My invention relates to improvements yin platen printing-presses, and is designed more particularly as an improvement on the devices shown in patents numbered 318,798 andI u 342,037; and it consists lin certain features of construction and in combination of parts, hereinafter described, and pointed out in the claim.
In the accompanying drawings, Figure 1 is a side elevation of my improved printingpress, portions of the press not connected with my present invention being omitted. Fig. 2is
a plan in section on the line y 1), Fig. 3, and a corresponding elevation. Fig. 3 is an elevation in section on the bent line x' x', Fig. 4, looking in the direction of the arrow. Fig. 4 is an elevation in section on theline of x x, Fig. 3. Fig. 5is a rear elevation of the lower portion of the press. 1
A represents the side arms of the bed, that above and in front form bearers A', that receive the inking-rollers and guide them down across the form.
B are movable bearers arranged on the inside of the respective bearers A', and have guide-pins b, attached near each end thereof, said guide-pins extending rearward and fitting easily in holes in the bed A?.
spring, b', the tension of which holds the bearers B in their normal position against the bed and flush with the bearers A.
In my former devices patented as aforesaid, removable bearers had inclines attached that were corresponding inclines, the latter being attached to vertical rods located between the movable bearers and the bed. Vith such construction there was but limited space at this part. The bed had to be more or less cut away or chambered to receive the vertical rods, inclines, Ste.
As an improvement I have devised the following: 'Ihe bed being provided in the usual Eearward of the bed each pin b is provided with a coilmanner with ribs A,running across the rear side thereof, holes are made in these ribs near the ends thereof and some distance rearward ofthe bed for the passage of the vertical rods C, to which latter are attached, respectively, 'inclines c, the base of the iuclines presenting downward. On top of the upper and lower ribs A, and pivoted thereto, respectively, at l,- are levers L, the ends of the levers extending from the pivotal points outward toward the adjacent side arms and resting,respective1y, against the rear ends of the pins b. The rods C -pass just at the rear of the levers L, and the inclines c are located in position on the rods to press the lever forward when the rods are elevated. The forward movement of the levers L of course pushes the pins b forward and advane-es the bearers B, and holds the inkingrollers away from the form. With my improved construction little or no change is required in the bed,exeept to drill the necessary holes. The device can therefore be readily attached to many presses now in use. The mechanismfor actuating the rods C is substantially the same as described in my former patent aforesaid, to wit: The lower ends of the rods C pass through holes in the cross-bar A4 of the arms A, and the rods above the crossbar are ,provided with adjustable collars. c', that act as stops to limit the depression of the rods, the rods ino-ving downward by gravity.
'A rock-shaft, D, is pivoted to the supportingframe E. The rock-shaft has cams or toes d, that extend respectively under the ends of the rods C for elevating the latter.
In view of reducing the initial cost and rendering the press more convenient, I have devised the following mechanism for operatin the rock-shaft D. The latter is provided with an arm, D', extending forward and upward, substantially as shown in Fig. 1. The arm M, that is a part of the impression throw-oft', and fully Vdescribed in United States Patent No. 3,18, 798, is made to extend some distance below its axis, forming an arm, P, to engage the arm D'. Ot' course the arm P could be/made separate from the arm D', if desired; but it would onlyincre'ase the cost oi' the mechanism without any material benelit accruing from lever H is moved rearward to throw on the impression throwoff, near the end of such rear- IOO such construction. When,therefore,thehand Ward movement the arm P engages the arm D and advances the movable bearers.
It is sometimes desirable to prevent only a single impression being taken, and with or without inking` the form, as the case may be. rIhe extreme throw of the impression throwoi is usually not more than one-eighth of an inch, and a smallfraetionof this distance would prevent an impression. If the hand-lever is moved until the arms P and D collide, or nearly so, an impression is prevented without advancing the movable bearers. A further slight movement ofthehand-lever advances the bearers B, in which case the form is not inked, but none of the parts are locked. A further orfull movement of the handlever locks the impression throw-omni a manner described in patent No. 318,798 aforesaid, and the lower end of the arm P passes over and engages the beveled end d of the arm D and locks the latter. The hand-lever at cach termini i'alls past the center of gravity and remains in position. This arrangement of mechanism for operating the rock-shaft D reduces the initial cost ofthe press, and is much more convenient and simple than my former device for this purpose. The arrangement is such that an operator of ordinary intelligence is not likely to make a mistake, and the different changes could be made instantaneously.
IVhat I claim is- In a platen printing-press, the combination, with movable bearer mounted on guide-pins extending rearward and springs for drawing the bearers rearward, of pivoted levers, the free ends thereof resting against the rear of the guide-pins,and vertically-moving rods withinclines attached for pushing` the guide-pins to actuate the movable bearers, substantially as set forth.
In testimony whereof I sign this speeieation,in the presence of two witnesses,this 18th day of Juno, 1.886.
