PRINTER/S APPLIANCE.

Specification of Letters Patent.

Patented June 13, ieie.

Application filed September 9, 1915. Serial No. 49,818.

To all whom it may concern:

Be it known that I, ELMER'M. COBB, a citizen of the United States, and resident of South Portland, county of Cumberland, State of Maine, have invented an Improvement in Printers Appliances, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts in each of the several views.

This invention relates to a printers appliance particularly designed and adapted for use in job printing offices for engaging and releasing the clamp which holds the pad or backing to the platen.

More especially the present appliance is formed and adapted for use with a job print- I ing press of the well known Chandler & Price type or the like to engage the tympan ball at the top and bottom of the inclined platen in this type of press.

The invention will be better understood from the following description taken in connection with the accompanying drawings and will be thereafter pointed out in the appended claims.

Referred to the drawings: Figure 1 is a front elevation somewhat in perspective showing my improved appliance; Fig. 2 is an edge view thereof; and Fig. 3 isvan elevation showing the use of the device in op erating the tympan hail of a platen.

The present appliance consists in a head 10 preferably oblong and generally rectangular with flat side faces 11, 12, and somewhat convexed ends 13, 145, though this particular. form of head is not essential to the carrying out of the principles of the invention. From this head a handle 15 projects in a direction generally parallel to the lateral faces of the head, particularly the front face 12 which is the operative portion of the device for engaging the part to be operated. The outer end of the handle 15 may be formed with a wrench head 16 and the convexed end'13, 14, of the head may be used as hammer heads adapting the device to be used for hammering, though these are merely incidental attributes, and not essential to the practice of the invention. In accordance with my invention I form in the front flat face 12 of the head 10, diagonal recesses or grooves 17, 18 extending as shown from diagonally opposite corners of the head and intersecting centrally. These grooves are formed with rectangular shoulders at their sides and are each of a size to receive and fit the tympan bail to move the same by engagement thereof with the shoulders or ledges at the sides of said grooves. It will be understood that the platen to the upper and lower sides of which the tympan bail is attached, is inclined with its faces extending diagonally downward away from the operator. Thus in using the appliance for engaging the tympan bail, as to release the same, when the bail at the top is to be engaged, the device is applied to the same with the groove 18 engaging the bail, and with this engagement the handle 15 will project upward substantially upright, and convenient to the hand of the operator. When the tympan bail at the bottom or lower inclined side of the platen is to be engaged, the device is applied thereto with the groove 17 fitted to the same, which will result in the handle 15 projecting upward and outward in convenient position for the operator. It will be further understood that while the handle 15 thus projects up in a convenient direction for the hand of the operator as he stands back of the platen, with the grooves 17, 18 thus selectively engaged as described with the tympan bail at top and bottom of the platen, should it be attempted to engage the same? groove with the tympan bail in both positions, it would inevitably cause projection of the handle in an awkward or impossible direction in one or both cases. It will of course be understood that the direction of the two diagonal grooves 17,

18, will be so disposed that the handle will project to the most convenient angle for the hand of the operator in each case. It is preferable to form both these diagonal grooves 17 18 in the same face of the head of the appliance, since thereby metal stock is economized and the device can be made at the same time strong, light and convenient to operate. In Fig. 3 a printing press platen is indicated at P, this platen being usually set at an incline as in the Chandler and Price type of press with the side at the right of said figure inclined upward. The tympan bail B at the lower edge of the platen is here engaged with the groove 17 of the device while the bail B at the upper edge of the platen will be engaged by the groove 18, the handle 15 in each case being presented at a convenient angle for opera tion. o

"and not restrictive, reference being had tothe appended claims rather than to the foregoing description to indicate the scope of the invention; v

Havingd'escribed my invention, what I claim as new and desireto secure by Letters Patent is: r

l. A printers appliance, comprising a head having two grooves in a face thereof extending at an angle to each other, and a handle projecting from said head andeX-' tending in general parallelism with the plane of said grooves, one of said grooves being adapted to engage a tympan bail at the .bottom of theplaten and the other at the top of the platen with the handle in each case pro,- jecting to a'point convenient for thejoperator;

2. A printers appliance, comprising a head having two groovesformed in a face thereof'at an angle to each other and inter-.

secting, and a handle projecting from said head'in general parallelism with theplane of said grooves, said grooves being formed with straight shoulders at their sides and of a size to fit a tympan bail, one of said grooves being adapted to engage a tympan bail at the bottom of a platen and the other groove to engage a tympan bail at the top of a platen with said handle in each case projecting to'a point convenient for the operator.

3; A printers appliance, comprising a flat, oblong and generally rectangular head with intersecting grooves" extending from ELMER M. COBB.
