7 To all whom it may concern:

Be it known that I, GEORGE DUNCANSON, Jr., a citizen of the United States, and a resident of Jersey City, in the county of Hudson and State of New Jersey; have invented a new and Improved Printers Quoin, of which the following is a full, clear, and exact description.

The present invention relates to new and useful improvements in printers furniture, and it pertains more particularly to devices of this character known as printers quoins.

It is one of the primary objects of the present invention to so construct a printers quoin that the two members constituting the quoin will be positively guided. in their movements relatively to each other during the operation thereof,

It is a further object of the invention to provide means for maintaining the two members against relative movement when they have been set in operative position.

It is a still further object of the invention to obtain the heretofore mentioned advantages in printers quoins without altering the construction of the engaging surfaces of the two members serving to make up a quoin, thus rendering them capable of use with chases or frames of ordinary construction.

With the above and other objects in view, reference is had to the accompanying drawings, in which- Figure 1 is a plan view partly broken away of a device constructed in accordance with the present invention;

Fig. 2 is a side elevation, partly in section, of the device in its closed position;

Fig. 3 is a similar view of the device in its open position, and

Fig. 4 is a vertical sectional view taken on the line 4-4 of Fig. 3.

Referring more particularly to the drawings, the device comprises two blocks 5 and 6, and each of these blocks 5 and 6 is provided with an angularly disposed face 7 and a straight face 8.

Secured to the block 6 on its angularly disposed face 7, by means of a pin 9, is a stationary guide 9, one end of which is notched as at 10, to receive the stationary guide 9 to maintain the blocks in proper relation to each other. The block 6 is provided on one end with a cut-out portion 11, and extending transversely of the cut-out portion 11 and spaced from the lower wall 12 thereof, is a pin 13, This pin also serves Specification of Letters Patent;

Application filed April 27, 1920, s mu No. 377,056.

to retain the blocks 5 and G'together in such a manner as to provide a single unit quoin.

The block 5 is provided with a bar 14, which is spaced from its angularly disposed face 7 by means of a spacing block or the like 15, and said bar 14 is secured to the block 5 by means of threaded bolts or pins 14. This spacing block 15 is so positioned with respect to the block 5 as to maintain the bar 14 in parallelism with the angular wall or face 7 of said block, it being understood that the opposite end 16 of said block is notched as at 17, to receive the bar 14. This bar 14 is provided throughout the major portion of its length with a plurality of spaced notches adapted for engagement with the pin 13 to prevent relative movement of the blocks 5 and 6 under ordinary operating conditions.

To provide for the movement of the blocks 5 and 6 relative to each other in the operation of the quoin, these blocks are provided with notches 20 in their angular faces, and said notches 20 are adapted to be engaged by means of a key or wrench as in the ordinary manner. It has been found, however, that in these devices it is advantageous to provide a reinforcement for blocks, and therefore the notches have been filled in throughout a portion of their length with lead or other suitable reinforcing composition 21. This reinforcing material may also be formed as an integral part of the blocks, if desired.

From the foregoing description, it will be apparent that when the quoins are positioned between the chase and the type and are moved with respect to each other to lock the type in the chase or frame, the pin 13 will engage one of the notches 18, and the relative position of this pin to the notches 18 will prevent the slipping of the blocks 5 and 6 relatively to each other under ordinary conditions. Such a construction greatly enhances the qualities of devices of this character over the common type in which the frictional contact of the angular surfaces one with the other and the frictional contact of the straight surfaces with the walls of the chase or frame are relied upon to retain the blocks of the quoin against relative movement one to the other.

Having thus described the invention, what is claimed is:

1. A prlnters quoln comprising two members having angular faces in slidmg contact with each other, a pair of spaced lugs ried by one of said members,'a spaced bar formed on one of the members, a spaced carried by the other of said members and bar carried by the other of said members PFOVidGdJWith a'plurality .ofnotches, and a and adapted to travel between the spaced transversely-extending pin mounted in the 5 lugs to form guiding means, and a translugs and adapted for engagement with the 15 versely-extending pin overlying the spaced notches in said spaced bar, said pin serving bar wherebyrelativeomovement ofuthem'em- 'to prevent relative movement of the Inem hers is prevented. bers in all directions.

2. A printers quoin comprising two mem- V i 10. hers having angular faces, spaced lugs car- GEORGE DUNCANSON, JR. 7
