PRINTERS QUOIN.
SPECIFICATION forming part of Letters Patent No. 484,907, dated October 25, 1892. Application filed December 26, 1891. Serial No. 416,175. (No model.)
To all whom it may concern.-
Be it known that I, ANGUS CAMERON, a subject of the Queen of Great Britain, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Printers Quoins, of which the following is a specification.
My invention relates to certain improvements in printers quoins, designed to simplify and strengthen the same as much as possible and at the same time bring them within the smallest possible compass, so that as little space may be taken up in the form as is consistent with strength and efficiency.
To such end my invention consists in certain improvements, which will be clearly described in the following detailed description, and the essential characteristics of which will be closely defined in the claims appended hereto.
These improvements are illustrated by means of six figures in the drawings presented herewith, in which- Figure l is a plan of a portion of a form, showing two of my improved coins in place. Fig. 2 is a vertical longitudinal section in line 2 2 of Fig. 1. Fig. 3 is a transverse section in line 3 3 of Fig. 2. Fig. 4 is a similar section showing the parts in a different position; and Figs. 5 and 6 are transverse sections in line 5 5 of Figs. 1 and 2, showing the quoin in the same two positions as Figs. 3'
and 4..
Applying letters to the various parts, the quoin consists of two blocks A B, one above the other, and having flanges or US a b, so arranged that when the blocks are placed together these flanges will present continuous and unbroken sides upon the two edges of the quoins. This is to give a perfect bearingsurface against the sticks or leads throughout the full height of the latter.
To enable the two blocks to be forced apartv a square hole 0 adapted to receive a square key, by means of which the eccentric may be turned.
By looking at Figs. 3 and at it will be seen that the turning of the eccentric into one position brings the blocks A B together, and turning into another position forces them apart.
It is possible that the friction upon the eccentric-pin may sometimes be sufficient to hold the quoin firmly and securely in any desired position; but to leave no possibility of displacement I provide a wedge-shaped block D, secured by means of a screw E to the block B, and I form upon the block A an incline b adapted to engage with the block by screwing the latter tightly against it. The quoin will be held positively against a return, but may be still farther extended by the use of a key, inasmuch as the wedge and the incline render movement easy in the direction which widens the quoin. A fiat block could of course be used in place of the wedge; but it will not be desirable, for the reason that the resistance to extension of the quoin would be as great as to the contraction thereof. It is obvious, of course, that the friction-block D can be used in any quoin of the same class as the one shown, and I do not desire to limit myself to any combination or combinations of my improvements other than those clearly pointed out below.
I claim as new and desire to secure by Let ters Patent 1. A printers quoin containing two blocks, one arranged above the other and provided with means for sliding them laterally one upon the other, one of said blocks having a flange or L adapted to extend over the edge of the other block and form a continuous bearing-surface upon the edge of the quoin, substantially as shown and described.
2. A printers quoin containing two blocks, one above the other, and an eccentric-pin passing through said blocks and adapted by rotation to slide the same one upon the other, substantially as shown and described.
3. A printers quoin containing two blocks,
one above the other, and provided with means for sliding them laterally one upon the other, and also for clamping them together, substantially as shown and described.
4. A printers qnoin containing two blocks, one above the other, provided with means for sliding them laterally one upon the other, and also with a wedging-elamp adapted to bind the two together and to offer a greater resistto ance to a contraction of the quoin than to an extension thereof, substantially as shown and described.
5. In a printers quoin, the combination of the two L-shaped blocks A B, the eccentricpin 0, the wedge-shaped block D, and the t5 screw E, substantially as shown and described.
ANGUS CAMERON.
