PRINTERVS CHASE.
SPECIFICATION forming part of Letters Patent No. 570,928, dated November 10, 1896.
Application filed December 31, 1895. fierial No. 574,274. (No model.)
, pivoted in slots formed in one side and end of the chase and operated by means of a lever inserted in slots in the eccentrics, thereby producing pressure on end and side sticks.
In the accompanying drawings, Figure 1 is a plan view of a chase made in pursuance of our invention. Fig. 2 is a View of the side of the chase with eccentrics locked. Fig. 3 is a view of the eccentric, full size.
A A is the frame of the chase, made in the customary manner. About midway between the center of one side and end, respectively,
and the corners of the frame rectangular slots D D are cut from the outer to the inner face of the frame. Within the slots are pivoted, by means of transverse pivot screws or rivets, eccentrics E E, which are operated by a lever F, inserted in the slot Gin the eccentrics, revolving the eccentrics inwardly, producing a powerful pressure on the side and end sticks B and 0, thereby locking the form in the chase. The center of the pivot on which the eccentrics E E revolve is about three-sixteenths of an inch from the center.
The dotted line H 11 represents are described by the eccentric in revolving, the increase being very gradual after reaching a point forty-five degrees from the greatest point of pressure.
A segment of the eccentric opposite the part of the greatest eccentricity is cut away,whereby it is flush with the outside of the frame when the chase is locked and with the inside when unlocked. In newspaper-printing we have the chase of the proper size as to require no extra blocking.
When the form is properly justified and the end and foot sticks in place, each eccentric is partially revolved in succession, bringing the form well together. Then each eccentric is revolved as far as the slot will allow, giving sufficient pressure to lock securely, but not enough to spring the chase.
In small job-chases we revolve the eccentric only as far as it is necessary to give sufficient pressure to insure safe locking, as the eccentric willhold if not turned to the highest point.
\Ve claim as our invention The combination in a chase for newspaper and job printing having slots in the frame, eccentrics pivoted in the slots with the segment of the eccentrics which is opposite the part of the greatest eccentricity, being cut 65 away whereby, when the chase is locked no part of the eccentrics projects outside the frame and when unlocked no part projects inside same, and the eccentrics each being provided with a slot in which to insert an operating-lever, substantially as described.
