Application filed September 22, 1913. Serial No. 791,196.

To all whom it may concern: I

Be it known that we, CnoIL E. GLIBPINGER and JOHN A. SMITH, citizens of the United States of America, residing at Carmi, in

the county of lVhite and State of Illinois,

have invented certain new and usefulInrprovements in Adjustable Printers Chases,

of which the following is a specification, ref? erence being had therein to the accompanymg drawlngr This invention relates to a printers chase,

and the principalobject of the invention is to provide a chase with a plurality of bars which are so mounted that they may be moved so that a block of type may be held tightly imposition.

Another object of the invention is to provide an improved means for adjustably holding the bars in place.

Another object of the invention is to so construct the bars that they may be given an additional tightening movement after r they have been moved toward the block of type as far as the ratchet will permit.

This invention is illustrated inthe accompanying drawings, wherein:

Figure 1 is a plan view of the chase. Fig. 2 is a longitudinal sectional view taken along the line 2-2, of Fig. 1. Fig. 3 is a frag: mental-y sectional view of onecorner of the chase. Fig. 4 is asectional view taken along the line 4-4, in Fig. 3. Fig. 5 is a sectional view taken along the line 5-5, in Fig. 3. Fig. (3 is a perspective view of one of the pawl carrying heads which are carried by the sliding arms. of the pawl shown in Fig. 6. Fig. 8 is a )perspective view of oneof the cams which are used for giving thebars an additional tightening movement.- Fig. 9 is a perspective view of the key which is used for turning the cam shown in Fig. 8. Fig. 10 is a fragmentary sectional view taken along the line 1010 of Fig. 1.

This chase has a rectangular frame 10 which is made up of a plurality of strips as shown inFigalO. It should benoted that the strips forming the longitudinal bars of the frame are beveled as shown in Figs. 1

and 10 so that when the chase is put in the strips 12. and the intermediate strip .13 is cut to form teeth 14, thus forming atoothed Fig. Tis a perspective view rack between the strips 11. The protruding inner edge portions of the strips 11 are providedto constitute guidingjmeans for the barswhich are slidably connected with the 1 frame.

T he longitudinallyextending bars 15 are mounted in the frame and each is provided with a longitudinally-extending pocket 16 in which there ismounted an auxiliary strip 17. A head 18 is carried at each end of each of the strips 17 and extends to one side of the bar so that there is provided a pocket :in which a pawl 19 is pivotally mounted. 1 These pawls 19 engage the teeth 14, as shown in Fig. 3, and are yieldably held in engagefment with the teeth by the springs 20. This 1 construction permits the bars 15 to be moved toward each other and held in adjusted position so that the block of type which is placed between the bars will be tightly clamped.

The. strips 17 carry heads 18 which are jpositioned in alinement with the heads 21 iand are provided with cut-out portions regtistcring with cut-out portions formed inthe jheads 21 and forming pockets 2? in which ithe cams 23 are rotatably mounted. The isprings 2-11 normally hold the strips 17 in the grooves 16, but when the cams 23 are turned by the key 25, the strips 17 will be forced out of the grooves 16 against the tension of the springs 24 so that the block of type may be securely clamped in case the bars 15 do not tightly grip the block of type when moved toward the same as far as permitted by the pawls.

The transversely-extending bars comprise the major and auxiliary members 26 and 27, each of which is composed of the upper and lower strips 28 and 29 held in spaced relation, so that the longitudinally-extending bars can pass through the transverselyextending bars. Each of the major members carries a head 30 similar to the head 18, a pawl 31 being pivotally connected, with each of the heads 30 so that the pawls may engage the teeth 14 and hold the transversely-extendingbars in an adjusted position.

The auxiliary members 27 areprovided with heads 32 which are provided. with cutout portions registering with cut-out portions formed in the heads 30 and form pockets in which cams 33 are mounted.

The major and auxiliary members are held in, the position shown in Fig. 3 by the springs 34; so that the transversely-extending bars. The transversely and longitudi nally-extending bars arethen moved toward ing bars may be tightened in the same manner that the longitudinally-extending bars are. a V Y When using this chase, the block of type is put in the center of the chase between the transversely and longitudinally-extendthe center of the chase until. they are brought into engagement with the block 1 of type. bars in engagement-with theib lockot type so: that the type will be prevented -from dropping out, of the chase when thechase is lifted-and placed inthe press. It the bars do not clamp the type with sufficient tightp ness, the cams 33 can be rotated to bring the auxiliary strips into tight engagement I with the type. When the chase is removed from the press, the cams are returned to the normal position and the pawls are then pressed out of engagement with the teeth 14 and the clamping bars moved to release the block of type;

A scale shown in Fig. 1 is provided so that the bars may be properly adjusted in order tobring the block of type in the cen-. ter of the chase or inany other portion ofthechase whereit is desired tofhave the Copies of thispatent may be obtained for The pawls will hold the clamping.
