Gay, N. Kenilworth, Mount Prospect, lli. Filed Aug. 16, 1961, Ser. No. 131,866 6 Claims. (Cl. 199-63) This invention relates to a mat holder composing stick and more particularly, to a stick which is especially de signed for use with paper mats.

A conventional slug-casting machine in common use today utilizes individual metallic molds or mats, usually made of brass, which are set in a frame or stick. The stick is then placed in the casting machine and molten metal is brought into contact with the mold. The end product is a slug incorporating the material from the brass mold or matrix which is used in the conventional fashion.

The metal molds or mats used in such an arrangement represent a substantial investment and it is an object of this invention to provide a composing stick which is particularly adapted for use with disposable paper mats rather than reusable metallic mats.

A further object is to provide a composing stick of the character described which is adapted to receive mats or varying lengths, a ready adjustment being provided to adapt the stick to a mat of selected length.

Still another object of the invention is to provide a stick of the general nature described which positively locks the paper mat in place in the precise position desired for accurate casting of the slug.

A further object of the invention is to provide a stick of the character described which is relatively simple in construction and yet suiciently positive in its action that it permits the use of paper mats rather than metallic mats, thus accomplishing a very substantial saving in operational costs and permitting the stocking of a wider variety of mats for job printing operations.

Further objects and advantages of this invention will become evident as the description proceeds and from an examination of the accompanying drawing which illustrates one embodiment ofthe invention and in which similar numerals refer to similar parts throughout the several views.

In the drawings:

FIGURE l is a perspective view of one form of the device showing a mat in piace in the composing stick ready for casting after insertion in the typesetting machine.

FIGURE 2 is a perspective view of the device shown in FIGURE l taken from the opposite side and pith the pivotal base member being shown in the partially open position.

FIGURE 3 is a longitudinal cross-sectional view of the device taken along the line 3-3 of FIGURE l, the mat being shown in position for casting.

FIGURE 4 is a cross-sectional view of abportion of the device shown in FIGURE 3, the section being taken along the line 4 4 of that figure.

As best shown in FIGURES l and 2, the stick is provided with a main body portion 10, substantially in the form of a frame, having a longitudinal central opening 12. A slide member 14, which is in slidable engagement with the main body portion 10, is adapted to vary the size of the opening 12 in the upper surface of the stick. A base member 16 is pivotally mounted to the main body portion 10 at one end 18 of the opening 12 in such a manner that when secured in position it will close the bottom of the opening 12, as shown in FGURE 3.

For the purposes of such pivotal mounting, a pin 20, which is in snug engagement with the base member 15, extends outwardly from the base member and into an elongate pivot hole 21 in the main body portion 10. The pivot hole 21 is sumciently large that the pin 2G is free to rotate therein. Furthermore, since the hole 21 is elongated, the pin 20 is also free to move slightly in a vertical direction to compensate for mats of varying thickness which may be placed in the stick. It will be understood that the pin 20 extends through the base member 16 and cooperates with another hole like the hole 21 on the other side of the main body portion 10.

The base member 16 is secured in position to the main body portion 1tl by means of a lock which comprises a locking arm 23 pivotally mounted upon an end 34 of the main body portion 1) by a bolt or rivet 22. In FIGURE 2 the locking arm 23 is shown in the position to which it is rotated to release the base member 16. The base member 16 is locked into position to close the bottom of the opening 12 by rotating locking arm 23 whereby the elongate end 24 of said arm extends into a groove 25 in the tree end 28 of the base member 16, as best shown in FIGURE 3. If desired the upper portion of the elongate end 24 of the locking arm 23 which engages the groove 25 may be beveled to assist cooperative engagement between the arm 23 and groove 25.

As best shown in FIGURES 2 and 3, the base member 16 may be provided with a plurality of suitable yslots 39 to increase the heat dissipation in this base member 16. The free end 28 of the base member 16 is provided with a step 32 which is adapted to cooperate with and rest upon the end 34 of the frame 10 when the base 16 is moved into position to close the bottom of the opening 12, as best shown in FlGURE 3. The lateral edges of the base member 16, which are moved into close association with the base of the slide member 14 when the base member is secured in the position shown in FIG- URE 3, have

steps

36 and 38 provided therein, as best shown in FIGURE 4. The lateral edges of the slide member 14 have

complementary shoulders

42 and 40 formed therein which are adapted to be received within the

steps

36 and 38, respectively, when the base member 16 is in the position shown in FIGURE 3.

As best shown in FIGURE 2, the slide member 14 and the frame or main ybody portion 10 form a frame for the paper mat 44, which is shown in place in FIG- URES 1, 3 and 4. The periphery of the frame thus formed is slightly dished out, as shown in FIGURE 2, so that relatively sharp edges are presented by these elements to the upper surface of the base member 16. The base member portion 1t) presents three of the sharp Aedges 46 and the slide member 14 presents the other sharp edge 4S. These sharp edges, as best shown in FIGURES 3 and 4, are adapted to grip the periphery of the mat 44 when the base member 16 is secured in the operatinU position, as shown in FIGURES 3 and 4. The leading edge of the slide member 14 is provided with a small shoulder Si! in slightly spaced relation to the sharp edge 48, as best shown in FIGURES 2 and 3. The shoulder 5t) is adapted to be brought into abutment with one side of the mat 44, the opposite side of the mat being in abutment with the end portion 34 of the frame 1G. This positioning of the mat 44 with respect to the slide 14 and the frame member 10 is normally carried out prior to the seating of the base member 16. When the base member is brought into the position shown in FIGURE 3, the edges of the mat 44 are compressed between the upper surface 52 of the base member 16 and the

sharp edges

46 and 48, as best shown in FIG- URES 3 and 4. The four edges of the mat 44 are thus sealed when the locking arm is rotated to secure base member 16 in place, as shown in FIGURE 3. Once base member 16 is locked in position slide member 14 is likewise prevented from moving.

Yof limitation.

A pin 54 may be provided in the frame 10, one end of which is adapted to be received in the slot 56 provided in the underside of the slide member 14, as shown in IGURE 3. The pin thus acts both as a guide for the slide 14 and a stop to prevent its complete removal from the frame member 10. A suitable opening 58 may be provided in the projecting extremity 6i) of the slide member 14 to permit the slide 14 to be more readily grasped by the lingers of the user and adjusted to its proper position.

As indicated, after the mat 44 has been put in proper position in the stick and the base member 16 locked into position, the stick is inserted in the conventional typecasting machine adapted to receive sticks of this general nature, such as the Ludlow Typecasting Machine. The shoulder piece 7% is provided on the frame member 1G aS a trip member for the safety mechanism on such a machine since the molten lead cannot ow into the `cavity unless this safety mechanism is released. The stick is locked in proper position in the machine so that a seal is formed around the mold cavity in the stick. The mat 44 is the base of the mold cavity in the stick and because it is sealed therein in the manner described hereinbefore, molten lead will not leak from the mold cavity. Upon cooling of the metal which has been poured into the mold, the stick is removed from association with the typecasting machine. The slug formed with the image of the mat thereon may then be removed from association with the stick and used in the conventional manner. fr?? l In the drawing and specification, there has been set forth a preferred embodiment of the invention, and although specific terms are employed, they are used in a generic and descriptive sense only and not for purposes Changes in form and in the proportion of parts, as well as the substitution of equivalents are contemplated, as circumstances may suggest or render expedient, without departing from the spirit or scope of thisinvention as further defined in the following claims.
