2 Claims. (01. 199-55) My invention relates to improvements in moldfastened stud 16 on which is mounted the mold cap filler bars for intertype line casting machines disc 11 for revolution.

Figs. 5-10 are drawn on alarger scale, and the The line of type shown in Figs. 5 and 6 is slugs illustrated in Figs- 5, 7 and 9 are shown as assumed to have been cast in the mold 34 when being broken away at each end thereof. the bar 25 formed a part thereof. As stated, the Similar characters refer to similar parts in the scale to which Figs. 5 and 6 are drawn is larger several views. than that of Figs. 1 and 2. This line of type con- With more particular reference to the desigsists of slug 27 on which is small type 29, and the 55. nated parts: On the frame 12 of the machine is overhang 28 on which is larger type 1128. The 1.

relative position of the bar 25 to the type bar when the latter was in the mold is indicated in dotted outline in Figs. 5 and 6.

In Figs. 9 and 10 are shown two views of a line of type assumed to have been cast in the mold 34 when the bar 25 was not used as a part thereof. This line of type consists of the slug 30 on which is small type 1231, and the slug overhang 31 on which is larger type (131. The height of overhang 31 is the greatest which can be cast in the mold 34 without extending the walls thereof by using the bar 25. It is easily seen that letters 1131 are smaller than are letters a28 although both are drawn to the same scale. This difference in height of the letters favorable to those on the overhang 28 is attributable to the use of the mold filler bar 25 as explained above.

In Figs. 7 and 8 are shown two views of a line of type which is larger than any that could be cast in mold 34 without using the bar 25, yet it is no larger than is the type a28 on overhang 28 which, as stated, could be cast in the said mold by using bar 25 as a part thereof.

It is now clear that the use of the mold-cap filler bar 25 as an added part to the mold 34 makes possible the extended use of this mold beyond what could be cast therein, and that without using a different mold cap therewith. It is also clear that the bar 25 may be used for increasing the size of the mold and yet a slug with small letters cast thereon as well as the overhang with larger letters thereon be cast in the said extended mold.

That is, the use of the disclosed mold-cap filler bar increases the range of the type which may be machine.

The disclosed method of employing the moldcap, filler bar has, in practice, been found tobe convenient. However, any other means of fastening the same in place of the same general character also is within the purview of this invention, and I desire to have it so understood.

Having thus disclosed my invention, what I claim as new therein and desire to secure by Letters Patent is,-

1. In mechanism of the kind described, a mold body, a mold cap adapted for being releasably fastened to the said mold body, the first elevator jaws, a matrix, having a type recess therein, retained in the said first elevator jaws operatively bearing on the said mold body disposing the said type recess adjacent the said mold cap and extended beyond the same, a mold-cap filler bar having its bottom and rear edge operatively disposed to rest on the said mold cap and on the said matrix adjacent the said extended portion of the matrix recess with its front face flush with the front face of the mold, lugs on the said filler bar, and fastening bolts and nuts bearing on the said lugs disposed to clamp the said mold cap filler bar and mold cap in operative position.

2. In mechanism of the kind described, a mold body, a mold cap adapted for being releasably fastened to the said mold body, the first elevator jaws, a matrix, having a type recess therein fastened to the said first elevator jaws operatively bearing on the said mold body disposing the said type recess adjacent the said mold cap and extended beyond the same, a bow-shape mold-cap filler bar operatively disposed with its convex bottom and rear edge resting on the said mold cap and a plain side thereof on the said matrix adjacent the said extended portion of the matrix recess with its front face flush with the front face of the mold, lugs on the said filler bar, and
