lMPRESSlON-ROLLER.

SPECIFICATION forming part of Letters Patent No. 468,071, dated February 2, 1892.

Application filed April 2, 1891. Serial No. 387,393- (No model.)

To aZZ whom it may c0nccrn:

Be it known that I, FRANK M. MOORE, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Impression-Rollers, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to the class of impression-rollers which are employed in the manufacture of moldings having their surfaces formed of plastic material, by means of which rollers the required embellishment is impressed in the surface of the molding while in a plastic state.

The object of the invention is to produce said impression-rollers in an inexpensive manner and at the same time impart to them the requisite stability and durability and also perfect accuracy and harmony in the repeated parts of the embellishment intagliated in the surface of the roller; and to that end it consists in the novel construction and combination of parts hereinafter described, and set forth in the claims.

In the annexed drawings, Figure l is a face View of the impression-roller in its operative position. Fig. 2 is an end view of the same. Fig. 3 is a longitudinal section on line no 0:, Fig. 2; and Fig. 4 is a detached perspective View of one of the sectors of the impressionroller.

Similar letters of reference indicate corre sponding parts.

R represents the in]pressionn'ollelywhich is usually mounted on a horizontal shaft s,which is journaled at opposite ends on suitable sup ports not necessary to be shown. A carrying-roller R is arranged under said impression-roller to support the molding m,which is passed longitudinally between said rollers,'as represented in dotted lines in Fig. 1 of the drawings, to receive the impression from the roller R. Said impression-roller has usually been formed in one piece of metal, and the ornamentation which is to be produced on the face of the molding was engraved or stamped in the surface of the roller, and in some cases such impression-rollers have been provided with design-plates detachably connected to the convex surface of the roller and were employed for marking designs upon cement pavements or walls. Such a construction is very expensive and the accuracy and harmony of the repeated parts of the ornamentations are verydifiiculttobeobtained. To obviatethese defects I form the body of the impressionroller R of three or more separate sectors to a a. In the majority of cases I divide said roller into four sectors, as shown, and firmly unite the same by means of suitable ties. Each of these sectors has intagliated directly on its exterior a section of the continuous ornamentation to be applied to the molding m. In constructing said roller I form a pattern of one of the sectors a, and then mold and cast therefrom of suitable metal the desired number of roller-sectors. Said pattern being formed of wood allows the ornamentation to be easily carved in the convex face of the sector-pattern, and inasmuch as allthe sectors are cast from one and the same pattern it is obvious that the consecutive portions of the ornamentation must be fac-similes and in perfect harmony in their sequential arrangement. To firmly unite the sectors a a a a, I preferably form each with a transverse groove 1) and with rabbets c c on opposite ends, which groove and rabbets intersect those of the adjacent sectors. The number of sectors required to form a roller I tie together by inserting solid metallic rings 25 ttin the groove and rabbets and then drilling longitudinally through the united sectors at such points as to form holes through the aforesaid rings and intervening portions of the sectors, into which holes I insert bolts or rivets (I (Z, as shown in Fig. 3 of the drawings.

I find that the simplest and most convenient manner of tightly fitting the rings t tt in the groove and rabbets consists in pouring melted white metal or Babbitt metal into the into the central eye 6 of the combined sectors snfficient to fill the groove and rabbets and then drilling out the metal contained in the central eye c.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The improved impression-roller composed b and rabbets c c, the metallic rings 25 t t in said groove and rabbets, and the bolts or rivets (Z (1 cl (1, passing through the said metallic rings and intervening portions of the sectors, substantially as described and shown.

In testimonyWhereofI have hereunto signed my name this 7th day of March, 1891.
