MACHINE FOR FORMING PICTURE-FRAME MOLDINGS.

SPECIFICATION forming part of Letters Patent No. 551,205, dated December 10, 1895.

Application filed April 19, 1895. Serial No. 546,356. (No model.)

To all whom it may concern:

Be it known that I, J AMES GIBSON, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Machines for Forming Picture-Frame Moldings, 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 machines which form moldings for pictureframes and analogous articles by means of an impression-roller having an embellished surface bearing upon a prolonged strip of plastic material applied to a wooden base which during the operation of the impressionroller is carried on a rotary bed-roller; and the invention consists in the improved organization and combination of parts of a picture-fram e-molding machine provided with a moistening and cleaning device for the impression-roller to prevent adhesion of the plastic material thereto and impairing its eiiiciency during the operation of the machine.

In the annexed drawings, Figure 1 is an end elevation of a picture-frame-molding machine with my cleaning and moistening device combined therewith, and Fig. 2 is a side view of the same.

Similar letters of reference indicate corresponding parts.

A and A represent portions of a moldingmachine having bearings M in which is supported the shaft h of the impression-roller a, and directly below said roller is the bedroller h.

In the operation of said machine, a wooden base j of the desired shape having a prolonged strip of plastic material 6 applied thereto is passed between said rollers and by reason of the configurations of the impression-roller and its pressure upon the plastic material, ornamentation is imparted to the same, thereby applying to the wooden base an ornamental facing which subsequently solidifies. Directly over the impression-roller a is my cleaning and moistening device which consists of a revoluble roller 19 formed of sponge or analogous material supported on ahanger chung on a bracket or support B, said hanger having formed in its upper portion a longitudinal slot 41 and is vertically adjustable toward and from the impression-roller a on the bracket B by means of the attaching-bolt f passing through said bracket and slot and provided with a nut f by which the hanger is clamped in its position. The lower portion of said hanger is formed with two downwardlyprojecting parallel arms 0 c on which is hung the shaft. d of the revoluble cleaning and moistening roller 19. Said roller may be formed of any suitable pliable material, preferably of sponge, and bears against the impression-roller for the purpose of moistening the same to prevent adhesion of the plastic material to the same and also clean said roller. Said roller may be kept moist by any wellknown means.

For exemplification I have shown a tank 9 supported on the bracket B, a sprinkler d directly over the roller, a pipe g leading from said tank to the sprinkler and a valve 1) in the pipe to control the flow of water.

By means of the aforesaid adjustment, impression-rollers of various sizes may be em ployed and the pressure of the cleaning and moistening roller upon the impression-roller may be regulated.

Having described my invention, what I claim is- In a machine for forming picture frame moldings, the combination of the impressionroller -a, a bed-roller h supported below said impression roller with a passage between said rollers for the reception of the Wooden base -j having a prolonged strip of plastic material -eapplied thereto, a hanger c hung on a support B above said impression-roller and provided with a longitudinal slot -n-, a bolt passing through said slot and support by which said hanger is vertically adjustable toward and from said impression roller, a nut clamping the hanger in its adjusted position, said hanger formed with two vertically parallel arms cc', the moistening and cleaning roller b secured between said arms and bearing on the impression roller In testimony whereof I have hereunto.

signed my name this 1st dayof April, 1895.
