WALL-PAPER-PASTING MACHINE.

Specification of Letters Patent.

Patented Aug. 17, 1909.

Application filed June 4, 1908. Serial No. 436,677.

To all whom it may concern:

Be it known that I, ALEXANDER 0. Ross, a citizen of the United States, residing at Hubble, in the county of Lincoln, State of Kentucky, have invented certain new and useful Improvements in Nall-Paper-Pasting Machines; and I do hereby declare the following to be a full, clear, and exact descript1on of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention has reference to a machine for applying a coating of paste or size to a strip of wall paper during its passage through the machine, it being the object of the invention to provide an exceedingly simple, inexpensive and effective machine of that class.

More especially, however, the invention aims to provide a machine, the several parts of which are, to a certain extent, separable, to permit the stale paste to be removed from the trough/and the entire machine cleaned.

With the above and other objects in view, the invention consists in the particular construction, combination, and arrangement of parts, all as hereinafter fully described, specifically claimed, and illustrated in the accompanying drawings, in which like parts are designated by corresponding reference numerals throughout the several views.

Of the said drawings, Figure 1 is a front elevation of the machine. Fig. 2 is a top plan view thereof. Fig. 3 is a vertical section taken longitudinally through Fig. 2. Fig. 4 is a side elevation showing the hinged upper section of the machine in raised position. Fig. 5 is a detail perspective view of the base frame of the machine. Fig. 6 is a detail perspective view of the upper or hinged frame. Fig. 7 is a perspective view of the paste pan.

Referring more particularly to the drawings, 7 designates the body of the machine, 8 the bottomand 9 the top thereof. The body 7 is in the form of an open frame of approximately rectangular shape, the end members 1.0 being provided upon their lower edges with longitudinal latches or cleats 11, with which the front and rear edges of the bottom 8 are engaged, said cleats extending beneath said section, to hold it in place, as shown in Fig.3. Thetop section of the machine, which is likewise in the form of an open frame, is hinged to the rear end member of the body and its sides 12 are connected adjacent their forward ends by a cross piece 13 upon Which a handle 14 is secured, said sides being further provided with sockets formed in their lower faces in which upivardly-projecting pins 16 set into the sides of the body 7 are adapted to fit, to prevent displacement of the frame top when the latter is in position upon the body. The bottom section 8 which is formed of galvanized iron, is provided with a central transversely disposed trough 18 which extends from side to side thereof, the front and rear ends of said section sloping slightly toward the trough, as shown. Into the trough, which is adapted to be filled with paste or size, extends the coating roll 19 which is mounted upon a shaft 20 fitted at opposite ends in bearings formed in the side members 17 of the frame body. The paste trough is arcuate in cross-section.

Located directly above the coating roll is a presser roll 21, provided with a covering of felt or other yielding material. This roll is mounted upon a shaft which extends through vertically-disposed slots 22 formed in a pair of uprights 23 mounted upon the side members 12 of the top section 9, which members are further rovided at their rear ends with blocks 24 in .whioh bayonet slots 25 are formed, for the reception of the ends of the spindle 26 upon which the roll of paper 27 is wound. The spindle ends carry small rollers 28, which, when the spindle is in place, lit in the lower ends of the inner arms of the bayonet slots, thus permitting an easy rotation of the spindle. The top section also car ries a pair of

guide rolls

29 and 30 which likewise extend from side to side of the section and are mounted upon shafts whose opposite ends are received in bearings formed in the side members of said section, the roll 29 being disposed intermediate the paper roll 27 and the coating roll 19, while the roll 30 is located at the front end of the frame. These rolls, as well as the roll 21, may be supported,

if desired, by trunnions located upon their opposite sides, the rolls being preferably formed, like the bottom section, of galvanized iron. The supply of paste taken up by the coating roll is regulated by means of a transversely-disposed brush31, which is located adjacent the

guide roll

29, and 18 held yieldingly against the coating roll by means of expansible coil-springs 32 which embrace the threaded bolts 33 uponwhich the brush is supported, said bolts projecting through threaded openings in the rear end piece of the body 7, and carrying thumb screws 34 by means of which the brush may be withdrawn from the coating roll. At the forward end of the machine is located a second brush 35 which is held yieldingly against the forward guide roll 30 by springs 36 similar tothose above described, movement of said brush away from said roll being eflected by means of threaded bolts 37 which carry said springs and are similar to the bolts 33.

' When the machine is not in use the presser rollZl is held out of contact with the coating roll 19, in order to prevent the application of paste thereto, the s ots 22 being provided for the purpose with angular extensions 38 at their upper ends.

The operation of the machine'may be described as follows: The roll of paper which has been previously wound upon its spindle, is inserted in place upon the blocks 24rcarried by the raised to section. The free end of the paper is then rawn across the coating roll and the edge of the forward brush.35, whereupon the top is swun into its lowered position upon the body 7, t us bringing the

rolls

21, 29 and 30 against the paper. When, therefore, the aper is drawn through the machine, it wifl be apparent that its under face will receive a coat of aste from the roll 19 against which it is yiel ingly held by the felt-covered presser roll 21, the movement of the paper causing the rotation of the several rollers. The paste applied to the paper is smoothed by the action of the brushes.

Where the pa er has been previously trimmed, it may be applied directly to the wall. If trimming is necessary, it may be turned back against the forward uide roll 30 and led thereon to, a trimming table, or other support, not shown. If desired, thetop section may be latched or otherwise connected to the body 7 during the passage of the paper through the machine.

At the completion of the asting operation, the top is swung into raised positlon, to permit the coating roll and main section or body of the machine to becleaned, and the bottom ma be removed to permit the removal of the sta e paste.

,What' is claimed is .1. In a machineof the class described,the

combination, with an open rectangular main frame section, of an open top section hinged at one end thereto, cleats secured to the under face of the main section, a metallic bottom section removably engaged with said cleats and including an integral depending paste trough, a coating roll carried by the main frame section and extending into said trough, and a presser roll carried by the top section and located directly above the coating roll, said presser roll belng provided with a facing of yielding material.

2. In a machine of the class described, the combination, with an open rectangular main frame section, of an open top section hinged at one end thereto, cleats secured to the un-F der face of the main section, a metallic bottom section removably engaged with said cleats and including an integral depending paste trough, a coating roll carried by the main frame section and extending into said trough, a presser roll carried by the top section and located directly above the coating roll, said presser roll being provided with a facing of yielding material, and spring pressed means dis osed upon opposite sides of the coating rol tity of paste applied thereby.

3. In a machine of the class described, the

combination,'with the main and top sections hingedly connected together, of a bottom section completely removable from the main v section and having a paste trough formed therein, a coating roll carried by the'main section and extending into the trough, a pair of vertically-slotted uprights mounted upon the top frame, and a presser roll disposed directly above thecoatlng roll and provided at opposite ends with supporting means fitting in the slots in said uprights, said slots being provided at their upper ends with angular extensions adapted to receive the roll-supportingmeans, to maintain the resser roll out of contact with the coating ro when the machine is not in use.

In testimony whereof, I affix my signature,

in presence of two witnesses.
