WALL-PAPEEHANGING DEVICE;

Specification of Letters Patent.

rammed D'ec.3,1912.

Application filed March 13, 1911. Serial No. 613,959.

To all whom it may concem Be it known that we, WILLIAM J. DUNN and HENRY B. TAYLOR. both of the cityv of Montreal, in the Province of Quebec and Dominion of Canada, have invented certain new and useful Improvements in \Vall- Paper-Hanging Devices, and do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilledin the art to which it appcrtains to make and use the same.

This invention relates to wall paper hanging machines and the object is to provide an improved means for discharging the trimmed and pasted paper from the device.

A further object is to provide improved paper pasting means.

To accon'xplish these objects, a regulating scraper is provided in the pasting device and also a brush adapted to distribute the paste evenly on the paper. At the front of the machine is an open framework supporting a carrier composed of a plurality of chains which engage the damp paper and prevent it curling. at the same time carrying it out of the machine.

Referring to the drawings --Figure 1 is a vertical ectional view of the device. Fig. 2 is a partial plan view of same.

In the drawings, 3 designates a frame work suppo-rting the various members of the pasting and trimming devices. The pasting device comprises a reservoir 4. containing a revolving drum over which the papcris fed from the roll (5 by means of teed rolls 7 and idler rolls 8. On the ends of the feed rolls 7 are knives which trim the edges of the paper smooth and parallel. After leaving the pasting device. the paper passes through discharging rolls 9, and over a table 10, with which a knife 11 coi'iperatcs to cut the paper transversely at any desired point Beyond the transverse cutting device. is the matching table. over which the paper passes in contactwith a tixcd sample thereof, in order that the precise cutting all point i may be determined. Formerly we made this matching table in the form ot a plate having the matching apertures therein. It was found thatv after a strip ot paper had been cut off, the end or the next freshly pasted strip, at'tcr passing over the transverse cutting table, had a tcndcncv to url. This curling ot the paper not only ruHlttl i As the paper leaves the the pattern side of the. curled portion but left some paste on the matching table where it would soil the nncurled portion of the paper. To overcome this great disadvantage, we substitute for the solid table a dis charging conveyer consisting of a number of endless chains 12, having comparatively large links. The chains pass over sheaves 13 mounted on parallel shafts 14, one of which is preferably driven from the discharge .rolls 9 by means of chain gearing 15. The drive is preferably soarranged that the chains 12 will have a. greater surface speed than the discharge rolls 9.. After a strip of paper has been severed and removed, continued operation of the device immediately projects the end of the new strip onto the chains 12. As the paper is pasted on the upper side. any tendency to curl will throw the end of the strip downwardly between the links of the chains, where it will be held by its own tendency to curl. Since the chains l2travelfaster than the rolls 9 and therefore faster than the paper, the chains will have theeftect of straightening out the curl in the strip and'thus prevent the paper. from rolling up. After the paper passes over the edge. 16 of the table, will overcome the tendency to curl. The matching of the pattern of the paper is accomplished as before the samples being held over the apertures 17 by meansof plates 18 and springs 19.

Between the discharging rolls 9 and pasting device. is an adjustable cutter 20 for splitting the paper strip into two strips. In

' order to readily gage. the adjustment of this cutter. a slidable scale 21 is provided, one end of whichmay be adjusted to the edge or the paper. The cutter 20 is then positioned as desired according to the graduations of the scale.

The improvement:- embodied in the pasting device comprise the use of a stiff heavy bar 22 as a scraper for the paste roller 5. This bar is vertically adjustable by means of screws 23 passing through brackets 24 horizontally adjustable on the framework 3. The bar 22 is preferably triangular in cross section as shown in order that a sharp scraping ct lgc may be presented to the-roll 5. End scrapers 25 for the roll are slidably mounted on the scraping bar 0, and are sccurcd at any point by set screwslG.

paste roll 5, there is a certain amount of suction which combined with the cohesion of the paste results in the paste being drawn into irregular ridges on the paper. ridges, and equalize the distribution of paste, a brush 27 is provided at the rear of the paste reservoir and held in place by brackets 28. This brush engages the pasted surface of the paper as itpasses over the rear idler 8, and distributes the paste evenly. Any surplus paste which is removed by the brush falls into the reservoir.

Having thus described our invention, What we claim is i I 1. In a paper hanging machine, a paper pasting and trimming mechanism, a discharging paper conveyer, and means for holding a sample of the paper adjacent the paper on said carrier. I

2. In a paper hanging machine, a paper feeding device, a paper pasting and trimming mechanism, and an endless discharging conveyer for the pasted paper traveling at a higher rate of speed than the paper.

3. In a paper hanging machine, a paper feeding device, a paper pasting a d trimming mechanism, an endless disc iarging conveyer for the pasted paper traveling at a higher rate of speed than the'paper, and means for holding samples of the paper adjacent the paper on the conveyer to determine the cutting ofi point.

4. In a paper hanging machine, a paper pasting, trimming and cutting off mechanism, a pattern matching device comprising a frame over Which the pasted paper travels, and means for holding samples of the paper in position for the pattern of the pasted paper to register therewith to determine the cutting off point and means on said frame To remove these paste for straightening out the curl of the paper caused by the wet paste.

In a paper hanging machine, a paper feeding device. a paper pasting, trimming and cutting ofi mechanism, a matching device comprising a frame over which the pasted paper travels, means for holding a sample of the paper on said frame in such position that the pattern of the pasted paper may be matched to determine the cutting off point, and an endless conveyer mounted on the frame and supporting the pasted pape", said conveyer traveling faster than the paper.

(3. In a paper hanging machine, a paper pasting, trimming and cutting off meclrrnism, a skeleton frame, endless conveyer chains mounted on said frame, plates adapted to hold samples of the paper at the end of the frame, and springs clamping said plates to the frame.

7. In a paper hanging machine, a paper feeding device, a paper pasting, trimming and cutting off mechanism, a skeleton frame at the front of the n'iaehine, shafts journaled therein, an endless chain conveyer mounted on said shafts and traveling at higher speed than the paper discharged from the pasting and trimming incchanisn'i, plates for held ing samples of the paper at the sides of the conveyer, and springs clamping said plates to the frame.

In Witness whereof we have hereunto set our hands in the presence of two witnesses.
