ALEXANDER FRITZ, OF MANAY'UNK, PENNSYLVANA.

PAPER-HANGING :MACHINE Application filed September 14, 1923. Serial No. 662,690.

To all whom t may concern:

Be it known that I, ALEXANDER FRITZ, a citizen of United States, residing at Manayunk, Philadelphia, in the county of Philadelphia and State ot Pennsylvania, have invented certain new and useful improvements in Paper-Hanging Machines; and l do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. l

This invention relates to that class of inventions commonly known as paper-hanging machines, the same having more specific reterence to a machine of this class which includes means for holding and permitting un- Winding ot the roll of paper so as to permit it to pass over a paste discharge slot in a container to permit pasteto be automatically applied to the reverse side of the paper, together with'a brush tor applying paper to the wall and a knife for severing the paper when the end of a single stretch is reached. As is usual, all ont the details for accomplishing these ends are mounted on a single portable hand-operated supporting device in such a manner as to permit them to operate in the proper order for facilitating the hanging ot paper. j.

It is one ot' the principal aims ot the invention to generally improveupon devices of the above-named type by providing one of extreme simplicity and durability wherein the parts are arranged in such a manner as to insure effective operation and vto provide a highly practical device.

More specifically speaking, it is a further and a very important aim to provide a machine ot this kind which embodies novel means for coacting with that portion ot a strip of paper which passes over the slot in the container, v'this means being adjustable andmanually controlled so that the thickness oit' the paste applied to the reverse side ot the paper can be accurately governed according to the grade and strength ot paper used. v

Another t'eature ot the invention is in the method of mounting the paste container or tank so that the same can be rotated about a pivot and held in various adjusted positions tor facilitating the discharge oic the paste to insure that every bit ot the paste can iow from the container regardless et metal frame 2 is secured.

1tlhdangle at which the supporting deviceis A still further feature ot' the invention resides in the provision of a soft-hair roller brush which is insured of positive rotation to prevent dragging ofthe brush on the paper which would have a tendency to tear it. Y

Other objects and'advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and inwhich like numerals are employed yto designate like parts throughout the same:

Figure 1 is a side elevation of a paperhanging machine constructed in accordance withthis invention, a portion of one of the wall engaging rollers being'broken away to disclose one of the details.

Figure 2 is a top plan view of themachine.

Figure 3 is a central longitudinal section taken on the line 3 3 of Fig. 2.

Figure 4 is a transverse section taken on the line 4 4 of Fig. 3. v

Figure 5 is an enlarged detail section taken on the line 5 5. of Fig. 1.

Figure 6 is an enlarged detail section taken on the line 6 6 of Fig. 2.

Figure 7 is a detail sectional view of a special design of brush to be used in corners of the room.

Figurev 8 is a detail perspective view of a tool used in conjunction with the machine.

Referring to the drawings in detail, the numeral l designates a handle, to the forward end of which a substantially'U-shaped This frame forms a supporting device for the Vseveral details to be hereinafter described. V

Mounted at the vinner end of the frame and journaled in bearings in the side bars thereofisv a comparatively `small removable rod 3 upon which the wall paper P is wound, the convolutions thereof being held tightly together and prevented from loosely unwinding by means of a fiat spring 4 which rests against .the roll of paper. Adjacent the roll of paper and secured between-the upper portions of the side bars of the frame is a guide rod 4 over which the strip of pape-r .is trained. After passing over this guide, the paper passes around the cylindrical paste container 5 and across allongituiii) dinal paste discharge slot 6 in one side thereof. On opposite sides of this slot are small guide rods 7 which are disposed in spaced parallelism with the slot, the paper engaging these rods in its travel across the slot. It may be conveniently mentioned here that it has been found highly desirable to control the amount of paste applied to the reverse side of the strip of paper according to grade` and strength of the paper. To accomplish this result l have provided unique means Which in its preferred forni cornprises a bar 8 provided with a contact strip or facing of rubber 9 which engages and forces the adjacent portion of the paper into the aforesaid slot 6, insuring that the paste will be evenly distributed over the entire Width of the strip of paper as it passes across the slot. It is desirable that this presser-bar, as it may conveniently be termed. is to be yieldablymounted and in carrying out this end l simply provide a yoke l having apertures adjacent its ends through which guide pins ll extend. these pins being surrounded by coiled springs 'l2 which serve to maintain the presser-bar in yieldable engagement with the paper.

So that fthe thickness of the paste applied may he accurately governed,4 l provide means for varying the pressure of this bar on the paper and in its preferred embodiment` the means comprises a lever 13 which is pivota-lly connected between its enc s 'with ears 14 on tl e aforesaid yoke. The free end ot this lever passes through an aperture in a plate l Which is connected at its ends with the aforesaid guide pins il.. ElConso quently when the lever .is rocked upon its pivot in a direction toward the roll of paper. the presser-bar ivill be retracted and pres sure upon the paper will he relieved, Hence, a greater amount of paste will be ap plied to the paper. .lot only is il' desi 5r-.bic to regulate the paste in this manner. but it is desirable that the sarne anioinit of paste will be applied to the strip throughout its` length. Therefore have provided means for maintaining the lever in a set position anc this means preferably comp-lees 'wife or other flexible element 16 which is connected to one end of the lever and is passed ov a pulley l?. This Wire is provided on ii" end with a ring or other suitable devi f. Ywhich is ada: to be selectively ened with one of the pins 1.9 on the aforein handle. lt is evident that when 'the rinn; is engaged with the foremost pin. the pressure. of the presser-bar will be greater than when the ring` is engaged with one of the remaining tivo pins. lt is of course apparent that the laterally directed ends of the aforesaid yoke will be provided with slots Q() to permit movement of the giuides 2l on the ends of the presseubar.

fter the paper has passed over the slot teasers to permit paste to be applied thereto, it passes over another guide rod 22 then over spaced bars 23 which have their surfaces rounded. and finally over a rotary bristle brush Qfl to permit its being pressed aga-inst the Wall and attached thereto. At this point, attention is directed to the fact that the brush i24- is provided with comparatively soft bristles and the trunnions thereof er; tend beyond the bearings in the side bars of the frame in which they are journaled, these extending ends carrying soft rubber nall engaging Wheels 25 which serve to insure positive rotation of the brush and prevent slipping of the Wheels. lit is to be noted that )the diameter of the latter is greater than that of the Wheel, but when the device is in use. the soft bristles flex sufficiently to permit the Working bristles to become disposed in a plane with the periphery of the wheels when pressure is exerted on the brush. lVithout the wheels the brush would probably drag` orer the paper in great many pla-ces and if the paper were overlyv wet. i-t would probably tear. However. by having a soft-bristle brush and insuring positive rotation thereof by providing -Wheels for engaging the Wall. possible tearing of the paper is eliminated.

Another detail of the invention yet to be described is the cutting knife which serves to sever the paper when the end of a stretch is reached. The knife is here indicated by the reference character 26 and it Will "be seen from the drawings that it is horizontally disposed and cooperates With the aforesaid bars 23 in cutting the strip of paper. lt is desired that the action of this knife be more or less automatic in on eration and for this reason l have provided spring means for actuating the same. Directing attention now to FQ 5, it will be seen that one end of the knife blade is rigidly secured 'to a vertical spring-rotated spindle 27. the normal tendency of which is to swing the knife to operative position. For the purpose of preventing movement the knife during the papering operation. l provide a cord-controlled spring-pressed atch 28 (seen clearly in Fig. G) which enres with a donntnrned edge portion QS) (in the knife. The cord Q53 for controlling this latch is led over suitable guides on the trarne and terminates in a convenient point adjacent the handle to permit it heinn` pulled for permitting operation of the knife.

ltitilculty is sometimes experienced in fully euaptying the container of paste and for this reason l have mounted the same on a pivot shaft 30 journaled in bearings iu the side bars of the aforesaid frame. This arrangement peri'nits tilting of the tank to the proper angle With respect to the handle to insure that all paste Will be discharged.

llfi

It is desirable to hold the tank in various adjusted positions and for this purpose I increase the thickness of one of the end Walls of the tank as shown at 31 (Fig. 4) and then provide this thickened portion with sockets into which the inner end of a screw 32 eX- tends. The result is that thev position of the slot 6 in the tank can be disposed relative to the angle of the handle to insure emptying and the tank can be held in this position by placing the inner end of screw 32 in the proper socket.

Referring again to the cutting knife,l it will be seen that a diagonal rod 33 secured across the upper side of the supporting frame serves as a mounting for the aforesaid spring-pressed latch 28. Also, if desired, the free ends of the knife may be upturned as shown at 34: to provide a finger piece for convenient resetting of the knife.

I intend to use a supplemental ytool 35 such as seen in Fig. 7 in conjunction with the machine. The spaced rubber covered jaws 36 of the tool serve to grip the paper for pulling it through the machine at the starting of a new stretch and the rubber covered cross-bar 37 on the opposite end of the tool serves as a means for holding the paper against the wall to insure against slipping. Inv using the tool, the cross-bar 37 is simply held against the lower end of the strip of paper at the beginning of the operation and in practice this crossbar will .be substantially7 the same width as the strip of paper with which it is engaged. The rubber sleeves 38 and 39 on the cross-bar and jaws respectively prevent tearing of the paper.

In operation, the paper unwinds from the roller 3, passes across the slot in the paste container, where paste is applied thereto, then passes over the guide bars 22 and 23 and around the brush 24 which is pressed against it to cause it to adhere to the wall "'5 surface. When the end of a stretch of pa` per is reached, the pull cord co-ntrolling the latch 28 is pulled and the knife 26 automatically moves between the bars 23 to sever the strip of paper. It is obvious that to change the degree of pressure of presserbar against the paper, the cord 16 is manipulated.

`When using the machine in the corners of the room the type of brush described, must be removed and a dierent type, such as shown in Fig. 7 substituted therefor. leferring to this figure, it will be seen that the brush is indicated generally by the reference character 40. The aforesaid wheels `are eliminated and the bristles 4:1 are so shaped as to permit the brush to press small strips of paper in corners of the room.

Although the machine has been described as being' of a specified size, I wish it to be understood that it may be of any size and the details may be varied within the scope of the subjoined claims. I contemplate for instance making the machine up as a toy in some instances.
