M. J. DI GACOMO PAPER HANGING MACHINE Filed March 14, 1929 5 Sheets-Sheet 2 @Wip Apn'll, 1930. n M J. D. GIACOMQ 1,752,898'A PAPER HANGING MACHINE l w Filed March 14, 1929 3 Sheets-Sheet 3 14 thus enabling the brush to swing to follow Warped surfaces.

To cut paper at the end of'a strip as for instance at the edge of a baseboard after a strip of paper beginning at the ceiling corner of a side Wall has been applied by the device, there is shown aknife in the form of a revoluble` disk 52 mounted upon the slotted end of a shaft 58 and telescopically carried by a cylindrical socket 54 mounted upon a carriage55. To enable the cutting disk to follow irregularities of the Wall, the same is slidable in the socket 54 and retained therein as by means `of a pin 56 passing `through the shaft 53 and projecting into

slots

57, 58 in the Wall of the cylinder. y .To force the shaft outwardly in the cylinder, there is shown a spiral `spring 59 acting in compression between the end of the shaft` and the bottom of socket 54. i

To enable the knifev to be'iused either dur ing travel, as already indicated, or to cut a strip ofpaper longitudinally, the socket 54 is mounted upon a disk 60 which is revoluble about the mounting screw 61.

To hold the disk 60 in its desired position, there are shown retainingmembers, as Aballs 62,63 pressed upwardly to project through perforations in the `lovver disk 64 of the knife 3Q) carriage as by means of spiral springs 65,

66carried in sockets67, 68,Whioh sockets are secured to the disk 64.`

` `In the use of the device when papering-a surface Without openings the knife Will be Ways upon thecurved

portion

91 or 92 soasto be at one side or the other `of the strip to beplaced. i Paste is applied `to the end of the strip of paper which i automatically cut the paper during its apf-` open'm is then placed againstthe Wall at one end of the space to which it is tobeapplied and the control valves are opened to allow paste to be expelled throughV the spray head 27 when the brush is moved to apply the paper tol thel Wall. At the end of Vthe strip as When the baseboard is reached, the control valve is closed and the crank 90 is revolved having the cutter 52 in the position shown in Figs. 5, 6, and 7 thus causing the cutter to :move across the strip of paper to cut the same; after Whichthe process may be repeated with the neXtstrip. Y v

1f paper is to be applied adjacent .a wall opening when only a .portion of awidthis needed, the fullwidth of the paper may be applied abovethe opening in the manner alreadydescribed for a full Width str1p,`the

`knife maybecaused to travel to cut oi the above the opening and may be carried osition'opposite thelvertical side of the and by pulling on the appropriate Wire6 or 70 the knife may be turned to the position shown in Fig. 1, whereupon as the device is `moved downwardly the knife will p iper to a plication.

To revolve the disk 60 upon the disk 64, there are shown a pair of flexible members, as

Wires

69, 70 extending from a position alongside the handle 10 through

guide tubes

71, 72 and through ears 7 3, 74 carried by a ange 75 projecting from the socket 54, the ends of the Wires being secured to the ange as at 76, see Fig. 6. It will be seen that by pulling upon the

appropriate member

69 or 70, the socket 54 may be revolved through an are of 90 to place the knife into the desired position.`

'To mount the knife movably the disk 64 is shown as provided with

lugs

77, 78, which engage about ways 79, and to cause the .knife to lincline toward the brush in the position shown in Figs.1 and 6 a spacing lug 81 is shown opposingthe 1ug77 and contactingvvith the opposite side of way 79.` i

Tojcause travel of the` thus described carriage upon the

ways

79, 80, there is shown a belt 82 which is desirably of the character indicated in Fig. 2, said belt is shown as at tachedto the

carriage bygrip members

83, 84,` shown in detail in jFig. 7, and the belt Whichis endless about

idle pulleys

85, 86, 87, 88 and: about a drive sheave 89 which may be` revolved as by means ofa crank 90 to drive the `belt and thus cause travel of the knife. y y j When using the device upon a side wall the upper` portion' ofwhich is out of reach of theoperatonthe valve 38 may beclosed and the valve 35'vmay beopened before beginning the application` of the paper and the control of.r the paste `Willthen be possibleby` use of `valve 38 `which is Withinthe reach `of the operator manipulating the device by using the extension handle 12. When the bottom of the stripfis approached by the valves 3 5 and` 38 `being opened, the flow of paste may "becut oif by using valve 35 after which valve 38 maybe closed preparatory to opening valve 35 for repetition of the process."

` ofthe appended claims without departing from the spirit thereof.

1. A` paper hanging machine comprising, in combination, a supporting `member, a paper vsupply'roll carrier mounted on said member, means pivotally mounted fonA said member on an axis normal to the `plane of the paper to press paper against a surface, said means yieldable about said pivot to follow irregularities of the surface and means to apply adhesive to the paper as it leaves the supply roll. f-

2. A paper hanging machine comprising, in combination, a supporting member, a paper supply roll carrier mounted on said member, means pivotally mounted on said member on an axis normal to the plane of the .paper to press paper against a surface, said means yieldable about said pivot to fol low irregularities of the surface, resilient means to hold said means normally rin a central position and means to apply adhesive to the paper as it leaves the supply roll.

3.
