T GFFWEQ NELLIE MAE SHAFFER, OF DES-MOINES, IOWA WALL PAPER REMOVER Application filed May 25, 1929. Serial No. 365,989. r
The principal object of this invention is .to provide a device for the removing of old wall paper from the walls and ceilings of rooms that is economical in manufacture, and durable in use.
A further object of my invention is to provide a steam wall paper remover that requires the utilization of a minimum amount of steam.
A still'further object of this invention is to provide a steam wall paper remover that is capable of removing wall paper from ceilings without tiring the operator.
A still further object of this invention is to provide a steam wall paper remover that is self-supporting when thewall paper is being removed from a ceiling, and one that may easily be adjusted to ceilings of various heights.
These and other objects will be apparent to those skilled in the art.
My invention consists in the construction, arrangement, and combination of the various parts of the device, whereby, the objects contemplated are attained as hereinafter more fully set forth, and illustrated in the accompanying drawing, in which:
Fig. 1 is a side view of my invention ready for use.
Fig. 2 is a side view of a portion of the invention when used to remove wall paper from the ceiling of a room.
Fig. 3 is a top plan View of the steam tray.
Fig. 4 is an end view of the steam tray in M the tray supporting members.
F1g. 5 isa cross sectional view of a portion of the steam tray.
One of the most difiicult tasks in the repa-v tray that does not require manual effort to hold it adjacent the ceiling.
I have used the numeral to designate a steam producing tank having the water filling opening 11. This tank is designed to be partly filledwith water and subjected to heat. In Fig. 1, I illustrate this tank resting .on a gasoline stove 12', shown in conventional form, but any other heat producing means maybe used. On top of the tank 10 and igmmunicating with the same is a steam cone Secured in the small end of the cone and extending'some distance into the same is a metal pipe 14. By the pipe 14, extending into the cone, condensed steam forming on the inner side'of the cone will not be carried with the live steam through the pipe 14, but
Will drip back into the tank 10. This means that the steam passing out of thepipe 14 will 7 be comparatively dry.
I have used the numeral 15 to designate the steam tray having the rubber strip 16 embracing the marginal edge of the tray as shown in Fig. 5, and communicating with the inside of the tray 15 is a short pipe 17 The numeral 18 designates a flexible hose designed to haveone end engaging the pipe 14 and its other end engagingthe pipe 17 By this arrangement steam f ormedin'the tank 10 will pass through the hose 18 and into the tray 15. By manually holding the tray by the handle 19 against a surface having wall paper to be removed, thesteam in the tray will engage the wall paper and steam the same loose from'the surface. The rubber embracing strip 16 .aids in sealing the marginal edge of the tray against the surface to which the tray is applied, thereby preventing loss of steam "and causing the steam to more successfully attack the wall paper to be removed.
This described part ofthe invention operates very successfully. on vertical walls, but when used toremove paper from ceil ings and the-like, the manual holding of the tray against the ceiling becomes very tires'ome. To overcome this I have provided a tray supporting member which I will now describe. The numerals 20 and 21 designate two tray embracing members. Having'its two ends securedby suitable .means to the two'traymembers, respectively, is the spring yoke member 22. By this construction the two members 20 and 21 will yieldingly'em brace the two endv portions of the tray 15 as shown in Fig. 2, and hold thesame. To
Resting in the bottom of this bore-is a coil spring 26, designed to have one end engage the bottom of the bore 25 and its other end engage the stem end 27 of the spring yoke when the stem end is slidably mounted in the bore as shown in Fig. 2. The numeral 28 designates a second leg designed to have its lower end engaging asurface 29 such as a floor or the like. The numeral30designates a longitudinal slot in the lower. end,
portion or" theleg 24. Extending through the upper portion of the leg 28 and through the slot 80 is a bolt 31 having a winged nut 32. By this arrangement the legs 2 and 28 are not only secured together but are easily adjustable (by the bolt 31 passing through the slot 80), as to the distance between their two extreme ends, thereby compensating for ceilings of various heights. The legs should be so adjusted and secured that when the leg 28 is engaging the floor 29 the spring 26 will yieldingly holdthe tray15 against the ceiling 83 as shown in Fig. 2, thereby supporting the tray. To move the tray 15 to various positions over the ceiling the leg 28 may be lifted against the spring 26 until it is clear of the floor and the tray then slid to the desired position.
To remove the supporting portion of the invention from the steam tray it is merely necessary .to lift the tray outof the tray embracing members.
Some changes may be made in the construction and arrangement of my improved wall paper remover without departing from the real spirit and purposev of my invention, and it is my intention to cover by my claims any modified forms of structure or use of mechanica-lequivalents which maybe reasonably included within their scope.
I claim: v p
1 In a device of the classdescribed, a tray member, a pipe having one end communicating with the inside of said tray member, a. handle member secured to the bottom of saidtray member, a spring yoke. member, an elongated handle member secured to'said spring yoke, and an embracing member secured to each end of said spring yoke to frictionally engage and yieldinglyholdsaid tray mem her by engaging two sides and the bottom of said tray member.
2. In'adevice of the classdescribed; a tray member having sidewalls extending up wardly and outwardly, a resilient member secured; onthe marginal edge 0t saidtray member; apipe having one endcommunicating with the inside of said tray member, two
embracing members engaging the two end portions and bottom of said tray member respectively, a spring yoke member secured to said embracing members for yieldingly holding the same in engagement with said traymember, and an elongated handle member secured to said spring yoke member.
