WALL MATERIAL nors'r Charles A. McPherson, Edgar, Mont. Application November 23, 1943, Serial No. 511,450

(on. sol-o) 3 Claims.

The present invention relates to new and useful improvements in wall material hoists, and has for its primary object to provide, .in a manner as hereinafter set forth, novel means for facilitating the application of wallboard, plywood, et,

caters, to the ceilings of buildings.

'Anothervery important object of the invention is to provide a hoist of the aforementioned character which, when it is so desired is adapted tov be expeditiously disassembled for storage or transportation.

Other objects of the invention are to provide a hoist of the character described which will be comparatively simple in construction, strong, durable, highly efllcient and reliable 'in use, compact, light in weight and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will'become apparent from a study of the following speclflcation, taken in connection with the accompanyv ing drawings, wherein like characters of reference designate corresponding parts throughout the v several views, and wherein: 1

Figure 1 is a perspective view of a; hoist constructed in accordance with the presentinvention.

Figure 2 is a view in vertical section through the device.

Flgure'3 is a top plan view..

Figure 4 is a fragmentary view in vertical sec-,

tion, showing the-means for frictionally clamping the'hoist in adjusted position.

Figure 5 isa view in horizontal sectionthrough the standard, taken substantially on the line 5-! -\of Figure 2.

Referrlngnow to the drawings in detail, it will be seen that the embodiment of the invention which has been illustrated comprises sheets which is designated generally'by reference numeral I..

The base I includes a four-way fitting '2 which is provided with an upstanding, centrallyloc'ated coupling v3. The branches of the fitting 2 have threaded thereinto one end portion of comparatively'long and short tubular metallic-legs I and 8, respectively; Smooth tubular braces O are welded onthe ends of the fitting) for preventing A tubular, telescopic sectional standard I! is mounted on the base I. The standard Ill includes a removable lower section I l which is threadedly mounted in the coupling 3. A reducing coupling l2 connects a comparatively long intermediate section l3 to the lower section II. The members ll, I2 and 13 have openings H therein for section 15. A vertical rod I1 is provided for adjusting the section IS. The. rod l1 terminates in a right angularly projecting upper end portion l8 which is engaged in an opening provided therefor in the section I5 above the section It. At its lower. end; the rod I'I terminates in a horizontallyprojecting handle IS. The lower portion of the rod I1 is flxed'in a metallic loop 20 which is-slidable on the section [3 of the standard l0.

Threadedly mounted in a boss 2| on the upper portion of the section 13 is a hand-operated set screw 22 for frictionally clamping the section I! in adjusted position. As illustrated to advantage in Figure 5 of the drawings, the loop 20 is substantiallyovate for spacing the rod H from the section ii for passing over the boss 2| when the set screw 22 is removed therefrom when assembling or disassembling the device.

' The section Ill is further provided with spaced openings 23 in any one of which a pin is insertible for engagement with the upper end of the section ll for positively preventing said section I! from falling should the set screw 22 loosen.

comparatively long and ,short tubular metallic arms 24- and 25. respectively, are threadediy mounted in the fitting l6. Tubular braces 25, similar to the elements v8, are provided on the ends of the fitting i6 forthe removable arms 24 and. Protectinglbars zi r wood, which contact the material, are secured on the arms 24 and-2i by clamps 28. The outer end portions of the arms 24 and 25 are provided with openings 2! for the reception ofthe turning tool.

It is, thought that the operation of the device will be readily apparent from a consideration of theforegoing. Briefly, the hoist is assembled and the material to be applied is placed on the members 21. .With the set screw '22 loosened, the section It is elevated in the section II through the medium of the rod I! for pressing the material upwardly in positionagainst-the'ceiling. The set. screw'22 is then tightened and, if desired, a pin may be inserted in the opening 22 which is closest to the upper end oi the section II. The material may now be nailed in the usual manner. The construction and arrangement is such that the material may be expeditiously and expertly applied by a single mechanic. It necessary, the section I! may be rotatably adjusted in the section 13 for positioning the material properly against the ceiling.

It is believed that the many advantages of a wall material hoist constructed in accordance with the present invention will be readily understood, and although a preferred embodiment of the device is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.

What is claimed is: p

l. A wall material hoist of the character described comprising a base, a telescopically adjustable standard mounted on the base, a plurality of'horizontal arms mounted on the upper portion of said standard. elongated bars removably mounted longitudinally on the arms, said bars being of appreciably greater width than the arms and having flat upper faces for receiving thereon the material, means for raising and lowering the standard, and means for securing said standard in adjusted position.

2. A wall material hoist of the character described comprising a base including a multi-way fitting, horizontal legs threadedly connected to said fitting, flat blocks detachabiy mounted beneath the outer end portions of the legs and constituting feet for the legs, a coupling rising from the fitting, a tubular, telescopically adjustable removable standard threadedly mounted in the coupling, means for vertically adjusting the standard, means for releasably securing said standard in adjusted position, and a plurality of arms mounted horizontally on the upper end portion of the standard and extending rearwardly thereof for receiving and supporting the material.

3. A wall material hoist including a base, a standard on the base, said standard comprising a tubular stationary section and a vertically ad- Justable section slidable vertically in said stationary section, a vertical rod for adjusting the slidable section, said rod having a lateral finger at its upper end extending through the slidable section and having a handle extending outwardly from its lower end, a'loop carried by the rod adjacent the handle and slidable on the stationary section, the rod being held spaced from said stationary section by the loop, a boss upon the stationary section near the upper end thereof, a set screw threaded through the boss for releasably securing the slidable section in adjusted position in the stationary section, and a plurality of arms mounted horizontally on the slidable section for receiving and supporting the material.
