LUMBER-PLATFORM.

Specification of Letters Patent.

Patented Dec. 11, 1906.

Application filed February 26, 1906. Serial No. 303,078.

To all whom it may concern:

Be it known that 1, WILLIAM A. FELLnRs, a citizen of the United States, residing at Chester, in the county of Thayer and State of Nebraska, have invented certain new and useful Improvements in Lumber-Platforms, of which the following is a specification.

As is well known, lumber is arranged in a lumber-yard in piles, with alleys between. These piles of lumber are made considerably higher than a mans head, so as to utilize the ground to the best possible advantage, and when the piles of lumber become too high for a man standing on the ground to pile additional boards thereon it has heretofore been necessary for him to use wooden horses or trestles and step-ladders. The difficulty with accessories of this nature is that the lumber as it comes from the car is unloaded in the alley next to the pile that it is intended This is of course for convenience,but leaves a very unsatisfactory place for the use of a step-ladder or horse, as there is no solid place to set the same.

It is the primary object of my invention to overcome this difficulty by the provision of portable platforms that may be arranged with or connected to the piles of lumber at different elevations as the piles increase in height, so that there will always be provided a convenient place for a man to stand upon while placing additional boards upon the ile.

A further object of the invention is to provide an improved platform of this nature comprising a pair of portable supportingframes arranged to be detachably connected to the lumber-pile in a simple and easy manner and designed to project out from the pile and arranged to have boards laid thereupon from one portable frame to the complementaryframe, so that a man may stand upon the boards in convenient position for working.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawings, in which- Figure 1 is a perspective view of my improved invention applied. Fig. 2 is a side elevation of one of the supporting-arms for the platform. Fig. 3 is a top plan view thereof. Fig. 4 is a transverse sectional view.

Corresponding and like parts are referred to in the followin description and indicated in all the views of the drawings by the same reference characters.

My invention comprehends a pair of portable frames 1, that are arranged in juxtaposition to each other in connection with a pile of lumber. As these frames are substantially alike except in a minor detail which will be set forth, it will be necessary to describe the structural elements of only one. Each frame comprises a main supporting-bar 2, preferably of steel or similarly strong metal or material, provided with a curved end portion 3. The curved end portion 3 is provided at its extremity with a preferably integral offset lug or hook 4 and with a similar offset hook 5, preferably riveted thereto and preferably located at about the point where the curved end 3 of the main supporting-bar merges into the main straight portion thereof. The main bar 2 supports two spacedapart depending bars 6, that are connected together at the lower ends by a cross-bar 7. The bars 2, 6 6, and 7 constitute the frame, and the curved portion 3 of the bar 2, with its lugs 4 and 5, constitutes the means for detachably connecting the frame to a pile of lumber.

One of the depending bars 6 has secured to it upper and lower straps or loops 8, in which a rod 9 is mounted to move longitudinally. The rod 9 is provided with a series of holes 10, designed to receive a pin 11, working in the bar 6, so as to hold the rod 9 at different elevations With respect to the frame. The upper end of the rod 9 is forked, as best shown in Fig. l, to receive one of the gudgeons or trunnions of a roller 12, or, if desired, a piece of lumber or scantling 14, as best shown in Fig. 2, may be received in the forked ends of a pair of the rods 9.

In the practical use of my invention a pair of these frames 1 is secured to a pile of lumher at the required height, so that the bar 2 and cross-bar 7 will project out over the end of the pile and over lumber piled in the alley. Each frame is secured to the pile by means of the lugs or hooks 4 and 5, which are slid between the pieces of lumber in engagement therewith, so that the upper hook 5 will pull downwardly and the lower hook 4 will exert an upward pressure, and the two will thereby securely hold the frame in place. The frames may be spaced apart any desired distance, with their cross-bars 7 arranged in substantially horizontal alinement, and pieces of ICC lumber 13 may be extended over one crossbar 7 to the corresponding bar of the other frame, so that a man may stand thereon and continue to receive lumber over roller to be placed on the pile. The roller 12 is to be utilized to roll boards of lumber over it as it is being piled up, and as it is necessary to change the height of this roller to compensate for the ever-increasing height of the pile the adjustable connection of the rod 9 is provided.

It is to be understood that the lugs or hooks 4 and of one frame extend in an opposite direction from the lugs or hooks of the other frame, the two sets of hooks preferably facing each other, and it is in this respect only that the frames of a pair differ from each other.

From the foregoing description, in connection with the accompanying drawings, it will be seen that I have provided simple devices constituted by the portable frames for constructing a platform at different required heights along the end of a pile of lumber, so that the workmen may stand thereon and continue to lay boards or the like on a pile,

' while at the same time the ground space is clear for the lumber that is received from the car and is intended to be placed on the pile.

Having thus described the invention, what is claimed as now is 1. A device of the character described comprising two portable frames each of which embodies a supporting-bar provided with laterally-extending lugs adapted to take into the side of a pile of lumber, the lugs of one frame extending in a direction opposite to the lugs of another frame of the same pair, and a platform proper supported by said frames.

2. In a device of the character described, a portable open frame embodying a supporting-bar, said bar being provided with a downwardly-extending end, and offset lugs projecting from said end and designed to slip in and between the pieces of lumber in a pile so as to support the frame in an outwardly-proj ected positionfrom a side and extending out in front of pile over lumber in alley.

3. In a device of the character described a portable frame, comprising a main supporting-bar having a downwardly-extending end and provided With offset lugs out of alinement with each other, depending bars suspended from the main bar and a platformsupporting cross-bar connecting the depending bars, and a rod connected to said frame for the purpose specified.

4. In a device of the character described, a portable frame designed to support one end of boards to constitute a platform and provided with offset lugs out of alinement with each other and adapted to slip in between the boards of a pile so as to support the frame in an outwardly-projected position from the side of the pile, and a longitudinally-adjustable board-supporting rod connected with said frame.

5. In a device of the character described, a portable frame designed to support one end of boards to constitute a platform and provided with offset lugs out of alinement with each other and adapted to slip in between the boards of a pile so as to support the frame in an outwardly-projected position from the side of the pile, said frame being rovided with guide-loops, and a rod mounted to slide longitudinally in said loops and provided with a series of apertures designed to receive a pin whereby to hold the rod in different adjusted positions.

6. A device of the character described, comprising a pair of portable frames designed to support one end of boards to constitute a platform and provided with offset lugs out of alinement with each other and adapted to slip in between the boards of a lumber-pile so as to support the frames in an outwardlyprojected position from the side of the pile, said frames being provided with guide-loops, rods mounted to slide longitudinally in said loops and provided with apertures designed to receive pins whereby to hold the rods in different adjusted positions, and a roller carried by said rods.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM A. FELLERS.
