STAGING.

Specification of Letters I'atent.

Patented May 11, 1920.

Application filed September 18, 1918. Serial No. 254,588.

To all whom it may concern Be it known that I, FRED C. MILTON, a citizen of the United States, residing at Eastside, in the county of Coos and State of Oregon, have invented a new and useful Staging, of which the following is a specification.

The subject of this invention is a scaffolding or staging intended to be of a permanent character and useful, primarily, in ship yards, though suitable for many other purposes.

A main object of the invention is the provision of staging which may be easily moved to the side of the ship or other structure in course of construction.

Another obj ect of the invention is the pro vision of a staging which will allow the workmen to always operate in a standing position, and without undue stretching.

Another object of the invention is the pro vision of safety guards on the staging.

Another object of the invention is the provision of means for locking the various platforms of the staging.

The invention also contemplates generally improving the construction and enhancing the utility of the staging.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

A practical structure for carrying out the invention is shown in the accompanying drawings, wherein Figure 1 is a sectional View of a staging constructed in accordance with the invention, the same taken on the line 1-1 of Fig. 2;

Fig. 2 is a fragmentary view in front elevation of the same;

Fig. 3 is a plan view.

Referring to the drawings by numerals of reference In carrying out the invention, the staging is .preferably erected on the flooring or boards 10, and consists in uprights 11 at the forward or working side of the staging, and uprights 12 at the rear thereof. These uprights 11 and 12 are spaced as desired, and

forward and rear uprights 11 and 12, respec i'vely, are connected in pairs by the cross braces 13. Struts ll may be employed to support the staging, the lower ends of such struts being stepped in brackets 15, or the like, secured to the flooring 10, and the up per ends connected to the upper ends of the uprights 12 by straps 16 or the like, which straps overlie and straddle the meeting ends of the struts and uprights, and are secured in place by bolts or the like.

Secured to the forward uprights 11, and spaced longitudinally thereof, are the brackets 17 which are held'in place by the bolts 18 or otherwise, and which are rabbeted or recessed to receive and support Slidably mounted in the brackets 17, and

resting on the ends of the braces 19, are the supporting beams 20 to which the flooring boards 21 of the platforms are secured. The extending rear ends of these supporting beams are connected by the tie pieces 22, which serve to preserve the rigidity of the beams and also to limit the forward movement of the platforms. The floor boards 21 are preferably held by cleats 23, which are secured to the under sides of the boards, and strips or boards 24 are secured to the ends of the platforms by hinges 25 so that the same may be turned down between the platforms when in extended position, and so close the space between the ends of the plat forms and thereby prevent objects from accidentally dropping through, to the possible injury of workmen below.

In order that the platforms may be firmly held in place in any extended position, and also to prevent tilting of the platforms, bolts 26 pivotally secure locking strips 27 to the rear uprights 12, in position to be swung down with their lower ends contacting the supporting beams 20. Hooks 28 are secured to the locking strips 27 and are adapted to engage with eyebolts 29, suitably secured to the framework of the staging, thereby to hold the locking strips in elevated position and out of contact with the supporting beams. Cross braces 30 are secured to the rear uprights 12 for the purpose of strengthening the structure.

The side of a ship is indicated at 31, Fig. 1, for the purpose of illustrating the operation of the staging.

It will be noted that the platforms are spaced about three feet apart so that the workmen may work above the platform next above the one on which they are standing and so, when they come to operate from the one above, the work will be completed for a distance above such platform, and it will not be necessary for the workmen to stoop or kneel in order to perform their labor.

The platforms are, as will be understood, drawn out as desired to'bring them within a proper distance of the side of the ship, or other work, and the staging may thus be permanently erected in a ship yard and be suitable for use when any ship of usual dimensions is being constructed.

It will also be noted that, by working between alternate platforms, the platform be tween, which is drawn back out of the way, will form a guard to prevent workmen from accidentally stepping back off of the platform.

Having thus described the invention, what is claimed as new and sought by Letters Patent, is:

1. A staging comprising uprights, horizontally slidable platforms including supporting beams and flooring boards secured to said beams, said flooring boards being ca pable of passing between the uprights, means for preventing further forward movement of said platforms when they are in an extended position, and means for preventing movement of said platforms when they are in said extended position. 7

2. In a staging comprising uprights, horizontally slidable platforms including supported beams and flooring boards secured to said beams, said flooring boards being .capable of passing between the uprights, means for preventing further forward movement of said platforms when they are in an extended position, and boards hingedly con nected with the transverse ends of said flooring boards for abutment with the uprights to prevent rearward movement of said platforms when they are in said extended position.

3. In a staging, uprights, horizontally movable platforms including supporting beams, supported by the uprights, said platforms being disposed one above the other, pivoted locking strips adapted to engage the supporting beams for preventing tilting of the platforms, and means for restricting horizontal movement of the platforms, in one direction.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses. I

FRED C. MILTON.
