FOLDING FRAME FOR PORTABLE BUILDINGS.

Specification of Letters Patent.

Application filed April 26, 1915. Serial No. 23,959.

5 respectively, residing at Racine, in the county of Racine and State of Wisconsin, have inventedv certain new and useful Im--.

provements in FoldingFrames for Portable Buildings, of which the, following is a specification, reference being bad to the accom- I panying drawing, forming a part thereof.

This invention relates more particularly to frames for tents'or canvas covered buildings. The main objects of-the invention are to provide a light folding frame which can be easily and quickly erected, taken down, folded and packed in small compass for transportation and storage; when taken down has few disconnected parts or detached fastenings be misplaced and lost; and generally to simplify and improve/the construction and increase the convenience and utility of col- 2 lapsible portable buildings of this class.

It consists in the construction, arrangement and combination of parts as hereinafter particularly described and pointed out in the claims.

In the accompanyin acters designate the same parts in the several figures. Figure 1 is a perspective View .of a twobent or section frame embodying the invenbeing shown erected ready for a canvas or other covering; Fig. 2 is a side elevation on a' much larger scale of the superstructure or upper part of the frame when folded; Fig. .3 is a similar elevation of an adjacent side of the folded frame; Fig. & is a side elevation on an enlarged scale of the folded base orsill frame; Fig. 5 is a similar elevation of an'adjacent side of the r Fig. 6 is an enlarged side detachable door post and folding top rail; Fig. 7 is an enlarged elevation'of one of the detachable tie braces for connecting the rafters; Fig. 8 is an end elevation as viewed from the left relative to Figs. 2 and 3, of the folded main frame; Fig. 9 is an elevation of the opposite end of said folded frame; Fig. 10 is an enlarged detail view in perspective of the hinge connections between a corner post rafter and folded sill frame;

the superstructure or main frame comprises

posts

1, 2, 3, 4, 5 and 6,

rafters

7, 8, 9, 10, 11 and 12,

plate members

13, 14,15 and 16, and

ridge pole sections

17 and 18, which are connected b'y hinges so as and 9.

The building may have, especially if it is to be provided with a floor, a separate folding base or s'll frame. This frame is composed of

sections

19, 20, 21, 22,223,2 1,

to fold together into a small compass, as shown in Figs. 2, 3, S

ends by angular hinge plates 0, which are also preferably flanged and riveted or bolted to opposite sides of the posts, as shown in Figs. 1, 10 and 11, the offset limbs of the plates embracing the rafters being pivotally connected therewith by hinge pins d.

The

plate members

13, 14, l5'and 16-are connected at their outer ends with the lower ends of the

end rafters

7, 8, 11 and 12, by L-shaped hinge plates 6, whichware riveted or bolted to the upper and lower sides of the rafters, as shown in Figs. 1 and 10, the offset limbs of the hinge plates being pivotally connected with the plate members by hinge pins f. The inner ends of the

plate members

13, 14, 15 and 16 are connected with the lower ends of the intermediate rafters 9 and 10 by T-shaped hinge plates g, which are riveted or bolted to the upper and lower sides of the rafters, as shown in Figs. 1 and 11, the cross limbs of the hinge plates being pivotally connected with the plate members by hinge pins h. I

The

ridge pole sections

17 and 18 are connected adjacent to their outer ends with the upper ends of the

end rafters

7, 8, 11 and 12, by forked hinge plates 13,. which are attached to the inner ends of the hinge pins 6 and are pivoted to said sections by cross pins j, as shown in Figs. 1 and 12. At their inner or opposite ends the

sections

17 and 18 are provided, as shown in Fig. 13, with fastenings for connecting them in alinement with each other when the frame is erected, as shown in Fig. 1. These fastenings consist of a looped plate It, riveted or bolted to the sides of one section, and a downwardly hooked plate Z riveted or bolted to the top of the other section and adapted to be inserted from above into the'loop'ed end of the plate is. The upper ends of the several rafters are beveled to fit against opposite sides of the ridge pole and to embrace and firmly support the same, as shown in Figs. 1 and 12, when the members are unfolded into place in the erection of the frame. The sill sections are connected at the corners of the frame, as shown in Figs. 1 and 18, by box-like or channeled hinge plates or members m, which are bolted or riveted to said sections and are formed with inwardly projecti'ng offsets connected by hinge pins n. The webs and lower flanges of these hinge sill sections and form sockets or holders for the lower ends of the

corner posts

1, 2, 5 and 6. The

end sill sections

19, 20, 23 and 24: are provided at their inner ends with hinge plates 0, riveted or bolted to the upper and lower sides thereof and formed with outwardlyprojecting offsets or ears, which are pivotally connected with each other by vertical pins p, as shown in Fig. 15. The

side sill sections

21, 22, 25 and 26, are provided at their inner ends with hinge plates 9, riveted or boltedto opposite sides thereof and formed with upwardly projecting offsets or ears, which are connected by horizontal pivot pins 7", as shown in Fig. 14. The plates q extend beyond the ends of the sill sections and form with the ends thereof, sockets or holders for the lower ends of the middle posts 3 and 4.

The frame is preferably braced and strengthened as follows:

Tie braces

27, 28 and 29, beveled at the .ends, as shown in Figs. 1 and '7, to fit the under sides of opposite rafters are detachably fastened thereto as shown in Figs. 1 and 17, by bolts 8 and thumb nuts 6. Jointed metal corner braces 30, are pivoted at the ends tothe under sides of the

end rafters

7, 8, 11 and 12, and

plate members

13, 14, 15 and 16, equidistant from the corners of the roof frame, as shown in Fig. 1, so as to fold therewith, as shown in Fig. '3. Post braces 31, pivoted to the. sill sec-' tions are detachably connected by bolts and thumb nuts u with the posts above their lower ends. These braces, which are provided at their lower ends with U-shaped metal fittings '0, may be pivoted to the inner sides of the sill sections, as shown in Fig. 1, by bolts w, passing horizontally through the fittings and sill sections, so as to fold with said sections, as shown in Figs. 4 and 5. This is the preferable method of connecting the braces w1th the sillframe, so that they will readily fold therewith and need not be detached therefrom, but when the building is provided with a floor laid on the sill frame, the braces may be pivotally connected with the tops of the sill sections, as shown in Fig. 19, by passing the bolts to through holes in the ends of the fittings o and through vertical holes in the sill sections, the braces then pivoting on the pins 0', by which they are attached to the sides of the fittings o, and not as before, on the bolts w. With this method of connecting the braces with the sill frame, the fittings o with the bolts w are preferably removed from the frame when the building is erected, and the bolts are then inserted through holes in the floor registering with the holes in the sills, thereby clamping the floor to the sills and avoiding the necessity of cutting away the flooring to clear the fittings '1).

At one end the frame is provided with a door post 32, detachably fastened at its ends to an end sill and tiebrace, as shown in Fig. 1. Oneof the braces 31 is connected with the post 32 instead of the adjacent corner post 1. A top cross rail 33, for the doorway,

is connected. at one end by L-shaped hinge plates on, with the door post 32, as shown in Figs. 1, 6 and 16, so as to unfold at right,

angles to the post, as shown in Figs. 1 and 16, and to fold parallel therewith, as shown in Fig. 6. The opposite end of the cross rail '33 is beveled to fit into the opening between the upper end of the adjacent post 1, rafter "7 and hinge plates 0, when the frame is erected, as shown in Fig. 1, the upper end of the post 1 being cut off square for this purpose. At its lower end the post 32 is provided with notched or slotted plates y, riveted or bolted to opposite sides thereof and adapted to embrace the sill section 19 and engage with a cross pin 2 therein, as shown in Figs. 1 and 16. At its upper end the post 32 is provided with an angular plate bolted or riveted thereto and have ing a slot and notch in its offset limb for engagement with a bolt and thumb nut a by which it is-clamped to the tie brace 27 when the frame is' erected, as shown in Fig. 1. This bolt and thumb nut a may serve also, likethe bolts 8 and thumb nuts t to fasten the brace 27 to the rafter 7.

- vThe frame may be made with one or more bents or sections for buildings of different sizes and for adding a bent or section atone end of the frame, the hinged end of the ridge pole section 18 is provided with an upwardly projecting hook Z adapted to engage with' a looped or U-shaped plate is! fastened to the free end of the ridge pole section 34 of the additional bent or frame sectidn, as shown in Fig. 20, and the plate members 35 of the added bent or frame section are connected with the

plate members

15 and 16 by hinges 36, as shown in Fig. 21.

A two-bent frame having abase or sill frame, as shown in Fig. 1, is taken down and folded as follows: The braces 31 are detached from the several posts with which they are connected at their upper ends by removing the thumb nuts 1, which are then replaced on the bolts remaining in' the posts,

.toavoid their being misplaced and lost.

' The door post 32, with the top rail 33, are

removed from the frame and folded together, as shown in Fig. 6, the thumb nut e 1 tie brace 27.

being tightened and left on the bolt in the The tie braces 27, 28 and 29 are-removed from'the rafters by unscrewing the nuts t from the bolts 8, which to prevent their being misplaced and lost, and to permit the frame members to fold snugly together, are preferably withdrawn from the I rafters and replaced in the holes in the braces. The

ridge'pole sections

17 and 18, are disconnected at their inner ends, re-

- moved from the middle rafters 9 and 10, and

turned downwardly on the hinge pins j. The

posts

1, 2, 3, 1, 5 and 6' are then withdrawn from the sockets in the base or sill frame and folded underneath the rafters, which are then folded with the posts between them on the hinge pins 6. The end rafters with the end posts are then folded around the hinge pins f upon the

plate members

13, 14*, 15 and 16, and with said members are folded on the hinge pins it against and parallel'with opposite sides of the intermediate rafters 9 and 10 and intermediate posts 3 and 4.- into the form shown in Figs.

2,3,8and 9.
