TENT.

SPECIFICATION forming part of Letters Patent No. 701,126, dated May 27, 1902.

Application filed March 1, 1902.

To all whom, it may concern.-

Be it known that I, FRITZ BAHRMANN, a subject of the Emperor of Germany, residing at WVilhelmstrasse 127, Berlin, S. 7., Germany, have invented new and useful Improvements in Folding Tents, of which the following is a specification.

It is of greatimportance thathospital-tents and such as are destined for the temporary protection of invalids and convalescents in the open air can be readily pitched and struck-i. e., that the tent-walls, consisting of canvas or other fabric, can without difficulty be set up and again taken apart. At the same time the walls must be sufficiently rigidly and tightly connected with the framing posts or bars to afford adequate resistance to strong winds. In particular, the joints must be such as to prevent drafts or currents of air entering the interior of the tent. All these requirements are met by the tent forming the subject of the present invention, which is illustrated by the annexed drawings.

Figure 1 is a perspective view of a tent according to my invention. Fig. 2 is a sectional plan of such a tent. Fig. 3 is a detail view, drawn toa larger scale,illustrating the method of joining the tent-walls at the corners. Figs. 3 to 6 are sectional plan views illustrative of various methods of' forming effective walljoints. Fig. 7 is a similar sectional plan view showing a corner of a double-walled tent. Fig. Sis a perspective view showing another form of tent according to my invention, a post being here provided in the center of the entrance for the purpose of effecting secure closure.

The new tent is constructed of posts a stuck into the ground and having one or two longitudinally-running channels, grooves, or recesses 11 lying at the tent-corners. At the ends of the lengths of fabric forming the tent-walls w rods 0 c are provided, these be ing inserted into the channels or recesses of the posts a and secured by clip-bolts s.

The posts a may be of wood or, as shown in Figs. 2, 3, and 3, may be manufactured of iron tubes having semicircular recesses l) to receive the rods 0. Figs. 4 to 6 show posts made of channel, inverted-T, and angle irons, the rods 0 in these constructions Serial No. 96,292. (No modelJ being located in the angular spaces. The rods 0 are firmly held in place throughout their entire length in the longitudinal channels by means of the clip-bolts a, (the number of which depends upon the height of the tent,) Whose nuts are tightened from the interior of the tent, so as to make firm and tight joints. Owing to the sections selected for the posts a, great resistance is offered to bending.

The rods 0, on which the canvas or other fabric 20 is more or less rolled up, depending upon the distance of the frame-posts apart, are manufactured of wood, iron tubing, or the like and may be of round or angular section. When the tent is taken down, these rods serve to roll up the canvas on, so that the walls in this condition occupy the least possible space. By partly rolling up the canvas on the rods when the latter are being inserted into the post-groove the walls of the tent may be stretched to the required extent in the simplest imaginable manner, while the rolled portion of the fabric assists in making a perfectly tight joint.

As shown in Fig. 1, the sheet of canvas is divided at the entrance to the tent, the two parts being connected only at the top. a The roof to the tent consists of a separate piece of fabric 01, Fig. 1, according to its breadth hanging more or less over the lateral tent-walls and likewise provided with rods h for the purpose of securing it in position and of affording means for rolling it up.

When the posts are of round or other suitable section, they may be provided above with hinges, so that the top parts can be turned outward, as shownby the dotted lines in Fi 1, in order to form a ventilating-space for the entrance of fresh air.

The described construction can also be advantageously employed for garden and like tents which are taken down during the inclement seasons.

The tent-walls can also, as shown in Fig. 7, be made double, the same method of securing the canvas being adopted, so that the walls 20 and w inclose a layer of air between them. Air being a bad conductor of heat, such a tent is thus capable of being heated.

Various external forms, also in plan, may

be given to the tents, depending upon the particular purpose and the dimensions. Fig. 8 shows one form which may be adopted. Several tents can also be readily con nected either in the direction of the length or breadth.

The posts may be formed in two or more parts, the bottom portion being secured in the ground and the upper'portion connected to it by means of a socket or the like. In any case the tents can be'extremely rapidly and conveniently erected and taken down.

When a frame-post a is employed in the middleof the tent-entrance, as shown in Fig. 8, the latter can be tightly closed by merely loosely enveloping rods in the loose ends 6 e of the two sheets of fabric ff at the entrance and inserting the rods into the longitudinal grooves of the post a. The wrapped ends may also be connected with the fabric by means of buttons, books, or the like.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a folding tent, longitudinally-recessed frame-posts, rods fitting into the recesses and holding the ends of the tent-Walls, and adj ustable means for retaining said rods in the recesses,all substantially as and for the purposes herein set forth.

2. In a folding tent,longitudinally-recessed frame-posts, rods fitting into the recesses and holding the ends of the tent-walls, and clipboltsfpassing through said posts and retaining the rods in said recesses, all substantially as and for the purposes herein set forth.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

FRITZ BAHRMANN.
