IVMPROVEMENT'IN VENTILATINGIWINDOWS FOR TENTS.

Specification forming part of Letters Patent No. 35,963, dated July 272, 1862.

To @ZZ whom it may concern:

Be it known that we, HENRY WARNER and BENJAMIN F. PALMER, both 'of the city of l Boston, in the county of Suffolk and C0mn1onwealth of Massachusetts, have invented a new and useful Improvement in Tents; and we do hereby declare that the following specification, taken in connection with the drawings making a part of the same, is a full, clear, and exact description thereof.

Figure l is a perspective view of the tent, showing one of the ventilators open and the cowl raised. Fig'. 2 shows the flap closed which forms the door. Figs. 3 and 5 are views of two' varieties of tent-poles, either of which `may be used with our tent. Fig. 4 exhibits the appearance of the apex of the tent when the cowl is down.

The variety of tents now in most common use in the United States Army is the one invented by H. H. Sibley, and known generally by his name. This tent is provided with a cowl or a secondary covering` for the apex; but

Ait is distinct from the tent itself, and is capableof being adjusted so as to effect ventilation only from the outside, thus involving the necessity of considerable trouble to accommodate the opening at the peak to any change in the direction of the wind.

The first part of our invention consistsin an arrangement for Ventilating the tent by the use of a cowl or hood, which is permanently attached to the tent,and which can be readily operated by any person from the inside in sucli a manner as to cause the top of the tent to be open toward all points ofthe compass,or open only toward such points as are desired..

A, Fig. l, represents a conical tent of the usual size, its base being eighteen feet in diV ameter and its height thirteen feet. It is secured to the ground by loops n and tent-pins m,in the usual way, and is provided with the vwell-known ilap extending around the base,

upon which sods of earth can be heaped to exclude a draft of air at the bottom. The tent `is sustained, when pitched, bya single central pole,Figs.3 or 5,presently to be described. The

Y upper extremity of the pole terminates with of ventilation, but the size as well as the num-V ber can be increased, if desired. A hood, C,

securely sewed to the tent near the apex', ex-

tends down below the openings h and effectually closes them, as shown in Fig. et. The cords g g g, hanging by the side of the tentpole at a'convenient height to be seized by the hand, pass through eyelet-holes e e e, Fig. 5, near the apex in the canvas of the tent proper, and are led through rings or eyes attached tothe under side of the cowl to a point below the edge of the cowl, passing through eyes b b on the outside of the tent a convenient length-say two or three feet--at which points weights a a a are attached to them. Each cordis securely fastened to the edge of the cowl, so that as the cord is pulled from the inside of the tent the edge of the cowl will be raised above one of the openings. If all the cords are pulled, the cowl will be gathered about the apex in the form shown in Fig. 1, forming a sort of wind-sail or awning over each opening,

while a free passage for the exit of air or smoke is allowed. As each cord is relaxed the weights a a a, attached to the other end, draw back the cowl over the openings which have been uncovered. It is evident that by this arrangement the tent can be Ventilated in any direction with the greatest facility, or the opening changed from one side to the other without any more trouble than is involved in operating the cords gg g.

The second part-ot' our invention consists in an improved window, I, Fig. l, so arranged that the size of the aperture can be regulated at pleasure from vthe inside of the tent, and which, when closed, shall effectually exclude both stormsand wind. The elliptical openings I, opposite to .each other, are cut in the of the side iiaps and about four inches from the end ofthelong diameter, a Hap, J, is sewed to the wall of the tent on all sides, except the lower one. The shutter D .of sufiicient size to cover the window, isprovided with a number of clasps, t t t, which span the Weltcd edges of the side flaps and enable the shutter to be slid up and down over the aperture. A cord, q, attached to the upper extremity, and another cord, 1',attached to thelower extremity of the shutter,pass through eyelets in the canvas ofthe tent, as showinso that by pulling the cord q from the inside the shutter is drawn up underneath the fiap J and the aperture completely closed. By operating the cord r the shutter can be opened.

The third part of our invention consists of an improved tent-pole capable of being adjusted to different lengths to accommodate the variations in the length of the canvas. It consists of two parts, E and G, Fig. 5, the rst part of tough wood and the second part of metal. The upper part, E, is provided with a metallic shank, VH,in which are a series ofholes at small distances apart. This shank is fitted to slide freely in the cylindrical part G, which is also provided With a series ot' holes lcorresponding to the holes in the shank. Upon the upper end of the socket G, placed so as not to interfere With the movement of the shank H, is afulcrum-arm, U. A rod of steel, which at other times can serve as a crane upon which to hanga kettle,is now inserted in one of the holes in the shank H,and being used as a lever with U as a fulerum the canvas can be strained to any tension desired. A pin,attached bythe chain J to the socket G, is now inserted into any hole under the shank H which happens to coincide with one of the holes in the socket, and the length of the pole is determined.

Instead of constructing the pole so that one part of it shall slide inside the other part, we contemplate sliding the two parts upon a scarf-joint, as shown in Fig. 3. The end of a rope or strong cord is passed through a hole near the lower end of one of the parts and knotted on the outside. The rope isthen're-Y ceived through a hole or block near the eX- tremity of the other part, a groove being cut in the faces which arein Contact to accommodate the rope. Two bands of iron, P I), embrace both parts, the bands being made fast to the part F only. It is apparent that by this arrangement the saine effect will be produced as by the one above described.

What we claim as our invention, and desire to secure by Letters Patent, is*

1. A secondary hood or cowl attached to the canvas of the tent near the apeX,where the same is so arranged that it can be raised atV
