THOMAS BOYD, OF BOSTON, MASSACHUSETTS.
VENTILATING-GAP. FOR TENTS Application forming part of Letters Patent No. 33,068, dated August 2Q, 1861; Ressued July 2"?,
To all 'whom it may concern:
Be it known that T, THOMAS Born, of Boston, in the county of Suffolk and State of Massachusetts, have invented cert-ain new and useful Improvements in Tents, and that the following description, taken in connection with the accompanying drawings, hereinafter referred to, forms a full and exact specification of the same, wherein T have set forth the nature and principles of my said improvements, by which my invention may be distinguished from all others of a similar class, together with such parts as T claim and desire to have secured to me by Letters Patent- The gurcs of the accompanying plate of drawings represent my improvements.
Figure l is a central vertical section. Fig. 2 is a horizontal section taken in plane of line A, B, Fig. l. Fig. 3 is a detail view of the cap or covering.
It has always been very desirable in the manufacture of tents used for camp, or other similar purposes, to provide some suitable means for the ventilation of, and the production of currents of fresh air through, the same. If tents have no way provided for their ventilation, the inclosed air soon becomes foul and unwholesome and especially is this the case when they are pitched in hot and sultry climat-es.
The upper portion of the Vtent-canvas around the center pole thereof has sometimes been so arranged as to allow of the exit of smoke &c., but this could only take place during pleasant weather as the communicationwvith the external air was obliged to be cut off during rainy or other stormy weather in order to prevent rain &c. from entering. This it is evident is a serious dis advantage and therefore the object aimed at and secured by the present invention is to provide some suitable means for the ventilation of tents in wet, as well as in dry,-in stormy as well as in pleasant weather.
I accomplish the above desired result by attaching to the center pole of the tent,-in such a manner as to permit of its being raised or lowered at pleasure-a cap or covering made of a conical or any other desired shape which so covers and protects, as it were, an annular open space in the top of the tent around the pole, as to exclude the entrance of rain through the same, while alg lowing free ventilation-the draft of air j through the tent being regulated at pleasure by the raising or lowering of the cap.
c a in the drawings represent the center pole of the tent, I), o the canvas or any suitable water-proof material of which the tent may be made.
c, o, &c., CZ, cl, &c., are pins and ropes which secure the canvas to the ground in the usual manner. The upper portion of the tent-V canvas Z) is arranged so as to leave an open annular space .e around the pole a. To the ring f of the top portion of the canvas b are secured chains or cords g, g, &c., the other ends of which are attached to another ring L around the pole a. i
.i is a rope attached to the ring L which passing up over a suitable pulley in the pole a allows of the tent-canvas Z) being so raised or lowered as to tighten or loosen it as may, be desired.
y is a cap or covering made of a conical or any other suitable shape, the upper end of which is attached to the pole a of the tent over the opening e, in such a manner that by means of a rope 7c playing over pulleys Z, it (the cap) can be moved up and down and secured at any desired position upon the same. This cap or 'covering by being raised to its highest position, represented by dotted lines in Fig. l, allows of the free venand when it is lowered, in order to exclude rain &c. and prevent it from entering through the opening e, as represented in section, Fig. l, ventilation is still permitted through the space m left between the interior surface of the cap j and the exterior of the tent-canvas b--the diameter of the plane of the caps base being considerably larger than that of the tent-canvasV in the same plane. A metallic ring is placed in the base of the cap which causes it to lower, when the sustaining rope 7c is loosened, by its weight the cap j being made of canvas or any other suitable material. Thus it will be seen that by forming an open space around the pole of the tent in the upper portion thereof, and placing over the same, the cap constructed and operated as above described, the tent can be as thoroughly ventilated in wet as in dry-in stormy asin pleasant weather, for during rainy, or other stormy weather, the
cap being lowered, closes up as it were the 85 tilation of the tent through the open space c l/Vhat claim as my invention and desire to have secured to me by Letters Patent is- 15 A cap covering so arranged as to be susceptible of motion in a vertical or up and down direction, and so operating that the tent can be ventilated in both stormy and pleasant weather, substantially as herein 20 above set forth.
