Similar reference characters refer to similar parts throughout the several views of the drawmgs.

Having reference now to the drawings, there .is generally indicated at ID a motor vehicle of any desired type, and provided with'a truck' body ll, within which is contained a turbine or similar pumping device, generallyindicated at 12, and including a casing with rotor i 3 therein (see Fig. 4), and having an inlet l4 in alignment with the vehicle body and an outlet l5, preferably extending through asuitable opening in the roof of the truck body I l. The turbine I3 may be driven by the motor of the. vehicle, or in any other desired manner. Adoor lB'is the side of the body II provides access to the 'turbinefor repairs'as maybe necessary.

Suitably secured to the inlet l4 of'thetturbine is a tubularventilating member l8, comprised of canvas, fabric, or rubber tubing, having a plurality of metallic reinforcing ringsi9 positioned interiorly thereof for the purpose ofniaintaining the same in expanded position when suction is exerted therethrough "by means of the exhaust turbine l2. As best shown in Figures 6 and 7, the outer extremity of thetube I 8 terminates in a rectangular member or plate 20, provided with a circular aperture 2'l, to which the outer end of the tube i8 is adapted to besecured. The member or plate 20 is provided on its inner side with oppositely disposed handles 22, that is, on the side adjacent the tube I8, and on its outer side adjacent the upper extremity thereof with a pair of angularly disposed extending prongs 2 3, the purpose of which will bemore fully discussed hereinafter. A bracket'member '24'is provided on the lower extremity of the member 20 beneath the tube [8.

Means are provided for securing the tube I8 and its associated end member 20 in relatively close juxtaposition 'to the inlet of the turbine l3,

such means taking-the form of arcuate members 25 pivoted at'three points, as at 26, to the front wall of the turbine casing. The members 25 are positioned, as best shown in Figure 5, at a substantially spaced distance from the inlet 14 inorder that the entire length of the tubing, when contracted, may be contained therewithin, and the extremities 210i the arcuate members 25 engage over the edges of the member 20. In order to facilitate free pivotal movement of-the members 25 and provide a locking device, extensions 29 extend therefrom to the pivot points 26, and the central extension 29 is pivoted, as .at 30, to each of the arcuatemembersVZS. Extensions 29 are slidable friction clamps for securing arcuate members 25 in any desired position. It will now be seen that when the members 25 are moved from the positions disclosed in Figure 11, the member 20 being retained therebehind, that the entire tube assembly may be contained within the body ll of the truck. The specific structure of the sliding clamp means may be seen best in Figure 13, wherein there is disclosed a rod 3| slidably received and frictionally retained in a tube 33. The tube is pivoted at 26 to suitable brackets, while the rod 31 is pivoted to the aforementioned member 25. Friction between the telescopic members 3| and 33 retains the arcuate member 25 in a selected position. It will be seen, correspondingly, that any desired length of the tube l8 may be removed from the vehicle by displacement of the members 25, and, after the desired amount has been paid out, the members 25 moved inwardly to the position disclosed in Figure 4, and clamped between any two of the rings I9, thus retaining the balance of the tube within the truck body.

When utilized alone, as in conjunction with a small window, or the like, the member 20 is placed within the window, the handle 22 being utilized for such purpose, and the projections 23 engaged beneath the upper sill thereof, and the lower portion thereof held in position, as by means of a spike or the like inserted in the bracket member 24.

Means are also provided for utilizing the device in association with a large door, or the like,

such means taking the form of a supplemental door .or mounting frame 35(see Figures 2 and 3), provided adjacent its upper portion with an aperture 36, extending into which are lugs 31 adapted to engage the upper extremity of the member 20. The mounting frame 35 is provided with elongated'handle members 38 adapted forthe suitable positioning of the same; and has, in'its lower portion below the aperture 36, a hinged door 39 to permit access to the building, or the like, within the center of which is hinged a smaller 'door 40 of a dimension to permit the insertion of a fire hose nozzle, or the like. Suitable latch means 4| are provided for holding the door 39 in closed position; Means are also provided for securing the mounting frame 35 within a door frame, or the like, and such means take the form of hook members extending through the inner side of the door through suitable apertures, of a relatively great length in order to accommodate varying thicknesses of wall. The inner threaded portions are provided with rotatable wheels 46, adapted to be tightened when the hooks are flared outwardly in desired position within the door frame to hold the same in relatively tight related assembly with relation thereto.

Asb'est shown in Figures 9 and 10, means are provided forextending the height of the door in order to fully close relatively high door frames, such means taking the form of an extension 49, provided with depending tongue portions adapted to engagein suitable brackets 5! on the upper extremity of the mounting frame 35.

When it is desired to remove smoke or gas, or similar fumes from a building, the frame 35 is first removed from the rear of the truck with which it is normally associated, the truck being moved as close to the building as convenient, and secured in position either with or without the extension 49, by means of the hooks 45. The truck is then moved to a suitable distance, the tube I8 being paid out as the truck moves away, or alternatively previously fed out by hand, as may be most expeditious, and when suitably tautened at a requisite distance from the building, the exhaust turbine is started and a powerful suction set up within the tube, and, correspondingly,

is of sufficient dimensions to admit a man into the. building whilethe frame is in place, while the door 30 is of .sufiicient dimensions 'topermit the passage of afire hose readily therethrough. C'orrespondingly, as above pointed out, in the event that only a small aperture is available, the member or plate 20 maybe utilized alone, by

i detaching the same from theunountin'g. frame 35.

From the foregoing, it will now be seen that there is herein provided an improved mechanical ventilator readily transportable, and adapted for the ready ventilation and removal of fumes, gases, smoke, or the like, from any desired location, Which accomplishes all of the objects of this invention and others, including many advantages of great practical utility and commercial importance.

As many embodiments may be made of this inventive concept, and as many modifications may be made in the embodiment hereinbefore shown and described, it is to be understood that all matter herein is to be interpreted merely as illustrative and not in a limiting sense.
