Description
March 16, 1937. J. WOHLMEYE-R TRAVELING MOTOR COMPRES SOR Filed May 2, 1934 Patented Mar. 16, 1937 UNITED STATES Application May 2, 1934, Serial No. 723,593
In Austria December 2, 1933 4 Claims.
This invention relates to a new and improved motor compressor of the type driven by an internal combustion engine and adapted to travel as an'independent unit, and has for its object to. effect a very considerable saving of weight in the construction of such traveling motor com pressors.
In order to enable traveling or portable motor compressors, and more particularly the roadtraveling type, to be built with light weight it has hitherto been proposed to raise the speed at which the same works, and to provide a single crank shaft common to both engine and compressor.
A further reduction in weight has also been achieved in the designing of machines of this type by using the air receiver as a base on which to mount both the engine and the compressor, the engine being arranged with its crank-shaft parallel to the longitudinal axis of the air receiver cylinder.
In the known types of construction the arrangement is such that the longitudinal axis of the air receiver cylinder lies in the direction of travel of the unit, so that the axles of the road wheels are at right angles thereto, and skids or runners, if such be employed, are disposed parallel thereto. In either case special Outriggers or brackets must be provided for the trunnions of the road wheels or for the skids.
In accordance with the present invention the compressed air receiver is disposed with its longitudinal axis at right angles to the direction of travel, so that it is adapted to serve as a transverse bearer in the skeleton structure of the machine.
In accordance with the invention there is further attached to the air receiver the main frame which, in contrast to the hitherto known types of construction, can be made very light, since it is only required to carry the shafts or handles, the side walls or casinggand the cover or hood if such be used. The radiator and the fuel tank, the latter being arranged, if desired to take the place of a cover or hood, are mounted on this main frame, but subject the same to very little strain since they are mounted directly over the air receiver. These parts can also be mounted in the same position but directly attached to the air receiver.
By this novel arrangement the cylindrical air receiver, which is of very great strength in consequence of its shape, is made to serve as the backbone of the unit, so that the main frame and the axles can be made very light.
In consequence of the described principle of design which results in the crank-shaft of the compressor unit being disposed transversely of the traveling unit and the bulky air receiver well out of the way beneath the engine, the radiator can be placed closely adjacent the fly-wheel which can therefore be constructed as a blowerfan, with the result that the hitherto usual fan with separate drive can be dispensed with, thereby effecting a further saving of weight and increase in reliability.
The set of the air receiver transversely to the direction of travel enables the unit to be designed with such contours that it can easily travel over the usual obstacles, particularly hollows, ditches, and the like, without its progress being impeded by projecting parts. Protruding obstacles are also readily negotiated by virtue of the rounded shape of the cylindrical air receiver. The latter also prevents the unit from sinking too far into bog, sand, snow, and the like.
In place of or in addition to running wheels there can also be provided skids for the sliding movement of the unit and also to prevent the road wheels from sinking too far into soft ground. Skids of this nature can be used alone as a foundation for the unit when standing.
The construction according to the invention permits of the complete motor compressor being dismantled and taken apart into a few portable units, for example for mountain transport. These units form tidy packages which are not liable to become soiled or damaged. The parts can be reassembled simply and rapidly.
A form of construction embodying the invention is shown by way of example in the accompanying drawing, in Fig. 1 in side elevation, and in Fig. 2 in end elevation.
Fig. 3 is a plan view;
Fig. 4 is a central horizontal section through the compressed air receiver I and shows also the mounting of the wheel axle.
Referring to the drawing there is mounted on the cylindrical compressed air receiver which is disposed transversely to the direction of travel, the motor-compressor-unit 2 with its communal crank-shaft parallel to the longitudinal axis of the compressed air receiver I. To the two ends of the latter there are attached, either rigidly or resiliently, the trunnions 3' for the road wheels 4. Figs. 1, 2, and 4 show constructional examples in which the wheel trunnions or axle are supported resiliently, i. e., with the interposition o springs.
As shown in Fig. 1, a tube 1 I can be passed with packed joints lengthwise through the air cylinder, and, in the case of non-resilient mounting, the trunnions 3 may be attached to this tube. The two suspension springs [3 can either be attached to the ends of the cylinder, or, as shown in the drawing, can be articulated to brackets or the like I4 attached to the casing of the cylinder.
On the air receiver I there is further mounted the main frame 5 which carries the shafts 6, the side Walls and casing I, and the radiator 8. The fuel tank 9 is arranged to serve as a hood over the engine and compressor. The fly-wheel i2 is constructed as a blower fan. 7
To the frame 5 or to the air receiver 1 there can also be attached skids I0.
I claim:
1. A light weight traveling motor-compressor comprising in combination a cylindrical compressed air receiver disposed transversely of the direction of travel, a self-contained compressor unit consisting of an internal combustion engine having a fly-Wheel, a compressor coupled for direct drive by the said engine, and a communal crank-shaft for the said engine and compressor, the said compressor unit being rigidly and directly mounted on the said air receiver in such a manner that the axis of rotation of the said crank-shaft and the longitudinal axis of the said receiver are substantially parallel to each other,
a light framework likewise directly mounted on the said receiver and comprising a radiator disposed laterally of the said engine, guiding means at one end of the said framework, and a fuel tank on the upper part thereof substantially above the said receiver, and track wheels associated with the ends of the said receiver.
2. A light weight traveling motor-compressor as claimed in claim 1 in which the fly-wheel of the said internal combustion engine is disposed outside the crank-case of the engine adjacent the said radiator and is constructed as a fan to set up forced draught through the said radiator.
3. A light weight traveling motor-compressor as claimed in claim 1 in which the said track wheels are resiliently mounted on the ends of the said receiver.
4. A light weight traveling motor-compressor as claimed in claim 1, further comprising a ho]- low tubular member disposed longitudinally inside the said air receiver from end to end thereof, tight joints between the said member and receiver, springs associated with the ends of the said receiver, an axle attached to the said springs and extending through the said tubular member, the said track wheels being mounted on the ends of the said axle.
