2 Claims.
This invention relates to an improved motorized mono-wheel game and pack carrier of the type disclosed in my copending application Serial No. 114,860, for use by hunters and others, the primary object of the present invention being to provide a practical and serviceable device of this character which enables easier and more efiicient carrying of relatively heavy loads of game, hunters packs, and the like, over rough and hilly terrain, as well as over level ground, with a minimum of effort and fatigue.
Another important object of the invention is to provide a carrier of the character indicated above which is provided front and rear with handles for pushing, pulling and maneuvering the carrier over the ground, with the single, centered, ground engaging wheel positioned substantially midway between the ends of the carrier, and with the motor mounted at the front of the carrier in such a way that the carrier is Weighted to have a tendency to tilt forwardly, thereby facilitating working the carrier up a hill by an attendant grasping the front handles, and further, facilitating the task of a second attendant grasping the rear handles.
A further important object of the invention is the provision of a carrier of the above-indicated character wherein the controls for the motor are located on the front handles to be operated by the attendant grasping the front handles, thereby affording better control of the carrier in working over rough ground and up hills.
A still further important object of the invention is to provide a carrier of the character indicated above, wherein the motor can be disconnected from the mono-wheel, whereby the carrier can be used as a manually operated carrier when desired.
Other important objects and advantageous features of the invention will be apparent from the following description and the accompanying drawings, wherein, for purposes of illustration only, a specific embodiment of the invention is set forth in detail.
In the drawings:
Figure 1 is a general left-hand side elevation;
Figure 2 is a top plan view;
Figure 3 is a bottom plan view;
' Figure 4 is an enlarged, fragmentary, top plan view of the gear shift lever;
Figure 5 is an enlarged, fragmentary, tive view of the motor frame;
Figure 6 is a fragmentary, left-hand, side elevational, detail showing the arrangement of the shield behind the motor;
perspec- Figure 7 is an enlarged, fragmentary, transverse, vertical section taken on the line 'I--'! of Figure 3;
Figure 8 is an enlarged, fragmentary, transverse, vertical section taken on the line 8-8 of Figure 3.
Referring in detail to the drawings, wherein like numerals designate like parts throughout the several views, the illustrated carrier comprises a longitudinally elongated, horizontal carrier frame l0 comprising straight, parallely spaced side members II, II preferably consisting of light weight metal pipes or tubes, having their ends bent up at right angles at E2 and inserted and secured in the lower ends of vertical tubes l4, into whose upper ends are inserted and secured the downturned portions lb of forwardly and upwardly projecting front handles 16, and rearwardly and upwardly projecting rear handles ll, both sets of handles involving tapered, cylindrical grips l8 terminating in rounded ends IS. The rear handles I I are pivoted to turn inwardly when desired, as shown in dotted lines in Figure 1.
The side members II are spaced and rigidly connected at their front ends by the motor frame comprising a front angle iron 2|] and a rear angle iron 2! spaced a short distance behind the front angle iron 20, the horizontal flanges of the angle irons resting upon the tops of the side members and being traversed by bolts 22 traversing the horizontal flanges 23 and portions 24 of pipe clamps 25 hooked under the side members l I from the outer sides of the side members, as shown in Figure 8. The angle irons 2i) and 2| are, as shown in Figure 5, spaced and rigidly connected together by laterally spaced straps or bars 25', 25' formed with holes 26' to receive bolts (not shown) for securing the motor 21 to these bars between the angle irons 2t! and 2!.
Immediately behind the vertical flange 28 of the rear angle iron 20 is secured the perpendicular shield 29 in the form of a rectangular plate extending across the carrier frame Ill and rising thereabove to a sufficient height to protect the motor 21 from being contacted by loose or incompletely packed material on the carrier frame.
Behind the shield 29 the carrier frame side members H are spaced and rigidly connected together by a plurality of boards in the form of relatively rigid, transversely elongated plane and rectangular plates 3|, 32, 33 and 34, respectively. These boards are spaced from each other along the carrier frame [0, and the rearmost board tudinal dimension than and 34, and covers the middle area of the car 3 34 has its rear edge at the rear ends of the side members H.
As shown in Figure 1, each of the boards underlies the carrier frame side members H and is fixed thereto by means of two J-bolts 35 at each end having shanks 36 traversing the boards at the inward sides of the side members H with their hooks 31 engaging over the side members. In addition the front plate 31,, and the next to rear plate.;33;;, hasq a pipe clamp 35': ateach end between the J-clamps 35 welded thereto and engaging over the tops of the side members IL;-
