Application January 24, 1958, Serial No. 710,993

1 Claim. (Cl. 37-53) This invention relates to improvements in snow throwers and more particularly to a modification of the snow thrower described in my prior application of September 24, 1956, bearing the Ser. No. 611,477.

An object of the invention is to provide a device of the type which is so constructed that it will enter freely into snow which is to be thrown to one side or the other by the machine.

Another object of the invention is to provide novel means for setting the gates on the front of the device.

Other and further objects of the invention will appear as the description proceeds, reference being had to the accompanying drawings, in which:

Fig. 1 is a side view in elevation of a snow thrower embodying the invention.

Fig. 2 is a top plan view thereof.

Fig. 3 is a fragmentary inverted plan view.

Fig. 4 is a vertical sectional view taken on line 44 of Fig. 5.

Fig. 5 is a front view in elevation of the fan blade mechanism.

Fig. 6 is a fragmentary vertical sectional view taken on line 66 of Fig. 4.

Referring more particularly to the drawings, the numeral 10 refers to the device generally, including a frame 11 which is supported by the ground-bearing wheels 12 on the axle 13. The

handle members

14 and 15 are also afiixed to the frame 11. A supporting bracket 16 extends upwardly and forwardly at an angle from the frame 11 to which it is secured by threaded means 17 and 18. The fan or reel casing 19 is pivoted for limited movement about a vertical axis on the

bolts

20 and 21 and has afiixed rearwardly thereof, the sector plate 22 apertured as at 23 to receive the detent 24 normally urged do'wnwardly by the spring 25 and withdrawable by means of the rod 26 and the handle member 27. The detent 24 is slidable vertically in the housing 28 which is carried on the plate 29 welded at 30 to the frame 11 as shown in Fig. 4.

Side members

31 and 32 support a platform. The engine 33 is pivoted at the rear lower portion thereof by means of the rod 34, and may be raised and lowered frontally by means of the pull rod 35, the lever 36 and the roller 37. The engine crankshaft 38 carries a pulley to accommodate the belt 40 engaging the pulley 41 on the jack shaft 42.

ice

A gear 43 on the jack shaft 42 carries the chain 44 Which is in mesh also with the gear 45 on the reel axle 46 journalled in

side walls

31 and 32 and the

bearings

47 and 48. The axle 46 carries the blade arms 49 and the arcuate blades 50. The reel casing 51 is provided with a pair of forwardly disposed hinged

members

52 and 53 which are maintained in parallel alignment with each other and the wheels 12 by means of the aligning mechanism 54 provided with the spring detent 55. The aligning mechanism 54 comprises a pair of uprights 56 affixed to the forward leaves 57 of the hinges 58. The uprights 56 are provided with the rearwardly directed horizontal arms 59 pivotally connected with the transverse bar 60. A fork element 61 carries the spring detent which may be inserted into any one of the apertures as at 63 of the transverse bar 60, thus fixing the position of the hinged

members

52 and 53 and the front wheels 64 which are mounted thereon by means of axles 65.

In use, the operator starts the gasoline engine 33 in the usual manner. The handle 27 is pulled to withdraw the detent 24, and the

handles

14 and 15 are moved to the right or to the left as desired, whereupon the detent is allowed to secure the sector plate 22. The reel casing 19 will now be biased relatively to the rear wheels 12. The front wheels may then be aligned with the rear wheels by manipulating the aligning mechanism 54 and securing the spring detent 55. It will then be understood that the snow will be thrown forwardly of the reel casing but to one side or the o'therof the path of the machine, as has been selected by the operator.

It will be understood that the device is capable of many modifications in structure and design, without departing from the spirit of the invention, within the scope of the appended claim.

Having thus described the invention, what is claimed and desired to be secured by Letters Patent of the United States, is:

A sno'w thrower comprising a frame, a reel casing mounted thereon for limited rotative movement about a vertical axis, hinged plates extending frontally of the side walls of said casing, upright rods projecting upwardly therefrom, a horizontal bar projecting rearwardly fixed to the top of each of said ro'ds, a crossbar pivoted to and connecting the rear ends of the horizontal bars, a fork pivoted to one horizontal bar and embracing the crossbar with its opposite end, and a releasable detent for fixing the fork to the crossbar in a selected position to align said hinged plates, a vaned reel in said casing, and an engine mounted on the latter as a source of power for said reel.
