LOGGING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 525,944, dated September 11, 1,894.

Application tiled November 9, 1893. Serial No. 490,428. (No model.)

To a/ZZ whom it may concern:

Be it known that I, ANDERSON W. BROWN, of Rhinelander, in the county of Oneida and State of Wisconsin, have invented a new and Improved Logging Apparatus, of which the following is a full, clear, and exact description.

My lnvention relates to improvements in an apparatus which is primarily designed for drawing logs over icy roads, although it may b e used for drawing other material. In logging countries where my apparatus is to be used, the road is made icy by sprinkling water on it and permitting the water to freeze, after which ruts are cut in which the runners of the sleighs may run.

The object of my inventionis to produce a simple apparatus which is adapted to run on roads of this kind and draw after it heavy loads, and which is provided with a series of legs operated by a motor ou the apparatus and adapted to engagev the ice in the road and push the apparatus forward, the legs being arranged so that some of them will always be pushing and so that they will push evenly and cause the apparatus to go straight ahead. f

To these ends my invention consists of certain features of construction and combinations of parts, as will be hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in both the views.

Figure l is a plan View of the apparatus embodying my invention; and Fig. 2 is a longitudinal section on the line 2-f2 of Fig. 1.

The apparatus is provided with a sleigh which may be of any ordinary construction, either after the form of common bob-sleighs or single sleighs, and on the sleigh is a bed frame 11 which carries transverse shafts 12 and 13, these being mounted in suitable bearings 14 and these shafts are provided with Sprocket wheels 15 which are connected by a chain 16, and one of the shafts is provided with a crank wheel 17 which connects by means of a pitman 18 with an engine 19 which may be of any approved form and which,together with its .boiler 20, is mounted on a platform 21 carried by the bed frame 11.

Each shaft 12 and 13 is provided with a series of eccentrics 22, these being differently arranged on the shafts, as shown in the drawings,'and the eccentrics are encircled by the usual eccentric straps 23, which are formed on rearwardly projecting legs 2l, each leg terminating at its rear end in a foot 25 which is somewhat larger in cross section than the body portion of the leg to prevent it from clogging; and each footis provided with a swallow-tail cut which forms a toe 26 adapted to engage the ice in the road, and this toe may be a part of the leg or may be inserted or adjustable and fastened to the leg. This arrangement of the foot causes it to readily dig into the ice and it provides for clearance,

so that the foot cannot become clogged and inoperative.

The eccentrics are arranged in pairs, that is, so that two eccentrics at equal distances from the center of the shaft will, at the same time, actuate the legs connected with them so as to cause two feet, at equal distances from the center of the sleigh, to simultaneously engage the ice and thus prevent the sleigh from slewing. The eccentrics on the two shafts are also arranged with relation to each other, so that at all times two feet will be pushing on the ice, and the angles of the legs are such that the legs will not shift on their shafts to any appreciable extent, but will have a tendency to throw the sleigh 10 forward.

The sleigh 27 or a train of sleighs may be coupled to the rear end of the sleigh 10 and loaded with logs 28, so that when the sleigh 10 is propelled alarge quantity of logs may be drawn after it.

It will be seen that when the engine is set in motion the legs 24: will operate in pairs, one pair after the other, so that the whole apparatus will be propelled, and it will be understood that the apparatus may be pushed over any ordinary winter road, that the sleigh and the bed frame may be of any approved construction, that any suitable motor may be used for working the legs, and that the load may be attached to the sleigh 10 in any convenient manner without aifecting the principle of my invention.

Having thus fully described my invention, I

IOO

claim as new and desire to secure by Letters Patentl. The combination with a sled, and motor mounted thereon, of two shafts mounted on the sled, each shaft being provided with a sprocket wheel at one end, and one of them with a crank, a chainpassing around the sprocket wheels, a pitnian connecting the crank with the motor, eccentrics arranged in pairs on each shaft, and legs having straps at their upper ends encircling the eccentrics and provided with feet at their lower ends, substantially as described.

2. The combination with a sled, an engine mounted thereon, two shafts mounted on the Vthe shaft and legs having straps at their upper ends encircling the eccentrics and pro vided with feet at their lower ends, each foot being provided with swallow-tail cut forming a toe, substantially as herein shown and described.
