Specification of Letters Patent.
Patented May 30, 1922.
Application filed August 30, 1920. SeralvNo. 407,051.
To (/,ZZ '107mm t may concern.'
Be it known that I, Gnonen lV. lvns, a citizen of the United States, residing at Milwaukie, in the county of Clackamas and State of Oregon, have invented a new and useful Sled for Donkey Engines, of which the following is a specification. l
My invention relates to improvements in sleds for donkey engines, in which the runners of said sleds are connected by meansof concrete platforms or slabs.
ln our modern lumber camps, where l'ogging operations are conducted on a gigantic scale, it has so far been impossible to construct a sled for the donkey engine which will successfully withstand the wear and tear.
The objects of my invention are to construct a sled which is so solidly connected that diagonal stresses are wellnigh impossible, which holds the engine rigidly in place, and which can be constructed with material easily obtainable in a logging camp.
l attain these objects with the mechanism illustrated in the accornpanyin,j drawing, in which- Fig. l is a plan view of the entire sled.
Fig. ll is a side elevation of Fig. I.
Fig. UI is a sectional end elevation of Fig. I along the line A--r Similar numerals refer to similar parte throiie'hout the several views.
After the logs or runners 1 have been .leveled off to afford a smooth and even bearing for the machinery l, (indicated by dotted lines in Fig. Il), and after the mortiscs hare been cutvinto the sides of the runners, the latter are connected by the bolts thick concrete slab -i is then poured between the runners at cach end` whereby the hardened concrete, shaping itself closely to the unerenness of the logs, entering the n'lortiscs, and gripifiing the boltsl firmly, constitutes a braueeiwhich prevents elfectixf'ely any separate motion of one log` in relation to the other. Wornout steel cables, of which immense quantities go to waste in every lumber camp, make an excellent reinforcement for the concrete, the manner of placing the reinforcement is not; so very important as the thickness of the slab in itself affords considerable strength. A well reinforced ridge 5 is cast solidly to the inside edge of one of the slabs, and furnishes a buttress which resists successfully any sliding motion of the machinery la on the runners l. The slab 4l which carries the ridge 5 can be utilized as a temporary depository for diverse blocks, tackle and tools.
Having thus described my invention, it will be seen that my objects have been accomplished, and, though I have shown the preferred form of my invention, I reserve to myself the right to make minor changes, providing l. do not violate the spirit and principle of my invention.
l claim:
l. A sled for donkey engines, comprising a pair of runners of rough logs hewn on top to a level surface, a reinforced concrete slab cast in place between the runners at each end of the slab, the upper surface of said slab beinglevel with the top of the runners, 'andbolts extending through the concrete from one side of the runners to the other.
2. A sled for donkey engines, comprising runners of rough logs having a. level surface on top, a concrete slab between the runners at each end thereof, mortises cut into the runners throughout the length of each slab, tenons formed integrally with cach slab by pouring the concrete wet between the runners substantially above the bottom of the runners but level with the upper surface thereof, and bolts arranged in pairs extending through Arunners and slabs, the bolts in each pair being' located one above the other and near the ends of the slabs.
3. A sled for donkey engines, comprising runners` connecting bolts, and concrete slabs poured between said runners and imbedding the bolts, and a reinforced concrete ridge at the inner edge of one of the slabs, said ridge forming a buttress against sliding motion of the superimposed machinery.
Signed by me at Portland, Oregon, this 28rd day of August, 1920.
GEORGE W. IVES.
