LOG LOADING AND SKIDDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 757,234, dated April 12, 1904.

Application filed October 23, 1903- To all whom, it may concern:

Be it known that I, MICHAEL SoHMAL'rz, a citizen of the United States, residing at Duluth, in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements in Log Loading and Skidding Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to log loading and skidding machines.

It consists of an engine-bearing car, which Iwill call the locomotive or engine car, and of an exterior or envelop derrick car adapted to move on the same track as the engine-car and when desired to suspend said engine-car above said track.

It also consists of certain other constructions, combinations, and arrangements of parts, as will be hereinafter described and claimed.

In the drawings, Figure 1 is a side elevation of a machine embodying my said invention. Fig. 2 is a front end elevation of the same. Fig. 3 is an enlarged bottom plan view of one of the sills forming part of said invention. Fig. 4 is a still furtherenlarged crosssectional view of .the same. Fig. 5 is a top plan view of said machine omitting the hoisting cables and showing the derrick poles partly broken away, and Fig. 6 is a bottom plan view of said engine-car.

Referring to the drawings, the derrick-car consists, substantially, of a frame comprising transverse sills 1 and 2, brackets 3, mounted, respectively, upon the ends of each of said sills, posts 4 and 5, erected upon each of said brackets, transverse overhead beams 6 and 7 at each end of said frame and secured in any suitable manner at their ends to the contiguous said posts, longitudinal upper beams8 at each side of said frame, extending from the post 5 at one end of said frame to the similar post at the opposite end thereof and secured thereto by any suitablemeans, as by brackets 9, longitudinal lower beams 10 at each side of said frame, ex-

tending from the post 5 at one end of said frame to the similar post at the opposite end Serial No. 178,184. (No model.)

thereof and secured thereto by any suitable means, as by brackets 11, derrick-poles 12,

pivotally connected at their lower ends to the opposite sides of said frame, at one end thereof, and converging and secured together in any suitable manner at their upper ends, as by a cap 13, and a spacing-post 14, erected be tween each of said posts 4 and 5 and of lesser thickness than said posts 4 and 5, whereby vertical guideways are formed between said posts 4 and 5. Said sills are preferably adapted to extend across the rails A and B of a railway-track and are channeled underneath to receive the shaft and wheels 16 of single supporting-trucks. Said sills also have formed thereon near each end hoods 17 to receive the journal-boxes 18 of said trucks. Said trucks are preferably secured in said sills by bolts 19, extending through said sills below the axles, but may be secured in any other suitable manner. Springs 20 are preferably interposed between said boxes and the overhead portions of said hoods, whereby said sills are normally raised clear of said track and supported upon said trucks. When, however, the weight of the engine-car is suspended from the frame of said derrick-car, said boxes recede in said hoods and said wheels recede in said sills and the sills bear directly upon the track-rails. The sills 1 and 2 are also each provided near each of their ends with oppositely-directed angular extensions 21, the upper surfaces of which are inclined from the top of said sill downwardly to said rails, and such inclined surfaces are preferably formed with an offset portion 22 to accommodate the flanges of any wheels passing from said rails over said inclines. Between said clevises 23 are preferably pivotally secured sockets 24, adapted to receive the lower ends of said derrick-poles. Backstays 24 are secured in any suitable manner to the apex of said derrick and extend divergently backward over rollers 25,1:nounted upon the upper part of the rear end of said frame and downwardly to windlasses 26, keyed to-similar transverse shafts 27 journaled in brackets-28, secured to the rear end of said frame. Worm-wheels 29 are also keyed to each of said shafts 27 and are adapted to engage Worms 30, keyed to shafts 31, which are provided with a crankhandle 32 andjournaled in brackets 33, secured to the posts 4 and 5, respectively, at the rear corners of said frame, by means of which windlasses and backstays said derrick is adapted to be adjusted and held at any suitable angle. Mounted in any suitable manner on the transverse overhead beams or either one of them, at the front end of said machines, are antifriction-rollers 34, adapted to support said backstays when the outer end of the derrick is lowered below the horizontal plane of said overhead beams. Suspended from the apex of said derrick in any suitable or well-known manner is a hoisting-sheave 35, adapted to support a hoisting-cable 36. Pivotally secured in any suitable manner to each of said sills or, preferably, as shown, to each of said brackets are dogs or spuds 37, the free ends of which are adapted to drop down at an angle forwardly or rearwardly, as desired, to engage the ties to prevent the forward or rearward movement of said derrick-car along said track. When not in use, said spuds may be swung upward and their free ends lodged in vertical guideways between said cornerposts. It will be observed that said sills, with their inclined extensions, form bridges over the trucks of the derrick-car, which bridgesills have tracks formed upon them over which the engine-car or other cars may pass from the rails A and B. I therefore call said sills bridge-sills. Said frame or derrick-car in most particulars corresponds in construction to the derrick-frame described in Letters Patent of the United States, dated May 12, 1903, No. 7 27 ,849, issued to me for log-loading machine, and I do not now, therefore, claim the same broadly.

The engine-car forming part of my said invention comprises a platform-car 38 of any suitable construction, havinga hoisting, skidconstruction mounted thereon, the elements of said engine used for hoisting and those used for skidding being well known to the art and not necessary to be particularly described herein. The shaft of one of the hoisting-drums of said engine is provided with a clutch 40, slidably keyed thereto and adapted 'in operation to engage a sprocket-wheel 41, loosely journaled on said shaft. Said sprocketwheel is belted by a chain 42 to a sprocketwheel 43, keyedto a shaft 44, journaled in bearings 45, depending from the frame of said car, beneath the platform thereof, which shaft 44 carries two other sprocket-wheels 46 and 47, keyed thereto and belted, respectively, to sprocket-wheels 48 and 49, keyed to the axles of the forward and rearward trucks of said car, whereby said engine is adapted to drive said car along the track. Said driving means is substantially the same as shown in my said Patent No. 727,849. The shaft of another of said drums is provided with a.

clutch 50, slidably keyed thereto and adapted in operation to engage a sprocket-wheel 51, loosely journaled on said shaft and belted by a chain 52 to a sprocket-wheel 53, keyed to a shaft 54, journaled in bearings 55, depending from the frame of said car, beneath the platform thereof. Said shaft 54 also carries two other sprocket-Wheels 56 and 57, keyed thereto and respectively belted to sprocket-wheels 58 and 59, keyed to shafts 60 and 61, respectively, journaled, respectively, in bearings 62 and 63, depending from the frame of said car, beneath the platform thereof. Said shaft 60 also carries a gear-wheel 64, keyed thereto and adapted to engage a gear-wheel 65, keyed to a shaft 66, journaled in bearings 67, depending from the frame of said car, beneath the platform thereof. The shaft 66 also carries two spools 68, keyed thereto. The shaft 61 carries a gear-wheel 69, keyed thereto and adapted to engage a gear-Wheel 7 O, keyed to. a shaft 71, which is journaled in bearings 7 2, depending from the frame of said car, beneath the platform thereof. Said shaft 71 also carries two spools 73, keyed thereto. Secured at one end in any suitable manner to each of said spools are cables or chains 74, extending therefrom upwardly through the platform of said car and in operative position secured at their upper ends in any suitable manner to the overhead portion of said derrick-frame. I preferably provide hooks upon the upper ends of said cables or chains adapted to engage the eyes of depending eyebolts 76, secured to plates 77, seated upon and bolted to said transverse beams 6 and 7. The chains are thus detachable at their upper ends. It will now be readily understood that said enginecar may be easily run from the track over the inclined extensions of either of the sills of said derrick-car and stopped between said sills and that the chains 74 may then be attached to said eyebolts 76 and the engine-car raised into suspension within and from said derrick-car, at which time empty logging-cars may be run through said derrick-car beneath said enginecar. The engine-car may then be lowered and said hoisting-cable 36 secured to one of the drums of said engine and operated to lift logs onto the logging-car in front of said derrick. Said hoisting-cable may remain attached to said drum while said engine-car is within the derrick-car whether the engine-car is raised or lowered. The engine-car may of course be easily disconnected from said derrick-car and run out of the same. Skidding-lines may then be secured to one or more of said drums and operated to draw logs from a distance to the track side, said skidding-lines being led in the usual and well-known manner through guidepulleys or purchase-pulleys secured to stumps of trees or any suitable anchorage. When disconnected from said derrick-car, said engine-car may also be used to push or pull other carsor perform various other railway Services, to aid in which car-couplers 78 of any suitable construction are preferably secured to said engine-car, at each end thereof. In order to keep said engine-car from swaying while in suspension in said derrick-car and to prevent longitudinal movement of said enginecar with respect to said derrick-car, I provide castings 79, secured in any suitable manner to said engine-car, at each corner thereof, upon each of which castings are formed upwardlydirected apertured lugs 80, adapted to receive horizontally-arranged sliding bolts 81, projected therethrough and adapted in operation to loosely engage the guideways formed between the contiguouscorner-posts of said derrick-car. Said bolts are further secured in operative position by pins 81, projected downwardly through said bolts and into or through any suitable portion of said lugs or castings.

When it is desired to disengage said engineciency for various purposes, possesses great advantages over other loading-machines and is especially practical for use on temporary railways and in localities Where extensive repairing facilities are not conveniently at hand and where wholly independent equipment for all the classes of service performable by said construction would be prohibitive. It will also be observed that while loading the center of gravity of said machine is low and the tendency to tip over reduced to a minimum.

Having now described my invention, what I claim, and desire to secure by Letters Patent, 1s-
