SYSTEM FOR LOGGING.

Specification of Letters Patent.

Patented June 27,1916.

Application filed August 12, 1912. Serial No. 714,683.

To all whom it may concern Be it known that I, WALTER C.- KnLso, a citizen of the United States, residing at Bellevue, in the county of Jackson and State of Iowa, have invented certain new and useful Improvements in Systems for Logging, of which the following .is a specification. 7

My invention relates to a system of transportation with special reference-to the transportation of logs from the place where they are cut to the saw mill or other places of shipment; and it consists in so constructing the cars and providing them with a plurality of wheels that the burden will be equalized on both sides of a single track and the weight will not be at any one time at a given point but distributed for considerable distance along the tracle In the following specification when read in connection with the drawings accompanying the same and forming a part hereof, there will be shown and described the manner in which I construct and operate my device to produce the desired results.

Figure 1 is a view in elevation, partly in section illustrating the use of the improved car. Fig. 2 isa side View of the car on the track with hoisting attachment. Fig. 3 is a plan view of the car.

The car forming the subject matter of thepresent invention is designed for use with a single track, which for the purposes of this application may be briefly described as comprising hangers, including rods 12 connected to an appropriate type of sup port (not shown), having their ends beyond the support threaded at 16 to'receive nuts 18. The lower ends of the hanger rods 12 engage in heads 14, of curved arms 15, the lower ends of which arms are formed to provide plain surfaces 20. Girders 8 are secured on said plain surfaces by bolts 22, and the track rails 25 are secured to and sup-. ported on the girders. r

The improved car designed for travel on the track rails, is intended to be so constructed that the load will be equalized on both sides of the track, the weight distributed along the track and adapted to withstand all strainse'specially diagonal and longitudinal strains, and consists 'of the wheels 26 upon a rigid axle 28 which has its bearings on both sides in an axle box 30 at each end of the axle 28. Each axlebox is mounted in proper relation to a supporting block 30 which is rigidly secured between the

bars

32 and 34 by bolts and nuts '35.

The blocks 30 are disposed on oppositesides of the wheel and as will be seen from the drawing form a rigid element of the car frame structure. Each wheel is also connected to each other by said

bars

32 and 34 and between these wheels is located a solid member 37 which is made verystrongand is securely bolted to the bars 32-and 34 by bolts 36. In addition to securing the mem-' ber rigidly, there is provided another bar 33 that is securely bolted to the bar 34 and also running beneath the member and rigidly bolted to the bar 32 thus holding the member with its weight equally distributed upon both sides of the wheels. The car is further adjustablyreinforced by bars 39 that connect the bars 32 and also the bars 34 and are bolted at one end by thebolts 41 and are. adjustably attached at the other end to the bars 32 whereby the bars are more securely:

arms 40 that extend up on the opposite side of the track from the hangerlOand project over the top of the member to which they are securely bolted. These arms are alsoreinforced by the ribs 44,7'and extend down-' wardly and to them are attached the hoisting l device which will be hereinafter described From the above description it will be noted that the car comprises essentially a frame structure including the central member or body which extend forwardly and rearwardly the

bars

32, 33 and 34. These bars in advance and in rear of the body support the spaced parallel blocks referred to,

to which blocks the bars are rigidly connected. This provides arigid frame structure for the full length of the car, the wheels 26 being mounted directly between the "respective end bars of the blocks. It will be seen by this mode of providing two wheels for the track and connecting them together with this rigid member between "and bolting the top and sides to the arms 40 that the" strain will be entirely equalized on both ends of the axis of each wheel, without the crowding of the flange upon the rail and without side twisting 'or racking of the "truck. It will further be seen that as the wheels are quite a distance apart that the strain caused by the weight of the load will not at any one time be upon any one part of the track, but will be distributed along the track and hence the stays that sustain the track may be set at a considerable greater distance apart thereby saving costs in construction.

In order to provide means for loading and unloading with rapidity and economy and still control it with safety to the operator and to the car or platform upon which it is unloaded, there is journaled a shaft 52 in the bearings 53 of the arms 40, upon which shaft is mounted a drum 54. On the same shaft is mounted a gear wheel 55 solid or integral with the drum 54, which gear meshes with the gear wheel 58 mounted on a shaft 60 that is journaled in bearings 59 in said arms 1-0. On the shaft 60 outside of the arms 40 is mounteda chain wheel 62. On the opposite end of said shaft is a brake arrangement which consists of a drum G-l:

' surrounded by a band 65. On the shaft 52 of the arm 72 -is removably attached an.

outside of the extension 50 of the arms 4C0 is a hub 66 adapted to turn freely upon the shaft 52 and held on the shaft in any convenient way. Integral with this hub is a lug 71 to which the band 65 is attached at one end. Also integral with the hub 66is a lever 68 that is curved and terminates at its lower end in an arm 72. To the curved portion of the lever 68 is attached a turnbuckle 67 and to this is attached the other end of the brake band 65. To the lower end operating chain 74 by a hook 75.

The manner of operating this part of my device is substantially as follows: The operator gathers his legs together upon skids or wagons in the usual manner most convenient for the job. He moves the car over where the load has been gathered and brings the chain 59 (one end of which is secured to the drum 54:) around under the load and hooks the other end into the slot 51 in the extension 50 of the arm 40. The other end of the load is attached in the same manner to the duplicate set of arms hanging from another car. Now the load is loosely secured by the chains 59, the operator grasps the chain 63 and rotates the wheel 62 and with it the shaft 60 and this rotates the sprocket wheel and winds it up until the load has become of suflicient height from the ground to be carried along, and the pawl 68 engages the sprocket wheel 70 and holds the'load in the raised condition. The chain 63 is thrown off from the wheel 62 and left for the next load. When the logs are fully loadedhe attaches the power and the cars are hauled along the track to their destination. lVhen the load reaches its destination, the operator attaches' a chain 7 to the lower end of the of the turnbuckle 67.

It will be observed that by this system of logging there will be many advantages in the Way of convenience and in cost both in construction and operation. It will be noted that the car is adapted to direct the pressure of the load to the center of the track without strain from either side and the pressure of the load distributed for some distance along the track and that the means for loading and unloading being simple, so that one operator can attend to it with ease and safety, it will be seen that if operated so as to form a continuous or nearly continuous procession of the loads, at a moderate speed of travel, its capacity will be enormous, and that therefore the cost of transportation and operation will be reduced to a minimum, and the system adapted to all kinds of logging and for logging in substantially all kinds of forests and in their varied situations.

No claim is made herein to the loading means such being expressly reserved for further applications;

It will also be observed that the details of construction may be widely varied without departing from the spirit and the intention of my system.

Having now described my invention what I claim and desire to secure by Letters Pat- 'ent is- 1. A car adapted for use with logging systems including atrack, said car comprising a body, supporting strips secured to the top and bottom of the body and projected in advance and in rear of the body, and a wheel supported wholly by the strips in advance of and in rear of the body, said wheels being arranged in alinement with the longitudinal median line of the body.
