To all whom t may concern.'

Be it known that l, ALBIN OLssoN, a citizen of the United States, residing at Renton, in the county of King and State of Washington, have invented a new and useful Log- Car, of which the following is a specification.

This invention relates to improvements in log cars and more particularly to a log car of the class known as telescoping cars.

An object of the present invention is to provide a longitudinally extensible and centractible car with means secured thereto whereby an air brake of the ordinary type may be installed upon the car.

A further object of the invention is to provide a longitudinally extensible and conti'actible car with an air brake of the crdinary type secured thereto and adjustable means whereby the air brake is adapted to operably engage the trucks regardless of the distance apart of the same.

With the foregoing and other objects in View which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

ln the drawings accompanying this specification and forming a part thereof, the preferable form of my invention is illustrated,' in which Figure 1 is a side view in elevation of my improved car. Fig. 2 is a bottom plan view thereof with the trucks removed. Fig. 8 is a detail view of the main beam or center sill of the car. Fig. 4 is a detail View in cross section showing the interlocking main beams.

Referring to the drawings in which similar reference numerals designate correspond- Ving parts throughout the several views, 1 are Speccaton of Letters Patent.

Serial No. 769,737.

In order that the car trucks and holsters supported thereby may be positioned at varying distances apart in order to accommodate logs of diferent lengths, the telescoping or interlocking main beams 5 and 6 are provided, a cross sectional view of which is illustrated in Fig. 3 of the drawings. rlhe main beams may be interlocked as shown in Fig. 4, in which the upper beam 6 is provided with downwardly extending tongues interlocking with upstanding tongues of the beam 5. rEhe main beams or center sills 5 and 6 are rigidly secured to the holsters 4 and are adapted to hold the same in spaced relation, it being noted that the said beams extend beyond the bolsters and are provided at their outer extremities with suitable car coupling members 7. lThe main beams 5 and 6 are preferably formed of metal and are provided with a number of slots or apertures 8 extending therethrough and which apertures are adapted to receive suitable holding bolts or pins 9 therein, there being suitable cotter pins 10 or other equivalent means secured to the outer extremities of the bolts to prevent the accidental displacement thereof.

In order that both of the trucks may be provided with automatic brakes operated from a common brake cylinder, mechanism as illustrated in Fig. 2 is employed and this mechanism comprises an air brake cylinder 11 which is operably connected to the floating lever 12 to one extremity of which is secured the reach rod 13 which extends to the forward truck and is adapted to operatively engage the brake rigging positioned thereon. A suitable hand brake operating mechanism 14 is pivotally secured to the remote end of said floating lever.

Pivotally secured to the end of the center beam 6 which supports the cylinder 11 is a transverse lever 15 the one extremity of which is forked as at 16 and is adapted to engage one of a plurality of apertures 17 f floating lever 12 with the fulcrumed lever tracted the pin 21 which extends through the forked portion of the fulcrumed lever 15 and engages one of the apertures 17 is withdrawn, which allows the reach rod 18v to take up a new position with respect to the lever 15 after which the pin 21 is reinserted in place and the brakes of the two trucksl will then be operatively connected to the brake operating mechanism.

Rigidly secured to the center beam 5 is the air pipe 22, the same being provided with a number of flexible hose couplings 23 positioned at various intervals therealong and which flexible hose couplings are adapted to engage a single hose coupling 24 which is secured to the air pipe 25 positioned upon and secured to the main beam 6. Each of the hose couplings 23 are provided with suitable shut-off valves 26 so that when a particular hose coupling is not in use, it may be closed to prevent the escapement Vof air therefrom. The iiexible hose couplings are of the type such as are used at the extremities of the car as shown at 27.

From the foregoing it will be apparent that 1 have provided a car which is longitudinally extensible and contractible and at the same time have provided an air brake operating mechanism secured thereto and which mechanism is adapted to operate the brakes of the forward and rear trucks regardless the distance the same are located apart. The bolsters of the cars are used to directly support the logs or other material of considerable length and limited cross section and due to the construction above outlined, the car will be comparatively light in weight which is of importance in the mountainous logging districts where the empty cars are drawn back to receive a new consignment of logs thereon. Furthermore the conditions met in this service require that substantial brakes be provided which renders it almost absolutely necessary that air brakes be used. By the arrangement of parts as 1 have outlined, the single and ordinary Vair brake unit may be secured to each of the cars and is adapted to adjustably and operatively engage the brake rigging provided upon each of the trucks. Furthermore the providing of a number of hose couplings at various intervals along the divided air pipe which extends along the car allows the said pipe to also take up the differences in length between the two trucks.

The service for which the cars are to be used makes it necessary that the distance between the two trucks of each and every car may be adjusted and in the construction hereinbefore described this is readily taken cured to the said trucks, and air brake mechanism rigidly secured tol one of the said beams and adapted to adjustably and operatively engage the said truck brake rigging.

2. A longitudinally extensible and contractible log car comprising trucks with brake rigging thereon and bolsters pivotally secured thereto, main beams rigidly secured to said bolsters and insertible one within the other, said beams provided with transverse apertures extending therethrough adapted to aline and receive holding means therein, said holding means adapted to hold said beams in` fixed relation, andan air brake operating mechanism rigidly secured to one of the said main beams and operatively and adjustably engaging the truck brake rigging. Y f

3. A log car comprising trucks with brake rigging secured thereto, bolsters pivotally secured to the said trucks, a main beam rigidly secured to one of the said bolsters and provided with a plurality of apertures extending transversely therethrough, a hollow main beam rigidly secured to the other of said bolsters and provided with a plurality of apertures extending transversely therethrough and alining with the apertures in the first mentioned main beam,'said main beams insertible one within the other, means insertible` into the alined beam apertures adapted to hold the same in xed relation, an air brake operating mechanism secured to the said hollow beam and adapted to engage the truck brake rigging there adjacent, and a reach rod operatively connected to the brake rigging of the other truck and provided with a plurality of apertures extending therethrough, said reach rod adjustably engaging the said air brake operating mechanism, air pipes rigidly secured. to thesaid telescoping beams, one of the said air pipes provided with a plurality of hose couplings arranged at intervals therealong, the other of said air pipes provided with a hose coupling adapted to engage the hose couplings of the other air pipe.

4. In a longitudinally extensible and contractible log car, the combination of trucks with brake rigging thereon, bolsters pivotally secured thereto, metallic main beams rigidly secured to said bolsters and insertible one within the other, an air brake cylinder rigidly secured to one of the main beams and operatively engaging'the brake rigging of the adjacent truck, adjustable means en- LGV/41,812 v gaging the brake rigging of the other truck and adjustably engaging the said other truck operating mechanism, air pipes rigidly secured to the said main beams, one of said air pipes provided With hose couplings arranged at intervals therealong, a single hose coupling secured to the other of said air pipes and adapted to engage one of the said plurality of hose couplings of the other of the air pipes, and means for holding the said 10 beams in fixed adjusted relation.

In testimony that I claim the foregoing as my own, I have hereto afliXed my signature in the presence of tWo Witnesses.
