LOGGING-CAR BUNK AND STAKE.

Specification of Letters Patent.

Patented Mar. 4, 1913.

Application filed February 12. 1912. Serial No. 677.008.

To all whom it may concern Be it known that I, CLAYTON T. Earn, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful lniprovements in Logging-Oar Bunks and Stakes; and I do declare the following to be a full, clear, and exact description of the invention, such as will onable others skilled in the art to which it appertains to make and use the same.

This invention relates to railway rolling stock, and more especially to freight cars adapted for conveying logs; and the object of the same is. to produce improved means for holdin a load of logs, poles, or lumber and for rdleasing the same from that side workmen to be injured by the falling of the load so released and dropped. This and other objects are carried out by the construction hereinafter morefully described and claimed, and as shown in the drawings wherein Figure 1- is a side elevation of the sill of the car truck, giving an end view of two of m improved bunks and an elevation of two o my improved stakes as used in connection therewith. 2 is a side elevation of one of my improved bunks with the nearer I- beam removed and the top plate in section, and both stakes engaged by the chock of the device showing the carriage as having been moved to disengage the chock blocr from the stake and the latter in the act of with the stake omitted, a considerable' por'- tion of the view being in section on a line just beneath the upper flanges of the can ria es. Fig. 5 is a View similar to the right on of Fig. 2 with the stake omitted, the

ward along the Lbeams'th'an in Fig. 3. Figs. 6 and 7 are enlarged details showing the latching mechanism with the cam in two different positions as will be referred to hereinafter. Fig. 8 is a perspective detail of the latch. Fig. 9 a perspective detail e l? one of the stakes and of so much of the other parts as it engages when it is locked in substantially upright position.

in the drawings the numeral 1 designates part of the platform of a car or other Vehicle such as is "used for transporting logs,

poles, lumber and possibly other freight of similar shape, although this invention is espec ally applicable to articles wlnch are cylindrical 1n contour and rather long and which by their shape are therefore likely to roll off the vehicle. If the load should consist, for instance, of three rather large logs as shown in dotted lines in Fig. 2, it may be easily held on the vehicle by the use of chock blocks properly disposed, and as an' 5 element of safety it may be additionally held by means of two stakes although the latter are ordinarily used for holding a, larger load of articles of rather smaller size. \Vhen it is desired to dump the larger logs, it is usually necessary only to remove the chock blocks or stakes or both, and either permit the logs to roll olf or to stop them by means of a crow bar. Once started,

the load goes with a rush, and operators at that side of the car have not time to escape and therefore are frequently injured or killed. One object of the present invention is to render it impossible for an operator to release the chock block or stake on that 30 side of the car nearest to him, and therefore no matter how careless or forgetful he may be it is impossible for him to unload a log toward himself. This object would be carried out by disposing one of my improved g5 bunks at the mid-length of a rather long platform car to engage the center of long logs loaded thereon, leaving their extremities to be chocked by other ordinary means;

but when a platform car is provided with this device,'there'are usually two of them put in place as indicated in Fig. 1. although as they are duplicates of each other I need I describe but one.

Upon the sills of the platform 1 bed 9- these beams 4 may also be connected by transverse straps or plates (3 passing b0- neath them and secured to their lower flanges as shown in Figs. 2 and 4: and they 1 are further held in spaced relation-to each other by means of a plate 7 extending over their upper flanges and bolted thereto as. at 8, this plate being of some considerable length as shown in Fig. 2 and having up standing flanges 9 along its edges so nsto slightly indent the log or logs luul thereon At 1 suitable points throughout their length as indicated "in dotted lines and.. 1')ie\Tent the same'from moving longitudinally upon the car body. :The parallelspacedl beams 4 are thus rigidly mountedv across the sills of-a car oro ther vehicle, their upper flanges, and the flanges 9 of the plates 7'-const1tute supports for the load, and thespace between the beams constitutes a runway 6r- '-track for the carriage next to be described;

Thererare two such carriages fpr each run? way, one disposed at each end of the latter,

- and each carriage is made up of a pair of through saidweb and headed up as at 18 I 4 toform a pivot. The arm l beams 10 all. dimensions of "which are smaller than those ofthe I-beams 4,- the webs of said beams 10' being spaced by v .blocks' 11 through which passfastening "bolts '12 as best seen in-Fig.- 4. Outside the web of one beam (for instance,-the right-.- T hand one of the pair) is disposedan lL-" shaped plate 13 having a rack bar 14 on its outwardly extending flange, and; engaging this rack baris the lip 15 atone extremity of a-U-shaped latch l6-whose body li'es outside the web of. the adjacent'beam 4 and whose opposite extremity 17 is inturned lip 15 moves in a slot cut o-nan are around the pivotal .end '17 of this latch} through the web ofthe beam 4 as best seen 1 in Figs. 6 and 7,, and thelipy 15 depends from the 'innerend of the arm 19 and .is

adapted to engage the notches in the rack bar 14 in a manner which will. be. clear. The means foractuati'ng thisulatch consist of 'a push bar -or rod20 slidably mounted beam 4 is attached behind the bolts .8 above described and behind the screws orbolts 5 by which the to one of the plates 2, and the handle 21 of the rod stands at the remote end of the track or runway from the position occupied by the carriage being described, for a purpose which will appear below.-----The.inner end of the rod formed into a 23 underlying the movable arm 19 of the latch and whose bill forms a guard 24 overlying-said arm as best seen-in'Figs. 6 and 7. From this construction it is. obvious that when the rod is manipulated by its handle 21 the cam 23 may be forced under said arm 19 to raise the latch to the position shown in Fig. 7 so that its lip 15 disengages the rack bar 14 but when the rod is moved in the opposite dlrection'the arm rides down the cam and the guard 24 moves .over the arm so that the lip .reengages the rack bar 14 and the guard prevents it'from accidental disengagement therewith. As seen the carriage ateach end of the track or runwe is locked and unlocked'by a latch control ed by a rod Whose handle stands at the ,pposi te side of the car, the purpose of which will be explained below. a t the outer extremities 0 both I-beams 19 carrying the,

hook whose shank has a cam ins-5.15

all their inner flanges are cut-away 21S:- shown at 30, and-between their webs onv a bolt 31 ,is pivoted a check block 32 whose thickness is such. that it may move freely be'tweenthe inner edfges 'ofthe flanges of the Lbea'ms 4. Vihen idle this block hangs as-"seen in Fig.3, and through its body I passesa'pi'n 33 whose extremities rest on the inner'flanges of the mainbeam-s' twhen the chock" block is. raised asrseen in Fig. 2

and may even slide inward thereon to a considerable extent when the carriage must be adjusted lnward as, seen in Fig. 5 to bring the chock block under a somewhatsmaller I load. A. pin. 34 is properlyfdisposed :prevent this block from shown in Figs. 2 and5,

pivotal bolt, 31 it follows riage is moved outward and :the'pin '33 passes oft the extremities of the fiangeseof the main beams 4 the check block Will -fall,

and the pin will-passaround the 'ends of ,said beams to the positionshown in Fig; 3. Thedevice as. thus far constructed is quite bunk in, such manner off of the same. posed as indicatedby the dotted linesin Fig. '2, the carriages being moved inward sufiiciently to cause thecliock blocks to rest beneath the outermost logs in a manner which will beclear. VV'hennow it is deonefiside of the car asshme the position as explained above; be unlatched' to permitthe freeing of this chock block by an operator who must of must be permitted to shown in Fg'J-3; and,

the; carriage can only I through the-Webs -of thetwo-beams 'lO-to. a

rising higher than and as its; center of gravity "is therefore always outside offYi/tsha whe l'the. carp 'useful for supportingaload of logs or rather,- large cylindrical. articles upon the" that they cannot .roll- They are obviously dis-" j necessity stand at the opposite side of the car and is therefore-free from. danger injury by the falling logs.

In' connection with above, described I use a stake of peculiar construction in order that the improvementsit will -..co5perate with the chock block and the mechanism for I of sufficient width to 'span theweb of the two .-main'beams' 4, it is provided with a cross bar 45 adapted to rest against the-ends of said Webs, beneath this bar" the inner edges of the sides of said loop restagainst the outer flanges of saidbeams, and the loo sired to dump the load the chock-blockatv vide each loop with a deflected cross bar notches as best seen in Fig. 9, and it' the notches at? are employed their engagement with the extremities of the outer flanges of the main beams 4 will prevent the stake from moving upward or downward or inward at this point, and the fact that the body of the loop surrounds the webs of said main beams will preventit from moving transversely thereon. In order now to prevent the lower end of the stake from being moved outward, I provide the side bars of said loop with downwardly projecting hooks 49 engaging eyes" 50 in the outer lower flanges of said main'beams; and as the stake cannot rise for the reason just described, the hooks cannot disengage the eyes. Finally. in order toprevent the upper ends of the hooks from moving outward, I'pro which is in effect an eye-5i properly disposed to be engaged by a hook 52 in the chock block 32 when the latter is elevated as seen in Fig.2.- Thus it will be seen that a stake of this specific construction is particularly applicable to a chock block of the construction described, especially when the latter is controlled by a carriage which is locked and unlocked as has been set forth.

Assuming that the stake is locked irrnpright position as'shown at the leftof 2. When it is desired to release the load whether the same be logs as indicated or smaller articles, an operator (who of neces sity must be at the opposite side of the car) pushes inward on the handle 22 whereby the cam 23 is forced beneath the arm 19 of the latch 16 and the lip 15 thereof'is raised out engage each other, and the hooks 49 are disengaged from the eyes 50 and the stake is disconnected from the main beam just at the time that the chock block commences to swing downward around its pivot 31. As it falls to the position shown in Fig. 3 its hook disengages the eye 51 completely, and the entire stake falls out of the way and is retained merely by the chain 4-1. Thus the chock block and stake are simulman who must have actuated the latch from This tancously and automatically removed from beneath the log near that end ot' the bunk, and the log rolls oil" on the ground without the possibility that it may injure the workthe opposite side of the car. In this position of parts the chock block is entirely "out of the way and the stake either hangs pendent by thechain 4* or is entirely removed, and the result is that the car may be used for other purposes.

When now it is desired to again load a car provided with this invention, the parts are set up to the position shown in Fig. 2 and the load must be passed over the upper ends of the stakes. The latter, however, are locked against movement in all directions in the manner described above, and if in the act of loading some of the load should strike the stakes they will not be dislodged from their position. If it should. so happen that the load is smallerthan the width of the car or the length of the main beams 4, the stakes will be disengaged from the hooks 42 and tho carriages moved inward as shown in Fig. 5'so that the chock blocks alone support the load in a manner which will be clear.

I do not wish to be confined to the specific details of construction, as it is to be understood that this specification is merely descriptive of one embodiment of my idea and that changes in detail may be made wit-hm the spiritof the invention.
