TIMBER-POCKET.

SPECIFICATION forming part of Letters Patent No. 607,867, dated July 26, 1898.

- Application me December 10,1897. Serial No. 661,410. (Ne model.)

I a citizen of the United States, residing at the city of St. Louis, State of Missouri, have invented a certain new and useful Improvement in Timber-Pockets, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in

' elevational view of the same.

a lateral wing.

i used as a carline-support.

which Figure l is a view representing a portion of the skeleton framing of a car, showing the application of my improved timber-pocket, said view being taken on line 1 1, Fig. 2, looking in the direction of the arrows. Fig. 2 is a side Fig. 3 is a plan view of my improved timber-pocket. Fig. 4 is a sectional View through the same on line at 4, Fig. 8. Fig. 5 is a side elevational View of the same. Fig. 6 is a bottomplan view showing my improved pocket provided with Fig. 7 isa side elevational view of the same. as seen from the other side. Fig. 9 is a side elevational view of my improved pocket when Fig. 10 is a plan view of the same. Fig. 11 is a plan view of a modified form of pocket. Fig. 12 is an edge View of the same. Fig. 13 is an edge view of the pocket when used as an end-plate support, and Fig. 1a is a plan View of the same.

This invention relates to a new and useful improvement in timber-pockets, the object being to provide a metallic pocket for receiving the end of a timber, whereby the same may be firmly secured in position against an other timber without mortising the latter.

The special features of this invention reside in the novel construction of the pocket,

as will hereinafter be described, and afterward pointed out in the claims.

In the drawings I have shown a portion of the skeleton timbers of a car in connection with which my improved pocket is illustrated; but it will be obvious that there are many other uses to which my pocket could be put without in the least departing from the principle of my invention.

Fig. 8 is a similar view,

In the drawings, A indicates the end plate, 13 the side plate, 0 the end posts, I) the side posts, and E the carlines, all of said parts being common and well kuownin car construction.

F indicates my improved pocket as an entirety, which, as shown in detail in Figs. 3, 4, and 5, comprises a base-plate fand side walls f, f and f. The base-plate f has a hollow boss f and a stud or dowel pin f extending outwardly therefrom, said boss and stud fitting in suitable recesses or holes in one of the timbers when the pocket is applied.

f indicates an-opening in the base-wall for the passage of a truss-rod should one be used and it is desired to have the same countersunk or flush with the side face of the timber whose end is received by the pocket.

The edges of the walls f and f are formed with guideways, in which is received a slide f said slide being tapered, as shown in Fig. 4, and also provided with an opening or hole f for the passage of a wood-screw, by which the slide is secured tothe timber whose end is received by the pocket.

As will be seen by reference to Fig. 4, the inner faces of the grooves in the walls f and f for the slide f are practically parallel with the wall f while the outer faces of said grooves incline toward the base-platef. The object of this is to cause the slide f to move inwardly as it is driven home, so as to tightlycrowd and bind the end of the timber in the pocket to prevent lateral movement of said timber, after which the Wood-screw is introduced to secure the slide to the timber and in position.

f indicates a wing against which the end of a diagonal post may abut, as shown in Figs. 1, 2, 6, 7, and 8.- This wing or lateral plate is also provided with a dowel f as shown, if desired.

If desired, a removable key f may take the place of the wall f2, so that the timber whose end is to be inserted in the pocket may be placed in position from either side.

The use of my improved timber-pocket and its application can be readily understood from the drawings. I will state, however,

that in practice I prefer to bore the timber on which the pocket is to be secured with holes of sufficient size and depth to receive the dowels f f and f When the pocket is, placed in position, lag-screws are inserted through the hollow dowels and firmly secure screw which holds the slide in position and I take out the slide, when the timber may be 1 readily removed.

The key f, used in place of the wall f (see Figs. 11 and 12,) is to enable the timberto be inserted or removedfrorn two sides of the structionof new cars, as it is more convenpocket. This is advantageous in the con ient to insert the timber from the outside, and

- after the car is completed and the sidin gs and the facia in place if it is desired to remove a timber it may be done from, the inside. The key f is really a movable side, sliding in suitable openings in the side walls f and f One end of this key f is provided with a flange or bent portion which is approximately at right angles to the key proper and is designed to act as a stop for the inward move ment of the key, said bent portion being provided with a suitable hole so positioned as to register with a correspondinghole in the side f these holes being designed to receive a suitable screw to secure said key in its correct position'to the timber.

I am: aware that many minor changes in the construction, arrangement, and combination of the several parts of my device can be made and substituted for those herein shown and described withoutin the least departing from the nature and principle of my invention.

' Having thus described my invention, what I claim,-and desire to secure by Letters Patent, is-

l l. The herein-described timber-pocket com- I prising a base-plate provided with means of attachment to a timber, side walls formed with seats for a slide,the outer faces of which seats are inclined to force the slide inwardly as it is introduced to crowd or bind the end of the timber in the pocket, anda removable slide, substantially as described.

'2. 'Theherein-described timber-pocket comprising a base-plate, dowels rising therefrom, side walls f and f a slide f and a key or slide f, substantially as described. I

In testimony whereof I hereunto affix my signature, in the presence of two witnesses,

this 30th day of November, 1897.
