EXTENSION-TOP FOR CAR-BODIES.

SPECIFICATION formingpart of Letters Patent No. 720,923, dated February 17, 1903.

Serial No. 53,025. (No model.)

Be it known that I, FRANK S. INcoLnsBY, a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Extension-Tops for Oar-Bodies, of which the following is a full, clear, and exact descrip'tion, reference being had to the accompanying drawings.

The ultimate object of this invention is to provide means enabling the maximum loading of car-bodies, which term is used herein as including railway-cars or wagons.

In handling loads where the material is relatively light compared to its bulk an ordinary car-body may have its capacity increased by extending its sides upward. I provide such upward extension in a formivhich is readily removable, as well as simple and cheap in construction and efficient in service, and, moreover, is divided into sections, so as to facilitate shoveling into or out of the car, as desired.

The invention consists of the embodiment of these features, as hereinafter shown'and described, the combination of parts set out in the claims clearly summarizing the invention.

In the drawings, Figure 1 is a side eleva-' tion of a car-body having my upward extension, the rest of the body and the runninggear being shown diagrammatically. Fig. 2 is a plan of such car. Fig. 3 is a transverse section thereof. Fig. 4 is a perspective View of one of the brackets for-holding the side boards of the upward extension. Fig. 5 is a vertical section of the end-board extension. Figs. 6, 7, and 8 are horizontal sections on the correspondingly-numbered lines of Figs. 3 and 1, showing the brackets respectively at the corners of the extension, at the intermediate points on the end board, and at the sides. Fig. 9 is asection showing the fastening of the chain, being an enlargement of the corresponding portion of Fig. 3. Fig. 10 is a face view of the chain-fastening.

Referring to the parts by letters, A represents the body of the car, which has at its upper edges the side beams a and the end beams a. These beams carry the upward extension composed of side boards B, end boards 0, and suitable brackets for holding them in place, the term board being used herein simply with reference to the function and including any material, whether wood, metal, or other substance.

Secured to the beams (t and extending upward are brackets D, preferably of the form shown in Fig. 4, whose essential characteristie is th'atthere are presented a pair of grooves (Z, facing in opposite directions and preferably inclined outward. The bracket shown may-be a malleable casting adapted to rest on the upper edge of the beam a and having lips 61 and (Z taking onto the inner and outer sides of that beam, the bracket being held in place by bolts passing through these lips. Thus the portion of the bracket which cooperates with the side boards B is of substantially an I-beam cross-section, and in the two grooves thus provided the ends of the boards B take, as shown clearly in Fig. 8. The side boards may be secured in place by pins passing through holes therein and alined holes (1 in the flanges of the I-beam section.

The above-described construction allows not only the use of short side boards which may be conveniently stored when not in use and conveniently handled, but it also provides for'theseparate removal of any part of the extension, which is of great convenience in shoveling into the car or shoveling out of it. For example, if the car be unloaded by hand as soon as any portion of the load has been lowered to the level of the beam or the side board 13 at that portion may be removed, so that the shoveler will not have to lift the load so high in removing the rest of it. Likewise in loading the car it is desirable not to have to lift the load higher than the beam at until necessary. The end boards 0 are also adapted to be conveniently removed from their operative position. In use they are rigidly carried by theend beam ct of the car; but I allow for their convenient removal from operative position preferably 'by having a hinge in the brackets which hold them,whereby they may be turned down out of the way. This is clearly illustrated in. Fig. 5. There the end board 0 is held by the bracket consisting of two members E and E, pivoted together at e. In use these members are normally locked by the bolt 6, passing through overlapping ears carried at the forward edge of the two parts of the bracket.

When desired, however, the end board may be turned back to the position shown in dotted lines in Fig. 5 by the removal of the pin e. It is to be'understood that this compound bracket E E might be permanently rigid and the end board removed from it by the removal of the pins or bolts e In either event the brackets may be made of malleable castings suitably ribbed, as shown in Figs. 5 and 7, and having lips e and 6 taking onto the inner and outer side of the end beamo and. there secured by suitable bolts. At the corners of the end board I provide brackets of peculiar shape, which serve both to protect the end board and to receive the ends of the side boards. These brackets are shown in section in Fig. 6 and designated F. They are secured to the end boards by suitable bolts, as f. They have flangesf' taking over the ends of the end board, and to the ends of the side board they present the channel-shaped groovef wherefore these extreme side boards are held in substantially the same manner as the'intermediate side boards.

When a caris loaded to its maximum height, the load obtains an increased leverage on the car sides, and there is thus a considerable outward pressure on the sides, and in order to prevent this from outwardly bulging the sides I provide one or more cross-ties in the form of chains G, extending across the car between the beams 01. In order, however, that these chains may be conveniently removed when not required and yet their fastening always remain ready for use, I provide the following mechanism for holding them: At either or both ends the chain is secured to the threaded eyebolt g. This eyebolt passes through the beam (1 and takes into a nut H of peculiar construction. This nut hasa threaded opening to receive the eyebolt g and has a rigid annular flange or collar 71, which rests against a washer J on the side of the car and is rotatively held thereto by the two clampingplates J, which are dished or offset outward to receive the collar h and have an opening into the recess thus provided which the hub of the nut I-I occupies. These clamping-plates meet on the diametric plane and are held to the side of the car by suitable screw-bolts They thus allow the convenient installation or removal of the nut H, while holding it on the car side as desired, whether or not the chain is used, and allowing its convenient rotation to tighten up the chain. A handle It projects from the nut, whereby it may be rotated by hand.

I claim- 1. The combination of a car-body, an upward extension therefor which has an end board hinged thereto but adapted to be held rigid with the end of the car, and side boards, the end board carrying at its ends brackets presenting a groove to the side boards whereby the side boards are held by the end board but do not prevent the end board being turned down on its hinge, substantially as described. 2. The combination with a car-body having a top beam, a composite bracket one member of which is adaptedto be secured to said beam, the other member of which is pivoted to the first member and presents an upwardly-extending arm, an extension-board secured to said arm, said two members having, in addition to their hinge -joint, ears adapted to overlap and having recesses adapted to aline, and a bolt or pin adapted to occupy such alined recesses, substantially as described.

3. The combination of a car-body, a composite bracket adapted to be carried by a I car, of a bracket for hinging and locking them 9 together, said bracket consisting of two members each having a pair of ears, the ears of one member cooperating with those of the other, and two pins, one pin passing through one set of cooperating ears and forming a hinge-pintle, and the other pin being adapted to removably pass through the other ears and form a lock, substantially as described. In testimony whereof I hereunto affix my signature in the presence of two witnesses.
