BLOCK RETAINER PAN FOR TANKCARS.

Application filed July 22,

My invention consists in new and useful improvements in body bolster tank slabbing retainer pans for tank cars, and has for its object to provide a device for permanently holding the body bolster tank slabbing in its place without the use of screws,-bolts, angles, corrugations, or the like, and without altering the width of the slabbing. a

I Another object of my invention is to provide an inexpensive and more expedient method for therenewal or adjustment of the body bolster tank slabbingblockson tank cars.

A still further object of my invention is to provide a retainer pan, simple in construction and application, and one which may be manufactured at a considerably low cost.

\Vith the above and other objects in view which will appear as the description proceeds, my invention consists in the novel features herein set forth, illustrated in the accompanying drawings, and more particu larly pointed out in the appended claims.

Referring to the drawings in whichsnumerals of like character designate similar parts throughout the several views,

Fig. 1 is an end view showing two of my improved retainer pans in place on a tank car,

Fig. 2 is an enlarged view similar to Fig. 1, showing the slabbing block in place in the pan,

Fig. 3 is a longitudinal sectional view of the pan, showing the manner in which the slabbing block is held in position,

Fig. 4 is a. perspective view of the retainer pan,

Fig. 5 is a sectional view taken on line 5--5 of Fig. 4.

Fig. 6 is a section taken on line 66 of Fig. 1, and

Fig. 7 is a plan View of a blank, out of which my improved retainer pan is formed In the drawing, 1 designates the retainer pan proper which consists of a sheet of metal preferably sheet iron or steel, out out at its four corners to provide longitudinal flanges 2 and 8, and lateral flanges t and 5, as clearly shown in Fig. 7 of the. drawings. The lateral flanges 4 and 5 are sheared at predetermined points to form spacers 6, 7, 8 and 9, which will be hereinafter referred to more in detail. Adjacent 1927. Serial No. 207,734.

each of said sheared portions 6, 7, 8 and 9, the body of the pan 1 is apertured as at .10. 11, 12 and 13, respectively.

After being cut out and sheared, as before described, the flanges 2 and 3 are bent upwardly at right angles on a line connecting the lateral extremities of the flanges 4 and 5, as clearly shown in Fig. 1. The sheared flanges t and 5 are also bent upwardly at right angles, but on a line drawn substantially through the longitudinal center of said flanges, shown in'dotted lines at in in Fig. 7. The device is now ready to be applied to a tank car. I

14; represents a plurality of body bolsters,

extending transversely of the frame of the car, along each. side thereof, as shown in Fig. 1, each consisting of vertical supporting plates 15, provided along their upper edges with angle irons 16, riveted or otherwise secured thereto, a horizontal supporting plate 17 being secured at its longitudinal extremities to the horizontal arms of said angle'iron 16 as shown in Fig. 3. i

A retainer pan is applied to each of the body bolsters 14 in the following manner. The pan 1 is mounted on the horizontal plate 17 connecting the upright members 15 of the body bolster with the lateral flanges at and 5 adjacent the angle irons 16. Rivets 18 are passed through the apertures 10, 11, 12 and 13 of the pan, and corresponding apertures in the plate 17 and angle irons 16, to retain said pan in place. The spacers 6, 7, 8 and 9, sheared from said lateral flanges, as before stated, are bent inwardly along their inner extremities, over said rivets 18, as clearly shown in Fig. 6, thus forming three separate compartments in the pan 1. The slabbing blocks 19 of conventional form, are then placed in said pan, one in each of said compartments, being held in place and spaced apart from one another by said spacers. The tank 20 is then placed in position in the usual manner, being supported by the slabbing blocks 19.

It will thus be seen that the lateral flanges 4 and 5 will prevent the shifting of the blocks 19 longitudinally, while the longitudinal flanges 2 and 3, and the spacers 6, 7, 8 and 9 will prevent the lateral displacement of said blocks.

It will be further noted, that the application of my improved retainer pan to a tank car, as compared with devices of this character heretofore known, is extremely simple, requiring the minimum number of fastening means, thus providing a durable, simple and inexpensive means for retaining bolster tank slabbing blocks securely in place.

From the foregoing, it is believed that my invention may be clearly understood by those skilled in the art, without further description, it being borne in mind that numerous changes may be made in the details of construction without departing from the spirit of the invention as set out in fllQ'ZIPPEIKlOXl claims. I

lVhat I claim and desire to secure by Letters Patent is:

1. A block retainer pan for tank cars, comprising a sheet of :aiitable metal having flanges extending upwardly therefrom along the longitudinal and lateral edges thereof, a plurality of oppositely disposed spacers within the confines of said flanges, and means for securing said pan to the frame of a tank car.

2. A block retainer pan for tank cars, comprising a sheet of suitable metal having integral flanges extending upwaidly therefrom along the longitudinal and lateral edges thereof, a plurality of spacers formed from at least two oppositely disposed flanges, whereby said pan is adapted to retain in spaced relation a plurality of slabbing blocks. r

3. A block retainer pan for tank cars comprising a sheet of suitable metal having integral flanges extending upwardly therefrom along the longitudinal and lateral edges, thereof, a plurality of oppositely disposed spacers extending upwardly and inwardly within the confines of said flanges, and means for securing the pan to the frame of a tank car.

4:. A block retainer pan for tank cars comprising a sheet of suitable metal having integral flanges extending upwardly therefrom along the longitudinal and lateral edges thereof, a plurality of spacers formed from at least two oppositely disposed flanges, means adjacent said spacers for securing said pan to a tank car, said spacers extending upwardly and inwardly over said securing means.

5. In a tank car, a block retainer pan, comprising a sheet of suit-able metal having upwardly extending side and end walls, a plurality of oppositely disposed spacers adjacent said end walls, a plurality of tank supporting slabbing blocks carried loosely in said pan, said spacers and walls serving to limit the longitudinal and lateral movement of said blocks, and meansfor securing said pan to said tank car.

6. A method of making a block retainer pan for tank cars, which consists in cutting a sheet of suitable metal to form longitudinal and lateral flanges, shearing said lateral flanges at predetermined points, drilling apertures adiacent said sheared portions, bending said flanges upwardly at right angles to said sheet, and bending said sheared portions inwardly along a line within the confines of said flanges, over said apertures. In testimony whereof I affix my signature.
