SETTS 4 FOLDING 7 Application filed May 27,

This invention relates to a folding support and particularly to a type of support that is adapted to support a casket.

The object of the invention is to provide a support of light, strong and simple construci folded to its open position, thereafter making it impossible for the support to collapse without first actuating the locking means to unlock the top members.

Another object of the invention is to provide diagonally positioned bracing means for the lower portion of the support, said bracing means being actuated automatically to break the bracing effect when the adjacent abutting portions of the top members are moved upwardly in folding the support.

The invention consists in a support as set forth in the following specification and particularly as pointed out in the claims thereof.

Referring to the drawings:

Fig. 1 represents a front elevation of a support embodying my invention, said support being located in its open position.

Fig. 2 is a side elevation of the support.

Fig. 3 is a front elevation illustrating the 7 support in its collapsed or folded position.

Fig. 4 is a detail sectional view illustrating the manner in which the operating rod for the diagonal braces is connected to one of the top members.

Fig. 5 is a detail sectional elevation illusgrating the locking means for the top memers.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, 6 represents the side frames of the support, each of said frames being preferably constructed in a single piece of cast aluminum. Pivotally attached to each side frame 6 at the top thereof is a top member 7 also constructed in a single piece BOSTON, MASSACHUSETTS, A CORPORATION OF MASSACHU- SUPPORT 1930. Serial No. 455,993.

of cast aluminum. The top members 7 have ears 8 formed integral therewith, which co-- operate with ears 9'formed integral with the frames 6 and said earsare connectedtogether by meansof a pivotal pin 10. The cars 8 and 9 are so positioned upon the top members 7 and side frames 6 respectively that when the top members are located in their openposition that they will rest in a horizontal position with their lower edges supported upon the top edge of the frame 6.:

The top members 7 are pivotallyv attached one to another at the center of the support by means of pivotal pins 11 which project through co-operating ears 12 which are provided upon the top members. The side frames 6 are strongly braced adjacent to the bottom thereof by a plurality of braces 13, of which there are four in number, positioned diagonally. One end of each brace 13 is pivotally attached at 14 to a corner portion of r the frame 6 and all of the'braces arepivotally attached together at 15, the pivotal point be ing located in a transverse plane whichpasse'sf through the center of the support and which also includes the pivots 11 of the top imem bers 7. The braces 13 are operatively con-- nected to one of the top members 7 by means of a rod 16, the lower end of which is co axially pivoted at 15 to the inner ends of the braces 13. At its upper endthe rod 16 is pivotally attached at 17 to an ear 18 which is formed integral with one of the top members 7 and the axis of the pivot 17 is co-axial with the axes of the pivots 11 of the top members 7. d

The mechanism for automatically locking the top members 7 in their open position thereby holding the entire supportin its ing the latch 22 to the catch 19, and a fiat spring 25 which is attached to one of the ears 12 engages the latch 22 in a manner to normally hold the notched portion 24 of the latch 22 in engagement with the notched finger ofthecatch-lQ. a

The supportsof this invention are used in pairs, each support being insertedbeneath an end portion of a casket and both of these supports are held spacedapart by any suitable form of spacing means, and when the supports are located in their open position, the top members 7 are locked securely'together by the locking mechanism and when said top members are so locked the lower pbrtionsf ofthe side :frames 6: 211'6 effectively braceId'and it is impossible to break the pivotalnonnection15 by means of which the brace, members13 are joined; together.
