hearses-of'the type employing power driven caske't' carrying tables, which are-movable to carrying position within 'the' hearse orto delivery-or receiving positions, through a hearse'door.

' In the use of such apparatus the power means ,'ior,moving the table is connected thereto ina more or less permanent manner, so that in the event of power failure the table is renderedinoperative'and requires a liitingof' a casket into or out of the hearse by'hand'to the inconvenience, embarrassment and annoyance of the attendants. The primary object of the present invention is the provision ofa simple and efficient releasable connection between the power means and table of a hearse oi the character described, which means is manuallyxoperable in a simple and easy manner toiquickly release the table from the power means in the event of power"f ailur'e. .or otherwise, so that the'table may-then be freely moved by hand to loading or carrying position.

A furtherobject' of thein'vention is the provision of such arelease means which, in 'addi:

v Further objects and advantages of the inven I tlon willbe-apparent from the following detailed description and from the accompanying drawings showing one embodiment thereof, in which- Figure ljis a fragmentary planview of a hearse with: a part of the body'in' horizontalsection and with the casket-carrying table shown in full lines in! casket-carrying position and in dotted lines in casket-delivering 'or receiving position; Fig. .2

Referring to the drawings, l designates a hearse having a casket-carrying. table 2 mounted and guided formovements therein, whereby it may be disposed in carrying positionwithin the hearse,

as shown in fulllines in Fig 1, or moved therefrom, to; loadingor delivery position asshownby dotted 1939, Serial No. 290,618,"

(01. ram-e5) 7 lines in Fig. 1; as well understood in the art'.

The table is mounted slightly above the hearse" 41001 3 for freesliding movements on the, customary anti-friction rollers or supports. The guiding ofithetablemay be effected by members projectingcdownward therefrom and working. in v guide slotsprovided in the floor, as is common in the art. In the present instance (Fig. 2), 5

designates a guide slot extending lengthwise in the hearsefioor centrally of its sides. This slot is provided at the upper edges of its: side walls withinturned guide flanges 6.

' The power means for the table is shown in the I catch: means comprising the invention, a verside of the flanges 6 at the respective sides of the slot. -In the present instance, the sleeve II rotatably projects through a central opening in;

the truck ltandis flanged beneath such truck, as shown at I5. I

A catch-pin head It is mounted for reciprocatory movements in the lower end of'the sleeve ll and'has a tapered lower end for releasable engagement within a slot or recess I! in the top of a catch block Iii attached to the power member Hi. This bIOCkiS provided with rollers 19' for traveling in a channel guide 2% extending lengthwise beneath the guide slot Sand secured in some suitable manner to the'underside of the floor 3. 'The' top surface ofthe .catch block l8 at front'and rear of the recess. I! is preferably beveled downwardly and outwardly from the top of the recess wall's'forfacilitating engagement of the catch-pin with the block recess when the block is moved under the pin from either direction of movement.

The catch-pin I6 is normally held projected,

coiled expansion spring 22 mounted within the sleeve H between the head and a washer 23 shouldered in the sleeve. The bore of the sleeve H is reduced above the washer 23 and receives a plunger 24 which has a stem 25 projecting downward from its lower end through the washer 23 and in fixed engagement with the catch-head l6, so that the head and plunger move together. A slot 26 extends diametrically through the plunger 24 and registers at its ends with slots 21 in the front and rear sides of the sleeve ll within the table 2.

The table 2 is recessed at its under side to receive a sleeve block 30 through which the sleeve II is fitted, such block being fixedly secured to the table, as by welding if the table is of metal or its recess is bounded by metal, or in any other suitable manner. The sleeve block 30 is slotted at opposite sides in registry with the sleeve slots 21 and has the walls of its slots extending lengthwise of the table and away from the sleeve II by extensions 3! on the block.

A stud cam 35 is guided for longitudinal reciprocatory movements by the sleeve block 30 between the extensions 3i thereof and extends through the slots 2'! of the sleeve H and also the slot 26 in the plunger 24.v The cam 35 has a narrow neck portion 36 which, when within the plunger slot, permits the catch pin Iii to be lowered into engaging position with the catch block I8. A cam surface or incline 3'! extends outward in one direction from the neck 36 and is adapted when drawn into the plunger 25 to cause a raising of the plunger and consequent raising of the catch pin l6 from catch block engaging position, as shown in Fig. 4. The cam 35 has a stop lug 38 at one end for engagement with the sleeve block 30, as shown in Fig. 4, to limit the catch pin releasing movement of the cam, and at its other end is provided with a shouldered part 39 for engagement with either the sleeve l I or the side of the plunger 24 to limitthe movement of the cam in the opposite direction. Extending in the present instance from the neck end of the cam is a control rod 40, which projects lengthwise of the table 2 through an opening provided therein for the purpose, and extends without the forward end of the'table. The rod 49 at its forward end is provided with a handle 4|.

When the parts of the releasable catch means have been assembled with the sleeve I I mounted in the sleeve block 30 and the truck l3 disposed within the floor slot 5, the nut I2 is turned down against the sleeve block 30 to cause the truck rollers M to exert an upward pressure against the guide flanges E5 and to hold the table 2 down on its supporting floor rollers. When the parts have been so assembled in connection with the table and floor, the catch pin head i5 is released from or permitted to have catch engagement with the catch block H8, at the will of the operator, by movements of the rod 40 and its cam 35, as is apparent. The outer end 4! of the rod 40 is in convenient reach of the operator, so it may be easily controlled. When the catch has been released the table 2 may be freely moved by hand relative to the power means the same as when the hearse is not equipped with power operating means for the table. It will be understood that the table 2 is held in casket-carrying position within the hearse in any suitable manner.

I wish it understood that my invention is not limited to any specific construction, arrangement or form of the parts, as it is capable of numerous modifications and changes without departing from the spirit of the claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent, is:
