15 Claims. (01. 214-ss) This invention relates to a hearse ofthe side delivery type wherein a mechanism is provided for supporting a casket within the hearse and for rotating the support in a manner to alter its position from a longitudinal position within the hearse to a transverse position. In order to alter the position of a casket within a hearse from longitudinal to transverse with respect the body, considerable space requirement is normally, required as well as the provision ofa rather wide opening through which the table supporting the casket can be moved.

It is an object of this invention to provide a mechanism which will alter the position of the casket supporting table with a minimum space requirement and with a minimum door opening.

It is another object of the invention to rotate the supporting table simultaneously with longitudinal movement thereof in a manner that the rotation bears a definite relation to the 1ongitu-' rotating the table bears a definite speed ratio to the gear mechanism for longitudinally moving the table so that the concomitant longitudinal movement and rotation alters the position, of the supporting table to one transversely of the hearse and extends the same therefrom.

It is another objectof the invention to provide a gear mechanism. for rotating a casket supporting table within a hearse and a lead screw and cooperating nut mechanism for longitudinally moving the supporting table wherein the gear mechanism is driven by and synchronized with the lead screw mechanism for producing a predetermined path of travel of the supporting table.

It is another obiect of the invention to provide a common prime mover which is reversible in its driving motion for changing the direction of motion of the table. v

It is another object of the invention to provide an electrical control mechanism for starting the operation of the table support mechanism and for selecting the direction of rotation of the table .to determine the side of the hearse throug which itwill extend. i v

The hearse upon which this invention is to be used is of the type commonly known as the side delivery type. In a hearse of this general type the casket is normally carried within the body of the hearse in a longitudinal position, and when the casket is to be placed into the hearse" or removed therefrom, the supporting table for the casket is moved into a position which is transverse with respect the hearsebody in a manner that a portion of the table extends from the side of the hearse. To permit the hearse body to be constructed as small'as possible it is essential that the sweep of the path through which'the'casket supporting table passes when changing from longitudinal to transverse posi-.

A similar thrust bearing is preferably provided in the bearing bracket '31 to take up thrust in a direction opposite to the bearing 46.

A worm wheel 44 is carried upon the forward end of the lead screw 36 and is engaged by a worm 45-drivenby an electric motor 46. The electric motor 46 is ,of-the-reversible type so that the lead screw 36 may be driven in either direction of ro- .tation' through the interconnecting worm and worm wheel; Suitable electrical mechanism hereinafter described is provided for reversing the current flow'through the electric motor 46.

.5 The upper wall 34 of the lead screw nut designated 13S 56 is provided with a vertical post 41 which is secured to the wall 34 many suitable mamf er. A central bore 5| is'provided within the body- 26* of the pivot post 24 through which the postfilektends; -' Recesses 52 and 53 are provided in'the upper and lower portions'respectively of the" body 26 in which there are positioned the ball bearings 49"arid respectively. The post 41 issuitably journaled within the'ballbearings 48 and '49" and carries a collar 54 upon the upper end thereof which'rests upon the ball bearing 49.

This bearing 49 thus provides a thrust bearing for the post 4T and the mechanism carried thereby. The mechanism thus far described provides means formoving the pivot post 24 longitudi- "2 4 longitudinally within the; slot-.21.? The' lead nally withinjth'e slot 2 whenever the lead screw 36 is rotated in one direction or the other depending upon the position of the table 2 [within thehearse'; i

The worm wheels 51 and 58 are both in engagement with the worm-'56 carried upon the lead screw 36 so that upon rotation of the lead screw 36 the worm 56 will drive the worm wheels 51 and 53 in opposite directions of rotation.

To permitthe worm 56 tomove longitudinally I uponthelead screw .36 while being driven there- 60 it t t screw nut 50 with respect the lead screw 66. consists of a wall. member 34 which is suitably 31Lpositionedtoward the forward-tend. of the hearse and is prevented from shifting longitudinallyof thefhe'arse by. meansof the collars 38 -which-are suitablyllsecured to the-lead screw 36.

the end ofthe lead screw extending through the bearing 3-9.and being supported by aballbearing 40. The ball bearing 40 is carried within a recess bya key-way is provided therein within which a suitable key 62 carried by the worm 56 is adapted to slide upon longitudinal movement of the lead 60a. The pinions 63 and 64 are freely rotatable upon their respective axle shafts 59'and 60 until engaged by a clutch mechanism hereinafter described.) The pinions 63 and 64 are in constant engagement with the internal gear 29 carried by I the pivot post 24 so that either of the pinions can drive the pivotpost 24 for rotation thereof depending upon the engagement of its cooperating'clutch mechanism.

The clutch mechanism between the worm wheels 51' and 58 and, the pinions 63 and 64, shown toga better advantage in the enlarged cross-sectional view of Figure 6, and since both of the mechanisms are identical only one is shown and described. The wall 33 of the lead screw nut 56 is provided with an internal bore 65 within which there is positioned a sleeve 66 carrying a pin 61 which extends radially toward the center of the sleeve 66. A second sleeve 68 is positioned within the sleeve 66 and is j ournaled upon the axle or stub shaft 59. An arcuate slot 76 is provided in the sleeve 68 into which the pin 6'! extends. A second slot 'II is provided in the sleeve 68 and is vertically positioned therein to receive a pin 12 which extends from the stub shaft 59. The sleeve. 66 is provided with teeth 73 in the outer periphery thereof and is engaged by a rack I4 for rotating the sleeve 66 with respect the sleeve 68.

A sleeve I5 is journaled upon the stub or axle shaft 59 and is provided with a plurality of splines 76. The sleeve i5 is supported upon the sleeve 66 by means ofthe splines 16 so that when the sleeve 66 is rotated by means of the rack 14 the cooperation of the pin 61 with the slot Ill moves the sleeve 66 upwardly carrying the sleeve I5. The Worm wheel 51 is providedwith' a splined internal bore '38 adapted to be engaged by the splines I6 of the sleeve 75 when the sleeve I5 is moved upwardly by means of the sleeve 66-.

The normal position of the clutch mechanism for de-clutching the. worm; wheel 51 from the pinion 63 is as shown in Figure 6 so that the worm wheel 51 can rotate freely without causing rotation of the pinion 63;

As heretofore mentioned each of the worm wheels 51 and 58 are provided withthe clutching mechanism which is described, the, clutching mechanism 51a. of the worm wheel 51. being actuated by the rack 14-while the clutching mechanism 58a forthe worm wheel 58 is actuated by the rack 140,. The racks I4 and 14a are interconnected by means of a yoke 19 so that actua tion of one of the racks actuates both whereby tie-clutching of one of the clutch mechanisms causes clutching of the opposite mechanism.

The racks I4 and 14a are actuated by means and 84a engage detents 85 and 85a in the racks l4 andl ta respectively.

The electrical system for controlling actuation of the heretofore described apparatus consists of the electric motor 46 driving the worm 45 for rotating the worm wheel 44 which in turn actuates'the screw 36. Rotation of the screw 36 causes the mechanism to function in a manner which will be hereinafter described.

The electrical controls consist of limit switches 86 and 81 one of which is positioned adjacent each end of the slot 21 in the floor 23 of the hearse a'nd is adapted to be engaged by the pivot post 24 when the same approaches the ends of the slot 21 whereby energization of the electric circuit to the electric motor 46 is controlled. The limit switch 86 deenergizes the electric motor 46 when the pivot post 24 has moved to its rearward'position, which position is indicated in Figure 1. The limit switch 81 deenergizes the electric motor 46 when the pivot post 24 is moved in its forward position representing the full ex-' trolling the outward movement of the table-2|, while the push button switches 98.are connected in parallel and control the inward movement of the table ZI. The electric motor 46 is of the reversible type and is shown in the electrical diagram of Figure 2. The direction of flow of current to the armature is always in the same direction while the flow of current to the field is re versed in order to obtain forward and reverse rotation of the screw 36 for moving the table 2| in or out of the hearse body Ill. The electric circuit for the motor 46 is energized from the battery 99 of the hearse. The limit switches 86 and 87 are normally closed unless engaged by the pivot post 24 so that the circuitshown in Figure 2 has the switch 86 in the open position representing the retracted position of the table 2I as of bellcrank levers 80 and 86a respectively which are pivotally carried upon the pivot supports 8! and Ma. The pivot supports 8! and 81a are secured to the under side of the floor 23 in any suitable manner as by the bolts 82 and 82a. The

lever 86 is provided with an actuating arm or;

rod 83 which is connected to or actuated by the side door I2 of the hearse. The lever 86a is rovided with an actuatingarm orrod 83a. which 83 has been moved by the .door I2 which is now closed while the lever 860. has been actuated by the door I9 to pivot the same about its-pivot support 8 la to actuate the rack I4. Figure 5 thus shows the position of the actuating arms 86 and 86a, one of which is in position with the door closed and the other is in position with the door open.

. To retain the racks I4 and 74a in position upon actuation thereof spring pressed balls 64 When the doors I2 and I3 are both shown in' Figure 1. The' push button switches 91 and 98 are of themomentary contacting type in order to energize the coil or 9| for closing the relay 92 which is provided with a holding circuit represented by the contact blade 93. The

relay 92, as shown in Figure 2, is in the normal deenergized position and is retainedin this posi- 'tion by means of the compression springs I60 which oppose each other to balance the position of the armatures .8 8 and 89 within their respective actuating coils90 and SI.

As will be seen from the former description the lead screw 36 and the worm 55 are driven by a common prime mover, the'electric motor 46 and thus the driving ratio between longitudinal movement of the pivot post 24 and rotational movement thereof can be preedetermined to providea definite increment of rotation of the pivot post 24 for. each increment offorward travel' extendsithe table. from one side orthe otherof the'hearse body'in accordance withthe predetermined direction ofrotation for the rotating operating clutching mechanism 58a in orderto raise the splined sleeve 15 whereby the worm Wheel 58 isplaced in driving engagement with the pinion'64. The push button 91 positioned 7 moved in a rearward direction and concomitantly rotated to retract the table 2| with the same motion provided for its forward advancement.

In Figures 7 to 10. inclusive there isshown a modified; form ofapparatus for producing the same typeof motion as produced by the apparatus heretofore described. The essential elements of adjacent the door I3 is actuatedto engage its cooperating contacts to close circuit to the coil 99 for actuating the armature 88 and thereby' pull the relay 92 in an upwardly direction to close circuit through the upperset of contacts for each of the blades 93, 94, 95 and'96. The blade 93 provides a holding circuit for the coil 99 so that when the push button 91 is released-the coil 90 will not become deenergized. The blades.

94, 95 and 96 control the direction of: flow of current to the armature and the field of the ele c'-" tric motor 46 so that the screw 36. is'rotated in the proper direction for advancing the table forward and outwardly of the hearse I9.

Sincethe clutch 58a. drivingly connects the worm wheel 58- withthe pinion rotation of the lead screw 36 also rotates the worm 55 for rotating the worm wheel 58. The pinion 64 being inconstant engagement with the internal gear 69 secured to the pivot post 24 will rotate the pivot post simultaneously with the forward advancement of the post by means of the lead screw 36. Since the driving ratio has been established between the lead screw 36; and the gearingmech anism for rotatin' 'thepivot post 24, the post 24 will be rotated a predetermined angular increment for each increment of forward motionthereof whereby the table2I is'moved forwardly and concomitantly rotated to advance and extend the same from the hearse body I0. When the pivot post 24 approaches theforward end of the slot 21 it will engage the limit switch 81 to open the circuit to the coil 90 whereby the relay 92 is z deenergized and the mechanism thus halted in its operation. I

When the table 2I is to be returnedto within thebody of the hearse the pushbutton switch 98' isjactuated' toclose circuit through its coope r ating contacts whereby circuit will be .made

the mechanisms are identical in that a lead screw isusedto produce longitudinal motion of the piv- 7 ot postwhile a worm and worm wheel arrangement is-provided for producing rotative motion of the pivot post. The lead screw and the worm are driven from a common prime mover, the worm obtainin its power from the lead screw and the two elements are driven in a predetermined speed ratio which produces predetermined 'rotativeincrement of the pivot post for each increment of longitudinal movement thereof.

In this arrangement the pivot post IIII carries a worm wheel III which is rotated by means 01 a worm II'2 carried upon a feed rod H3. The feed rod II3 has a key slot II4 adapted to engage a suitablekey in the worm I2 to permit the same longitudinal movement. along the feed rod II3 ,while'being' rotated thereby. 1

The pivot post IIIl .hasa depending portion -H5 whichextends below the worm wheel III and carriesan enlarged head H6. The head H6 is adapted to be positionedwithin a recess II'I provided in the lead screw nut I I8. A cover plate I I9 engages the upper surface of the head H6 and retains the same in cooperating engagement with the lead screw nut I I8. h

The feed rod I I3'which carries the worm I I2 is bearinged in a bracket I carried upon the lead screw nut I I8. A lead screw I is in threaded engagement with the lead screw nut I I8 through -a suitable, threaded bore I2I provided longitudinally in the lead screw nut H8. The lead screw I25 "carries a worm wheel I22 suitably secured thereto which is drivingly engaged by a worm I23;

which worm I23 is secured upon the shaft of an electric motor I24.

The electric motor I24 is of the reversible type to drive the lead screw I25 in either direction of rotation according to the movement desired for the casket supporting table 2L.

Y In'order to rotate. thepivotpost IIiI whilelongitudinally moving the-same withinfthe slot 21 in the floor 23 of. the hearseagear train is provided between the leadscrew, I25. and the feed rod H3. The gear trainthus. provides means for trans mitting power-from the electric motor I24 to the feed rod I -I.3 so that a common prime mover is usedfor driving the lead screw'I25 and the feed V V v V rod 143i: The gear train, is also adapted to functhrough the coil 9I since the limit switch-'86 is 7 now in the closed position. The armature 89 will I be moved in a downwardly dire ction to closethe blades93, 94, 95 and 96 upon the cooperating lower sets of contacts. .Theblade 93 provides a hold;

ing circuit fonthe c011 19Iwhile theblade 9,4,

as and as energize the electric motor 45, When the relay blades are in the lower positionithe direction} of. flow to'the armature to theelectric motor 46 is retained in thesamedirectiomas when the blades are in their upper position; However,

thedirection of flow of current to the field of the motor 46 is reversed to the direction of flow from when the blades are in their upper position. 7'

The lead screw 36. will thus be driven in an opposite direction of rotation vfrom that previously described whereby the pivot post 24. will be tion as means for reversing the directionof ro-' tation of the'feed rod I,I3,,with respect the lead screw. .I25 so t hat. the pivot post 9 can be rotated in either. direction of rotation forv extending the table. gtthrough the desired side ofthe hearseIIL V Theo-gear train consists. of. the spur gears I29 and I21 'carried upon theelead, screw I25 and -'-i s interpositioned between the gears I2'I and I29 in. order to reverse thedirection of rotation of the predetermined to obtain rotation of the pivot post I V I win predetermined increments for-each increrod I I3 rotatably drives the worm I I2 to cause rotation of the pivot post I ID, the power for such drive being obtained either through the gears I26 and I28 or the gears I21, I3I and I29. If the,

gears I26 and I28 are in meshing relationship as shown in Figure 7 the direction of rotation of the if the pivot post H9 is to be advanced toward the forward end of the hearse.

In order to return the casket table 2I to within the hearse the directionof rotation of the motor I24 is reversed in a manner heretofore referred to by the description of the electrical diagram shown in Figure 2.

A mechanism is provided for automatically selecting the direction of rotation of the pivot post H9 in accordance with which of the doors l2 or I3 is opened, thereby determining the side of the hearse through which the table 2| will extend. This mechanism consists of a shifting fork I32 which engages an under-cut portion I33 provided in the sleeve I36. The fork I32 is pivotally carrying a pin I36.

A pair of rods I31 and I39 extend transversely of the hearse I0 and are suitably carried in the bearing supports I39 andI49 respectively. Collars MI and I42 are provided on the rods I31 and I38 respectively and have compression springs I43 and I44 respectively positioned between the collars I4! and I42and their cooperating bearing posts I39 and I46 respectively.

The rod I31 engages the door I2 whileithe rod I38 engages the door I3 so'that upon opening of either of the doors the corresponding rod will be moved outwardly by its actuating spring. The inner ends of the rods I31 and I33 are provided with slots I45 and I46 respectively through which the pin I36 extends. The device, as shown in Figure 10, has been actuated by the door I3 to shift the gears I28 and I29 to one of their positions. If the door I3 is again opened there will be no actuation of the pinion I36 or the fork I32 since the slot I46 will permit movement of the rod I38 without engaging the pin I36. sult is obtained since the mechanism is arranged that once it has been shifted it will not move until the mechanism has been shifted in the opposite direction by the opening of the other door. Thus the arrangement of the device of Figure 10 is such that if the door I2 is opened the rod I31 will be actuated by the spring I43 whereby'the slot I45 engaging the pin I36 will cause the arm I35 to rotate the fork I32 and thus shift the sleeve I38.

Since the worm H2 is geared directly to the screw I the speed of operation thereof can be .40 mounted at I34 and has an extending arm I ment 1 of longitudinal travel thereof with respect the hearse body whereby a, predetermined path of travel for the casket table 2| created.
