APPARATUS FOR MANIPULATING GRAVE-VAULTS.

SPECIFICATION forming part of Letters Patent No. 543,073, dated July 23, 1895. Application filed A art, 1895. Serial No. 544,382- (No model.)

To all whom it may concern.-

Be it known that I, J OSEPH A. WORK, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Apparatus for Manipulating Grave-Vaults, of which the following is a specification, reference being had therein to the accompanying drawings. 1

This invention relates to an apparatus for lowering grave-vaults or caskets into graves and for raising them out of graves.

It is very desirable that the unseemly exertions of gravemen incident to lowering the present heavy grave-vaults, usually made of steel, into graves be entirely done away with for the better order of the solemn occasion. Thesevaults are very heavy, weighing from three hundred to 'four hundred pounds, as a general thing, which, with the weight of the coffin and body, make them difficult to quietly and steadily lower, particularly when the ground is damp and soft about the edges'of the grave, as it frequently gives in from the pressure of the gravemen standing about the grave.

My apparatus consists essentially of two leading features, namely: a hydraulic lowering mechanism and a'more strictly mechanical hoisting mechanism, as more fully hereinafter described, and particularly" pointed out in the claims.

In the accompanying drawings, on which like reference-letters indicate corresponding parts, Figure l is a partial elevation and Vertical sectional View of my improved apparatus adjusted to lower a grave vault into a grave. Fig. 2 is a horizontal sectional view on the line 0000; Fig. 3, a horizontal sectional view on the line y y; Fig. t, a side elevation of the apparatus with a vault indicated in said view, and Fig. 5 a modification.

The letter A designates a pair of legs or standards adapted to be spread apart at the bottom and overlapping at their upper ends where they are connected together, and the letter B a similar pair of legs so arranged.

By preference they are curved, as shown in Fig. 1, so as to straddle the grave to readily bring the mechanism more nearly over the grave. A stout annulus O has trunnions D, which pass through the overlapped ends of the standards and have thumb-screws E and F to prevent the standards from slipping off. Within this annulus O is another annulus G with trunnions H mounted in the annulus O transversely to the position of the trunnions D. This provides a universal motion, as the annulus O can swing on the trunnions D and the annulus G can swing on the trunnions H. Hence the apparatus supported by these trunnions can be directed in any direction desired in manipulating it for its intended work.

An outer liquid-case I is fitted to slide up and down in the annulus G, and is screwthreaded a portion of its length and has mounted on it a bevel gear-wheel J, screwthreaded to fit the threads of the case. By rotating the gear-wheel J in one direction or the other the case is raised or lowered. A bevel-pinion K is mounted on one of the trunnions D and provided with a crank L, so as to rotate the gear-wheel J. This part of the apparatus I term the hoisting mechanism, as it is used to hoist the vaults in a manner presently to appear.

The case I has a cap M carrying a petcock O, the latter being to admit atmospheric pressure to the interior of the case. The case also has a bottom P, which supports a cylinder Q within the case with an annular space between it and the case. A piston B. is fitted to the cylinder Q and its piston-rod S passes through the bottom P and a stuffing-box T formed with the bottom. A liquid U, preferably oil, though water will answer, is placed in the cylinder Q in sufficient quantity to fill it when the piston is at its upper position. A hand-screw V passes through the case I andlis tapered to close an orifice W in the cylinder Q; As long as the liquid isheld in the cylinder beneath the piston the latter cannot descend; but by manipulating the handscrew V the orifice W is opened and the liquid allowed to escape more or less rapidly, according to the rapidity it is desired that the piston and its rod shall have. A notched crossbar X is carried by the piston S, and links Y are engaged with the notches of the bar and thus connect with the piston-rod the holder Z, which preferably consists of a number of bands or strips of webbing a, connected by bars I) and converging so. as to connect at their ends with the respective links Y. This holder too is passed around the vault and arranged to embrace and sustain it.

Now, then, let it be supposed that it is desired to lower a vault into a grave. The apparatus is standing, as shown in the drawings, with the parts adjusted as there indicated. This is preferably done after the vault has been placed upon the cross-bars c, and as the apparatus will only weigh about seventy-five to one hundred pounds two men can set it in place in a very easy and quiet manner. The holder having been adjusted to the vault and engaged to the piston an attendant quietly turns the screw V, when the liquid slowly escapes from the cylinder into the case, allowing the piston to smoothly and slowly descend with its lead. When the casket is brought to rest upon the usual strips of wood in the bottom of the grave one end of the holder is disengaged from the cross-bar X in any desired manner and then drawn from under the vault and taken out of the grave either separately or'in the act of removing the apparatus.

It will have been seen that in order to lower the vault it is necessary to first withdraw the cross-bar c. This is done by slightly elevating the case I through the crank and gears when the said cross-bars are withdrawn.

Now, then, if it be desired to hoist a vault out of a grave the case I and piston-rod S are adjusted to the proper depth, and then the crank is turned and the gears manipulated to cause the gear .I to raise the case by the screwthreads.

It is obvious that the details of this apparatus may be varied without departing from my invention, and I wish therefore to be clearly understood as not limiting myself to r such details, the drawings being merely one exemplification of a complete and practical apparatus embodying my invention.

The petcock O, I would observe, is used to admit atmospheric pressure in order to cause the liquid to re-enter the cylinder when the piston R is forced from the lower end to the upper end of the cylinder,creating the action commonly called a sucking action. In this way the same liquid is used over and over again, being at one time displaced from the cylinder and at another drawn back into the cylinder. The piston is usually forced to up or in position by hand, the hand-screw V being fully opened at this time.

Referring now to Fig. 5, it will be seen that in this modification the case I is omitted and the cylinder Q exterior] y threaded to receive the gear-wheel J. In this form, also, the inner annulus is fitted to the cylinder, as shown at G, instead of to the case I, as in the other form. In the modification the liquid is not allowed to escape from the cylinder; but the piston is so constructed that the liquid may he allowed to escape above it, and thus the quantity of liquid in the cylinder beneath the piston be diminished just as the quantity is diminished or lessened in the other form,

though in the latter case by escaping from the cylinder. This underlying principle of lessening'the quantity of liquid beneath the piston is common, however, to both forms.

In the modified form the piston R has a valve S with a stem T, guided by a guide U, and having a head V to limit the descent of the valve. A yoke W has in it a valveactuating red X, adapted to screw down upon the valve-stem and open the valve to let the water escape up through the piston. The red X slides through the cap M and the pinion O. The rod is grooved, as shown at P, and the pinion has a keyp, so as to rotatably engage the rod. A crank-shaft q is mounted upon the cap M and has a pinion r, which meshes with and rotates the pinion 0. When it is desired to lower a vault this crankshaft is rotated and the red X screwed down upon the stem of the valve 5 to open it more or less. Then theliquid escapes up past the piston R. When the piston is forced back by hand the liquid settles through it and past the valve.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. In an apparatus for manipulating vaults, the combination with suitable standards, of a cylinder supported by said standards, and a piston rod and piston in said cylinder, devices to suspend the vault from the rod, and means to slowly discharge from the cylinder a quantity of contained liquid to allow the piston to lower its suspending devices and load into the grave.
