'SPECIFICATION forming' part of Letters Patent No. 536,938, dated April 2, 1895.

pplication filed December 1, 1894. Serial No.'530.541. (No model.)

To mil whom it may concern:

Be it known that I, RoMULUs RUFUs RIGH- MOND, a citizen of the United States, residing at Chariton, in the county of Lucas and State of Iowa, have invented certain new and useful Improvements in Burial-Derricks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it' appertains to make and use the same.

This invention relates to improvements in derricks or apparatus for lowering ooffins into graves or raising them out of the same, and the objects that I have in view are, first, to provide simple means for lowering a coftin into a grave with safety and ease, which apparatus can be operated by one man, and which can be used for disinterring or raising a heavy metallic casket or other kind of coffin from the bottom of the grave to the surface of the ground, by the aid of one or two men; secondly, to enable the lowering straps or cables to be readily Withdrawn from beneath the coffin without disturbing the latter when at rest on the bottom of the grave or Vault; and to provide safety appliances, by which the descent of the coffin can be arrested or governed to enable the cofiin to be deposited with safety into the grave.

With these and such other ends in view as pertain to my invention, it consists in the construction of the' spools or drums, on one of the longitudinal shafts, With slidable heads or Sections adapted to detachably clamp one end of each of the lowering traps or oables to one of said spools or drums, combined with mechanism to shift all of the slidable spool Sections simultaneously into and out of engagement with th'e fixed spool sections, whereby the ends of the straps or cables may be 1'e-' leased from series of spools to enable them to be wound' on the series of spools on the other shaft and thereby be withdrawn from the grave and beneath the coffin withoutdisturbing the latter.

The invention further ,consists in the novel combination of devices, and in the peculiar construction and arrangement of parts, which will vbe hereinafter fully described and claimed. i

To enable others to more readilyl understand my invention, I have illustrated the preferred 'forithe purpose of more clearly showing the construction thereof. Fig. 2 is a perspective View with the casing in position around the operative devices. Fig. 3 is an elevation looking at one end of the apparatus. Fig. 4.- is an elevation looking at the other end of the apparat'us. Fig. 5 is a Vdetail sectional view of one of the sectional spools or drums. Fig. 6

is a detail sectional view, taken through one of the side sills and one longitudinal shaft, to show the brake mechanism. Fig. 7 is a detail sectional view of the clutch'and sprocket wheel for shaft B.

Like letters of reference denote corresponding parts in all the figures of the drawings, referring to which- A designates the horizontal, main frame of the burial apparatus, which frame consists of the longitudinal side sills, a, and the transverse end sills, a', which are suitably united together to present a substantial, rigid structure of such dimensions as to surround the open, upper end of the grave or Vault into which a coffin is to be lowered. At the angles or corners of this horizontal main frame, which is substantially rectangular in Outline orform, are provided the braokets, b, b', the brackets at opposite corners, on each side of the frame, A, being arranged in line with each other. These aligned brackets, b, b', on each side of the horizontal frame are provided with shaftbearings, c, c', and in each pair of bearings of the corresponding brackets is journaled a shaft. As two pairs of brackets and bearings are provided on the frame, A, I-am able to provide the proper support for the two longitudinal shafts, B, O, which'are necessary for the proper operation of the apparatus or derrick. These shafts B, O, are disposed longitudinally of the frame, A, at the respective sides thereof, and they are parallel to each other, as clearly shown by the drawings.

The shafts are sustained at points intermediate of their length by means of thesupporting arms, d, d', the arms d being securely fastened to the longitudinal sill, a, on one side IOO of the frame, A, while the other arms d' are likewise fastened to the other sill, a, on the opposite side of said main frame, both the arms, d, and d', being arranged to overhang the sills a, a, and properly spaced apart, and provided with bearings at their upper free ends, through which bearings the shafts, B, O, are passed, so that the s'hafts B, O, are properly held and braced by the arms (Z, d', and by the brackets, to enable the shafts to stand the strain to which they are snbjected in the practical operation of the derrick. These shafts B, C, carry two or more pairs of spools or drums, although I have shown three pairs of spools in the drawings, but the number of spools or drums is not material and can be varied or changed at pleasure. The spools or drums forming each pair are carried by the respective 'shafts, B, O, and they are arranged iu line with each other. transversely across the main frame, A, of the derrick. The first pair of spools, is iudicated at D, D', the second pair at E, E', and the third pair at F, F', of which pairs of spools those designated by the reference letters D, E, F, are fixed to the shaft, B, while the other spools, D', E', F', are carried by the other shaft, C, whereby the spools are arranged in series on the lon gitudinal shafts on opposite sides of the frame, A, and the two spools forming each pair are in line with each other transversely across the frame, A, to enable the lowering straps or cables G, I'I, I, to be properly connected to, and wound upon,the spools forming the proper pair to accommodate each strap or cable. These lowering straps are continuous or un' broken throughout their length, and one end of each strap is fastened or secured in any suitable way to one of the spools on the shaft, B,while the other end of said strap is detach- -ably clamped to one of the sectional spools on the outer shaft C, to enable them to be wound on the spools of shaft B, and thereby permit the straps to be withdrawn from the grave and beneath the coflin, after the latter has been lowered into the grave, and withoutdisturbing the same when at rest upon the bottom of the grave or Vault.

The spools D, E, F, on the shaft B are each made in a single solid casting, or otherwise suitably constructed, as may be approved by those skilled in the art; while the other series of spools, D', E', and F' on the shaft O are made with separable heads or in sections constructed to clamp the ends of the straps or cables to be attached to said spools on the shaft C. In Fig. 4 of the drawings, I have shown in detail one of these sectional spools or drums, by reference to which figure it will be noted that the spool consists of a sleeve, h, a head, rigid or integral with the sleeve, and a slidable head or disk,j, which is provided with a looking key or stud, j', adapted to take or lit into a key-seat, h', formed in the sleeve h, whereby the end of the strap or cable may be fitted over the sleeve, h, and the slidable head or disk,j, can be adjusted toward the sleeve, so that its stud or key, j', will take or bind upon the end of the strap to detachably elamp the strap or cable to the sectional spool.

Although I have shown and described the sectional spool as provided with the key-seat in the spool, h, and the slidable head formed with the projecting key or stud,j' as the preferred embodiment of this part of my invention, yet I do not desire to strictly conline myself to this particular form of the sectional spool constructed to detaehably elamp one end of the lowering Strap or cable to itself, because I am aware that this precise form of the sectional spool may be modified without departing from the spirit of my invention.

It is desirable that all of the straps or cables forming the series G, II, I, shall be Simultaneously released from their spools D', E', F', when the straps are to be withdrawu from beneath the coffin after it is lowered, and to accomplish this simultaneous release of the straps, I have provided an Operating lever, I, and connections between said lever and the slidable seetions,j, of the spools on the shaft, O. Each slidable section,j, of the spools D', E', F', is provided with a hub, 7a, which is extended a suitable distance laterally from the head,j, and in this projecting hub or boss, 7a, is formed an annular groove or channel, k'. In the channels or grooves of the slidable sections of the spools on the shaft O are fitted the forked or bifurcated ends of the shipping levers, J, which are fulcrumed at intermediate points of their length, as at J', to the blocks or supports, J, fixed to one of the longitudinal sills, a, of the main frame A.

The Operating lever I is fulcrnmed atl its lower end to a suitable stand, I', on the frame A, and to this lever is connected one end of a pitman, L, which extends to and eonnects with one end of the shipping lever J of the spool D'. Another link L', extends from the first shipping leverJ to the second shipping lever, J, of the middle spool, f', and a third link, L, extends from the shipping lever, J, of the middle spool to the third lever, J, of the spool F', whereby the shipping levers J, J, J,of the spools D', E', and F'are connected in series by the rods L, L', L, to the operat' ing lever, I, so that one movement of the op' eratinglever will move all the slidable sections,j, of the spools, D', E', F', into or out of engagement with the rigid or fast members, h, of said sectional spools.

The two longitudinal shafts, B, C, of the derrick or apparatus are geared together for simultaneous rotation by means of the sprocket Wheels and chains shown in the drawings. At one end of the frame A, and the shafts, B, O, is provided the endless sprocket chain, M, which passes around the sprocket wheel, m, on one end of the shaft, B, on one side of the frame, A, while the other part of the sprocket chain, M, passes beneath and engages with a sprocket wheel, n, on one end of the shaft, O, this part of the sprocket chain, M, passing over the idler, guide, sprocket ICO IIO

` sprocket chain, M', which passes around the sprocket wheel, m', on the end of the shaft B,

and beneath the sprocket wheel, n', on the shaft, O, so as to engage with the teeth of the wheel, n', and over the two idler sprocket Wheels, 03, 04, secured to the bracket, b', by means of short axles situated on opposite sides of the shaft, O, and its driving sprocket, n'.

'The shaft, B, is further provided with a sprocket wheel, P, around which passes an upright endless sprocket chain, Q, which, at

its upper end, passes around and engages,

with a driving sprocket wheel, q, on a short horizontal power shaft, Q'. This shaft Q' is journaled in fixed bearings on an upright supplementary frame, Q, attached to the main frame, A, on the same side thereof as the shaft B, and this power shaft Q' is provided with a crank handle, q, by which the shaft, the sprocket chain, and wheels can be conveniently rotated to turn the shaft, B, for the purpose of winding the straps or cables on the spools D, E,'F, to withdraw said straps or cables from beneath the coftin.

Vhen the lowering straps are to be wound on the spools of the shaft B, after the coffin has been lowered and :the straps have been disconnected from the spools, D', E', F', of the shaft O, it is desirable to rotate the shaft, B, on which the straps or cables are to be wound in withdrawing them from beneath the coffin, without Operating the shaft, O, or the spools from which the straps have been disoonnected; and to accomplish this end,the sprocket wheels, m, m', on wthe shaft, B, are provided with clutches, r, r', that are fitted to slide on the shaft, B, and provided with projecting bosses r in which bosses are fitted the forked en ds of the shipping levers, R, fulcrumed on suitable blocks attached to the sill, a, beneath the-shaft B. These shipping levers, R, for the two sprocket wheels, m, m' on the shaft B, are connected by means of the connecting rod R', and to this connecting rod R', is pivoted an Operating lever, R, fulcrumed on the frame, A.

To regulate or control the rotation of the shafts in lowering thecoffin into agrave,I have provided the brake mechanism shown by Figs. 1, 2 and of the drawings. This brake mechanism consists of the wheel or disk, S, the brake lever S', and the Operating shaft S. The brake disk or wheel, S, is fixed to the shaft, C, inv any suitable Way, and the lever, S', is curved,'bent, or otherwise provided with the brake shoe, 8, which is curved to conform, approximately, to the contour of the brake wheel. One end of said brake lever is hung orfulcrumed to the short stand, s', fastened to the frame A, and the other end of said le ver is prolonged to form the arm, s, in which is formed the slot s'. The Operating shaft S' is arranged in an upright position near one end of the frame, A, and its lower part is reduced to form the long tenon, t, and the shoulder, t' said tenonrt being externally threaded and fitted in a fixed nut,T, secured to one end sill, a', of the frame A. This threaded tenon, t, passes through the slot, 8', in the brake lever, so that the shoulder, 25', of the stem or shaft, S,will bear upon the long arm of 'the brake lever, and when the shaft is rotated in one direction, the shoulder t'bears down on-the 'long arm of the brake lever and forces the brake shoe into close engagement with the brake wheel on the shaft, O, whereby the rotation of the shaft can be arrested or retarded to control the descent of the coftin into the grave or Vault.

This being the construction of my improved burial derrick or apparatus, the operation may be described as followsz-The apparatus is adj usted or placed over a grave or Vault so that the open, upper end thereof is inclosedv by the frame, A,-with the shafts B, O, extending len gthwise of the grave, on opposite sides thereof. Previous to placing the coffin in position to be lowered, the crank handle of the shaft Q is operated to wind the cables G, H, I, equally on the series of spools on the two shafts B, O, and then the brake, is applied to hold the shaft O against turning, which shaft, O, as it is geared to the shaft B, prevents all the spools forming the two series from turning when the coftin is placed on the straps or cables, G, H, I, the latter being stretched across the frame A, between the two shafts B, C. The coffin can now be placed upon the straps or cables, within or between the sills, a, a', of the frame, A, and the shaft, Q, and brake can now be operated to permit the coffin to descent by its own weight, the speed of descend being regulated by the brake mechanism. As the two shafts are geared for simultaneous operation, and the cables or straps have' been previously wound equally on the two series of spools, the coffin is lowered, in a horizontal position, into the grave or Vault, and with entire safety. After Vthe coffin is lowered and it rests upon the bottom of the grave, the apparatus is adjusted so that the cables or straps can be withdrawn without disturbing the coffin. This is done by Operating the lever, I, to throw the shipping levers J to a position where the slidable sections of the spools D', E', F',are disconnected from thefixed Sections, and thereby release the cables or straps from the sectional spools, and the lever R is operated to unship the clutches'r, r' from the sprocket wheels, m, m', on the shaft B, thereby throwing the two shafts B, O, out of gear. The crank handle can now be turned to rotate the power shaft and the shaft B, thereby coiling the straps or cables on the spools, D, E, F, and withdra'wing the same from beneath the casket at rest in the bottom of the grave.

IOO

IIO

It will be noted that the Operating mechanism for rotating the shafts B, O, that the stem for controlling the brake, and that the lever for disconnecting the gearing between the two shafts B, O, are all located at one end of the apparatus or derrick, and the sexton or attendant is thus able to operate and control the apparatus from one end thereof and without moving from one position to another.

In the practical construction of my apparatus or derrick it is designed to house or inclose all the working parts, except the two operating levers, I, R, and the driving mechanism for the shaft B, within a suitable casing, which is slotted to accommodate the movement of the lowering straps or cables. This casing is shown in Fig. 2 of the drawings, but for the sake of clearness, the casing has been omitted from Figs. 1, 3, 4 and of the drawings.

l'Vhen it is desired to disinter a coffin or casket, the grave is opened in the usual way, and the apparatus adjusted over the same. A hook is now inserted beneath the head of the coffin, to raise it and permit one of the straps to be adjusted beneath the same, and the foot of the coffin is likewise raised to receive another one of the straps. The gearing is adjusted to connect the two shafts together, and the crank handle is turned to rotate the two shafts in opposite clirections siinultaneously so as to wind the straps equally on the spools of the two' shafts. The cofiin can thus be raised evenly and safely to the surface, and the apparatus can be used to ad- Vantage in raising a light weight coffin or the heaviest metallic coffin made, which is very desirable as dificulty is sometimes experienced in disinterring heavy caskets.
