10 Claims.

This invention relates 'to biers and in -=par=- ticular 'to biers adjustable to accommodate various sizes and heights of caskets and contractable to admit of convenient mobility.

One object of the invention is to provide a bier which maybe expanded or contracted to accommodate itself to support caskets of various sizes and shapes and which may be contracted into a readily portable unit.

Another object of the invention is to provide a bier adapted to accommodate itself to support all sizes of caskets which is readily and easily adjustable to support deep or shallow caskets at a desired height.

Another object of the invention is to provide a bier that may be readily adjusted to support caskets of various sizes and shapes at vari'dii's heights in accordance with the weight of any casket placed thereon.

Another object of the invention is to provide a bier adjustable to support various sizes and shapes of caskets at a desired height and which is adapted to be readily and thoroughly secured in its adjusted position.

Other objects of the invention will become apparent by reference to the following detailed description taken in connection with the accompanying drawings, in which:

Fig. 1 is a top plan view of a bier embodying the invention shown in its fully extended position with certain portions thereof cut away to better show the invention.

Fig. 2 is a side elevational view of the embodiment of the invention shown in Fig. 1 shown in its fully extended position.

Fig. 3 is a top plan View of the novel bier disclosed in Fig. 1 shown in its fully contracted position.

Fig. 4 is a side elevational View of the novel bier disclosed in Fig. 1 shown in its fully contracted position.

Fig. 5 is a detailed sectional view taken on the line 5-5 of Fig. 1.

Fig. 6 is a detailed sectional view taken on the line 6--6 of Fig. 2 showing the novel means for readily adjusting the height of the bier and securing the said bier in its Vertical adjusted position.

Fig. 7 is a fragmentary sectional view showing the use of a long handled set screw for securing the casters at the ends of the central panel in their adjusted position.

Referring now to the drawings wherein like numerals refer to like and corresponding parts throughout the several views, the embodiment of the invention disclosed therein comprises, in general, a bier composed of a vertically disposed central panel Ajtwo pairs of vertically disposed intermediate panels B, and four vertically disposed end panels C, one pair of the "said intermediate panels B being "slida'bly and retatably extensible with respect to each end of the said central panel Agand one of the said end panels C being slidably and rotatably extensible with respect to each of the said intermediate panels 10 B. Thesaid panels A, B and 'C are preferably constructed 'of wood or m'etal either with solid centers as shownin the drawings or in the style of rectangular frames, all according to the architectural "effect 'de'sired.

The central panel A is provided with a top and bottom guide plate I'll having four guide slots ll therein through which pivot pins of the intermediat'e panels 13 are positioned as indicated in the drawings and as hereinafter described. The said central guide plates I'O are preferably secured to the top and bottom of the central "panel A by such means as countersunk head screws 52. The said central guide plates ifi are sufficiently wider than the central panel A to permit the H guide slots 11 thereof to be laterally spaced outside the said central panel A a distance slightly greater than one-half of the thickness of the intermediate panels B to permit the said intermediate panels B to be guided by the pivot pins thereof telescopingly between the said upper and lower central guide plates ill without scratching, marring or otherwise harming the finish of the sides of the said central panel A.

Each intermediate panel B is provided with a top and bottom guide plate It having a guide slot i4 therein laterally spaced outside the said intermediate panel B a distance slightly greater than one-half the thickness of the end panels (3 to permit the said end panels 6 to be guided 40 by the pivot pins thereof telescopingly between the said upper and lower intermediate guide plates l3 without scratching, marring or otherwise harming the finish of the sides of the intermediate panels B. The said intermediate guide 45 plates 13 are secured to the top and bottom of the said intermediate panels B by such means as countersunk head screws [5.

It will be noted that the height of each intermediate panel B plus the top and bottom guide plates l3 thereof is slightly less than the distance between the central guide plates l9 secured to the top and bottom of the central panel A to permit the intermediate panels B to be guided alongside the central panel A in telescopic relationship with respect to the said central guide plates ID on the top and bottom of the said central panel A. Also, the height of each end panel C is slightly less than the distance between the top and bottom guide plates l3 of the intermediate panels B to permit the said end panel C to be guided alongside the said intermediate panels B in telescopic relationship with respect to the intermediate guide plates l3 on the top and bottom of the said intermediate panels B.

The inner end of each intermediate panel B is preferably provided with a vertically disposed pivot pin iii which extends through one of the slots H in the upper and lower central guide plates 10 as best illustrated in Figs. 1 and 2 by means of which the intermediate panels B are guided to any desired adjusted position along the central panel A from the fully extended position shown in Fig. 1 to the fully contracted position shown in Fig. 3. An anchorage nut ll threaded on the bottom of each pivot pin it is preferably used to clamp the said intermediate panels B between the upper and lower guide plates ID in any position with respect to the said central panel A to which they may be adjusted.

The inner end of each end panel C is preferably provided with a vertically disposed pivot pin [8 which extends through the slot it in the upper and lower intermediate guide plates l3 of an intermediate panel B as best illustrated in Figs. 1 and 2 by means of which the end panels C are guided to any desired adjusted position with respect to the intermediate panels B from the fully extended position shown in Fig. 1 to the fully contracted position shown in Fig. 3. An anchorage nut 19 threaded on the bottom of each pivot pin [8 is preferably used to clamp the said end panels C between the upper and lower guide plates 13 in any position with respect to the panel B to which they may be adjusted.

In addition to the pivot pins it and I8 serving as means by which the intermediate panels B and the end panels C may be guided in any desired position with respect to the central panel A and intermediate panels B respectively, the said pivot pins 16 and I8 permit the said intermediate panels B and end panels C to be pivoted at any desired angle with respect to the central panel A and intermediate panels B respectively. The combined sliding and pivotal adjustment of the intermediate panels B with respect to the central panel A and the combined sliding and pivotal adjustment of the end panels C with respect to the intermediate panels B permits the bier to be adjusted any size from a maximum extended position as indicated in Figs. 1 and 2 to the minimum contracted position as indicated in Figs. 3 and 4.

A preferably rubber casket support 26 is provided at the top of the said central panel A near each outer end thereof, and a single preferably rubber casket support 2i is provided on the top of the extreme outer end of each end panel C. It will be noted that the supports 2| are higher than the supports 22 in order to compensate for the lower height of the top of the end panels C with respect to the height of the central panel A so that the top of all the said casket supports 2i and 22 will be at the same elevation.

A rubber tired caster 22 is preferably mounted on the bottom of the extreme outer ends of the central panel A and a like rubber tired caster 23 is mounted on the bottom of the extreme outer end of each end panel C as best indicated in Figs. 1, 2, 3 and 4 to permit the bier to be easily moved either in its expanded, partially expanded or contracted position.

It is preferable to provide means by which the bier may be easily and readily adjusted to a desired vertical height and it is extremely desirable to have the said means for vertical adjustment capable of causing the said bier to automatically compensate for the various heights of caskets placed thereon. Large caskets are generally constructed deeper than smaller caskets and the larger caskets weigh more proportionately than do the smaller ones, therefore, the weight of the various sizes of caskets is substantially a direct function of the height thereof. With this fact in view a novel self vertical adjustment of the expandible and contractible bier disclosed herein may be accomplished as disclosed in Figs. 6 and 7.

The bier is preferably provided with casters 22 at the extreme outer ends of the central portion A and casters 23 at the extreme outer end of each of the end panels C which may be spring mounted in the said panels A and B as best indicated in Fig. 6, the construction shown in Fig. 6 particularly applying to the mounting of the casters 23 in the extreme outer ends of the end panels C.

Referring now particularly to Fig. 6, the outer end of the end panel C is bored and counterbored from the bottom to receive a caster mounting sleeve 24 and provide a suitable space 25 into which the upper portion 26 and stop 21 of the stem 28 of the said caster 23 may reciprocate. The caster 23 comprises a preferably rubber tired wheel 29 rotatably mounted in the caster fork 30 disposed below a shank 3| from which the stem 28 of the caster 23 upwardly extends into the caster mounting sleeve 24. The caster stem 28 is telescoped snugly into the lower end of the caster mounting sleeve 24 while the upper portion 26 of the said caster stem 28 which is smaller in diameter than the lower portion of the caster stem 28 is telescoped through a suitable aperture provided in the top 32 of the said caster mounting sleeve 24 as best illustrated in Fig. 6. The upper portion 26 of the said caster stem 28 is smaller in diameter than the said lower portion of the said caster stem 28 to admit of a compression spring 33 being positioned therearound in the upper end of the said mounting sleeves 22. The said compression spring acts against the shoulder 34 at the top of the lower portion of the caster stem 28 and reacts against the inside of the top 32 of the said caster mounting sleeve 24 and normally urges the caster 23 to a depending position with respect to the bottom of the end panel C.

The lower portion of the said caster stem 28 is preferably provided with a plurality of spaced annular semi-circular grooves 35 as best indicated in Fig. 6 into which a semi-spherical ended set screw 36 threaded in the sleeve 31 projecting through one side of the panel C is positioned in such a relationship with respect to the said stem 28 of the caster 23 as to prevent the caster 23 from telescoping out of any adjusted position to which the said caster may be set with respect to the bottom of the bier and at the same time permit the caster and stem thereof to turn within the said caster mounting sleeve 24. It will be noted that the radius of the semi-spherical end of the set screw 36 is preferably slightly less than the radius of the semi-circular grooves 35 in the caster stem 28 to prevent the set screw 36 from looking the said caster sleeve 28 against turning in its mounting sleeve 24.

In the embodiment of the invention disclosed in the drawings each of the six compression springs 33 used are of such strength as to compress to the position indicated in Fig. 6 when the maximum size and Weight of caskets is positioned on the bier. The stem of each caster is telescoped within the caster mounting sleeve 24 thereof as indicated in Fig. 6 when the weight of a. maximum size and weight of casket is placed on the bier and also when the bier is not in use. In order to maintain the said casters 23 in their retracted position, the set screw 36 is turned into engagement with the lower annular groove 35 of each caster stem 28.

In order to avoid the set screw 36 from fouling the intermediate panels B when the bier is contracted or adjusted to a semi-contracted position, a set screw 35!? with an elongated shank 36| is provided at the ends of the said center panel A, otherwise, the construction of casters 22 at the ends of the center panel A are identical to the construction of casters 23 with the additional exception that the shank 3H] of each of the casters 22 is shorter than the shank 3! of the casters 23 to compensate for the extra depth of the central panel A as compared to the depth of the end panels C.

When using the adjustable bier, the said bier is first adjusted in width and length to accommodate the casket to be placed thereon and the anchorage nuts l7 and iii are securely drawn up. The set screws 35 and 31 are released and the bier is extended vertically to its highest position on the casters 22 and 23, the stops 2'! preferably threaded on top of the upper portion 26 of each of the stems 28 of the casters 22 and 23 serving to maintain the bier level in its highest position. The casket is then placed on top of the bier, the weight of which causes the bier to settle to the normal desired height. The set screws 36 and 36B are then turned so that the semi-spherical end thereof registers with one of the spaced annular grooves 35 in the lower portion of the stem 28 of each of the casters 22 and 23.

t is readily observed that the bier may be extended to the desired size, a casket placed thereon and adjusted to the desired height with a minimum of confusion and effort. Also, once adjusted the height to which the bier is set cannot be varied without the release of the set screws 36 or 368, yet, the casters are free to turn in their mountings making the bier easily portable after adjustment. Also, if a height is required other than the normal height to which the bier automatically positions itself after a casket is set thereon, any new height may be established Without the necessity of those adjusting the height of the casket lifting a total Weight of the casket inasmuch as the compression springs 33 are of the correct strength to receive some of the weight of the caskets during vertical adjustment thereby making the adjustment of the height of the bier to suit required or desired conditions very easy to accomplish after a casket has been placed thereon.

Although but one embodiment of the invention has been disclosed and described herein, it is readily observed that many changes including the size, shape, arrangement and detail of the various parts thereof may be made without departing from the spirit of the invention as defined in the appended claims.
