A rod having a turning knob at one end has bearing in both said bosses. A sleeve surrounds the rod and is keyed thereto. The sleeve has threads of opposite pitch at each of its ends. A nut is threaded on each end of said sleeve. Each nut is pivoted at each of its ends to a link of a lazy-tongs linkage. A second, inner casting provides support for the foregoing structure and has horizontal guides for the free ends of the links at the opposite end of said lazy-tongs unit.
5 Claims, 5 Drawing Figures EMBALMERS l-IEADREST This invention relates to a head rest for use by morticians in embalming or otherwise preparing a cadaver for burial.
It is an object of this invention to provide a head rest as aforesaid which is simple in construction, assembly and operation.
It is a further object of this invention to provide a head rest as aforesaid capable of a wide amplitude of adjustment with the adjustment as fine or as great as the operator may desire in order to accommodate the condition and proportions of .the particular cadaver.
The above and other objects will be made clear from the following detailed description taken in connection with the annexed drawings, in which:
FIG. 1 is a perspective view of the head rest as a whole;
FIG. 2 is an end elevation of the head rest of FIG. 1;
FIG. 3 is a section on the line 33 of FIG. 1',
FIG. 4 is a section on the line 4-4 of FIG. 3; and
FIG. 5 is a section on the line 55 of FIG. 3.
Referring now to FIG. 1, there is shown an outer casing member generally designated 10. This preferably is a unitary metal casting and aluminum is the preferred metal. The casing has formed therein a headreceiving trough 12 with depending side walls 14 and end walls 16 and 18.
The end wall 16 is provided with an integral boss 20, while the opposite wall 18 is provided with a similar integral boss 22. The boss 20 is drilled at 24 to receive a rod 26, the opposite end of which is rotatably received in a recess 28 in the boss 22. The rod 26 is provided with a turning knob 30 adjacent the boss 20.
A sleeve 32 surrounds the shaft 26 and bears at each end against the bosses 20 and 22. The sleeve 32 is secured to the shaft 26 by a set screw 34 which has a head suitable for receiving an allen wrench. The sleeve 32 has threads 36 adjacent the boss 20 and threads 38 adjacent the boss 22. Threads 36 and 38 are of opposite pitch. The threads 36 engage mating threads on a nut 40 while the threads 38 engage similar threads on a nut 42. Except for the pitch of the threads, nuts 40 and 42 are identical and are elongated on each side of the sleeve 32. v
A pair of links 48 are pivoted at opposite ends ofthe nut 42 by screws 50 while identical links 52 are similarly pivoted to the nut 40. The links 48 and 52 of each side are pivoted together by suitable securing means 54.
The opposite ends of the links 52 are pivoted to a pair of links 56 while the free ends of the links 48 are pivoted to a pair oflinks 58. The links 52 and 58 are joined by pins 60 which are surrounded by spacer sleeves 62, while a similar pin and sleeve arrangement 64, 66 connects the links 48 and 58. The links 56 and 58 on each side are connected by a simple pivot means 68.
It now becomes necessaryto describe the base plate which, in FIGS. 3 and 4, is generally designated 70. The base plate 70 preferably is a single, integral aluminum casting having a central arched section 72 having a central opening 74 which provides access to the set screw 34 when the device is in fully lowered or collapsed position. The arch 72 extends into slightly divergent legs 76 which individually join horizontal rectangular portions 78. At their free ends the portions 78 have lateral extensions 80 into which are inserted the stems of rubber suction cups 82. The cups 82 assist in securing the head rest as a whole to the usual cooling board.
There are, of course, a pair of links 56 and 58 at each side of the casing 10. The free ends of the links 58 are joined by a pin 84 and are spaced by a sleeve 86 freely rotatable on the pin 84 and having rolling bearing or contact with a portion 78 of the base plate 70. A similar pin 88 and sleeve 90 join and space the free ends of the links 56. This permits the free ends of the links 58 to approach the free ends of the links 56 as the casing 12 is raised upwardly by turning the knob 30 to cause the nuts 40 and 42 to approach each other as previously described. I
In order to prevent separation of the outer casing 10 with its associated parts from the base member 70, pins 92 are provided, as best seen in FIGS. 3 and 5. Pins 92 have their ends turned down to provide bearing studs 94 which, as shown in FIG. 5, enter apertures 96 formed adjacent the lower longitudinal edges of the links 56 and 58. When in position, the anchored links 56 and 58 together with their associated parts have rolling contact on the inner surface of the legs 76 and the arch 72. The pins 92 may be installed by fully assembling the linkage which is connected to the uppercasing 10 by the rod 24 and using a jack to spread the links 56 and 58 on each side until the studs 94 may enter the apertures 96. As an alternative, either of the pins 88 or 84 may be left out which will permit spreading of the free ends of the links 56 and 58 sufficiently to permit installation of the pins 92 after which the pins 84 and- /or 88 may be installed to complete the assembly.
While various specific details have been discussed hereinabove, it will be clear that various modifications of detail will suggest themselves to anyone skilled in the art who may peruse this disclosure. It is not intended, therefore, to limit the invention to the precise details described herein.
