BEDSTEAD END.
T 0 all whom it may concern Be it known that I, ALANsoN C. NOBLE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Bedstead Ends, of which the following is a specification.
This invention relates to bedsteads, and the object of the invention is to obtain a metal bedstead end which may be used independently of or in combination with an ordinary bedstead end by means of which the side rails and mattresses of the bed may be raised at one end, or tilted.
The necessity of raising one end of a bed is found when the person occupying it is ill, and particularly after a surgical operation, making a bed which is provided with this device especially adapted for hospital use.
Further objects of the invention are to obtain a bedstead end of the kind named which is simple in construction, strong and durable, of good appearance, not liable to break or get out of order, and economically made.
In the drawing Figure 1 is a horizontal section of the posts of a bed end embodying this invention, showing the end rail and connected parts in top plan View. Fig. 2 is an end elevation of a bed end embodying the invention. Fig. 3 is a side elevation of a bed end. Fig. 4.2 is a vertical section on line 4iof Fig. 2, viewed in the direction indicated by thearrows. Fig. 5 is a vertical section on line 55 of Fig. 1, viewed in the direction indicated by the arrows. Fig. 6 is a vertical section on the right hand side of the medial line of the part, and a front elevation of the left hand side of said medial line, of the casing which is located midway between the posts of the bedstead end. Fig. 7 is a sectional View on line 7-7 of Fig. 8, of a modification of the construction which is illustrated in Figs. 1 to 6, inclusive, viewed in the direction indicated by the arrows. Fig. 8 is a vertical section on line 88 of Fig. 7 viewed in the direction indicated by the arrows. Fig. 9 is a vertical section of the hol- 10w posts and mechanism therein forming elements of the construction illustrated in Figs. 7 and 8, viewed at an angle of ninety degrees from said Fig. 8. Fig. 10 is an elevation, (on the right hand side as viewed), and a vertical section, (on the left), of an additional modified construction embodying Specification of Letters Patent.
Application filed August 26, 1912.
Patented May 12, 1914.
Serial No. 717,071.
this invention.- Fig. 11 is a horizontal section of a casing and a top plan View of gearmg therein, forming elements of the construction illustrated in Figs. 10, 12 and 13. Fig. 12 is a top plan view of the journal bearing of the screw threaded part of the bedstead legs which are illustrated in Fig. 10, and Fig. 13 is a side elevation of one part of said journal bearing. And Fig. 14. is a side elevation, viewed at an angle of 180 degrees from the view thereof in Fig. 9, of the inner movable part of the bedstead leg used in the construction illustrated in Figs. 7, 8 and 9.
Similar letters refer to similar throughout the several figures.
A, A, are casings.
a, a, are lugs on casings A respectively parts and B, B and G are pipes or tubes which are secured to said casings by being fitted tightly over said lugs.
D is a recess in casing A and E, Fig. 3, is a side rail of a bedstead which is secured to a bedstead end embodying this invention by entering the end thereof into recess D.
F is a casing which is provided with lugs f,
Pipes B, B form the outer part of the bedstead legs.
The pipes or tubes G are secured to casing F by being fitted tightly over lugs f, f, respectively. Lugs f, and a are respectively provided with a circular aperture (lettered G, Fig. 4) which constitute journal bearings for shaft H. Casings A and lugs 64 are provided with apertures which constitute bear ings for racks I respectively permitting longitudinal movement of said racks.
2' are casters on the lower ends of racks I.
J are gear wheels rigidly secured on shaft H so that the teeth thereof intermesh with the teeth of racks I.
K is a geared wheel rigidly secured on shaft H (in casing F) and L is aworm gear intermeshing with the teeth of wheel K. Z is the shaft of worm gear L and is ournaled in casing F.
M is a crank secured on shaft Z so that turning of said crank turns said worm gear, wheel K with which the teeth of which said worm gear engages, thus producing rotation of gears J and longitudinal movement of racks I.
The casings A and F and pipes or tubes C constitute one of the end rails of the bedstead of which the device forms a part and Cit said end rail is raised or lowered, by the longitudinal movement of the rack I, as last above described.
In the modification which is illustrated in Figs. 7, S and 5), a slotted inner tube or pipe (1), with rack (1) attached to the inner face thereof by rivets (i), is substituted for the rack it used in the construction already described; and an outer pipe (18"), is substituted for pipes 13, B. The pipe B extends continuously through casing A. Pipes B and I are made sutliciently large to permit the pinion J to be inserted in said pipe I. e' is a slot in said pipe I and shaft H extends through said slot.
In the construction which is illustrated in Figs. 10, ll, 12 and 13, the gears N, N, n, are substituted for gear K and worm L used in the hereinbefore described constructions, and the vertical screw threaded post or shaft 0, gears N n, on one end of the bedstead end and gears N, a, on the other end, are substituted forthe gear and rack previously described. Posts or shafts O, on opposite ends of the bedstead end are right and left hand threaded, as at O and O, and are nonrotatably mounted in bearings Q and gears LT and N. The part of said posts or shafts O which are not screw threaded is provided with groove P, in which groove feather or pin ;0 is inserted to prevent rotation of said shafts. Bearing Q is secured in the lower end of pipe, or post) B, by screws and feather or key 79 is contained in a recess provided therefor in said hearing.
The rotation of handle Min this construction rotates shaft-s H, H, in opposite directions, also beveled gears N and N. Shafts O are therefore respectively provided with right and left hand screw threads, so that said shafts will simultaneously move in and out of pipes or posts B, B.
The bearings T permit rotation of gear wheels N and N respectively, and said bearings consist of two parts, which are provided with an inner annular recess or groove 1?, 2, (Figs. 12 and 13), which fits the annular flange n on said gear wheels N, N. Bearings T are respectively secured in place in pipes 13 by screws T, and thereby,
while permitting rotation of wheels N, N prevent upward or downward movement thereof in said pipes; hence rotation of said gear wheels produce longitudinal movement of shaft 0.
Where a bedstead is at hand and in use I prefer to attach the end embodying this invention to one end of said bedstead; but in constructing a new bedstead I prefer to use said embodiment of the invention as the end of said new bedstead.
I claim:
1. A bedstead. end consisting of two-part leg members and a cross member, said cross member attached at its ends to said twopart leg members, in combination with means to change the relation of said parts of the leg members which are not attached to the cross member relative to the parts which are attached to said cross member, and to maintain said twopart members in said changed relation.
2. A bedstead end comprising vertical tubes, a horizontal tube attached to said vertical tubes by casings interposed between them and said vertical tubes, in combination with a rotatably mounted shaft extending through the horizontal tube, geared racks longitudinally movable in the vertical tubes, a worm gear and a worm screw connected to the said shaft to rotate said shaft, and gears on said shaft interrneshing with said racks.
In a bedstead end, casings, vertical tubes secured to said casings, an additional casing, and horizontal tubes secured to said first named casings and to said additional. casing, all said casings respectively provided with journal bearings and a shaft rotatably mounted in said journal bearings, a gear on said shaft and a worm in said additional casing intermeshing with said gear, a geared rack longitudinally movable in said vertical. tubes, and gears on said shaft interlneshing with said rack, and means whereby the shaft of said worm may be turned.
