TILTING BED-SPRING.

Specification of Letters Patent.

Patented June 18, 1907.

Application filed 'January 25, 1997. Serial No. 354,053.

To all whom it may concern.-

Be it known that I, ARTHUR LAWRENCE, a

citizen of the United ,States of America, and a resident of Chicago, in the county of Cook and State of Illinois, have inventedcertain new and useful Improvements in Tilting Bed- Springs, of which the following is a specification.

The main objects of this invention are to provide an improved form of-bedstead and tilting spring arranged'to permit the spring and mattress to be readily tilted on the bedstead to a position which will permit of conveniently swee ing or cleaning the floor under the bed wit out moving the bedstead; to provide simple and convenient means for hinging bed-spring frames of common structure to bedsteads, without necessitating changes in the structure of either the s ringframe or bedstead; to rovide a simp e and convenient device for olding the unhinged side of the spring-frame on a proper level with the hinged side when the spring is in the horizontal position when the bed spring is raised. These objects are accomplished by the device shown in the accompanying drawings, in which:

Figure 1 is a perspective view of a bedstead and tilting spring constructed according to this invention. Fig. 2 is a section of one of the clamps and stops secured to the movable side of the bed-s ring. Fig. 3 is asection on the line 33 of I ig. 4, showing one of the dlamps securing the hinged side'of the bed-spring to the side rail of the bed. Fig. 4 is a top plan of the clamp and rails shown in Fig. 5, the rails being partly broken away. Fig. 5 is a vertical section through the clamps 35and rail 34, showing the arm 33 of the spring 32, partly broken away, and in the position indicated by the dotted lines 37 in In the device shown, the bed posts 1 have thereon the usual socket castings 2, to which the

side rails

8 and 22 are attached in the usual manner. The side rail Sis clamped to the rail 9 of the bed spring frame, bymeans of the clamps, consisting ofthe

members

10 and 12. The

arms

10 and 12 are made to fit the angle iron of usual form which is used for forming the

side rails

8 and 9. The upper end of the clamp is turned over at 11 to engage the rail 9. The lower end has a similar hooked end 11 for engaging the rail 8. The ends 11 of the clamps are made to fit loosely over the edges of the

rails

8 and 9 so that the clamps can be readily attached to and removed from the rails. The horizontal part of .the member 10 has a slot 17 therein, with a bolt l3, w hich, with the washer 18 and nut 19, serves to hold the clamp securely on the side rail 8. The vertical part 12 of the other clamp has therein a slot 17, similar to the slot 17 in the part 10, and has a bolt 13 seated in said slot. The head 16 of the bolt and washer 14 are drawn up by the nut 15 to bear against the vertical part of the rail 9, and serve as an adjustable clamping device or attaching member for holding said clamp in rigid position on the rail. The slots 17 permit these clamping devices to be adjusted to rails formed of different widths of angle iron.

The heads 16 of the bolts 13 each acts as and is a clamp jaw, coacting with the'parts 12 and 10 respectively. It will be understood that one of the clamp jaws of each pair, namely, the

nut

15 or 19, has both a vertical and a horizontal adjustment relatively to its companion jaw which is the head 16 in one case or the slotted part of member 10 in the other.

The depending vertical part of the arm 10 prevents the clamp from being shifted from side to side of the rail 9. One of the arms of the clamp 10 is provided with perforated ears 3 to which the tubular part 4 of the other arm of said clamp is pivotally connected by means of the bolt 5 having thereon the nut 20.

The clamps 21 are attached to the side rail 22 of the spring in similar manner as the clamps 10 are attached to the side rail 9. The lower part or projection 23 of the clamp 21, however, does not have a depending part extending along the outside of the side rail 24. This part 23 serves merely as a stop for holding the spring the proper distance above the rail 24 to support said spring in the horizontal position. The bolt 25 has a head 16 and an arm 26 secured to its outer end. This arm serves in connection with the movable finger 27 for clamping the bed clothes and mattress upon the spring frame. Each of the

end rails

28 and 29 of the bed spring frame has attached thereto a clamp 30 to which is pivotally secured the arm 31 of the spiral spring 32. ,The arm 33 of said spring is pivotally secured to one of the end rails 34 of the bedstead by means of the clamp 35.

The operation of the device is as follows: The bed spring frame will be attached to the side rail 8 by means of the clamps formed of the

members

10 and 12. The springs 32 are of suitable strength to hold the bed-spring frame in the position shown in Fig. 1, but not of suflicient strength to prevent the bedspring frame from resting in the horizontal position after it has been pulled down to said position. When in such horizontal position, the springs 32 will move to the position indicated by the dotted lines 37. Said springs, when in such position, with their

arms

31 and 33 lying along each other, will offer less resistance than when said arms are in alinement and will therefore aid in permitting the spring frame to rest in the horizontal position. The leverage of the sprin frame when in the horizontal position will a so aid in counteracting the effect of the springs 32. l/Vhen in a vertically disposed position, said sprin frame is supported mainly on its hinged en at the rail 8, and therefore re uires but slight support to prevent it from 'ilropping to the horizontal position. The spring-arm 33 has its lower end bent to form a sto 36 which bears against the under surface 0 the rail 34 and limits the downward movement of the arm 33 to a position above the floor indicated by the dotted lines 37.

, The mattress and bed clothes may be readily clamped by pushing the finger 27 down upon the rod 26, the finger being held down by leverage and friction on the rod 26. The functionand operation of the finger 27 is the same as that of similar devices used heretofore at the lower ends of folding beds. The rod 26 and finger 27 will be used to clamp the bed clothes only when it is desired to raise the spring to the position shown in Fig. 1. At other times, said rod will be turned down to a horizontal position along the side-rail 22.

What I claim as my invention and desire to secure by Letters Patent is:
