SPRING-BED.

Specification of Letters Patent.

Patented Mar. 2, 1915.

Application filed April 10, 1914, Serial No. 831,085.

T all whom it may concern Be it known that I, THOMAS JACKSON R1DowAY,.a citizen of the United States, residing at Wichita, in the county of Sedgwick and State of Kansas, have invented a new and useful Spring-Bed, of which the following is a specification.

The structure forming the subject matter of this application is a spring bed and one object of the invention is to provide a novel form of connecting member or hook, which, projecting from one spring, cooperates with another spring and with a guy wire in a novel manner.

Another object of the invention is to improve the guy wire construction so as to permit the guy wire. to cooperate with one spring and with the connecting member or hook.

It is within the scope of the invention to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

With the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in they details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawing :-Figure 1 shows in fragmental top plan, a spring bed constructed in accordance with the present invention, parts being broken away; Fig. 2 is a transverse section on the line 22 of Fig. 1; Fig. 3 is a section on the line 33 of Fig. 1 Fig. 4 is a section on the line 1 1 of Fig. 1; Fig. 5 is a perspective view illustrating one of the bottom ties; Fig. 6 is a perspective view illustrating one of the upper ties; Figs. 7 and 8 are perspective views illustrating modifications of that structure which is depicted in Fig. 5.

The spring bed embodying the present invention preferably includes a top frame 1 across which extend cross ties 2. In the are formed, as will be Fig. 6. One side 1 of the bend 3 is longer than the other side 5 thereof, thereby forming in the cross tie 2, a relatively high part 6 and a lower part 7.

The invention includes any desired numcross ties 2 bends 3 understood best from ber of springs, the springs being denoted by the numerals 8 and 9. These springs are substantially alike in construction. The upper convolution of the spring 8 is indicated by the reference character 10 and in this convolution 10 is formed an upright, rectangular loop 11, shown most clearly in Fig. the loop 11 passing around the next lower convolution 12 of the spring and passing around one such convolution only. The loop 11 is prolonged to form an arm 14, terminated in a hook 15 engaged around the top frame 1.

In the convolution 10 of the spring, oppositeto the loop 11 is formed, as shown best in Fig. 2, a depending bend 16.

The upper convolution of the spring 9 is indicated at 17 and is formed with a loop 18 resembling the loop 11 and engaging a single convolution of the spring, as before. The loop 18 is prolonged to form an arm 19. The arm 19 passes as indicated at 20 in Fig. 2, between the convolution 10 of the spring 8 and the lower portion 7 of the cross tie 2. The arm 19 as shown in Fig. 2 abuts laterally against the upstanding bend 3 in the cross tie 2 and against the depending bend 16 in the convolution 10 of the spring 8, these bends being disposed in close relation to each other as will be understood when Fig. 1 is compared with Fig. 2. The arm 19 terminates in an angularly disposed finger 21. This finger 21 is disposed at right angles to the arm 19 and is parallel to the planes of the bends 16 and 3 and lies against the bend 3 of the guy wire 2. The finger 21 is bent to form an extension 22 lying at right angles to the finger 21 and parallel to the arm 19. The extension 22 passes beneath the bend 3 of the cross tie 2 and above the depending bend 16 of the convolution 10 of the spring 8. The extension 22 is terminally bent to form an underlying tip 23 disposed at an angle of 52 to the extension 22. The tip 23 extends beneath the bend 16 of the convolution 10 of the spring and engages the same.

A bottom frame 24 is provided, opposed portions of the bottom frame 24 being united by transverse ties 25 and longitudinal ties 26, these ties being equipped with interlocked bends 27. The bends 27 may be rectangular as shown in Fig. 5, they may be curved as shown at 28 in Fig. 7, or they may be of V-shape as shown at 29 in Fig. 8. The lower convolution 30 of each spring pames beneath the tie 26 and lies above the tie 25, the said convolution terminating in an upstanding finger 31 engaged around the tie 26.

The arm 19, the finger 21 and the extension 22 constitute what, for convenience, may be denominated a square-nosed hook, since the extension 22 is parallel to the arm 19 and since the finger 21 lies at right angles to the parts. This feature is of importance and, so far as I am advised to the state of the art forms one of the distinguishing characteristics of the invention. Since the finger 21 lies at right angles to the arm 19, a firm and secure bearing for the upper convolution 10 of the spring 8 is afforded, and yet this convolution is not pinched or bound. Since the finger 21 lies at right angles to the arm 19, the finger 21 bears smoothly and evenly against the upstanding bend 3 of the cross tie 2. Because the extension 22 lies at right angles to the finger 21, the extension passes fairly between the depending bend 3 of the convolution l0 and the upstanding bend of the cross tie 7. As will be understood readily, the angularly disposed, underlying tip 23 forms an important interlocking element.

Attention is directed to the fact that one side 4 of the bend 3 in the cross tie 2 is shorter than the other side 5 of the bend, thus causing one part 7 of the cross tie to be lower than the other part 6. By this construction, noting the point at which the reference character 20 is applied in Fig. 2, it will be observed that opportunity is afforded for the arm 19 to pass between the cross tie and the upper convolution 10 of the spring without distorting or tilting the spring.

The square knot or loop formed at 11 and at 18 is easily and accurately made and the foregoing holds true with respect to the bend 27 formed in the bottom cross ties.

Having thus described the invention, what claim as new is 1. In a spring bed, a cross tie having an upstanding bend the side portions of which are of unequal length, thereby to form a high portion and a lower portion in the cross tie; a spring, the upper convolution of Which passes across the bend in the cross tie; and a connecting element located between the said convolution of the spring and the lower portion of the cross tie, thereby to prevent a tilting of said upper convolution of the spring and to permit the same to set level, the connecting element terminating in a hook which passes between the bend of the tie and said convolution of the spring.

2. In a spring bed, a cross tie having an upstanding bend, the side portions of which are of unequal length, thereby to form a high portion and a lower portion in the cross tie; a spring, the upper convolution of which is providedwith a depending bend which overlaps the bend in the cross tie; and a connecting element located between said convolution of the spring and the lower portion of the cross tie thereby to prevent a tilting of said convolution of the spring and to permit the same to set level in abutment with both bends, the connecting element terminating in a hook which passes between the bends.

8. In a spring bed, a cross tie having a bend; a spring one convolution of which is provided with a bend which overlaps the bend of the cross tie; and a connecting element passing between said convolution and the cross tie to one side of the bends, the connecting element including a hook which passes between the bends, the hook terminating in an underlying tip which extends beneath the bend of the spring and engages the same.

4:. In a spring bed, a cross tie having a bend; a spring, one convolution of which is provided with a bend overlapped upon the bend of the cross tie; and a connecting element comprising a body which extends between the cross tie and the said convolution of the spring, the body being bent at right angles to form a straight finger parallel to both bends, the finger being bent at right angles to form a straight extension parallel to the body and passing between the bends at right angles to the planes defined by the bends.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
