GEORGE C. LOCKLIN, OF KENOSI-IA, VISCONSIN.
SPECIFICATION forming part of Letters Patent No. 540,838, dated June 11, 1895. I l lpplication filed April 30, 1894. Serial No, 509,440. (No modeLl .To all tcl/tom it may concern:
Be it known that I, GEORGE C. LocKLIN, of
. Kenosha, in the county of Kenosha and State of Wisconsin, have invented a new and useful Improvement in Fastenings for Spiral-Spring Bed-Bottoms and Mechanism for Securing Such Fastenings to the Springs, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.
My invention has relation to improvements in fastenings for spiral spring bed bottoms, and to the mechanism for securing such fastenings to the springs.
'The object is to provide an improved construction for preventing tilting or sidewise motion of the'bed spring, which shall combine economy,'simplicity, and efciency to the my improved device properly applied thereto.`
Fig. 2 is a detail plan view of the device, showing thelugs before being bent over. Fig.
3 is an inverted plan'of Fig. 2. Fig. 4 is an elevation of Fig. 2. Fig. 5 is a plan view of a fragment of a spring, showingthe cross-bars and my improved device in proper adjusted position, the lugs being shown as bent over the wire. Fig. 6 is a transverse section of Fig. 5 on the line 6 6. Fig. 7 is a transverse section of Fig. 5 on the line 7 7 thereof. Fig.
' 8 is a plan View of a table upon which the bending the lugs.
spring bed-bottom is placed for the proper adjustment thereto of the fastening illustrated in Figs. 2 and 3. Fig. 9 is an end View of the table. Fig. 10 is a section through one of the adjustable bars of the table.' Fig. 1l is a detail elevation of one of the pins of the table. Fig. 12 is a plan view of the upper end of said pin. Fig. 13 is a detail elevation of a tool for Fig. 14 is a bottom plan view of the same, and Fig. 15 is a section of a fragment of the lower end of the tool. l
Like numerals of reference denote like parts throughout the several views.
ksides of the frame, are parallel wires 18, 18.
Each of theselwires is provided with a series of lateral V-shaped bends 19. These, as will be clearly seen, extend under the upper coils of the wires. The hooked ends of short connectingwires 20, 20 connect the upper coils of adjacent springs', said hooked ends being bent under the V shaped bends 19, and then over the upper coils of the springs. Other hooks 2l connect the springs to the sides of the frame 16. The base frame (not shown) is, of course, connected up to the lower coils of the springs in exactly the same manner as that described with reference to the upper frame. About centrally between the upper and lower border frames is a smaller rectangular frame 22. Connecting opposite sides of this frame are parallel wires 23, 23, which run through the centers of the springs, while connecting the two other opposite sides ofthe frameare similar wires 24:, 2l, which also run through the centers of the springs, but beneath the wires 23.
The parts above described are common in spring bed bottoms, and hence form no part of my invention, excepting only so far as they cooperate or combine with the other mechanism about to be described.
My improved center fastening illustrated in detail in Figs. 2, 3 and 4 consists, prefer-Y ably, of a ringor annulus 25, provided on its upper side with projecting lugs 26, 26, ar ranged in sets of two. Depending from the under side of the ring or `annulus are other lugs 27.
Figs. 5, 6 and 7 show more clearly thel manner in which the ring is secured within the center of a spring. It will be seen that it is arranged within the spring beneath the lower wire 2l, opposite sets of the lugs 26 receiving said wire therebetween, while the other opposite lugs 26 receive therebetween the upper wire 23. The next step is the bending of the ICO ` apart.
lugs, so as to securely hold the wires, and then simultaneously with the bending of the lugs the crimping of the Wires. The mechanism for accomplishing this is clearly illustrated on Sheet 2 of the drawings, which mechanism will now be fully explained.
The numeral 2S indicates a supporting table, upon which is arranged between end pieces 29, 29, a series of longitudinal beams 30. These beams are provided with a series of recesses or openings 3i, which are adapted to receive thereduced or tenoned ends of pins 32. The upper ends of these pins are provided with a series of edge notches 33, which extend a slight distance down the sides of the pin. Each longitudinal beam is advisably provided with thirteen of these pins, arranged equi-distances apart, and as there are nine beams in connection with thetable,this makes a total of one hundred and seventeen pins, which number exactly corresponds to the number of springs employed ordinarily in a wide bed. In narrower beds, one or more rows of springs are of course dispensed with. The end pieces 2), 29 of the table are slotted longitudinally, as indicated at 34, and as clearly shown in Fig. 9 of the drawings. Through these slots pass bolts 35. Each bolt enters the end of alongitudinal beam 30,aud extends across a vertical opening 36 of the beam, carrying on its threaded portion within the opening a nut 37. rlhe head 3S of the bolt bears against the outer side of the end piece. The opening 36 permits access to be obtained to the nut 37, whereby, when the nut is turned up tightly on the bolt, the beam is, of course, held firmly against the end piece. The object of this construction is to permit the several longitudinal beams to be adjusted closer together or farther apart, in order to accommodate spring bed bottoms in which the springs are arranged at varying distances In order to accomplish the adjustment, it is obvious that all that is necessary to be done is simply to loosen the nuts 37, which will, of course, permit the beams to be moved the desired distance laterally.
Upon the upper ends of the pins 32 the fastening rings 25 are placed, the under lugs 27 thereof fitting in the notches 33 of the pins to prevent turning of the rings. The spring bed bottom is now placed upon the table in such manner that each one of the pins 32 will extend upintoaspringabouttothe centerof said spring, the sets of lugs 26, 26, respectively, being made to embrace the wires 23 and 24 of the intermediate rectangular frame 22. The lugs 26 are bent over so as to firmly lock the wires 23 and 24 by means of a tool 39 (Fig. 13). The lower end of this tool is provided with intersecting V-shaped grooves 40 and 41, the latter having secured therein pins 42, 42, which project slightly below the end of the tool and are provided with grooved ends. The next step, after arranging the spring bed bottom on the table in the manner just described, is to bring the tool 39 into operation for the purpose of bending over the lugs 26. This tool, therefore, is passed vertically through the center of a spring until the lugs 2G are received in the V-shaped grooves, said grooves being wide enough to admit the endsof thelugstherein. Atthesametimethe upper Wire 23 is received in the grooved ends of the pins 42, 42. If, now, a forcible blowis given to the upper end of the tool, it is obvious that the lugs will be bent so as to close over the Wires 23 and 24, and at the same time the pins 42, 42 will bend the top Wire 23 down at the points 43, 43, (see Fig. (i) While the under wire 24 by reason of the elfectof the blow on the upper wire will be bent centrally, as indicated at 44 in Fig. 7.
It is evident that "a spring bed bottom in which the springs are stiiiened by the fasteningr devices such as herein shown and described, possesses superior advantages, the devices being of such character as to bc readily applied in the novel manner herein shown and set forth, and, when properly adjusted to the springs, preventing all sidewise or tilting motion of the springs, thereby providing a spring bed bottom which is practically level throughout; or, in other Words, one in which the springs are maintained as nearly as possible fiush with each other, and the border wires or frames standing straight at the corners.
I do not wish to be understood as confining myself to the exact construction of details, inasmuch as it is apparent that changes may be made without departing from the spirit and scope of my invention. For instance, it is not absolutely necessary that the fastening devices 25 be of circular or annular form, inasmuch as the same may be constructed either square, rectangular, or in any other desirable shape, so long as the sets of lugs thereof are so arranged and disposed as to rcceive therebetween the cross Wires 23 and 24.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-
l. The combination, of a spring bed bottom provided with a frame and with cross wires, springs through the coils of which the cross Wires pass, said cross wires intersecting each other within the circumference ofthe springs, a fastening device for each spring arranged intermediate the ends of the spring, said device provided with locking means arranged' for each cross Wire, and engaging said cross wires, respectively, at points distant from the intersection of the Wires, substantially as set forth.
2. The combination, of a spring bed bottom, provided with a frame and With cross wires, springs through the coils of which the cross wires pass, said cross Wires intersecting each other within the circumference of the springs,-
a fastening device for each spring, arranged intermediate the ends of the spring, said device provided with sets of' upwardly extending lugs, arranged for each cross wire, and
IOO
engaging and bent over said cross Wires, respectively, at points distant from the intersection of the Wires, substantially as set forth.
3. The combination, of a spring bed bottom provided with a frame and With cross Wires, springs through the coils of which the cross 4wires pass, said cross wires intersecting each other within the circumference of the springs, and crimped at said points of intersection, a fasteningdevice for each spring arranged intermediate the ends of the springs, said device provided with locking means arranged for each cross wire, and engaging said cross Wires, respectively, at points distant from the intersection of the wires, set forth.
4. The combination, of aspring bed bottom provided with a frame and with cross Wires, springs through the coils of which the cross wires pass, said cross VWires intersecting each other Within the circumference of the springs, a fastening device for each spring, arranged intermediate the yends of a spring, said de- Vice provided upon one side with locking means arranged for each cross wire and engaging said cross Wires, respectively, at points distant from the 'intersection of thewires, and upon the opposite side with depending lugs, substantially as set forth.
. 5. The combination of a base pin, a fastening device adapted to be supported thereon,
substantially asY lsaid device provided With sets of upwardly therein, and to bend said lugs inwardly, when l' force is applied to the tool, substantially as set forth. I
6. The combination, with a basepin adapted to support the article to be bent, of a bending tool provided on its end with intersecting grooves, one of said grooves having pins projecting therefrom, substantially asset forth.
7. The combination, of a table having longitudinally slotted end pieces, longitudinal beams arranged between said end pieces, said beams provided with upwardly 'extending' pins, and also provided near opposite ends with openings, bolts passing through the longitudinal slots of the end pieces, and engaging the longitudinal beams, said bolts passing into the openings of the longitudinal beams, and nuts turning upon the threaded ends of the bolts within the openings, substantially as set forth.
