GUSTAF A. TORNKVIST, OF MINNEAPOLIS, MINNESOTA.
IBED-SPRIN G FRAME.
To all whom it may concern:
Be it known that I, Gus'rar A. TORNKVTST,
Minneapolis, in the county of Hennepin and State of Minnesota, have lnvente'd certain new and useful Improvements in Bed-Spring Frames; and I do hereby declare the follow- .ing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention has for its object to provide an improved bedspring especially adapted for use in connection with iron bedsteads; and to this end it consists of the novel devices and combinations of devices hereinafterdescribed and defined in the claim.
In the accompanying drawings which illustrate the invention, like characters indicatelike parts throughout the severalviews.
teferring to the drawings, Figure 1 is a view in side elevation, with {some parts broken away, showing myimproved bed spring connected to the head and foot frames of an iron bedstead. Fig. 2 is a plan view of the parts shown in Fig. 1, some parts being removed and some being broken away. Fig. 3 is a section taken on the line ga of Fig. 2. Fig. 4 is a detail partly in side elevation and partly in section on the line :12 m ofFig. 3; and Fig. 5 is a. detail in section on the line .70 of Fig. 2. I
The numeral 1 indicates the head frame and the numeral 2 the foot frame of an iron bedstead of standard or any suitable construction, the same, as shown, being mounted on casters 3. These head and foot frames 1 land 2, as is customary, are formed with tubular columns to which are rigidly secured, preferably by being cast thereon, coupling brackets 4 having intheir inwardly projecting ends the customary lock grooves 5. The sides of the spring frame are preferably made of angle iron bars 6, to the ends of which are rigidly secured, preferably by being c ast thereon, quite heavy coupling brackets 7 that are provided with vertically tapered heads 8 adapted to fit the lock grooves 5 of the coupling brackets 4 in substantially the usual way. The side bars of the swing frame also serve as the side bars to t e bedstead; and, for the attachment of the woven spring body 9, the coupling brackets 7 are formed with upwardly and forwardly curved anchoringlugs 10 that re Specification of Letters Patent.

These rods or pipes ,11 serve as Windlass shafts, by means of which the spring body may be tightened.
To hold the pipes or shafts 11 against rotation, anchoring pins 13. are driven through radial perforations 14 of the said pipes and through suitable seats formed in the anchoring lugs 10 and in the bodies of the coupling The spring body 9, atits brackets 7 Preferably, the pipes are pro- To facilitate turning of the pipes or shafts 11 to tighten the spring, metal plugs 15 having angular wrench seats are preferably secured in the ends of the said shafts, as best shown in Fig. 4.
With the device described, it is a .Very easy matter, at any time, to tighten up the spring body and thereby take out the sag thereof due tostretching incident to use. At the same time, the spring frame itself affords means for connecting the head and foot frames of the bedstead and thereby eliminates the necessity of independent rails for the bedstead.
What I claim is z" The combination with side rails and couplingbrackets secured to the ends thereof, said coupling" brackets having curved anchoring lugs, of tubular shafts rotatively held by said lugs, plugs having angular wrench seats secured to the ends of the tubular shafts, pins driven through seats in the'anchoring lugs, through diametrically alined perforations in the tubular shafts and plugs and into seats .in thecoupling brackets, and a woven wire spring-secured at its ends'to said shafts, substantially as described.
In testimony whereof I affix my signature in presence of two witnesses.
