Y the sleeve is held in placeq The U-clamp 22 embodies a U-frame the

side members

26 and 27 of which are of different lengths. The U-frame is adapted to be set astride the end rail 9 of the bed frame from the under side thereof with the short side member 26 of the frame extending beneath the springs 10 and with the elongated frame member 27 projecting upwardly at the end of the spring frame, as particularly shown in Fig. 2.

The frame member 26 carries a clamping screw 2S which is threaded in the frame member 26 and is adapted to bear against the inner face of the frame member 9 to clamp the U-frame in position on the spring frame. rlhe elongated sidefmember 27 of the frame is formed with spaced superposed

openings

29 and 30 through either of which the threaded stem 21 extends according to the height desired to space the shaft 21 from the lower portion of the U-frame, and whereby the device is adapted to be applied and operated with spring frames of various heights.

The shaft 21 is fitted with a crank 31 which is engaged with the end of the shaft 21 projecting through a frame member 27 whereby the shaft may be readily rotated. It will now be seen that the tensioning members 2O may be disposed at any desired point throughout the Width of the bed springs and that any desired number of the tensioning devices may be employed, as occasion may require. In some instances, it may only be necessary to employ but one of the tensioning devices, and in others it may be necessary to employ two or more, but in any event, by reason of the tensioning devices being engaged with the spring-engaging clamp at various points throughout the width of the spring, the tensioning devices may be disposed so as to exert a` pull at points where it is desired to take up the slack in the bed spring.

A modified form' of the mounting of the tensioning members on the spring clamp 12 is shown in Fig. 5, and embodies a sleeve 32 which is slidably mounted on the upper bar 13 and has upstanding lugs 33 formed with an internally threaded opening 3d in which the threaded'shaft 21 is screwed; the sleeve 32 being adapted. tobe moved longitudinally of the bar 13 into any desired posh tion. l Means are provided whereby the spring clamp 12 may be temporarily secured to the side members 7 and 3 of the spring frame, as where it is desired after placing the spring 10 under tension, to remove, replace or change the position of the tensioning devices 20. Y

This means is here shown in Fig. l as comprising a U-bolt 35 which is adapted to be placed astride the side frame 7 or 8 from the under side thereof, and to have its end portions inserted through the openings 17 and 18 of the bars 13 and 14 adjacent oposite sides of the rails 7 or 8 to receive

wing nuts

36 and 37.

The' portion of the U-bolt 35 extending beneath the rail 7 or 8 is formed with teeth 38 adapted to engage the side rail so as to hold the U-bolt against sliding movement on the rail.

ln the use of the device, the spring engaging clamp is secured to the spring 10 in the manner described and the tensioning shafts 21 are each rotated successively to draw the bars forward, thus stretching the spring. By turning one shaft 21 a greater amount than the other' shafts, portions of the spring may be stretched more than other portions. Also by omitting some of the bolts the saine effect may be obtained.

When the spring has been stretched the desired amount the spring clamps may ie secured to the side rails of the spring frame to hold the spring in its stretched position, and the shafts 21 may be removed to facilitate re-securing the spring permanently in its stretched condition upon the frame. To do this the cleat may be removed, and the loose end of the spring brought forward by the bars is cut away and the spring re-secured by the cleat. When the U-clamps and bars are removed the spring is then in a fully stretched condition, all sagging portions having been drawn up.

lllhereas, have shown and described a specific construction and arrangement oi parts l do not wish to be confined thereto but may use such constructions and combinations of the salient features of the invention as come within the scope of the appended claims.
