AUXILIARY SPRING ATTACHMENT non srarne BED Bo'rroM's;

Application-filed November 1 7, 1922. Serial No. 601,627.

To all whom it may, concern I Be it known that I, SAMUEL RosnfIBLooM,

a citizen of Lithuania, residing at Lowell, in

the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Auxiliary Spring Attachments for Spring Bed Bottoms, of

which the following is a specification My invention relatesto auxiliary spring attachments for spring bedbottoms. It may be used with metal beds to which woven wire bed bottoms are directly attached or to any type of beds wherein the main springs are removable from the bed frame.

I It may also be used with the type of spring bed bottoms wherein helical springs extend from head to foot.

lVhere these types of bed springs are used there is a tendency to sag inthe middle where the weight comes, and this tendency increases with use as the springs stretch and become weaker.

My attachment is entirely separate from the bed and main springs, and is intended to be sold separately and is of such construct-ion that the purchaser can readily put it in place in such position that it will best counteract thesagging of the main springs. It can also be adjusted to some extent vertically and is also arranged, so that when anyone sits on the side of the bed, auxiliary springs allow. of giving thus relieving the helical springs. I I

These auxiliary springs help to equalize any sudden shock, and help to absorb it without disturbing the other part'of the bed. By their use two persons of different I l l holes 40,. bolts 44 and nuts 45,'these dogs weights can sleep in the same bed without inconveniencing each other In the drawings, Figure 1 is a plan view of a metal bedstead of -well known construction with the head board and foot board cut oif and mattress removed toexpose removable springs of a well known .type where the bod of the spring is made of crossed wires wit tension springs at each end.

Fig. 2 is a bottom View of my auxiliary spring attachment removed from the bed,

Fig; 4 is a side elevation showing part of a bed'fraine with my device'in position. Fig, 5 isa detail sectional elevation showing one of the dogs and supports on a larger scale than shown in Fig. 3. i i

F ig. 6 is a detail sectional elevation show- 16,16, 16, side rails 10, 11, and the usual cross bars 14 and 15 at the head and foot.

' The main spring bed bottom is represented by B and'includes sidebars 20' and 21,

ing the adjusting and nut for one of the shown as of the common tubular type with the connecting head bar 22 and foot bar 23. The woven fabric 246s of a well known type and 1s elastically connected with thehead bar and foot bar by tension springs 25. The

bed andsprin s are of a well known type;

My device, indicated generally by C, includes'parallel spacing bars 30 and31 havmg a guide rod hole 32 extending vertically througheach bar near each end and having an adjusting slot 35 also located near the end of each bar. These bars are shown as being preferably formed of metal angle irons to secure rigidity.

Bars 30 and 31 are supported at each end a supporting D having bolt holes 40, 40 through which pass "adjusting bolts 44:, 44 on the end of which are winged nuts 15, as shown in Figfd. By means of slot 35 can be slid in and outas shownby the dotted lines in Fig. 5 forgconv enience'in adjusting in position. I i k Each d'og ha's a lower jaw 41 and an upper jaw 42 which latter preferably terminates the bed A in case the main springsB are removable. Inany exentthejaws 41 and in a nose 43 whi'ch, when in position, extends over andre'sts upon aside rail 10 or 11 of 42 fit around .a side ' bar 20 or 21 and hold my attachment in the desired position.

'I may use in connection with "each dog a setscrw v416'whichpasses "through one of the 'jaws and bears again'st a barQO or 21 wherebymy device can be shipped with the I main springs and held firmly in position against sliding. I

it represents a rigid bottom frame comprising side members 50, 51 and front and loackmembers 52 and 55, connected at the corners by braces 54 to make it rigid.

Through this frame are rod holes 55, 55, 55, y

55 Which register with the guide rod holes 32, 32, 32, 32 in the bars 30 and 31.

Extending down through each rod hole 55 is an adjustable guide rod 81 on which are clamping nuts 82 and 83, thence down through a hole 32, each such rod being adjustably held in position extending down from frame E by adjusting nuts 82 and 83 and. 'by winged nut 84L.

Preferably, surrounding each rod is an auxiliary compression spring 80. These springs 80 tend to keep my device up against the bed bottom but it can readily be lowered against these springs or raised by screwing up or down nut 84.

F represents the top frame which may be rigid or, preferably, semi-rigid. It is shown as formed by means of a relatively heavy rectangular wire 60, between thesides ofwhich extend the lighter wires 61 to hold it from distorting. The helical springs 70, 70 are carried by thebottom frame E and support the top frame F, being attached to wires and 61 in such manner that they will not tear the mattress.

Preferably, they are so positioned and arranged as to form ahollow rectangle whereby a. substantial space of perhaps six to twelve inches is left between the front and back rows 71, 72, while the side rows are filled in by springs 73, 74.

The effect of this arrangement is to stiffen up the sides of the bed but to leave a relatively soft but firm section between 71 and 72.

I prefer to bend up the .wire 60 of top frame F at each side, as shown in Figs. 4

and 5, to holdat 90 and 91 mattress M in position, and to use connecting wires, such as 92, to maintain the rigidity.

To put in place, the dogs D on one side may be slid back-and the device pushed up from under'the bed, or, slid in between fabric B and a bar 20 or 21, and the dogs slid out to engage said bars where they can be clamped in position by nuts 45.

In Figs. 7, I show how a modification of my structure can be used as with a bed in which the side rails, such as 10 and 11, and side bars. such as 20 and 21, are combined as in a tubular side bar such as S.

In this case, I make the dogs, such as 105,.

- and horizontal weblOl with a rod hole 102.

The dog 105 has only an upper jaw and simply rests on bar S.

.E represents the bottom frame with a member 53 the same as in the other constlllCtlOIl, and with a rod hole 55 through which passes a rod 106 which also passes through rod hole 102. j

As shown, there are two clamping nuts 82 and 83 to hold it rigidly to frame E and two clamping nuts 105 and 10 1 to hold it rigidly to the spacing bar P.

I claim: 7
