Application lei september 24, 1920. Serial No. 412,594,

and which is adjustable to fit chairs of dif# :ferent sizes.

TWith these and other objects in View, the invention consists in certain novel features of construction as hereinafter shown and described, and then specifically pointed out in 'the claims, and in the drawings illustrative of the preferred embodiment of the in-A vention.

ln the accompanying drawing:

Figure l represents a perspective view of a portion of a chair equipped with `one of the rockers constituting this invention.

Fig. 2 is a plan view of the rocker de tached with parts broken out for convenience in illustration.

Fig. 3 is a transverse section taken on the line 33 of Fig. l, and,

Fig. 4 is a detail perspective view of the le connector and rocker reinforce.

n the embodiment illustrated, the rocker 1 constituting this invention is composed of a longitudinally curved piece of channel shaped metal open at its top, the sides 2 of which are disposed parallel and are provided Vat corresponding points with inturned flanges 3, said flanges beingarranged at the points where the legs L and L of a chair are to be connected. These legs L and L are provided on their opposed side faces with transversely extending grooves 4 to receive the flanges 3 when the rocker is connected with the legs. The side members 2 of the rocker are also provided with aplurality of longitudinally spaced bolt holes 5 arranged near the upper edges of the flanges, those in one fiange registering with those in the other and designed to receive clamping bolts 6 which pass through the flanges and through apertures E) in the side members 8 of inverted Ushaped connectors '7'. These connectors T have cutout portions 10 in the connecting web thereof for the reception of the chair legs, the distance between the side members 8 of said connector being slightly less than that between the side members 2 `of the rocker so that these connectors will snugly fit in the rocker between said side members.

In the use of this rocker the chair legs are first inserted through the connectors 7 and said connectors positioned in the rocker and moved longitudinally under the flanges 3, the latter entering the grooves 4 in the legs as is shown clearly in Fig. l. After the legs with the connectors attached have been so positioned the bolts 6 are passed through the apertures 5 in the rocker and those 9 in the connector being positioned one on one side of the leg and one on the other. The nuts on the bolts are then screwed inward and clampingly connect the rocker to the chair legs avoiding all possible danger of them becoming separated.

The apertures 9, two of which are formed in each leg or side member 8 of the connec tor 7, are arranged a distance apart to correspond to the distance between the alternate apertures 5 in the rocker members 2 so that the connectors may be adjusted longitudinally relatively to the rockers to adapt the rockers to be used on chairs having legs arranged different distances apart.

These rockers 1 may be composed of any suitable metal, preferably sheet iron or steel or they may be made df aluminum an owing to their peculiar construction and the means for connecting them to the chair legs they are rendered practically unbreakable and they cannot be detached without removing the bolts, the nuts on the bolts being preferably secured by cotter pins or other wise.

`The members 7 perform the double function of connectors for the legs and reinforces forthe rocker at thepoints of connection with the leg, the ianges 3 also assisting in strengthening the rocker at this point as well as for engaging the grooves of the legs to retain the rocker against vertical movement on the legs.

The preferred embodiment of the invention is disclosed in the drawings and set forth in the specification, but it will be understood that any modifications Within the scope of the claims may be made in the construction Without departing from the principle of the invention or sacrificing` any o'I' its advantages.

What is claimed is: Y

l. Ahollow metal chair rocker open at' its top, the sides thereof being provided at corresponding points with inturned. flanges to enter slots in the chair legs With which the rocker is to be connected, leg connectors mounted between the sides of the rocker at the flanged portions thereof, and means for elampingly securing said connectors engaged with said legs.

2. A hollow metal chair rocker open at its top, inverted U-shaped connectors mounted between the sides of the rocker and having a cutout portion in each Web thereof to receive achair leg to be connected to the rocker, and bolts passing throughthe legs of said connector and the side Walls of the rocker for clampingly uniting them.

3. hollow metal chair rocker open at its top, the sides thereof being provided at corresponding points with inturned flanges to enter the slots in the chair legs to be connected with the rocker, said sides having a plurality of longitudinally spaced alined bolt holes near the upper edges thereof belon' the flanges, inverted U-shaped leg connectors adapted to be positioned in the rocker at the flanged portions thereof and having apertures to register with the bolt holes in the rocker, the Webs of said connectors being cut out for the passage there through of the legs to which the rocher is to be secured, and bolts passing through the rocker and the connectors on opposite sides of each leg.

In testimony whereof, I ailix my ,signature hereto.
