FOOT AND LEG REST.

WHAE'Z.

To all whom it may concern:

Be it known that I, JOHN A. GAERTNER, a citizen of the United States, and a resident of Boston, in the county of Suffolk and State of Massachusetts, have made certain new and useful Improvements in Foot and Leg Rests, of which the following is a specification.

My invention relates to improvements in combined foot and leg rests, and it consists in the constructions, combinations and arrangements herein described and claimed.

My invention is an improvement on the device disclosed in my prior Patent No. 918433, of April 13, 1909. These improvements will be disclosed in the following specification and will be set forth particularly in the appended claim.

My invention is illustrated in the accompanying drawings forming part of this invention in which similar reference characters denote like parts in the several views and in which Figure 1 is a side view showing one embodiment of my invention. Fig. 2 is a detail view showing the means for attaching the leg rest to the chair. Fig.3 is a detail view showing the means for suspending the end of the leg rest. Fig. 1 is a section along .the line t 1- of Fig. 3. Fig. 5 is a perspective view of the leg rest. Fig. 6 is a perspective view of the base. Fig. 7 shows a clamp which constitutes part of a modified means for securing the leg rest to the chair. Fig. 8 is a section through the chair and leg rest showing the means of applying the clamp. Fig. 9 is a perspective view showing the detail means for pivotally suspending the end of the leg rest, and Fig. 10 shows the parts illustrated in Fig. 8 as assembled.

In carrying out my invention I provide a base 1 of any suitable shape but preferably that shown in Fig. 6. To this base are secured the hollow uprights 2 and 3. In the upper ends of the uprights are slots 2 and 3 respectively for the reception of a cross member 4. The tops of the supports 2 and 3 are covered with the caps 2 and 3 respectively. To the ends of the member 41 are attached the spiral springs 2 and 3. The opposite ends of these springs are continued down the supports 2 and 3 and. terminate in threaded ends upon which is secured a wing nut 5 which may be tightened so as to exert a tension against the spring. The

wing nut is disposed in a recess in the base 1 as clearly shown in Fig. 4, and bears against a stationary member 6.

Secured to the rod 1 at its central portion is a vertically extending rod 7 provided with a weight at its lower end and bearing at its upper end the L-shaped arms 9 and 10. The latter are pivotally connected with the leg rest 11 in the following manner: It will be noted that the leg rest 11 has an upwardly extending portion 11 to which is secured a laterally extending portion 11 On the sides of the latter are secured the plates 12, see Fig. 9, which are provided with short screw studs 12 arranged to receive a threaded nipple 13, having an opening 14 for the reception of the end of the rods 9 and 10. The plates 12 are secured to the part 11 by means of nails or screws and the nipple 13 is pushed over the ends of the rods. The end of the leg rest is then placed between the rods and the nipples are secured to the threaded lugs 12% thereby providing the end of the leg rest with a pivoted bearing which permits the removal of the leg rest at will.

The preferred means for fastening the leg rest to a chair, is that illustrated in Fig. 2. In this case, I make use of a strip 15 which is provided with openings 15 at each end for the reception of straps 16. The bar 15 is also provided with the screw-eyes 15 which are arranged in alinement. The leg rest 11 is also provided with the screw-eyes 11, which, when the leg rest is placed close to the bar 15, are in alinement with the screw-eyes 15. A rod or pin 17 see Fig. 1, may then be run through the alined screweyes to pivotally connect the leg rest with the rod. The latter may then be strapped to a spindle 18 of the chair 19 in the manner shown in Fig. 1.

The means for preventing the movement of the weight 8 is shown in Fig. 6. This consists of a locking member 21 which is provided with a slot 22 and a knob 23 for manipulating it. It will be noted that the base is provided with a longitudinal groove 24: which is situated mid-way between the supports 2 and 3, and within which the lower end of the weight swings. Now by holding the weight 8 in its lowermost position, the locking member 21 may be moved by the handle 23 so as to confine the end of the weight in the slot 22 on one side, and in the slot 25 in a slide plate 26 which is carried by the base 1.

From the foregoing description of the various parts of the device the operation thereof may be readily understood. The leg rest may be attached to a chair in the manner already described and is preferably provided with the cushion 27. If the locking members 21 and 26 are in the position shown in Fig. 6 the occupant of the chair may be rocked to and fro and the rod 7 bearing the weight 8 will oscillate on its pivots, while the part 11 of the leg rest will oscillate on the pivots formed by the ends of the arms 9 and 10. The weight 8 and the springs 2 and 3 tend to hold the chair and the leg rest in the position shown in Fig. 1, but if it is desired to put a greater tension on the spring, the wing nuts 5 may be tightened so as to draw down on the spring and thus adjust the tension. In case the occupant of the chair does not wish to rock, the locking members 21 and 26 may be moved so as to lock the weight in its lowered position.

In Figs. 7 and 8 I have shown a modified means of attaching the leg rest 11 to the chair 19. This consists of a clamp 28 provided with resilient material 29 on its inner face and having openings 28 for the reception of screw-eyes 80. YVith this form of the device the clamp 28 is secured to the seat 19 as shown in Fig. 8 on the outer corners thereof. The screw-eyes of the leg rest lie in line with the screw-eyes 30 and are held by means of the rod 17 as before.

It will be seen that I have provided a leg rest which may be readily attached to a chair and which is pivoted at both ends to permit a relative movement of the rest, chair and oscillating support.

I am aware that other forms of the device based upon the same general idea, might be made but I consider as my own all the modifications that clearly fall within the spirit and scope of the invention.

I claim:

In a foot and leg rest, a grooved base, a pair of metal uprights carried thereby, an oscillating support pivoted on said uprights, a leg support pivotally connected with said oscillating support at one end, a chair having a pivotal connection with said leg support at the other end, the lower end of said oscillating support being adapted to enter the slot in said base, and a strip provided with a slot arranged to be moved over the groove in said base for locking the oscillating sup-port in a stationary position.
