ROCKING-CHAIR HOLDER.

Specification of Letters Patent.

Patented Mar. 13, 1917.

Application filed July 21, 1916. Serial No. 110,552.

To all whom it may concern:

Be it known that I, AVERILL M. BENNETT, a citizen of the United States, residing at Fromberg, in the county of Carbon, State of Montana, have invented a new and useful Rocking-Chair Holder; and I do hereby declare the following 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.

This invention relates to an improved rocking chair holder, and one of the objects of the invention is to provide a holder of this kind, to prevent the chair from creeping or walking when in a rocking motion, hereby preventing the chair. from contacting with other pieces of furniture that are in the room.

Another object of the invention is to provide a standard having anchoring means to hold the standard on the floor, and a sleeve yieldable on the standard, in combination with pressure arms carried by the rocker to increase pressure on the yieldable sleeve, to increase the suction action of the anchoring means of the standard, when the rocker is in motion, thereby preventing the rocker from creeping or walking.

A further object of the invention is to provide means carried by the pressure arms to engage the floor, to actuate the pressure arms while the chair is in motion, to increase the pressure on said yieldably mounted sleeve, thereby preventing displacement of the standard.

In practical fields, the details of construction may necessitate alterations falling within the scope of what is claimed.

The invention comprises further features and combination of parts, as hereinafter set forth, shown in the drawings, and claimed.

In the drawings Figure 1 is a view in side elevation of a rocking chair, showing the improved holder for preventing creeping or walking of the chair as applied.

Fig. 2 is a sectional view on line 2-2 of Fig. 1.

Fig. 3 is a view in front elevation of the chair, showing the creeping preventing device, as applied.

Fig. 4: is a sectional view on line 4% of Fig. 1.

Fig. 5 is a sectional view on line 55 of Fig. l.

Fig. 6 is an enlarged detail sectional view on line 66 of Fig. 1.

Fig. 7 isa detail perspective view of a bearing block for the pressure arms, for holding said pressure arms to one of the rockers of the chair in the manner shown in the drawings.

Fig. 8 is a detail perspective View of one of the pressure arms.

Referring more especially to the drawings, 1 designates a metallic plate having a depression 2 in its under surface, to receive a rubber suction or vacuum cup 3, which cup anchors or adheres itself on the floor or the rub thereof by creating a vacuum between the cup and the floor, thereby anchoring the plate 1 in position. Rising upwardly from the plate 1 is a re duced standard 4, and mounted thereon so that the standard will engage the bearings 5 and 6 is a sleeve 7, which is rectangular in cross section. The sleeve 7 between the upper and lower bearings 5 and 6 is hollowed out from one side, for the reception of the coil spring 8, which is mounted upon the standard, betw en the upper part of the sleeve and the pin 9, which extends transversely of said standard, which spring acts to raise the sleeve to hold the lower part of the sleeve normally nearer the pin 9. A rod 10 extends through the lower part of the wall of the sleeve, and is secured therein by the nuts 11 and the lock nut 12. This rod 10 merges into a single volute helix spring 13, which terminates in an end portion 14 axial with the body of the rod 10. A hearing block 15 is secured by means of screws 16 to one of the rockers of the chair, and in bearings of the block 15 the rocking rods 17 are mounted. The outer portions of the rods 17 terminate in right angle extending arms 18, which incline from each other and toward the floor, so that their curved extremities will bear on the floor. The inner portions of the rods 17 terminate in angular portions 19 having parts 20, which bear upon the laterally extending lugs 21 of the sleeve 7. The end portion let of the rod 10 beyond said spring 13 passes through the bearing block and has a nut 22 threaded upon its end, thereby connecting the rod 10 to therocker, by means of the bearing block, which in turn is secured by said screws to the rocker. When the rocking chairis in motion, there is a torsional strain upon the spring 13, thereby assisting in imparting motion. to the chair. Furthermore, upon each movement of the rocker, the rocker creeps or walks a trifle, tending to crush or depress the spring 13 axially, but at the end of each movement of the rocker, the spring 13 expands and restores the rocker to its normal position. These actions successively repeat as the rocker is in motion. The pressure arms which engage the lugs 21 depress the sleeve 7 downwardly against the action of the spring 8, thereby applying yieldable pressure upon the plate 1, sutficiently to press the rubber cup 3 against the floor or the carpet thereon, so as to cause a vacuum between the rubber cup and the floor, thereby anchoring the standard in position. As the rocker rocks rearwardly, one of the arms '20 of one of the rocking rods 17 bears additionally upon the sleeve thereby increasing the pressure on the cup, to increase its hold to the floor. lVhen the rocker rocks in the opposite direction, or forwardly, the other arm 20 depresses the sleeve against the action of its spring, thereby increasing the hold of the cup to the floor. These actions likewise are successively repeated.

The invention having been set forth, What is claimed as new and useful is 1. In a creeping or walking preventing device for rockers, the combination of a standard having a vacuum anchoring connection with the floor and a sleeve yieldably mounted upon the standard, of a yieldable connection between the SlQG"G and the rocking rail of the rocker, and means mounted in hearings on the rail and designed to cooperate between the floor, the rail, and the sleeve, for depressing the sleeve successively during the rocking movement of the rocker.

2. In a creeping or walking preventing device for rockers, the combination of a standard having a vacuum anchor connection with the floor and a sleeve yieldably mounted on the standard provided with laterally extended lugs of a yieldable connection between one of the rocking rails of the rocker and said sleeve, a pair of rocking rods mounted inbearings on the rail, each rod having a right angle extending arm engaging the floor at one end, and an offset arm at the other end engaging one of the lugs, to successively depress the sleeve, as the rocker is in motion.

3. In a creeping preventing device for rocking chairs, the combination of a standard having a vacuum anchoring connection with the floor and a sleeve yieldably mounted upon the standard, of a rod connected to one side of the sleeve adjacent its lower portion and merging near its other end into a single volute helix spring terminating in an end portion axial with the body of the rod and connected to one of the rockers of the chair, a pair of rocking rods mounted in bearings on one of the rockers, each rocking rod having a right angle extending arm at one end to engage the floor and an oil' set arm at the other end, said sleeve having laterally extending lugs to be engaged by the off set arms of both rocking rods, whereby the sleeve may be successively depressed as the chair is in motion.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

AVERILL M. BENNETT.
