FLOOR-LAYING JACK.

Application filed April 24, 1319.

To a ZZ whom it may concern e it known that I, iViLLmM A. NEVILLE, a citizen of the United States, residin at Kewanee, in the county of Henry and State of Illinois, have invented certain new and useful Improvements in Floor-Laying Jacks and I do 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 jacks.

One object of the invention is to provide an exceedingly convenientand very effective device for pushing floor-boards into place and holding them while being nailed to the sills or sub-floor.

A further object is to provide a device of this character in which a hand of an operator maybe assisted by a foot in a oughly practical, convenient and comfortable manner, and in which the foot entirely relieves the hand after the floor-board is pushed into position, so that both hands may be employed in the nailing operation.

Other objects and advantages may become apparent to persons who read the following details of description in connection with the accompanying drawings, in which;

Figure 1 is a side elevation of the device, a portion of the handle bar being broken off, the device being shown in a position attained during the operation of pressing the board into its final position on the sill or sub-floor.

Fig. 2 is a top plan view of the part of the device disclosed in Fig. 1, the pusher being shown in dotted lines, as well as in full lines, thereby disclosing the device in its open and folded positions.

ig. 3 is a view somewhat similar to Fig. 1 except that the device is shown in longitudinal vertical section.

Fig. 4; is a side elevation illustrating the device in the position attained after the floor-board has been entirely pushed to its final position.

eferring to these drawings in detail, in which similar reference characters correspond with similar parts throughout the several views, the d vice comprises a pusher 5, a sill-engaging member 6, a hand-lever 7 a bolt or pivot 8 and a rivet or securing memher 9.

The pusher or member 5 is str p of m a wh ch s bent invention relates to floor-laying formed of a at points spaced Specification of Letters Patent.

from its middle portion, as indicated at 10, and its end portions 11 are apertured at 12 to receive the pivot 8, and the end portions 11 converging from the bent portion 10 to the apertures through which the pivot 8 extends.

The sill-engaging member 6 is formed of a strip of metal which is bent adjacent its middle portion, as indicated at 13, and its ends terminate in sill-engaging elements or points 14 which are turned laterally of the main body of the bar or sill-engaging men ber 6. Ends of the sill-engaging member preferably diverge from the rivet 9, as indicated in Fig. 2, and the portion between the apertures 15 which receive the rivet 9) and the bent portions 13 provide a space whose width is substantially equal throughout its length, and in this space is disposed a branch 16 of the hand-lever 7 The rear end portion of the branch 16 is apertured at 17 to receive the pivot 8, and the member 7 is also apertured at 18 to receive the rivet 9. It will be seen, therefore, that the hand-lever 7 is readily united with the sillengaging member 6 while the

members

6 and 7 are pivotally united with the pusher 5. Branch 1.9 of the hand-lever constitutes a handle-bar for actuating the member 6, and coacts with for actuating the pusher 5. In view of the foregoing description, it

. will be seen that ample space is provided behind the bar 19 for permitting the foot of the operator to be placed over the pivot 8, thereby obtaining a most effective and con venient position for the foot in actuating the device and holding it in its effective position while the hands are otherwise employed.

In employing the term sill-engaging in connection with this device, the broadest definition of the word sill is intended, that is, it is intended to mean any horizontal supporting structure. Furthermore, it is not intended to limit this device to the use herein ascribed thereto.

lVhat I claim is:

1. In a floor-laying jack, a floor-board pusher. and a rigid structure including a sill engaging member having a sill-engaging element at one end and a pivot at its other end portion. said pusher being movably secured to said sill-engaging member by said pivot, said rigid structure also including a handlebar which extends from the middle portion of the sill-engaging member substantially at right angles to the common plane of said pivot and sill-engaging element, whereby the foot of an operator can conveniently be pressed down on the pivotal connection to aid the hands of the operator in the laying of floor-boards, substantially as shown.

2. A floor-laying jack comprising a pusher, a bifuracted sill-engaging member, a handlebar, and a pivot, said pusher and sill-engaging members being pivotally connected together by said pivot, said pusher being formed of a strip, oi'metal bent at points spaced from its middle and having its end port-ions converging toward said pivot, said sill-engaging member being formed of a strip of metal bent at points adjacent to its middle and having its ends'ten minating in laterally turned sill-engaging points, said bent middle portion being disposed between the converging end portions of said pusher at the pivotal connection of the pusher and sill-engaging member, said handle-bar having one end portion disposed between and Secured: to the. furcations of said sill-engaging member.

3. In a lioor-laying jack, a bifurcated sillengaging member comprising sill-engagingpoints on its'furcations and'having an aperture therethrough adjacent to the junction of its furcations, an L-shaped handlever having an aperture through one of its branches, a bifurcated? pusher having an aperture in each 0i its'furcations, the said sill-engaging member having its said junction disposed between the furcations of said pusher, a pivot extending through said apertures and thereby pivotally uniting said pusher with said sill-engaging member and also uniting the latter with said hand-lever, and. means co-acting with said pivot for holding said hand-lever and sill-engaging member in rigid relation to one another.

4;. A ack comprising a pusher, a sill-en turned sill-engaging points, said bent mid dle portion being disposed. betwe n the converging end portions of said pusher at the pivotal connection of the pusher and sillengaging member.

In testimony whereof I have hereunto set my hand.
