CARPET-STRETCVHER'ND JACK.

` SPECIFICATION forming part Of Letters Patent NO. 536,148, dated March 19, 189.5.

Application filed January 6, 1894. Serial No. 495,928. (No model.)

.To all whom it may concern:

Be it known that I, HosMnR FARRINGTON JACKSON, of Tyrone, in the county of Blair and State of Pennsylvania, have invented a new and Improved Carpet-Stretcher and Jack, of which the following is a full, clear, and exact description.

My invention relates to a tool adapted for household use, and it has for its object to provide a tool which will combine within itself a -jack adapted for lifting stoves or other heavy articles of furniture, and which may also be applied as a carpet stretcher and may be further used as a tack hammer and a claw for withdrawing tacks, nails, or like fastening devices from ythe objects into which they may be driven.

.vso

A furthery object of. the invention is to pro'- vide a tool ofthe characterabove described which will be simple, durable and economic in its construction, and capable of being readily comprehended and effectually usedby any person of ordinary intelligence.

The invention consists in the novel construction' and combination' of v the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similarfigures andletters of reference indicate corresponding parts in all the views. i

Figure 1 is a perspective view of the tool, illustrating its application as a carpet stretcher. Fig. 2 is a perspective view of the tool,

illustrating its application as a jack; and Fig.4

yor provided upon what may be termed its outeror top surface with a series ot `ratchet teeth 11, while upon the side opposite that in whichk the channel 10 is located a series of rack teeth 12 is produced, The body bar is further provided at its top" or one end with a claw 12, the said claw being projected from the side or face having the ratchet teeth 11, the projection being in direction ofthe opposite face of the bodyrbar, as shown in-both Figs. 1 and 2, while at thejun ction of the body bar with its claw upon that face in which the ratchet teeth 11 are located a knob or hammer head 13, is formed.

A carriage B, is held to slide upon the body bar, which carriage is constructed to carry a pinion 14, the said pinion being adapted to engage with the teeth 12 ot the body bar, and the pinion 'has `secured to it a socket 17, adapted to be turned through the medium of a crank arm of any approved construction introduced into the socket, which crank arm, if desired, may constitute an integral portion of the socket. 'The carriage is provided with two collars 15 and 16, adapted to slide upon the body bar, and the body portion, about centrally between thecollars in which the said pinion 14 is journaled. The carriage is further provided with a pawl'18, which pawl is so pivoted and constructed that it ,normally gravitates in direction of the ratchet teeth 11, and engages with said teeth as is particularly shown in Fig. 2.

One of the sleeves, the inner one 15, is pro- 4The stretching arm 19, is provided with a seriesof pins 20, which pins whelr the said stretching arm is located at right angles to the body bar, as shown in Fig. 1, incline in direction of the spur 12a on the said body bar. The crank arm 2l, which is preferably employed to manipulate the pinion 14, is that which is shown in detail in Fig. 3, which crank arm is provided with a head 22, which may be employed. as a hammer head, and a tongue 23, which is adapted to enter the socket 17, the tongue being capable likewise of manipulation for driving a tack or like fastening device, while at the extremity of the crank arm Ico at which the head 22 and tongue 23 are located a claw 24, is also formed, of a bifurcated character, the members of the claw being convexed upon one face and concaved upon the other, in order that they may be utilized for withdrawing tacks, nails or like objects, the head 22 of the crank arm serving as a fulcrum.

When the tool is to be used as a carpet stretcher, for example, the claw 12a of the body bar, is introduced into the floor adjacent to the base board, while the stretching arm 19, is placed transversely or at right angles to the body bar, and the crank arm 21 when introduced into the socket 17 may be turned, and by so turning said crank arm the carriage B maybe made to travel in direction of the spur,

and since the teeth 20 of the stretching arm will enter the carpet, said arm will carry the carpet with it in direction of the spur, the pawl 1S serving to prevent the carriage losing whatever ground it may have acquired in a forwardly direction by the manipulation of the crank arm, while by pressing the free end of the pawl it will be carried out of engagement with the rack teeth l1, and may be readily carried in any direction along the body bar; whereas, when the tool is to be employed as a jack, the body bar is placed in a vertical position with its claw 12a uppermost, and the material to be raised is made to rest upon the extension of the upper sleeve 15 of the carriage, and by manipulating the socket of the carriage the pinion will travel upon the teeth 12 of the body bar, and will serve to raise or lower the object that may be supported upon the sleeve 15 of the carriage.

When a hammer is required for driving tacks for example, or a tool is desired for withdrawing a tack, the crank arm 21, by being removed from its socket may be utilized for such purposes, the claw 211 serving to Withdraw tacks, while the head 22, or even the tongue 23, may be used for driving the tack.

It is obvious that this device while exceedingly simple and economic in its construction, may be successfully employed for the purposes intended, by any person capable of un derstanding the use of even the simplest tool.

Then matting is to be stretched the cross bar 19 is placed parallel with the body bar A, beneath said bar, and the teeth 20 are made to engage with the selvage edge or seam of the matting only.

I-Iaving thus described my invention, I claim as new and desire to secu re by Letters Patent- 1. A tool of the character described com' prising a body bar provided with a spur at one end and having rack teeth and ratchet teeth arranged upon surfaces at right angles to each other, a carriage fitted to slide upon said body har, a pawl carried by the carriage and adapted for engagement with the ratchet teeth, a pinion located in the carriage and engaging with the rack teeth, an extension for lifting purposes located on the side ot' said carriage opposite to that carrying the pinion means for revolving said pinion and a stretching arm provided with pins and formed upon the lines of a compound curve, the said arm being pivoted at the junction ot' the curved portions upon the surface of the carriage, as and for the purpose specified.

2. A tool of the character described, comprising a body bar provided with a spul' at one end and having rack teeth and ratchet teeth arranged upon surfaces at right angles to each other, a carriage fitted to slide upon said body bar, a pawl carried bythe carriage and adapted for engagement with the ratchet teeth, a pinion journaled in the carriage and engaging with the rack teeth, a crank arm whereby the pinion is revolved, an extension for lifting purposes located near one end of the carriage on the side opposite to that car rying the pinion, and a stretching arm provided with pins and pivoted near its center upon the surface of the carriage, as and for the purpose specified.
