MATTHEW B. SPAOKMAN, OF DU BOIS, PENNSYLVANIA, ASSIGNOR OF ONE- HALF TO LOGAN U. TRUXAL, OF SAME PLACE.

CARPET-STRETCHER.

SPECIFICATION forming part of Letters Patent No- 363.0 3, dat M y 1887- Application fied October 26, [886.

T aZZ whom, it may concern:

Be it known that I, MATTHEW B. Srnerc MAN, of Du Bois, in the county of Clearfield and State of Pennsylvania, have invented cer- 5 tain Improvements in CarpetStretchers, of

which the following is a specification.

This invention relates to that class of carpetstretchers in which claws or spurs for engaging the carpet are carried upon a cross-head [0 adapted to be moved longitudinally with re lation to a frame-bar by means of an oscillat-' ing lever.

The object of the invention is to construct a carpet-stretcher which is simple and effective in operation, can be readily adjusted for different-sized rooms, and can be constructed at small cost.

To this end the invention consists in particulars of construction and combinations,

which will be fully described in the following specification and claimed in the clauses at the close thereof. 7

In the drawings, Figure 1 is a perspective view of my improved carpet stretcher. Fig. .25 2 is a longitudinal section thereof.

Referring to the drawings, the frame-bar A is provided at its under side with a longitudinal slot, a, forming a guide or way, in which the stretcher-bar B is adapted to slide. This stretcher-bar I3 is provided upon its upper face with a rack, 12, and upon one end with a crosshead, B, to which is secured a plate, 1), pro vided upon its edge with spurs or claws to engage the fibenof the carpet. This plate I) is provided with vertical slots If, in order that it may be adjusted to bring the points of the spurs or teeth more or less below the under surface of the cross-head B, to more perfectly adapt it for use upon different carpets, and is secured to the cross-head by means of screws, as shown, whereby it may be secured tightly in place after adjustment.

To the forward end of the frame-bar A is pivoted a lever, A, and to this lever is pivoted 4 5 a pawl, a, to engage the rack of the stretcherbarB and urge it forward; and to retain the stretcher-bar inits step-by-step adjustment I pivot a gravitating pawl, a in the end of the frame-ha r A,to engage a tooth of the rack while Serial No. 217,255). (No model.)

the lever A is being oscillated backward to engage its pawl with another toot-h of the rack.

The frame-bar and stretcher-bar may be of such relative size as to fit the stretcher for applying the carpet to a room of ordinary size,

(it being understood that the rear end of the U frame-bar is to rest against the base board at one side of the room,) and to adapt my stretcher for operating upon carpet in larger rooms I provide an extension-frame, 0, adapted to be coupled to the rear end of the frame-bar A. This extensiouframe C may also be provided with a groove or way, 0, to receive an e: tension-bar, B fitted with a rack, 11, to recelve a gravitating pawl, 0, whereby the brace-head d of the extension-bar may be adjusted with relation to said extension-frame. The extension-frame is provided at the sides with latches E, provided with spurs 0, adapted to be driven into the floor, to assist in steadying said extension-frame; or, in the event of the room or compartment being of an extent outside of the limits of adjustment of my stretcher, these spurs may be driven into the floor at the center of the room, or away from the baseboard, to hold the rear end of the stretcher while the front end is operated to stretch the carpet at the sides of the room.

As a means for connecting the extens1onframe 0 with the frame A, I have secured upon the rear end of said stretcher-frame a loop to receive a tongue projecting from the forward end of the extension-frame; but it will be understood that I do not limit myself strictly to these or other small details of construction.

By the means here shown and described I am enabled to adjust this carpet-stretcher to operate in rooms which are, strictly speaklng, beyond the range of the adjustment of the device.

In rooms of limited capacity it will of course be understood that the extension-frame and its adjuncts will not be used, the rear end of the frame A, in this instance, abutting against the base-board at one side of the room while the stretcher-bar is moved forward. The stretcher possesses the further advantage that thetoothed plate (1 may be adj usted vertically with relation to the cross-head to which it is attached,

to fit it for use upon carpets of different texture, and this adjustable feature also admits of the teeth being sharpened and lengthened should they become worn.

I am aware that carpetstretchers have been variously constructed with ratchet-bars mounted to slide in frames or bodies, and combined with levers and pawls to advance and hold them, and also that the frames have been constructed for longitudinal expansion and contraction, and to such features, broadly considered, I lay no claim. It will be observed that in my structure the body is divided into two separable sections, and that it is provided at the rear end, not only with the extensionbar B, for use in rooms of limited width, but also with the retaining-dogs E, by which it may be held in position when the room is of a width greater than the length of the implement. In halls or rooms of very narrow width the section 0 and its appurtenances may be removed and the body-section A used alone in connection with its extension-bar Owing to the above features my apparatus is capable of a great range of adjustment, and is adapted for use under all circumstances likelyto arise in practice.

Having thus described my invention, what I claim is-- 1. In a carpet-stretcher, the combinationof the frame or body, the' ratchet-bar B, retaining-pawl a and the actuating lever and paw], all mounted on one end of the body, and the extension-bar B, its retaining-pawl c, and the dogs or catches E, all located at the opposite end of the body.

2. In combination with the body-section A, provided with the ratchet-bar, the retainingpawl, and the lever and pawl to effect the advance of the ratchet-bar, the removable section 0, provided with dogs or catches E, whereby the body may be retained in position.

In testimony whereof I hereunto set my hand, this 17th day of August, 1886, in the presence of two attesting witnesses.
