PATENT OFFICE. I

OF LEBANON, MISSOURI, ASSIG-NOR OF ONE-HALF TO FRANK D. GUILD, OF SAME PLACE.

CARPET-STRETCHER.

SPECIFICATION forming part of Letters Patent No. 431,488, dated July 1, 1890.

Application filed March 10,1890. Serial No. 3%,352- (No model.)

To all whom it may concern:

Be it known that I, CHARLES SACK, a citizen of the United States, residing atLebanon, in the county of Laclede and State of Missouri, have invented certain new and useful Improvements in Carpet-Stretchers; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters of reference marked thereon.

This invention relates to certain new and useful improvements in carpet-stretchers;

and it has for, its object, among others, to provideap'iimproved device of this character, which shall be simple,-d urable, and efficient.

The novelty in the present instance resides in the peculiarities of construction and the combinations, arrangement, and adaptation of parts, all as more fully hereinafter described, shown in the drawings, and then particularly pointed out in the appended claim.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, and in which- Figure l is a side elevation of a carpetstretcher constructed in accordance with my invention. Fig. 2 is a top plan of the same with parts broken away to better show the construction. Fig. 3 is a vertical cross-section.

Like letters of reference indicate like parts throughout the several views.

Referring now to the details of the drawin gs by letter, A designates two bars arranged parallel to each other and provided along their adjacent edges with a groove a, as shown in Figs. 2 and 3. I

B is a head or cross piece securely affixed to the bars A and further braced by the diagonal brace-arms b, as shown in Figs. 1 and 2. Upon the under side of this crosshead is a plurality of sharp-pointed pins or analogous devices 0, inclined, as shown in Fig. 1, for the purpose of engaging and holding the carpet when the device is in use. The opposite ends of the bars A are connected by the metallic cross-bar O, secured to the upper faces thereof in any suitable manner.

D is a bar, preferably somewhatwider than the bars A and provided upon its edges with ribs cl, which work in the grooves of the said bars A, as shown in Figs.2and 3. end of this central bar D is provided with a metallic sleeve or thimble E, as shown in Figs. 1 and 2, and adapted to receive abar F, as indicated by dotted lines in said figures, the said bar in use being of a length to reach. to the opposite side of the room, the resistance being the opposite wall. This bar F may be in a single piece or of several pieces,'so as to be extensible. The central bar D is provided with two upright bearings f, provided with lugs e at their forward ends, and in these bearings is j ournaled the cross-shaft G, upon the ends of which is the cog-wheel g, which meshes with the parallel racks H 011 the bars A, the said racks being set into the said bars, as shown in Fig. 3, and secured in any suitable manner. Fast on the shaft G, centrally thereon, is a larger ratchet-wheel I.

J is a lever sleeved on the shaft G and formed with lugs h,between which is pivoted the dog or pawl 11, as shown in Fig.1, the said pawl having a handle j, beneath which is arranged a fiat spring K, as shown in said Fig. 1, and acting to at all times keep the pawl in engagement with the ratchet-wheel.

Between the lugs e of the bearings f is pivoted the retaining-catch L, adapted also to engage the ratchet-wheel and prevent back movement of the parts, as will be readily understood.

The operation is simple and apparent. The extension is fitted in the thimble E and reaches to the opposite side of the room for ordinary-sized rooms, allowing about eight inches between the cross-head and the wall. The pins will engage the carpet, and by operating the lever the head and side bars are propelled forward and the carpet is drawn toward the wall the required amount, when it can be tacked in place. After the carpet is secured the head is then thrown back, first disengaging the retaining-catch. By holding the lever and ratchet-pawl and pushing on the cross-head it is again ready for use.

A carpet-stretcher constructed as above described will always be ready for use, and will be found to have sufficient power to stretch heavy carpets without breaking under severe Strains.

The outer What I claim as new is p In a carpet-stretcher, the combination, with the outer parallel bars and the cross-head thereon, of the central movable bar, the bear- 5 ings thereon, the shaft journaled in said bearings, the cog-Wheels on the ends of the shaft, the ratchet-Wheel arranged centrally on the shaft, the lever sleeved on the shaft and formed with ears, the pawl pivoted between I0 said ears and provided with a handle, the

' spring on the lever beneath the said handle,
