Description
N. PETERS. PHOTO LTMOGR NrTED STATES PATENT OEErcE.
NOBLE HILL, OF OA'ION, NEW YORK.
IMPROVED CARPET-STRETCHEFL Specification forming part of Letters Patent No. 46,357, dated Febnrary 14, 1865.
To all whom it may concern:
Be it known that I, N. HILL, of Caton, in
' the county of Steuben and State of New York,
following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part ot' this specification, in which I Figure l is a side sectional elevation of my invention; Fig. 2, a plan View ofthe same.
Similar letters of reference indicate like parts.
The object of this improvement is to facilitate the even spreading and stretching of carpets, mattings, and all kinds offloor, deck, or roof coverings.
A A' are tlat blocks havin g their lower surfaces provided with a series of points or spurs, a.
B B' are the stretching-bars,each composed of two parts, b c, said parts being capable ot moving or sliding one over the other, but held together by bands C, attached to their alternate extremities.
D are adjusting-pins passing through adjusting-holes d in the bars B, for the purpose ot' preventing the bars from moving'upon each other after they have been set or adj usted.
The lower extremities ot' the bars B are notched or stepped, so as to iit into or engage with corresponding` notches or steps made in the upper surfaces of the spur-blocks A, as shown in the drawings, the several steps or notches being so made as to permit a free vertical movement ofthe bars B B'. The upper extremities ofthe bars B are so shaped as to form a species ot socket-joint, the extremity of one bar being made concave, and the other convex so that when the two extremities thus made are put together they form a joint which the form of an arch. One of the spur-blocks A being now pressed so that it cannot slip over the iioor, downward pressure is applied to the bars B B' so as to straighten them. Thereupon the other block A will move in direction of the arrow, and carry with it the carpet, (shown in red,) which will be stretched with a force equal to the downward. pressure applied to the bars B B'. If no force is applied tohold either of the blocks A A' down upon the tloor, it is obvious that by the downward movement'of the bars B B' both blocks A A' will be moved, and the carpet will be equally stretched in two directions.
The arrangement of the exterior bars permits the adjustment ofthe instrument for use in apartments and upon carpets of variable sizes. The simplicity ot' my improvement, the convenience of its adjustment, the cheapness ot' its construction, and its effectiveness for the purposes described will be obvious.
The bars B B', instead of being made in two parts, may be made of single pieces or bars, but I prefer to construct the bars in two parts, as shown, as it permits a greater range ot' adjustment than could be obtained by the use of the single bars. By having the sides of the bars provided` with graduatinglines, as shown, the bars B B' may be conveniently adjusted to equal lengths, or their lengths may be varied as circumstances require. The several bars and blocks being independent and separable from each may be quickly packed for removal or transportation.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- A The combination of the duplicate extensionvbars B B', provided with bands C O C U and locking-pins D D, with the spur-block A A', whereby I secure the required range and efiiciency, as well as compactness for transportation, substantially as described.
NOBLE' HILL.
Witnesses I GEO. W. PRATT, J oHN C. HAY'r.
