- CARPET-STRETCHER.

SPECIFICATION forming part of Letters Patent No. 273,130, dated February 27, 1883.

Application filed January 2, 1883.

To all whom it may concern:

Be it known that I, GEORGE ll/IULLIGAN, of Taunton, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Carpet Stretchers; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being bad to the accompan yin gdrawings, forming part of this specification, in which- Figure 1 is a side elevation of my invention, showing the manner of using it; Fig. 2, a top plan view of the same. Fig. 3 isa bottom plan view of the toothed head; Fig. 4, a sectional view taken on the line 00 m of Fig. 3.

Similar letters of reference in' the several figures denote the same parts.

My invention consists of an improved carpet-stretcher constructed and adapted for operation substantially as I will now proceed to describe.

Referring to the accompanying drawings, A B represent two arms, jointed together by a cross-bolt, a, upon which works a set-nut, b. To the arm A is connected a cross piece or head, (3, suitable brace-rods, c, extendingfrom the arm to the head near its ends, as shown, forstrengthenin g the connection between the parts. Upon the under face of the head 0 is secured a plate, D, preferably 'of metal, having two or more openings, d, through which project groups of sharp forwardly-inclined prongs or teeth 0, connected preferably to a flexible backing, E, interposed between the head and the plate 1), as clearly shown in Fig. 4. The outer end of the arm B is perforated for the passage of a bolt,f, and from this bolt depend links F, which are perforated at their lower ends for the passage of a bolt, G.

H represents a bar having a series of holes, h, extending laterally through it at intervals throughout its entire length, and carrying at one end an end piece, I. The cross-bolt G is adapted to pass through the links F and through one of the several holes h, and to form, in connection with the links, an adjustable pivotal connection between the arm B and the bar H.

In putting down a carpet one edge of the carpet is tacked near the base-board at one side of the room, and the carpet is spread out (No model.)

and drawn with the hand, as near as may be, to the opposite side of the room. The end piece, I, of the bar H of the stretcher is then placed against the base-board at the tacked edge of the carpet, and the cross-bolt G is adjusted through the links and through one of the holes h of the bar H, with the head 0 bearing the prongs or teeth engaged with the carpet near its edge at the opposite side of the room. The operator then be'ars down upon the joint of the arms A B until the arms are sufficiently depressed and extended to cause the toothed head to stretch the carpet and bring its edge to the opposite base-board, and when this is accomplished he tightens up the nut I), thus clamping the arms AB securely in their adjusted position, and enabling him, with hammer and tacks, to secure the edge of the can pet. This operation is repeated until the carpet is secured all around.

The adjust-ability of the cross-bolt G in the various holes of the bar H gives the stretcher a wide range of action and enables it to be employed effectively in rooms of'varyin'g lengths, while the connection of the arms A B with each other and with the bar H through the adjustable pivoted link F renders thewhole stantially as described.

2. The combination, with the head, of the plate secured to its under side, and having the opening and theforwardly-inclined prongs or teeth, and its flexible backing between the plate and the head. substantially as described.

GEORGE MULLIGAN.
