, PATENTBD SEPT. s, 1904. M. E. SHINN. CARPET STRETGHER. APPLICATION FILED BEI'TQZS, 1903.
UNITED STATES Patented September 6, 1904..
PATENT OFFICE.
CARPET-STRETCHER.
SPECIFICATION forming` part of Letters Patent No."769,328, dated September 6, 1904.
Application filed September 23, 1903. Serial No. 174,350. (No model.) l
yTo all whom, t Ivm/,y concern:
Be it known that I, MARTIN E. SHINN, aciti- Zen of the United States, residing at Chicago,
Cook county, Illinois, have invented certain new and useful Improvements in` :Carpet- Stretchers, of which the following is a specication.
My invention is an improvement in carpetstretchers, and relates specially to the improved means for giving movement to the carpet-'holding part so as to stretch the same uniformly and perfectly.
The invention is shown in the accompanying drawings, in Which- Figure 1 is a side elevation of the invention.
Fig. 2 is an elevation from the front of the device.
Fig. 3 is a sectional View. Fig. tis a detail. Fig. 5 is a View of a modification, and Fig. 6 shows a second modification.
In the gures I have shown a barA, with a vtoothed or turned-over end a, adapted to enbracket B, which has swiveled to it an elon-l gated bar C, carrying a series of projecting teeth or pins c, adapted to engage with the carpet. These pins or points extend through the bar C at an angle, as shown atFig. l. The bar C is swiveled to the bracket B, as shown in the detail view Fig. 4., and 'the' sectional View Fig. 3, so that the bar may be moved on itspivot a. to get the proper anglein case this is required to be varied. The points c engage the carpet, and the stretching action is secured by moving the bracket B upon the bar A. This is accomplished by a screw or worml D, which is mounted upon a spindle d, extending from the upper part of the bracket B above the position of the bar A. 'The Worm D has a handle e, whilethe teeth of the Worm engage the teeth of the rack-bar A. As the handle c is turned the Worm engaging the teeth on the bar moves the bracket B, gradually stretching the carpet. by reason of the engagement therewith of the points c.
This baris toothed on its upper` In Fig. 5 I 'have shown a modification in 'which instead of the swiveled construction shown in Fig. l I have shown the bracket B, with a projecting point Z2', and one or more of these may be provided integral with the bracket. In other respects the construction and operation are the same. 4
In Fig. 6 I have shown a further modification', and in this I provide an eccentric clamp, with a serrated face, and'thus through the medium vof a plate CZ the material to be stretched is clamped to the lower face of the bracket B, and a stretching action'is secured by the action before described.
It will be seen that .by the peculiar shape of the handle it does not in use project forward `of the screw or Worm D, but is in rear thereof, so that it does not offer an obstruction to the near approach of the stretcher to the wall, and thus the' carpet can be drawn much closer to thewall than in any other construction with which I am familiar. The stretching is Very gradual and may be stopped or interrupted at any point.
` What I claim isl. A carpet-stretching device comprising a rack-bar, a bracket, carpet-engaging means carried by the bracket, a rearwardly-extending projection on said bracket, a worm journaled on said projection and engaging said rack-bar, and a handle for rotating said worm, said handle being.at all times during its rotation in the rear of saidprojection, substantiallyv as described. y
2. A carpet-stretching device comprising a rack-bar, a bracket, carpet-engaging means carried thereby, a projection on said bracket, a worm journaled on said projection at an angle to said rack-bar, and means for rotating said worm, said rotating means being at all' times in the rear of said worm, substantially as described.
In testimony whereofI afX my signature in presence of two witnesses.
MARTIN E. sI'IINN.
