PATERNAYAN CARPET AND RUG STRETCHER 3 Sheets-Sheet 3 Filed June 26. 1934 TORNE INVENTO| ,E/r/y flfafemaya/z 1 BY WITNESSES m a link 25 in which the hook 26 is mounted, said hook being identical to that shown in Figs. 5 and 6. A chain, cable or other flexible connection 2'7 is provided and connected by a suitable pin 28 to the hook 26. As shown in Fig. 1 the chain or connecting device 27 is formed with legs 27 and 27", each leg being wrapped around the drum 29. The drum 29 has its ends rotatably mounted in standards 30, which standards are rigidly secured to the upstanding flanges 31,said flangesbei'ng part of the angle irons 32 which form a frame when taken with the angle iron 20 and the front plate 34. A seat 35 is mounted at one end of the frame so that the operatormay,

either kneel or sit thereon when operating the levers 36 and 37, and also for acting as means for preventing the free end of the frame from rising when the teeth 38 are pulling. "It will be noted that the teeth 38 are connected toa plate' 39, and this plate is held in position by suitable screws 40. The teeth 38 may be welded or other-- wise rigidly secured to plate 39, and this plate may be secured to the plateor block 39' by screws or otherdesirable fastening means. The teeth 38 are preferably comparatively long but in order to shorten their effective length one or-more aux iliary plates 39" are slid loosely over the teeth, as shown in Fig. 8, and are merely held thereon by friction. The intentionis to have the effective length of. the teeth suflicient to puncture and-extend almost through the rug without digging into the floor. Also, it will be noticed that'there are,- in fact, rows of teeth-so that the rug will be engaged at a large number of points. As shown in Fig. 2 the chain structure 27 reacts against the link 25 and associated parts and is wound around thedrum 29 which is preferably a solid rod. This rod isjournaled in the standards 30. A com-,

paratively large gear wheel 41 is rigidly secured to the drum 29 and continually meshes with the pinion 42 which is rigidly secured to shaft 43, also journaled in standards 30.

' the shaft to be ,free when the levers 36 and 37 are moved .to a central point, namely, on the rounded section 44. V J Y The levers 36 and 3'7 are each provided with a bifurcated portion,4'7 and in these portions is an aperture 48 through which the hub 49 of a ratchet wheel 50 extends. The ratchet wheel is held against reverse movement by the spring pressed pawl 51, which pawl has a thumb member 52 whereby it may be manually lifted away from the ratchet wheeland turned so that the surface-53 will engage the spring 54, which will thus hold the pawl out of operative position. The ratchet wheel 50 has a borewhich is hexagon shaped and of a size to slide over the hexagon shaped sections 45 and, 46 of rod 43. Byreason of this construction when the levers are in'their respective positions as, shown in Fig. '7, they may be swungback and forth' and in doing so will rotate the shaft 43 in one direction, which in turn will rotate the pinion 42 and this pinion will rotate the gear 41 which is rigidly secured to drum 29, thus causing the drum to wind the respective sections 2'7 and 27". This winding action will cause the entiredevlce 7 to move toward the bar 9 and, consequently, will stretch the rug 2. It will be understood that the device 7 may be shifted from time to time along the bar 9, and when shifted the clevis 24 will also be slid along the bar 9. After the rug has been stretched longitudinally to line 5, as shown in Fig. 1, which may be left loose or tacked to the floor, then the device 9 and anchoring structure 8 may be moved around to the side of the rug and the operation repeated for stretching the rug transversely.

As shown particularly in Figs. 7 and 8, the stretching device '7.has been positioned to stretch. a piece of carpet '55 so that it will be near or touch the wall, 56. In order to accomplish this result a block 39 is interposed between the plate 39 and the plate 34, whereby the stretching device'will be raised in order that the bar 9 may pulleys are mounted on suitable brackets connected-to the rear of the frame 59.

- It will be noted that the chain sections extend over the pulleys, as just mentioned, and then back to a point near the bar 9, where they are connected to the bar in a similar way to the showing-illustrated in'Fig. 1. When the parts have been mounted as just described, the levers' 36 and 37 are swung backand forth to rotate the drum 29 which will cause the frame 59 to be urged forwardly'or towards the wall 56. If the frame 59 and associated parts should tend to rise, the operator may kneel or sit on the seat 35 and hold the same in proper position.

The, stretching structure described has been shown stretching a rug and also a carpet. It is ,to be understood, however, that the device may 'be used in other ways for stretching rugs or carpets or, in fact, for stretching any articles, and also thef'stretohing device 7 may be anchored-as shown-in Fig. 8, or in anyother desired manner without departing from the spirit of-the invention. 4

I claim:- I I v 1. A carpet and rug stretcher, including a frame, means carried by the frame for engaging the carpet or rug, an anchoring structure provided with a bar extending transversely of said frame and spaced away from said frame, means arranged at each end of the bar for anchoring the'bar, means for connecting the bar with said frame, said means including a clevis slidingly mounted on said bar, a flexible structure connected with the clevis, and a drum carried by the frame on which part of the flexible structure is normally wound, and manually actuated means carried by the drum for rotating the drum so as to windthe flexible structure thereon and thereby pull the frame and associated parts towards said bar. 1

2. A" rug and carpet stretcher, including an anchoring structure comprising a bar, a plurality of chains, there being onechain connected to each end of the bar, a hook member carried by each chain, a fixed anchoring eye plate disengageably interlocking with the respective hooks whereby the bar is anchored against movement in one direction, and means connected to the bar for engaging and pulling the carpet or rug towards the bar.

3. A carpet and rug stretcher including an anchoring device and a link, a hook member disengageably interlocking with said link, a flexible structure including a pair of chains connected with said hook structure, a drum secured at the opposite end of said chains, a frame on which said drum is rotatably mounted, a gear wheel rigidly secured to said drum, a pinion continually meshing with said gear wheel, a lever associated with said pinion, a pawl and rack connecting said lever with said pinion, and toothed means extending from said frame for engaging said carpet or rug, whereby when said drum is rotated for winding said chains the frame will be moved toward said anchoring structure and the rug or carpet stretched.
