CARPET-STRETCHER.

Specification of Letters Patent.

Patented May 28, 11912.

Application led .Tuly 18, `19711. Serial No. 639,108.

To all whom it may concern Be it known that I, JAMES A. G. SEYBOLD, a citizen of the United States, residing at Harvard, in the county of Clay and State of Nebraska, have invented new and useful Improvements in Carpet-Stretchers, of which the following is a specification.

This invention relates to carpet stretchers and one of the principal objects of the invention is the provision of a device of this character which will lie close to the floor and which will operate to stretch the carpet at both ends or sides.

A further object of the invention is the provision of a carpet stretcher having two telescope ends with carpet engaging members arranged thereon and an intermediate section adapted to adjust the ends away from each other, so as to stretch the carpet after the gripping devices have been properly located by extending the end members to the required degree.

A still further object of the invent-ion is the provision of a device of this character wherein the gripping members are provided with means for regulating the depth of insertion of the teeth into the carpet so that light and heavy fabrics may be operated upon with equal results.

Further objects ofthe invention will appear as the following specific description is read in connection with the accompanying drawings, which form a part of this application, and in which Figure 1 is a side elevation. Fig. 2 is a top plan view. Fig. 3 is a detail longitudinal section. Fig. 4 is a detail top plan view of one of the gripping surfaces. Fig. 5 is a side elevation of a modified form. Fig. 6 is a top plan view thereof. Fig. 7 is a detail horizontal longitudinal section.

Referring to the drawings, and more particularly to Figs. 1 to 4, each end of the device is composed of a pair of telescoping sections 1 and 2, the section 2 telescoping within the section 1 and being provided with a plurality of holes 3 which are engaged by spring pressed latches 4 pivoted upon the ears 5 secured to the section 1. If preferable, the section 2 may also have a latch, as shown at 6, so as to receive the end of the gripping device supporting tube 7. This supporting tube is connected to the gripping device by a union 8 and is preferably riveted to the section 2, as shown in Fig. 3. One

end may be treated, as shown in Fig. 3, by riveting the supporting tube 7 to the section 2 and the opposite end may be arranged as shown in Fig. 1 wherein, at one end of the device, the section or supporting tube 7 is adjustably mounted in section 2 and in the opposite end the supporting tube7 is riveted to the section 2. The gripping device at each end comprises a curved plate having a plurality of elongated teeth 9 extending outwardly and downwardly so as to engage the carpet being stretched. In order to regulate the depth of engagement of the teeth a plate 10 is adjustably secured to the underneath side of the arm by means of a bolt 11 which operates in the slot 12. The plate has its rear end adjustably engaged with one of a series of rack teeth. 13 so that when in engagement with the rear tooth of the series the full length of the teeth `will be exposed and when engaged with the forward tooth of the series only a short length of tooth will be exposed. Therefore the teeth will not enter the carpet'to any great extent. vIn one of the inner sections or tubes there are mounted at its end guiding blocks 14 between which is slidably mounted a rack bar 15 with teeth upon opposite sides thereof arranged in staggered relation. Suitable plates 16 are secured to the sides of the section and extend beyond the end thereof on opposite sides of the rack bar 15 and pivoted to these plates are the opposite legs 17 of a bifurcated operating lever 18. This lever carries a pair of spring actuated dogs .19 which are adapted to alternately engage the teeth upon the opposite sides of the rack bar, so that it may be properly moved out of the section in which it is slidably mounted. The opposite end of the rack bar is riveted to the opposite section 1 between filler plates 20. In order that the rack bar may be telescoped within its proper section, the dogs 19 are provided with rearwardly extending outwardly curved lingers 21 by which they may be simultaneously released from the teeth of the rack bar.

In using the device the separate sections of the respective ends of the device are extended to the required degree and the gripping devices engaged with the carpet also to the required degree by adjusting the plate 10 for the weight of the particular carpet being operated upon. The lever 18 is then reciprocated and the rack bar forced out of the section 1 which it operates, thus separating the inner sections l and properly stretching the carpet.

The tubular sections may be of any cross sectional formation.

In the modification shown in Figs. 5 to 7, 22 shows a tubular section in which is slidably mounted a bar 23 having its opposite end rigidly connected to a similar bar 24. The bar 24 is adjustably connected to a bar 25 which is provided with a longitudinal slot 26 adapted to receive the clamping bolt 27 carried by the bar 24 and also a rivet 28 carried by the bar 24 in advance of the clamping bolt 27. The outer end of the bar 26 is preferably reduced and threaded so as to connect the clamping bar 29 by means of a union 30. The clamping' member 29 is similar in all respects to the clamping member described in Figs. l to 4 and therefore needs no further description. The opposite end of the tubular bar 22 has passing therethrough a clamping bolt 31 and a rivet 32 which are adapted to operate in a slot 33 formed in the adjusting bar 34. The opposite end of the adjusting bar is provided with a rivet 35 and a clamping bolt 36 upon which the end bar 37, also provided with a slot, is adapted to operate. This end bar is reduced so as to connect with the grippingmember 39 by means of a union 40. In each instance where the rivets are employed clamping screws, such as those shown at 27, 31, etc., may be substituted. A bifurcated lever 4l straddles the inner end of the tubular bar 22 and is pivoted to the same, as shown at 42. Upon opposite sides of the bar 22 there are pivoted to the lever suitable links 43 and 44, both carrying gripping` members 45 which surround the bar 23 and in their retrograde movement abut against shoulders 46 formed upon the ends of lthe links. In their forward movement they tilt upon the bar 23 and grip the same, as shown, to force it out of the tubular member 22. IVhen the bars, such as 24, 25 or 22, 23, have been adjusted apart, the lever 41 is reciprocated to force the bar 24 out of the tube 22.

In both types of the device the sections lie in substantially parallel planes with the carpet to be stretched and each end is properly adjusted, so that the gripping devices will engage the sides or endof the carpet and the lever then operated to stretch the carpet to the required degree. Also in each structure the end sections have secured thereto the adjustable carpet gripping members which, as before stated, arevadapted to operate with equally good results upon both light and heavy carpets, the penetration of the grippingteeth being controlled by the adjusting plate.

IVith this type of device, after the lever has been operated and theV carpet stretched, the same operator can tack the carpet in' its place and then release the stretcher. This type therefore has advantages which are not found in the toggle type stretchers.

Having thus described the invention, what I claim as new is In a carpet stretcher, adjustable stretching members, a head thereon having carpet engaging teeth, a plate adj ustably secured to the under side of the head and overlapping the teeth to control the depth of engagement thereof, and a rack carried by the head and adjustably engaging the plate for holding it in adjusted position.

In testimony whereof I affix my signature in presence of two witnesses.
