Application February 27, 1950, Serial No. 146,532

This invention relates to new and useful improvements and structuralrefinements in devices for making hooked rugs, and the principal object of the invention is to facilitate convenient and expeditious insertion or threading of yarn through woven fabric so as to form a series of loops which eventually cover the entire fabric and coact therewith to provide the rug.

One of the important features of the invention resides in the provision of means for propelling or advancing the device at proper intervals along the surface of the work in response to the reciprocating movement of a yarn needle, while another feature of the invention resides in the provision of means for removably retaining the yarn needle in position, so that several needles threaded with yarn of different colors and thicknesses may beselectively used for the formation of different patterns in the rug.

Some of the advantages of the invention reside in its simplicity of construction, in its efficient and expeditious operation, and in its ability to produce hand made work as distinguished from work done by a power driven machine.

With the above more important objects and features in view and such other objects and features as may become apparent as the specification proceeds, the invention consists essentially of the arrangement and construction of parts as illustrated in the accompanying drawings, in which:

3 Claims. (Cl. 11280) Like characters of reference are employed to designate like parts in the specification and throughout the several views.

Referring now to the accompanying drawings in detail, more particularly to Figures 1-7, inclusive, the invention consists of a hooked rug making device which is designated generally by the reference character It! and embodies in its construction a vertically elongated frame l2 preferably assuming the form of a strap having horizontally angulated upper and lower end portions [4, !6, respectively, the lower end portion A6 of the frame being provided with an aperture 18 while another aperture 20 provided in the upper end portion I4 accommodates a fastening element 22 for securing a suitable handle 24 to the frame.

A carrier consisting of a flat strap 26 is reciprocable vertically on the inner surface of the frame l2 which is achieved by providing the carrier with a pair of studs or rivets 28 slidable in a vertical slot 30 with which the frame [2 is formed.

A pair of resilient clamps 32 are secured at vertically spaced points as at 34 to the carrier 25 andare adapted to frictionally engage a removable, tubular needle 36 which has a diametrically reduced lower end portion 38 projectible downwardly through the aforementioned aperture l8 beyond the lower end portion 16 of the frame l2.

The tubular needle 36, 38 is adapted to have the yarn 40 extended therethrough as shown in Figures 1 and 4 and if desired, an apertured tensioning bracket 42 may be provided on the carrier 26 so that the yarn may pass through it before entering the upper end of the needle, substantially as shown.

It is to be noted that by virtue of the resilient clamps 32, the needle may be readily removed and replaced by another having a yarn of a different color or thickness threaded therethrough.

Reciprocation of the carrier 26 and of the as sociated needle is effected by a crank handle 34 secured to a shaft or pin 46 which is rotatably journaled in the frame I2 and also carries a crank 48, the latter being provided with a plu rality of apertures 59 to selectively receive a pivot pin 52 provided at the upper end of a pitman arm 5d. The lower end portion of this arm is pivctally connected as at 58 to the carrier 26 so that by simply rotating the hand crank 44 the carrier together with the associated needle may be reciprocated between projected and retracted positions, as shown in Figures 2 and 3, respectively.

Moreover, by simply placing the pivot element 52 in the different apertures 5B, the extent or stroke of the reciprocating movement of the carrier and needle may be varied as required.

When the invention is placed in use, the lower end portion (6 of the frame 52 is adapted, of course, to engage the work, and the invention also includes means for propelling or advancing the device along the surface of the work each time the needle is reciprocated.

These means consist of what may be called a shoe 58 which is pivotally mounted as at 80 on the frame I2 adjacent the portion l6, and is provided with a plurality of teeth 62 which engage the Work and cause the device to advance each time the needle portion 38 is retracted upwardly from the fabric.

Oscillation of the shoe 58 is effected b means of a link 64 which is pivoted as at 66 to the shoe and is provided with a longitudinally extending slot 68 to slidably receive apivot element orstud 10 which is rigidly secured to the carrier 28uand projects outwardly through the slot 30 of the frame I2.

.The slot 68 is of such length that the stud l9 abuts the end of the slot and reciprocates the link 64 only at the upper end of the stroke of the carrier 26, that .is, while the lower portion 38 of the needle .36 is retracted upwardly through the aperture 18. In other words, when the crank handle 44 is rotated so as to slide the carrier 26 and the needle thereon downwardly through the fabric, the link 64 is stationary and the shoe 53 is substantially in the position shown in Figures 2 and 4. However, when the needle travels upwardly and almost reaches the upper end of its stroke, the link '54 is slid upwardly by the stud 10, thus causing the shoe 58 to swing downwardly'to the position shown in Figure 3 so as to advance the entire device along the surface of the work. The "magnitude of the advancement or step may be varied by simply holding the device at different angles from the perpendicular, and needless to say, as soon as the needle "again commencesits downward travel, the shoe 58 is swung upwardly to its inactive position.

In the modified embodiment of the invention illustrated in the accompanying Figures 8 and a shoe T2 is substituted for the shoe 58, the shoe I2 also being of 'an oscillatory nature and being pivoted to .the frame l2 by a stud .14. However,

the shoe i2 is of such dimensions as to extend forwardly as well .as .rearwardly from theirame l2 :and is provided with two setssof teeth 76, 18.

The shoe E2 is provided with an arcuate slot 88 which is concentric with the stud 14 and terminates .at the ends thereof :in enlarged por- .tions or apertures 82, B4, -theslot-80 being adapted to slidably receive a diametrically'reduced shank [i6 provided at one end of a pivot element 33 which is secured to the free end portion ofa leaf spring 90. Ihe latter is also formed withan aperture 92 for pivotaLmounting .on the aforementioned stud id and the shank .86 and the-pin 88 extend through an aperture (not shown) provided in the lower end portion of the aforementioned link 64, whereby the link is operatively connected to the shoe 12.

The diameter of the main body portion of the pin 88is such as to fit in the apertures 82, 84, so that when the pin 88 is in the aperture 82 as shown in Figure 8, the teeth 75 .of the shoe 72 may engage the work so as to propel the device forwardly, thatis, in the direction of the arrow 92. However, by simply pulling the main body portion of the pin 88 out of the aperture 82 and sliding the shank 86 through the slot 35 so that the pin 88 may be inserted in the aperture 84, the shoe 72 will be swung in an anti-clockwise direction, so that the teeth 18 may engage the work and propel the device rearwardly as indicated at 94. It is to be noted that the sliding of the shank 86 through the slot 30 may be effected 'without disconnecting the link 64 from the pin 88.

It is believed that the advantages and use of the invention will be clearly understood from the foregoing disclosure and, accordingly, further description thereof at this point is deemed unnecessary.

While in the foregoing there has been shown and described the preferred embodiment of this invention it is to be understood that minor changes in the details of construction, combination and arrangement of parts may beresorted .to without departing from .the spiritand scope of the invention as claimed.
