Y To all whom t may concern:

Be it known that I, RnUBnN J. GRUBB, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Apparatus for the Manufacture of Rugs, Mats, 85e., which improvement is fully set forth in the following specication and accompanying drawings.

My invention relates to improvements in apparatus for manufacturing rugs, mats, 85e., of the class formed of a body or piece of suitable material, with tufts of yarn passed through the same and appearing on the faces thereof.

bimilarfletters of reference indicate corresponding parts `in the several figures.

Referring tothe drawings: Adesignates the frame of the apparatus, in the upper portion of which are secured a series of plates B, one placed above another and separated,

leaving spaces C between adjacent plates, so that bodies or pieces D of` material may be placed in the same, it being noticed that said bodies, which may be made of soft rubber or other suitable material, are perforated so that yarn or th'read E may be inserted in the perforations, so as to form tufts on both sides of said bodies, as will be hereinafter described. The plates B are serrated as at F, forming the slots G which are adapted to receive hooks H, which draw the yarn or thread E through the perforations in` the bodies, said hooks being connected with a rising and falling cross head D', guided in the frame A, andsaid cross head D receivingmotion by means of` screws J which are rotated by Worm Wheels K thereon which mesh with worms L on a shaft M..

N designates sliding plates, the same being in line with the plates` B and provided with the side extensions P, which travel in the guides Q secured to the frame A. See Fig. 3.

Secured to the edges of the plates N are tingers'Iv which are guided in the plates B, and whose free ends are adjacent to the slots J in said plates B, and adapted at certain times to press against the feeding pins K working in said slots, so as to advance the said feeding pins and carry with them the bodies D, for a purpose to be hereinafter described. In said extensions P of the plates N are the openings VR in which work the eccentrics-S, said eccentrics being secured to the shafts a having thereon the bevel gear wheels Z which mesh with the bevel gear wheels A on the 4shaft B', which is journaled in the frame A. Secured to said shaft B is a lever C whereby the same can be rotated, thus imparting motion to the shafts a and thereby to the eccentrics S and plates N. i

The feeding pins K are secured to a'sliding plateU, which is guided on a rising andfallhead V,\by bolts X, which enter slots Y in said plate, it being evident that by this con nection said plate will rise and fall with the cross head V, and also move to and fro with the sliding plates N, so asto press the fingers T against the feeding pins K and move the same with the body D, the object of these various motions being to cause the feeding pins K to pass through the perforations in the bodies D and when required to carry the latter forward. The plates B are also provided with grooves L, in which travel the edges of knives M adapted to cut the yarn passed through the perforations in the bodies D. See Fig 8.

Plates Y' extending from the ends of the frame A, parallel with the plates B serve as guides for the knives M, said knives being adapted to be drawn to and fro by means of wires Z' or in lieu thereof cords, chains, 85e., which may be operated by hand, oriu any suitable manner, it being noticed that the shanks M of the knives are slotted as at D2 see Fig. 8 to receive said plates Y' and slide therein, the friction being greatly reduced by rollers VE2 mounted within said slots, and contacting with the edges of the plates when the knives -are in motion.

,said pins A2 is engaged by screws C2 and that when it is desired to tighten said plates by properly rotating the screws C2 they cause the pin A2 to move from the frame A, and thus prevent sagging of said plates. See Fig. l0.

Motion isimparted to the cross headV by screws F. which are rotated by the worm wheelsF' thereon which mesh with Worms Gr' mounted on a shaft H'.

In orderto cause the screws E' to revolve from right to left, a clutch N secured to the shaft H iscaused to engage a` pulley P loosely mounted on said shaft, and driven. by an open belt Q. "When it is desired to reverse the motion of the screws E', the clutch N' is caused to engagea pulley R loosely vmounted on the lshaft H', and driven by a cross belt S', it being evident that the cross headV will be either raised or loweredY according to the direction in which the screws E revolve.

In order to cause the screws J to revolve i Mounted within the Shanks M' of the knives M are eccentrics F2 adapted to act as an abutment for the knife blades G2, it being noticed that any wear on said blades `may be taken up by said eccentrics, and the latter after being adjusted may be firmly retained in posi tion by screws H2 working in segmental slots J2 in said Shanks M'.

K2 designates a frame provided at opposite sides with slots L2 and M2 through which is passed the yarn to be supplied from a reel, cop, &c., the slots L2 being open from below, as clearly shown in Figs. 6 and 9.

Secured to the frame A above the plates Bis a box N2 open at top and bottom and formed of pieces which have on their inner upper edges the cushions P2 of soft rubber or other suitable material. The frame K2 is adapted to be seated in said box N2 and when in position the cushions P2 contact with the sides of said frame K2 and engage the yarns E so that the portion thereof within said box is held perfectly taut when fed to the hooks H, but when the latter exert a downward force or pull on the said yarn, the slight tension of the cushion on the yarn is overcome to such an extent that it permits the movement of the yarns from both sides, so thatadouble thread may be drawn through each of the openings in the bodies D.

The operation is as follows: A body or piece D of perforated rubber, or any suitable material is inserted, in the present case by hand, in each space C, and advanced therein until the foremost row of openings in said body is in alignment with the row of hooks H, which latterare in their lowermost position, or below the plates B. See Fig. 4. The clutch T is then caused to engage with the revolving pulley U', which owing to the worms L' and worm wheels K', cause the screws J' to revolve, and thereby raise the cross head D', so that the hooks H secured to the same will enter and pass through the aligned perforations in the several bodies D, and their noses project above the latter so that the yarn in the frame K2 may be supplied to said hooks. See Figs. 6 and 9.' The clutch T' is disengaged from the pulley U as soon as the hooks H have been raised the desired distance, The frame K2 having had yarn passed between the' slots L2, in the present case by hand, and drawn through its slots M2, see Fig. 9, is inserted in the box formed by the pieces N2 as shown in Fig. 6, it being noticed that the distance between. the slots L2 and the distance between the slots` M2 is the same as that between the hooks H. SeeFig. 9. The clutch N' is then caused to engage with the revolving pulley P', which owing to the worms G and worm wheels F' cause the screws E' to revolve and thereby raise the cross, head V, which was in its .lowermost position, so that the feeding pins K secured to the same will enter the aligned perforations in the several bodies D, see Fig. 6, the clutch N' beingv disengaged from the pulley P', when said feeding pins K have been raised the desired distance. The clutch T is then caused to engage with the revolving pulley X', which owing to the worms L' and worm wheels K cause the screws J to revolve in an opposite direction from that described in connection with the pulley U', so that the cross head D is lowered, and with it the hooks H, the latter in descending engaging and carrying with them the yarn they received from the frame K2, and drawing a doubled strand of the same through the perforations in the bodies D. Each knife blade G2 which is normally at one extremity of the supporting plate Y is then drawn from one end of the latter to the opposite one by the wires Z', either from right to left or viceversa, as the case may be, so as to cut the tightly held yarn in their path, as shown in Figs. 6 and 8, and thereby disconnect one body D from another and leave the yarn in the perforations in each bodyD project from both faces thereof, so as `to form tufts, as shown most clearly in Fig. l2. The parts are so timed that when one row of openings in the body pieces has been tufted, the operation of the sliding plates N laterally moves the rods W and the Vplate Uwith the feeding pins so that the body pieces D are advanced in the frame and another rowr of openings isin line with the hooks H, when the latter are rising, and the operation as before described is repeated. The yarn is placed in the frames K2 by hand or by any suitable mechanism,

`before each rising of the hooks H so as to be around the yarn in the perforations and Iirmly hold the same in position, while the portions of yarn not in contact with the bodies D will spread and form tufts, `as shown in Fig. 12. After a set of bodies D have been tufted or converted into rugs, a newr set of bodies may be inserted in the spaces C and the operation as described herein repeated.

The operation hereinbefore described is repeated each time a row of perforations is brought in the path of the hooks H by the action of the needles K advancing the bodies D, until the desired length of the rug, mat, dac., has been obtained, when the rug, dro., is removed and another series of bodies D may be placedin the apparatus, and the operation hereinbefore described of forming a rug, mat, rbc., repeated.
