rllhe sewing mechanism is composed of the usual operative parts comprising the vframe 1, main shaft 2 j ournaled. therein and driven from the jack shaft 8 through the medium of the pinion 4 on said jack shaft, meshing with the large gear 5 on shaft 6, and the pinion 7, Fig 2, on the main shaft 2. Needle 8, needle carrying slide 9, slide operating cam lever l0, shuttle race 11 carrying a shuttle (not shown), delivery spools 12-13, and

other parts fully'illustrated and described in l `forth'e different style of stitching, such as lock stitching, loop stitching and serging or selvage work when operating with the pluc'king mechanism. l

The .plucker frame -14 is mounted on the trolley frame v19, with its trolleys 720 engaging the rack 21. The mechanism for feeding the combined plucking and sewing mechanisms along the rack comprises the rod 22, Figs. 3 and 6, secured to the trolley frame; the worm gear 23 rotating on said rod, eccentric 24 free on said rod but secured to the worm gear, ratchet gear 25 free on said rod but secured to the gear 26 meshing with the rack 21. The pawl 27 is pivoted to the eccentric strap 28, which strap is suspended to swing from the upper surface of the trolley frame 19 by the pin 29. This 'feeding mechanism is actuated from the worm gear 30, Fig. 7, secured to the main shaft 81 of the plucker mechanism and the worms 32 and 33 (see also Fig. 3) carried by the vertical shaft 34. The shaft 31 is rotated direct from the motor 35, mounted on the plucker frame, through the medium of the pulleys 36--37 and the vertical belt 38, Fig. 2, and the jack shaft 3 of the sewing mechanism is rotated through the medium of the horizontal belt 39 and pulleys 40 and 41.

rlhe vertically operating plucker jaws 42 and the pitman 43 pivotally supported on the eccentric pin 44, like the mechanism previously described for the detail mechanism of the sewing mechanism, forms no part of my present invention.

The carpet 45 is stretched between the usual horizontal clamp 46 and vertical suspension clamps, one of which vertical clamps, 47, is shown.

rlhe guide 48, Figs. 2, 8, 10 and 11, is carried by the sewing mechanism and is forked to embrace the two parts of the carpet, and 49 is the carpet separator which may be integral with the guide or removably attached thereto, and 50 (see also Fig. 9) is the nap or plush spreader connected with the separat-or and is located just in advance of the needle, which needle operates through the eye 51, Fig. 10, of the guide. The angular shape of this Spreader will separate the nap 45a, Fig. 9, of the carpet and hold it apart so that the needle, following immediately after the spreader, will pass through the carpet and not draw the nap or plush into the seam, and when the ends of the carpet are sewed together,`the seam cannot be seen from the upper' or plush side of the carpet by reason of the fact that the nap or plush has not been disturbed;

rlfhe carpet spreader 53, Figs. 8 and 10, follows immediately after the sewing mechanism and is shown connected to the guide 48, although it could be connected to the vmachine frame of the sewing mechanism `withecpially as good result. rlhe object of this spreader is to open the two edges of the carpet above the seam and hold them apart while the plucker jaws remove the nap or plush from these opened edges. The forward end of this carpet spreader is pointed or angular to more readily separate the edges of the carpet directly back of the guide, but the rear portion 53 is made flat or horizontal in order to keep the two edges of the carpet in a horizontal position for the plucker to operate and remove the nap or plush.

rlhe plucker jaws follow immediately after the carpet spreader and are pivotally connected, by their pitman 43, to the pin 44, as before mentioned. rlhis pin, Figs. 1 and 19, particularly the latter figure, is attached to the presser foot actuating cam 54 mounted on the main shaft of the plucker mechanism. This cam imparts a vertical movement to the presser foot 55, its object being to hold the two edges of the carpet firmly down upon the anvils 56-57, while the plucker jaws are operating. rFhese anvils are secured to the machine frame of the plucker mechanism; the front one, 5G, being shown in Fig. 1. Referring again to Fig. 14, the

horizontal feet

56, 57a form the anvils proper, the turned over1 edges of the joined carpet lying on these anvils while the vertical portion of the carpet will be Suspended between said anvils in the space represented by A.

The horizontal portion 'r1 of the presser foot is first brought firmly down upon the turned over edges of the carpet and remains in forcible contact therewith until the plucker jaws have performed their work and have retreated a short distance when the presser foot will also retreat. |The plucker jaws operate through the opening 55h, Fig.

8, of the horizontal portion of the presser foot when said foot is in contact with the carpet.

Means for temporarily disconnecting the plucker mechanism from the sewing mechanism is shown in Figs. 4 and 5. 58 is a collar mounted on the main shaft of the plucker mechanism, having a hole therethrough to receive the longitudinally operating bolt 59 also operatively located in the housing 60 and backed up by the spring 61. When the plucker mechanism and sewing mechanism are working together, the bolt 59 is engaged with the collar 5S as shown in Fig. 4, and when disconnected the bolt is withdrawn as shown in Fig. 5. rlhe presser foot operating cam 54 is held against the collar 58 by the screw 62.

The bar 63 of the carpet clamping fixture, Figs. 15, 16, 17 and 18, is removably supported on the end brackets (S4-65, by the bolts 66-67, and nuts (S8-69. The clamp 70 is hinged to this bar by means of the two end levers 71-7 2 pivotally supported on the screws 73-7 4. The clamp is provided on its inner edge with the teeth 75 adapted to engage the overhanging edge c, Fig. 18, of the carpet and grip the same firmly against the inner vertical face of the bar 63 where it is held temporarily by the spring snap 76 as shown in Fig. 17. The scale B on the lever 7 2, in connection with the Zero mark on the bracket, determines the amount of area of the carpet to be plucked by simply adjusting the position of the bar on the supporting brackets with respect to the iXed location of the plucker jaws which overlie that portion of the carpet represented by C. The brackets 64--65 are removably supported on the machine supporting standards or legs 77 and 78 (see also Fig. 2).

The blower case 79, Fig. 2, contains a blower (not shown) adapted to remove the nap or plush extracted by the plucker jaws and deliver the same through the discharge spout 80 at the rear of the machine. The blower shaft 81 is driven from the motor through the medium of the pulleys 82-83 and-belt 84.

The combined carpet sewing and carpet plucking mechanism operating together as one concrete machine enables the plucker jaws to follow immediately behind the sewing mechanism and thus accomplishing in one operation what would otherwise require two operations.

Having thus described my invention, what I claim is y l. A device of the character described, comprising combined carpet sewing and carpet plucking mechanism operatively connected together, and a support on which the combined mechanism is adapted to travel.

2. A device of the character described, comprising combined carpet sewing and carpet plucking mechanism, means for actuating the carpet plucking mechanism, and means for actuating the carpet sewing mechanism from the plucking mechanism.

4. A device of the character described, comprising combined carpet sewing and carpet plucking mechanism, kand means for temporarily halting the plucking mechanism while the sewing mechanism is in operation.

5. A device of the character described, comprising carpet sewing and carpet plucking mechanism, a carpet spreader located between the two mechanisms adapted' to open the edges of the carpet above the seam and hold said edges apart while the plucking mechanism is in operation.

6. A device of the character described, comprising combined carpet sewing and carpet plucking mechanism, a guide adapted to embrace the edges of two strips of carpet, a carpet separator within the guide and between the edges of the carpet, and a nap spreader adapted to spread the nap of the carp-et in advance of the stitching mechanism.

7. In combination with carpet stitching and carpet plucking mechanism of a clamping device comprising a bar, a clamp pivotally supported thereto having a serrated inner edge adapted to grip thecarpet against the inner vertical face of the bar, and means for ,adjusting the bar with respect to the plucking mechanism.

8. In combination with carpet stitching and carpet plucking mechanism having plucking jaws, a guide embracing the carpet,

a carpet spreader following the guide and adapted to open the edges of the carpet above the seam, anvils connected with the plucking mechanism and located below the plucking jaws, and an independently operating presser foot adapted to hold the edges of the carpet against the anvils while the jaws are operating, and to remain in contact with the carpet until the completion of the plucking operation. 4

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