CARPET-RAVELING MACHINEll Specification of Letters Patent.
Patented Aug. 8, 1905.
Application flled February 1, 1905. Serial No. 243,615.
To a/ZZ whom it may concern:
Be it known that I, FREDERICK H. WILMs, a
Improvements in Oarpet-Raveling Machines,
of which the following is a specification.
My invention relates to machines used in the manufacture of rugs from carpet after the carpet has been cut into strips with the warp of the carpet running lengthwise thereof to pick all the warp from the strip except a few strands near the middle thereof.
The object of my invention is to provide a machine that is easy to operate, accurate, not liable to become clogged, and to lessen the liability of damage to the machine in the event of its becoming' clogged.
My invention consists in a combined fender and feeding-gage, an adjustable-bladed picking-head, improved means for rotating the picking-head, and a loosely-mounted ring adjacent the picking-head.
My invention also consists in the parts and the combination and arrangement of the parts, as will hereinafter be more fully described.
In the drawings, Figure 1 is a plan view of a machine embodying my invention. Fig. 2 is a front view of the same, a portion of the bed being represented as broken away. Fig. 3 is an enlarged front viewof my improved picking-head unit. Fig. 4 is an edge view of the same. Fig. 5 is a view of one of the knives. Fig. 6 is a sectional view` and Fig. 7 an elevation, of one of the plates with the screw for attaching it. Fig. 8 is a front View, and Fig. 9 is an edge view, of the ring. Fig. 10 is a section on the line of Fig. 1 or Fig. 2. Fig.v 11 is a perspective view of the combined fender and Afeeding-gage.
The machine is constructed as follows, reference being had to the drawings.
The bed 1 has the shaft 2 journaled in it at 3, and the serrated feeding-disk 4 is rigidly mounted on the shaft 2 and likewise a pulley 5 for rotating the shaft. Other shafts 6 are journaled in the bed at 7 at right angles to the shaft 2. Upon the shaft 6 are rigidly mounted the picking-heads 8 by means of the nuts 9 and collars 10. Secured in the bed 1 and adjacent the periphery of the feeding-disk 4 is the feed-bar 11. The combined fender machine, in alinement with the feed-bar 11, so as to guide the strips of carpet into the space between the feeding-disk 4 and feedbar 11.
The picking-head 8 is built up of a number of the units 14. This unit 14 consists of a disk slotted or grooved radially and having a central bore and key-seat, as shown in Fig. 3. The thin blade 15, of less width than the slot or groove in the disk, is formed with the longitudinal slot 16 and is adapted to fit into the groove in the unit 14 and be held from turning by the sides of the groove. The plate 17, of the same width, is likewise adapted to fit into the groove over the blade 15 and is secured to the unit 14 by the screw 18 taking through a hole in the plate 17 and through the slot 16 into the unit. Preferably the blade is ground sharp at 19 and 20. The ring 21 consists of a disk having a central bore to admit the shaft 6 loosely and is mounted on the shaft loosely between the picking-head 8 and the bearing 7. Each of the shafts 6 has a pulley Q2 rigidly mounted on it, and a belt is passed around the pulleys 22 and around the idler 23 in such a manner as to revolve the picking heads 8 toward each other. The clutch 24 is provided for connecting the machine to a second machine, part of the shaft of which, 25, is shown.
The operation of the machine is as follows: The strips of carpet are fed endwise into the opening 13 in the gage 12, the operators hand being protected from injury by the upwardlyextending lip of the gage, which thus forms a fender. The carpet strip is engaged between the disk 4 and the feed-bar 11, with its edges projecting' over the sides of the feedbar, where they are acted upon by the blades of the rapidly revolving picker heads on either side to remove the warp from the strips, leaving only a few strands of warp in the middle portion of the strip.
The warp removed or picked from the carpet is liable to become wound around the shafts 6 between the picking-heads and the bearings 7, holding the heads stationary and causing damage to the machine. I overcome this difficulty by providing the rings 21,
which prevent the chain from becoming wound around the shafts. I have also substituted the pulleys 22 for the gear-wheels heretofore generally used on the shafts 6, they being more satisfactory in that the gearwheels will strip if the machine becomes clogged, whereas the belt will slip on the pulleys, causing less damage.
By providing the machine with my improved adjustable-bladed picking-head the blades can be moved away from the center of the head as they wear out and clamped securely thereto, whereby the picking-head is maintained of the required diameter.
What I claim as new, and desire to secure by Letters Patent, is
l. In carpet-picking' machinery, a feeding device and means for operating said feeding device, a picking-head, a shaft rigidly secured to said picking-head, a bearing for said shaft, a ring loosely mounted on said shaft between said picking-head and said bearing and means for rotating said shaft.

6. In carpet-picking machinery, the combination of a feeding-disk mounted on a hori- Zontal shaft, means for rotating' said feedingdisk, a feed-bar under said feeding-disk and adjacent the periphery thereof, a fender having an opening in alinement with said feedbar and with said feeding-disk of a Width corresponding to that of the strips of carpet to be picked by said machine, a second horizontal shaft journaled at right angles to the shaft upon which said feeding-disk is mounted, a
pulley rigidly attached to said shaft near one end thereof, a picking-head rigidly attached to said shaft near the other end thereof, a blade and means for adjustably securing said blade in said picking-head, and a ring loosely mounted on said shaft between said pickinghead and the Ijournal of said shaft as and for the purposes herein specified.
7. In carpet-picking machinery, a feedingdisk and means for rotating said disk, a feedbar adjacent said disk, a radially-grooved picking-head unit, a shaft` and means for securing said unit to said shaft, a blade of less width than the groove in said unit having a longitudinal slot therein, means for securing said blade in said groove, and means for rotating said shaft.
