1 Claim.

The principal objects of this invention are to provide a felting or needling machine with means by which the different needles in the different sections of the fabric can be adjusted separately, although operated simultaneously; to provide an improved stripper for the needles in which vibration is largely avoided and to provide a machine for this purpose which will produce better work than has been done before.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings, in which Fig. 1 is a side elevation of a felting machine constructed in accordance with this invention;

Fig. 2 is a front elevation thereof;

Fig. 3 is a sectional view on the line 3-3 of Fig. 2;

Fig. 4 is a plan of the stripper and associated Fig. 5 is an end view looking in the direction of the arrow 5 in Fig. 1, showing the adjustment of the take-up mechanism.

This machine is constructed on lines similar to with certain improvements as will appear.

It comprises a frame 10 carrying an operating motor 11 which, through gearing, drives the main shaft 12. This shaft by means of bevel gearing the machine. The bevel gearing is shown as protected within two casings 15, one on each side of the machine. The casings 15 are provided with oil up to any desired level to keep the mechanism lubricated. Each shaft 14 is provided with a plurality of eccentrics 16 in the casings 15. Each eccentric is provided with an eccentric rod 1'7 having a turn-buckle adjustment 18.

It will be understood that these eccentrics and the top a pair of them operate a pin holding block 19. Each eccentric rod is provided with a forging or casting 20 at the top having an opening through it for receiving studs 21 projecting from These blocks slide up and down in ways 23 and the studs 21 project through guiding slots 24 in end frames 25.

From what has been said it will be seen that each block 19 can be adjusted independently of the other blocks and each end of each one independently of the other. The blocks can be arranged in any desired relationship to each other and if they get out of position it is very easy to adjust each one.

As shown in Fig. 3 each block 19 is provided prefper cent to J. Hawley 1930, Serial No. 487,015

erably with two rows of pins 22. These pins therefore, instead of being mounted on a single block as usual, are mounted in pairs of rows on a large number of blocks and adjustable independently of each other. come shortened, that block can be adjusted to compensate therefor Without changing the rest of the device.

As is usual, a stripping plate is employed for holding the fabric down while the pins are being pulled out. In this case the stripping plate consists of a series of longitudinal strips 27 arranged parallel with each other and extending along the frame under the stripping blocks. Instead of having these strips connected together by continuous strips, either transverse or angular, I provide cross strips 28 staggered from each other between each pair of longitudinal strips. In this way a shock or vibration is not transmitted through the stripper plate directly but is broken up. Therefore the vibrations are of shorter amplitude and the stripper plate stays in the desired position more accurately than has been the case heretofore. This stripper is provided with upwardly extending bars at its corners having slots and connected with the frame 25 of the machine by bolts 30. Thus the stripper can be adjusted vertically to take care of felts of different thicknesses.

On one of the shafts 14. there is an eccentric disc 32 having a diametrical screw33 provided with a nut 34 adapted to be moved along the screw by the turning thereof. This nut is connected by a link 35 with a swinging arm 36 which has a pawl 3'? engaging the teeth on the wheel 38 of the roll of the take-up mechanism. The usual pawl 39 operated by gravity is used for holding the wheel. This constitutes a take-up mechanism as will be obvious that is adjustable to provide for the proper feed.

In this way a fabric can be felted and the needles can be kept level by very simple adjustments while, if desired for the purpose of any irregularity, the different needles can be adjusted to different heights. The stripper holds the fabric down and is not capable of any such vibration as has been the case heretofore and is not likely to injure the needles from that cause. As will be seen from the description given the machine is built solidly and is very durable.

Although I have illustrated and described only one form of the invention I am aware of the fact that modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the If the pins on one block beclaim. Therefore I do n this respect but What I In a felting machine, frame, a motor carried th 5 by the motor, two shafts machine and at right angle shaft, means for operating the first named shaft, a p

ot Wish to be limited in do claim is:

the combination of a ereby, a shaft operated opposite'sides of the s to the first named the side shafts from air of casings at the GEORGE HARRIS COCHRANE.
