Application ledvJunie 1, 1914. Serial No. 842,059.

To all whom t may concern.' f y Be it known that I, WILLIAM H. WAGNER, a citizen of the UnitedStates, residing at Burlington, in the county of Racine and State of Wisconsin, have invented certain new and useful Improvements in Needling- Machines, of which the following is aspeciication, reference belng had to the accompanying drawing, formlng a part thereof.

his invention relates to needling inachines and the objects of the invention arel to lmprove needling machines in the manner to be hereinafter described and claimed.

Referring to the drawings which accompany this s eciiication and form a part hereof, on wliich drawings the same reference characters are used to designate. the same parts wherever #they may appear in each of the several views, and which drawings illustrate an embodiment of this invention, Figure l is an elevation of one side of the machine; Fig. 2 is an elevation of the other side of the machine, parts being broken away and parts being shown in section; and ig. 3 is an elevation of the feeding end of the machine, parts being broken away.

Referring to the drawings, the reference numeral 1 designates the frame of the machine on which the mechanism is assembled. The frame is ted needle be s 2 and 3 which are positioned between guides formed on the frame. Each needle bed is supported by screwthreaded rods, preferably by a rod at each end, 4

which in turn are supported by the worm Wheels 5 which are screwthreaded to engage therods. Worm shafts 6 and 7 are provided for the worm wheels and screwthreaded rods of each needle bed so that by rotating the said shafts the needle beds can be raised or lowered to suit the thiclmess of the material -to be operated upon. To permit 'the machine to be run at high speed the needle beams 8 and 9 are built up from steel in the form of rectangular tubes and are counterbalanced by springs 10, 11, l2 and 13. They are also strengthened The needle beams are movable both vertically and longitudinally within guides formed on the frame. I have illustrated the machine as provided with two needle beds and two needle beams and I prefer that the two sets of needles carried by the needle beams shall not enter the material at the same time as by such an arrangement I can better counterbalance the machine and serovided with adjustable, slot-.

tion wheel 41 which 28 and is movable n shaft 40 toward or v and the ratchet by trusses 14 and 15.l

cure more complete uniformityof feed of the material. Two drive shafts 16 and 17 are located at opposite sides of the machine. Drive shaft 16 is provided .with the fast pulley 18, loose pulley 19, chain wheel 20, and hand Wheel 21. Drive shaft 17 is provided with chain wheel 22 and is driven froml shaft 16 by chain 23 which runs over the tightener 24 and is inclosed in the casing 25. Drive shaft 17 is also provided with a hand wheel 26 and is illustrated as provided with a pulley 27 for its -iiy wheel effect and with the friction disk 28. Drive shaft 16 is provided with the counterbalanced eccentrics 29 and 30 which are laced ninety degrees apart and drive sha 17 is provided with the counterbalanced 'eccentrics 31 and 32 which are also placed ninety degrees apart and the eccentrics on the two shafts are so placed that each needle beam is parallel with the needle bed with which it operates. The eccentrios are connected with the needle beams by the eccentric rods 33, 34, 35 and 36. The hand wheels 21 and 26 are for turning the machine by hand when desirable or necessary as, for example, to lift a set of needles out of the material being operated upon. Levers 37 and 38 on opposite sides of the machine are connected with the belt shifter l39 for starting and stopping the machine.

The shaft 40 is driven from shaft 17 by a speedchanging device which, as illustrated, comprises the friction disk 28 and the friccontacts with the disk away from the center of disk 28 in the ordinary manner, the shipping bar 42 being held in any desired position of adiustment by the screw clamp. 43. Shaft 40 is provided with the'miterwheel 44 which meshes with the miter' wheel 45`on shaft 46 which is also provided withA the worm 47 which meshes with the worm wheel 48 on shaft 49. Worm Wheel 48 is loose on shaft 49 but is adapted to revolve the shaft by means of the pawl wheel 51. A sprocket wheel 52 on shaft 49 drives the drawin roller 53 by means of the chain 54 and the sprocket Wheel 55. Shaft 49 carries, at the opposite side of the machine, a. bevel gear 56 and a sprocket wheel 57. Sprocket wheel 57 drives sprocket wheel 58 by the chain 59. Sprocket wheel 60 and sprocket wheel 58 are united and carried by the stud 6l and sprocket wheel 60 drives sprocket wheel 62 and conveyer roller 63 by chain 64 which runs over the supporting conveyer 66 is supported by rollers 63 and 67 and is. the feeding member for the felt which is wound into a roll 68 on a spindle 69 in the ordinary manner. The bevel gear 56 meshes with and drives a bevel gear 70 secured to shaft 71 and this shaft is supplied with two eccentrics 72 and 73 which rock the bell cranks 74 and 75 by means of the connecting rods 76 and 77. The bell cranks 74 and 75 are pivoted to the frame 1 and their downwardly extending ends terminate in knuckles 78 which engage with slides 79 retained within guides in the needle beams. On the opposite side of the machine two links 8O and 81 are pivoted to the frame 1 in line with the pivots of the bell cranks 74 and 75 and their Alower ends terminate in knuckles which engage with slides retained within' guides in the needle beams in the same manner as the downwardly extending ends of the bell cranks. This construction permits the needle bea-ms to be reciprocated up and down by the eccentric rods 33, 84, 35 and 36 and to be moved longitudinally by the eccentrics' 72 and 7 8.

A weight roller 82 grips the material to the drawing roller 53.

The needles 83 are the ordinary barbed needles used with machines of this general character and are assembled on strips of Wood 84 or other suitable material and are removably clamped under the needle bea-ms by clamps 85 which are provided with elongated slots 86 through which projects a bolt 87 provided with a nut 88 and a spring 89 between the nut and the clamp. By loosening the nut the clamp may be from the needle beam so that its inturned lower end will clear the strip of wood to which the needles are secured and then it may be pushed up out of the way with its lower end against the side of the spring will hold it in this position.'

The function of the machine is to needle fabrics as, for example, to unite a loosely felted material to a stay of woven material such as burlap, for example. The burlap is designated by the reference numeral 90, the felted material by the reference numeral 68, and the fabric produced by needling them together is designated by the reference nu meral 91. The burlap is led between rollers 92 and 93,' over roller 94 and over needle idler 65. The slat swung awayl the needle beam and bed 2. The felted material is led over needle bed 2 on top of the burlap and the fabric is then led under roller 95, over needle bed 3, under roller 96, over roller 97 and under roller 98 to the drawing roller 53 which is positively driven by the chain 54 and the drivingr mechanism The feed is continuous but when the needles are in the fabric it is, of course, stopped but the stretch of the fabric permits the continuous feed with-the intermittent stopping of the fabric by the needles. rl`he change speed mechanism permits the feed to be changed to suit different fabrics. The mechanism for longitudinally reciprocating the needle beams permits of the machine being run at high speed without skipping and without danger of accidents.

In needling the average cloth, or material, the needle beams 8 and 9 make about twenty vertical reciprocations to one horizontal reciprocation but this proportion is change able. Each of the needle beams 8 and 9 makes a complete vertical reciprocation .for every revolution of the shafts 16 and 17. Each of the needle beams 8 and 9 makes a complete horizontal reciprocation for every revolution of the shaft 71. The shaft 71 is driven from shaft 17 by the friction disk 28, friction wheel 41, shaft 40, Initer wheels 44 and 45, shaft 46, worm 47, worm wheel 48, shaft 49, and bevel gears 56 and 70, which constitute speed reducing mechanism. The actual differences between the speeds of rotation of the shafts 17 and 71 can be varied by shifting the friction wheel 41 either to ward or away from the center of the fric tion disk 28.

What is claimed is:

In a needling machine, the combination with two needle beams of counterbalancing springs supporting the needle beams, and shafts provided with eccentric mechanism for reciprocating the needle beams, the eccentric mechanism for one needle beam being set ninety degrees in advance of the eccentric mechanism for the. other needle beam.

In witness whereof I hereto affix my signature in presence of two witnesses.
