DETACHING ROLL-MOTION FOR COMBING-MACHINES.
Original application led October 7, 1918, Serial No. 257,089.Y
To all tc/om it may concern:
Be it known that I, HARRY TUNSTALL, a subject of George V, King of Great Britain and Ireland, residing in Fairhaven, in the county of Bristol and State of Massachusetts, have invented a new and useful Improvement in Detaching Roll-Motions for Combinglvlaohines, of which the following is a specification.
In my application Serial No. 257,089 I have described in full a combing machine including the mechanism forming the subject-matter of this application, which is a division of the application above specied.
The main purpose of this mechanism is to give to the lower steel rolls a progressive oscillatory movement whereby with the assistance of the top or leather roll the fiber 4 may be properly treated, and to give to the leather roll a motion around the axis of the steel roll, e. the roll nearest the comb, so that it may grasp the tuft at the proper time and assist roperly inthe piecing up of the sliver. I eretofore'the necessary motions have been given to these parts by cams suitably cut and mounted. But I have found by experience that cams, although usual, are undesirable in machinery of this class, because the fiber is short and delicate and any slight change in the movement of the parts operating upon it such as might be due to the wearing of the cam, changes the character of the product of the machine, and the wearing of the cams can only be remedied at considerable expense.
' y invention will be understood by reference to the drawings in which it is shown in its preferred form, only so much of the whole machine being shown as is necessary to indicate the mode of operation of the parts referred to.
Figure 1 is a front elevation showing the detaching roll,y its top or leather-covered roll, and the means of applying power thereto.
Fig. 2 is a section on line 22 of Fig. 1.
Fig. 3 is a detailshowing the mounting of the top or leather-covered roll.
ig. 4 is an enlarged Section on line 4-4 of Fig. 1, showing the clutch-operating mechanism.
Fig. 5 is a longitudinal section of the clutch, and
Fig. 6 is a front elevation thereof.
Specification of Letters Patent.
Patented Oct. 18, 1921. Divided and this application led October Serial No. 334,227.
is to give the and is moved thereby. It and the top leather roll 86 receive the tuft. The clutch will be understood from Figs. 5 and 6.
Thelgear 114 is suitably supported and is atec A crank disk 1141 shaft with gear 114 and carries a crank pin 120 which is connected by the link 115 to a piu 116, which connects together disks 117 and 118 forming part of the clutch. 119 are other pins which`connect these disks. location of the pin of its movement is greater of movement of the pin 120 so that the rotation of the gear 114 will reciprocate the link 115 and Aoscillate the disks and the parts connected thereto.
On the shaft 921 is a sleeve 121 which carries fast thereon the ratchets 122 and 123. As shown, they are integral therewith and separated from each other to allow proper movement to the link 115. The disk 117 is mounted to turn freely on sleeve 121. A disk 124, of smaller diameter than disk 117, has ahub 121, which is adjustably fixed on shaft 921. The disk 124 is cut away as at 125 to expose for a portion of its Aon the ratchet 123, while the periphery of the rest of the disk 124 extends slightly beyond the radius of the ratchet teeth on ratchet 123. On the hub 121a is the which is free to turn thereon.
The teeth of ratchets 122 and 123 point in opposite directions, and'pawls 126 and 127 are provided, one of which engages ratchet 122 and the other the ratchet 123.
The pawl 127 is wider than the pawl 126 so as to overlap the disk 124. These pawls disk 118,
are held to their work by springs 128 sup ported on sleeve 1281 mounted on one of the pins 119 connecting the disks 117 and 118.
It will be seen thereforethat when the link 115 lifts (see Fig. 4), it moves the pawls, and the pawl 127 engages the ratchet 123 and pushes it in the direction of the arrow, the ratchet carrying with the sleeve 121 and the gear to the'sleeve 121.
When the link 115 is pulled downward it reverses the movement of the pawls and consequently the pawl 126 engages an moves the ratchet h it 92, which is keyed 122 and carries wit the sleeve 121 and gear 92V and also the pawl 127, which drags over the teeth of ratchet 123. But when the pawl 127 reaches the part of the disk 124 having the greater diameter it rides up onto it (see Fig. 4), Y so that when the link rises again and the movement of the pin 116 is reversed, the pawl 127 moves first along the smooth surface of the disk 124 until it drops into the teeth and gives motion to the ratchet, sleeve and gear. This disk 124 yis adjustable on shaft 921 so that it will engage the pawl 127 at any desired time in its path of operation.
The result of this construction and operation is to give to the steel rolls an intermittent oscillating movement which is, however, progressive in that its movement in one direction is longer than its movement in the other,
so that the fibers being properlyV retracted will alsobe properly fed progressively forward in the piecing-up operation,.and the amount of retraction may beA adjusted according to the length V`Yof they ber by adjusting'the positionofthe disk 124and-conse quently the time of engagement of the pawl 127 with the ratchet 123.
The position of the crank pin'120 may be adjusted in its slot in the crank `disk 1141 to change the position of. the link 115 so as to adjust its throw and hence the path of oscillation of the parts connected tol its upper end.V
Power is applied to give theV desired movement of the leather roll 86 as follows: rI`he shaft 8 which is suitably-supplied with power from the power shaft (not shown) by means of the gear 7, etc. (see my carries a disk 105, which is connected by a crank pin 106 and a link 107 to a rocker arm 108 by an 'adjustableslotted connection 109, the rocker arm. 108 being attached to thc shaft 103. 93 is the bearing for one end of the leather roll 86 (the other endof the roll being provided with a similar bearing and mechanism), and it is mounted on the end of the spring 94,.the rear end of which engages the pin 95 on arm 97. A lever 96, also mounted-on the 4arm 97 may be-used togadjust the tension of this spring 94 (see Fig. 3). The arm 97 is mounted on a rockit the ratchet 122,
Ycarrying oppositely-disposed ratchets,
said application), l
n The operation and the theory of the above mechanism will be understood by reference to my above application. ,I do not mean to limit ymyself to the exactV mechanism above described, as it will be understood by Athose skilledin theart that the details may be changed without departing from the spirit of my invention. j described one side of the machine. It-will be understood that so far as is necessary the vother side of the machine is provided with similar bearings, etc.
