May 23, 1950 w. NAEGELI PRESSURE DEVICE FOR DRAWING FRAMES Filed May 5, 1948 Patented May 23, I950 2,508,964 i UNITED STATES PATENT] OFFICE 2,508,964 rnassmm DEVICE ron nmwnzo' rams Application May 5, 1948, Serial No. 25,293
InSwi tzerland March 19, 1947 8 Claims. (Cl. 19-135) This invention relates to improvements in pressure devices for the roll heads in drawing frames, comprising a weighting arm pivoted on a pin to the frame and provided with holders which carry the top rolls.
In conventional cotton type drawing frames, the load is transmitted onto the top rolls through a stirrup-and-lever system which, disadvantageously, is arranged in the rear or in front of the roll head. Such known arrangement renders the operation of the frame more difllcult, particularly the mounting and removal of the lower rotary roll clearers. Further, the weights or springs and the stirrup-and-lever system of such known pressure devices easily soil through the deposit of dust and fly, which may cause disturbances in the operation of the frame.
In order to avoid such inconveniencies' and disadvantages of known weighting arrangements, the pressure device according to the present invention is disposed in or on the support pivot pin of the weighting arm and substantially intermediate of the lateral legs of the said arm which has two side walls and connecting means therebetween.
Elastic elements such as springs or a fluid pressure hose supported by said pin and subject to pneumatic or hydraulic pressure, may be provided for producing the weighting load. The latter suitably may act on a bearing pin of a swingable arm pivoted to the weighting arm and,
through the said pin, on the weighting arm and its holders and top rolls. Again, the spring means may be supported, when the top rolls are not loaded, under preliminary tension on a stud connected to the said pin.
The present invention is shown in various forms in the accompanying drawing, in which Fig. 1 shows a first form in side elevation and partly in section,
Fig. 2 a second form in a similar view,
Fig. 3 a top plan view, partly in section, of Fig. 2, and
Fig. 4 represents a third form in a view similar to Fig. 1.
In the first form (Fig. 1), the front portion of the weighting arm I is composed of side walls and a connecting wall extending laterally from the upper edges of the side walls and, thus, is U-shaped in cross-section, while its rear portion is formed by two vertical walls only. The latter are bored for reception of a support pin 2 which extends the entire length of the frame. Two holding plates 3, which are disposed intermediate of the said vertical wall and each of which is provided with a nose 4, are fixedly connected to the pin 2 and secure the arm I against lateral displacement on pin 2. The said two plates 3 are interconnected by or integral with a saddle 5 which is semi-cylindrical and is lodged on pin 2.
The said saddle, however, could be a full or I closed ring. Besides the plates 3, the holders 6, l and 8 of the top rolls A, B and C also are disposed intermediate of the two vertical walls of arm, I. A swingable arm 9 is pivoted on a pin III to arm I, and its rear portion is shaped substantially as a semi-circular hollow body having side walls. A detent roller II is rotatably mounted on a pin secured to the two side walls of the said rear portion of swingable arm 8. The said side walls are each provided with a beak-like projection I2;
In Fig. 1, a spring-wire I3, bent off at various points, is provided for producing the weighting load or pressure. One end portion of the spring I3 extends through a transverse bore of pin 2 and, at the same time, an aperture in the saddle 5 of the two discs 3, thus locating the latter on pin 2. The free end of spring wire I3, which permanently is subject to a certain preliminary tension, abuts against a stop stud I4 secured to the holding discs 3 when the swingable arm 9 has been swung upward and when the top rolls A-C of the drawing head thus are not weighted.
In the example shown in Figs. 2 and 3, one leg of a torsion rod I5, which is bent oil at various points, is inserted into a longitudinal groove I6 of the pin 2; the one end portion of rod I5 being anchored in a cross bore I! of pin 2. When the swingable arm 9 has been swung upward, the rod I5 is subject to a. preliminary torsion through a stop stud I8 secured to the two holding plates 3'.
In the third form (Fig. 4) the pin 2' is tubular and houses a fluid pressure hose I9 which extends over the entire transverse width of the frame and is subject to pneumatic or hydraulic pressure. One end' of a lever 20, fulcrumed on a pin 2I secured to the two holding plates 3, abuts against a protective or bearing plate 22 supported on the-pressure hose I9; said lever projecting through a slot provided in the wall or the, tubular pin 2'. A stationary stop 23 provided inside the latter limits the rocking move-.
ment of lever 20.
In all the forms of invention described and shown, the top rolls A-C rest, in the nonweighted state of arm I, on the bottom rolls D--F under the dead weight of the pressure device; the swingable arm 9 being slightly raised. In the first two examples (Figs. 1-3), the free ends of the springs I3, I5, which are prestressed, then abut against thestop studs I4 and I8 respectively. In the third example (Fig. 4), the lever 20 then is urged upward against stop 23 through the pressure hose I9. When depressing the swingable arm 9 onto arm I, which depressing may be easily done by virtue of the relatively long leverage of arm 9, the detent roller II is engaged by the adjacent bent free portion of spring I3 or I5, or of lever 20 respectively, whereaeoaoea upon the resilience of the said springs or the force engaging the lever 20 through hose II, is directly transmitted onto the arm I through the lid roller I l. The top rolls A-C secured to arm I, thus are pressed down against their appurtenant bottom rolls D-F. When it is desired to relieve or unload the drawing head, swingable arm I is simply raised. The springs l3, I! then are relieved, when the rollers ll roll on the bent spring portions, until the stop studs l4, I! prevent a further relief. The lever 20, during such relieving operation, is rocked until it abuts against the stationary stop 23. In such relief position, the swingable arm 8 and weighting arm I are disengaged from the pressure-producing means.
It also is possible, by correspondingly swinging the arm 9 upward. to also swing upward the arm i together with the holders 6-8, in that the two lateral noses 25 of arm 9 strike against a cross rib 24 provided on arm I, so that the latter then follows arm 9. In the raised position of the arms I, I shown in Fig. 1 by dash-and-dot lines, the
' beak-like projections I! of arm 9 are engaged to the rear of'the noses 4 of the holding-discs 3, whereby the arm 9 is held in the respective position, as is also the arm-l with the aid of pivot pin 10.
The load may be easily and readily applied and removed, by means of the arrangement described, by correspondingly manipulating the arm 9. The weighting-arrangement according to my present invention affords a well set, uniform appearance to the drawing frame, and substantially facilitates its operation, since levers and stirrups are avoided in front, intermediate and in the rear of the drawing rolls. Further advantages of the form of invention shown in Fig. 4 are that the pressure of the top rolls against the bottom rolls may be readily adapted to the nature of the fibrous material to be worked by varying the pressure of the fluid in hose l9, and that all the drawing heads of the frame may be loaded and unloaded from a central point by raising or low ering the pressure of said fluid.
