DRAWING FRAME.
In Letters Patent No. 1,351,076, issued to me, I have shown and described a combing machine in which the comb cylinders are given a regular constant rotation, Vbut I have found by experience that it is very desirable that the speed of rotation of the comb cylinder shall be variable, the more rapid part of its rotation being at a time when its clothing or teeth are passing under the rear detaching roll. When the last row of teeth have passed the detaching roll the s )eed of the cylinder should be slower until the first row of teeth again reach the detaching roll. I have shown and shall describe my improvement in connection with a double comber like that described in my said patent, but it will be evident to anyone skilled in the art that its improved features are equally applicable to a single comber or to other machines where such changes of speed are desirable. L v
My invention will be understood by reference to the drawings in which it is Vshown in its preferred form.
Figure 1 an elevation of one of the supporting frames of a machine embodying my invention in its preferred form, c0rrespondino` to Fig. 5 of my said patent.
Fig. 2 is a side elevation of a portion of such a machine including the frame, shown in Fig. 1 and certain of the frames shown in Figs. 2 and 2a of my said patent, the intermediate portions comprising the nipper frames, etc. being` broken away.
Fig. 3 is a plan view similar to Fig. 2, and
Fig. a is a detail to be described below.V
A, A1 are vertical members of the frame. The power shaft 1 is mounted as in said patentand carries a pinion 3 which engages the gear 31 on the shaft 8. On the shaft 8 is also a smaller gear 7 in mesh with a gear 2 on stud 21, which gear 2` is in mesh with a gear 6 which in turn is in mesh with a. gear 61. Gears 6 Vand 61 are each on jack shafts 6EL and 61a. Each of these jack shafts 6u and 61a carries an elliptical gear 62 and 62 and each of these elliptical gears is in mesh with a similar elliptical gear 64 and 6%21 on the shafts 63, 63a, respectively, corresponding to the shafts 63 of my said patent. These two pairs of elliptical gears 62 and 64 and 62xL and 64 are arranged in opposite relation to each other on their respective shafts so that the gears of each pair are always in'mesh. The elliptical gear 62a is the driving gear'of thesystem.
rlhe gears referred to as elliptical gears are in fact elliptical, each having a long and short axis varying the fraction of an inch in length so that their diiference cannot be distinguished in the drawing.V Theyv are also setveccentrically on their shafts. This description also applies to elliptical gears 31 and 631a referred to below.
As in my said patent, the comb cylinders are mounted-on these shafts 63, 63at and by the `use of elliptical gears arranged as shown power applied to the gear 6 from shaft 1 will turn the shafts 63, 63E and the comb cylinders will be given rotation atvariable speeds, one of. the combs being given'its rapid rotationv while the other is moving more slowly. YIt will also be seen from my said patent thatl in the machines operation while the nipper frames onone side of the machine are active, that is, are carrying the fleece to the detaching rolls, at the same moment the nipper frames on the other side of the machine vwill have dropped the fleece (see Fig. 3 of said patent). It is while the nippers are `active that rapid movement should be given to the cylinder combs in this machine; l'
Itis also necessary, however, in machines of this class that the draw box and cans, which `are to kreceive theY comber fleece or sliver, should be moved in .a regular, notV variable manner. In machines embodying .the invention of mv said patent, the draw box and cans are located in front of the end of the machine (see Fig. 1 of said patent where the shafts 63 are shown in section. indicating that the shafts 63 are extended for this purpose). To translate the variable movement given to the shafts 63, 63a so as to give a regular movement to the draw box and cans, I provide on the farther end of the driving shaft 63a of the elliptical gear system described, an elliptical gear 631 which is set with its long diameter at 180 degrees to the long diameter of the gear 641*l at the other end of the shaft. 641`is a sleeve mounted in the support A. about the shaft 63 and movable independently thereof. This sleeve carries a second elliptical gear 631 together with a bevel gear 65 in mesh with the bevel gear 66 on the draw box operating shaft 67. The draw boxes are mounted on brackets A2, A2 carried by the frame A1 andV ere not. shown as they may he of any `Well known construction.
