INK-GRINDER-ADJ'USTING ATTACHMENT.

Application filed November 12, 1926. Serial No. 147,879.

My invention relates to adjusting mechanismfor ink grinders, and more particularly to an attachment for adjusting roller mills.

Under the present method of adjusting the front roll of an ink grinding mill, each of the ends is moved independentlv from the other, thus consuming considerable time in making the proper adjustment in order to secure the required fineness of the product.

The principal object of my invention is to so connect the adjusting means that all adjustments may be made from one end of the mill.

A further object is to so place the controls that the operator can simultaneously reach one with either hand.

These objects, and other advantageous ends which will be described hereinafter, -I attain in the following manner, reference being which Figure 1 is a plan view of an ink grinding mill on which my attachment has been installed, 1

Figure 2 is a front elevation of the shown in Figure 1,

Figure 3 is a view taken on line 33 of Figure 2, some of the parts being omitted for the sake of simplicity,

Figure 4 is a fragmentary front view, some of the parts being omitted for the sake of simplicity,

. Figure 5 is a cross sectional view taken on at line 55 of Figure 4, and

Figure 6 is a cross sectional view taken on line 6--6 of Figure 4,

Figures 3, 4, 5 and 6 are drawn to a larger scale than Figures 1 and 2.

Referring 'to the drawings, 7 indicates the frame of a roller mill, 8 a bracket attached to one end of the frame, 9, 10 and 11- the mill grinding rolls which are actuated by means of belts engaging pulleys 12 and transmit- 4 tin rotation through the train of gears 13,

an 14 represents the discharge apron. The

above enumerated parts are. the principal elements of a well known roller type grinding mill and will not be further described as they form no part of my invention.

15 and 15 represent the adjustable bearings in which the front roll is mounted. Engaging the front side of the bearing 15 tlfirou h swivel connection 14 is a screw 16, t r

ed through a block 17 secured to the hadto the accompanying drawings frame 7,. and having a helical gear 18 mounted near its center. The screw is mounted in a bearing 19 which is secured to the frame of the mill in an suitable manner. A screw 20, having a elical gear 18 mounted thereon and which is threaded through a block 17 a secured to the frame 7, is bored throughout its length and has a secondary screw 21 rotatably mounted therein with its inner end engaging bearing 15 through swivel connection 14. An enlarged threaded portion 22, of the screw 21, engages threads in a counter-bored portion 23- of the screw 20. The screw 20 is-mounted in a bearing 24 secured to the frame of the roller mill in any suitable manner. Immediately below the gears 18 and 18, on' the screws 16 and 20, is mounted a longitudinal shpft 25 having helical gears 26 and 26 rig-idly secured thereto and meshing with thegears 18 and 18 respectively. The shaft is held against longitudinal movement by collars 27 and 27" secured on either side of the bearings 19 and 24. A hand-wheel 28 is secured on one end of the shaft 25 and another hand-wheel 29 is secured on the screw 21.

- B turning hand-whell 28, attached to sha 25, the screws 1 6.and 20 will be rotated by the action of the helical gears 18 and 26, attached to the screws and shaft respectively. As the screws are threaded through the blocks 7 and 7* attached to the mill frame with the inner end of screw 16 engaging roll bearing 15 and the end ofsecondary screw 21 engaging roll bearing 15, pressure between the rolls may be increased or decreased asldesired. When it is discovered that the rolls are not bearing evenly throughout their lengths, adjustment is. 95 made by turning hand-wheel 29 attached to screw 21. The hand-wheels are located adjacent one another so that the operator may grasp one in either hand and instantly make accurate adjustments.

While I have described my invention as taking a particular form, it will be understood that the various parts may be changed without departing from the spirit thereof, and hence I do not limit myself to the pre- 105 cise construction set forth, but consider that I am at liberty to make such changes and alterations as fairl come within the scope of the appended c aims.

Having thus described my invention, whet 110v 'I claim as new and desire to secure by Letters Patent is 1. In combination with a color grindin machine having parallel rolls, one of sai rolls being mounted on adjustable bearings, means at either end of said roll operable responsive to a sin 1e control for simultaneously moving sai bearings to adjust said roll with respect to the other rolls, and means associated with one of said adjustable bearings and passing through said first means thereat adapted to adjust said hearing independently of the other of said bear- 2. In combination with a color grindin machine having parallel rolls, one of sai rolls being mounted on adjustable bearings, a threaded member at either end of said roll passing through a stationary block of the machine and swiveled to said bearings, a shaft having means thereon and a control for operatingsaid means to adjust said members simultaneously, and threaded means passin through one of said blocks and the mem r associated therewith for moan-r adjusting only the hearing at said end of the machine.

3. In combination with a color grinding machine, parallel rolls, one of said rolls being mounted on adjustable bearin a threaded inner member at each end 0? said roll passing throu h individual blocks thereat, an outer mem r removably secured to each of said inner members, a gear on each of said outer members, a shaft having gears thereon, whereby upon the actuation of a single control, said shaft is adapted to actuate said ears and members, one of said inner mem rs being swiveled to one of said adjustable bearings, a threaded rod passin through the other inner member and swivele to the other adjustable bearing, said rod bein adapted to adjust said bearing indepen ently of the other bearing, both said bearings being adapted to be adjusted simultaneously and equally by a movement of the shaft.

In testimony whereof I have signed my name to tliisspecification.

GUSTAV A. VASEL.
