Specification of Letters Patent.
Application filed. August 5, 1913.

Serial No. 783,037.
T 0 all whom it may concern Be it known that I, JAMES DRONSFIELD, a subject of the King of Great Britain and Ireland, residing at the Atlas Works, Oldham, in the county of Lancaster, England,
card-grinding-machine maker, have invented new and useful Improvements in Means for Dressing or Resetting and Grinding the Teeth of Licker-in or Taker-in Rollers Used in CarclingEngines, of which the following is a specification.
At the present time no serious attempt is made to dress or re-set the teeth on lickerin or taker-in rollers, used in carding engines, although such teeth are liable to be displaced or bent or damaged during working, and, as a consequence, the licker-in or taker-in roller is rendered less effective in action.
The object I have in view, is to arrange for the periodical dressing or re-setting and grinding of the teeth upon such rollers by providing a machine for this express purpose. To this end, and, according to my invention, I construct a machine which will more or less automatically carry out the desired dressing or re-setting, and, if necessary grinding operations whereby the teeth can also be ground in the same machine. The machine is adapted to receive and support the licker-in roller while being acted upon.
The construction of the new machine for the purpose in view, is hereafter fully described and illustrated by the attached drawings.
Figure 1 shows a general end elevation of the machine. Fig. l is a detail plan of one of the swivel holding down caps. Figs. 2 and 2 show a longitudinal elevation of the machine with certain parts omitted. Fig. 3 is a separate detail view of the base part of the adjustable clamp. Fig. 4L is a plan of Fig. 8. Fig. 5 shows a plan of the upper part of the adjustable clamp. Fig. 6 is an enlarged detail view of the movable tool holder. Fig. 7 is a plan of Fig. 6. Figs. 8 and 9 show (by the full lines) side and edge views of one of the dressing blades or thin bars, a number of such being clamped together to form the complete tool.
The machine illustrated, consists of end standards or supports, 1, 1 upon which, a longitudinal bed casting 2 is placed and there secured, and, upon the horizontal stretch of this bed casting 2, I apply brackets 8, 3. These brackets 3, 3 are preferably adjustable one to the other along planed ways as shown. They have steps or bearings 4 to take the shaft 5 of the lickerin roller, which roller is indicated by dotted lines and marked 5. Swivel holding down caps, such as those marked. 6, and held by milled headed screws 7 may be used as the retaining means for the shaft of the licker-in roller. The detail Fig. 1* shows one of such caps 7 separately and in plan view.
Formed with or attached to the bed casting 2 is a longitudinal slide or tool holder bed 8, the face and edges of which are planed, and this stands at an angle from the horizontal stretch of the bed casting 2. This horizontal slide or tool holder bed 8 is most conveniently formed with its upper edge 9 as a V edge, and, with its other edge 10 as a right-angle edge. Upon this longitudinal slide or tool holder bed 8 I mount a movable tool holder 11 (see Figs. 1, 6 and 7) which is adapted to be traversed from end to end of the aforesaid bed 8. This movable tool holder 11 consists of a casting (as shown) with applied edge bar 12, such casting being fashioned to engage the edges of the aforesaid bed 8 and to be movable thereon. The movable tool holder 11 has planed ways 13 or slide faces to guide a base casting 14:, which, along with the cover plate casting 15 forms the tool clamping means. This casting 14 together with its cover plate 15 can be adjusted toward and from the licker-in roller 5, that is, at right angles to the'direction of traverse of the movable tool holder.
The adjustment can be readily efi'ected by means of a screw 16 which engages the slidable base casting 14, the screw 16 being carried by a block 17 pivoted at 18 to the movable tool holder 11. By providing a screw such as that shown at 19 and passing through the clamp to bear on the upper face of the movable tool holder 11 (or by an equivalent device) the entire tool clamp can be adjusted angularly about the pivot 18 and so with respect to the teeth of the licker-in roller.
The tool to effect the dressing or re-setting separately shown by the Figs. 8 and 9. These blades or thin bars 20 are ground away at the forward portion to leave a reduced thickness as at 21. The requisite number of these blades or thin bars 20 are placed so as to abut together and to stand edge-on. The whole group are held clamped in close association by bolts 22 passed through the holes 23. When a number of such blades or thin bars 20 are so bound together, a slot or gap is left between each contiguous blade or thin bar, which slots or gaps, the teeth or the licker-in roller occupy when the tool is at work and so the narrow parts of said blades or thin bars lie between the ranks of the teeth on the licker-in roller. At any time after the desired number of blades or thin bars 20 have been secured together side by side with the bolts and nuts 22, the tool itself is complete and ready, and can be easily introduced in place in the clamp 14:, 15, on slackening back the studs 15*. The studs 14* in the cover plate 15 merely serve to bind the cover plate 15 to the casting 14:. On firmly tightening the studs 15 the complete tool 20 is thereby firmly clamped and held and ready for its work in the clamp 14, 15.
The machine has a first motion shaft 24 with fast and loose pulleys 25, and the licker-in roller 5 can be driven for dressing or re-setting purposes from a small pulley 26 on a stud shaft 27 driven by chain gear 28, 29, 30 from the first motion shaft 24:, or in other obvious fashion. In the rear of the machine, and upon the same standards 1, 1, I apply brackets 31, 31, to support means to carry a traversing grinder and I use a traversing grinder 32, carried on the shell 33, and whereby the licker-in roller 5 can be ground as well as dressed or re-set in the machine. shell and its concentric screw-threaded shaft inclosed in the shell 33 are carried in such manner as permits of all necessary adjust ments being made by the hand-wheel 34, which hand-wheel 3d operates worm and toothed gear as shown whereby the traversing grinder 32 can be set angularly toward and from the licker-in roller 5 in manner indicated. 7
The means for adjusting the traversing grinder forms no part of this present invention the arrangement shown being similar to what is employed by us in other machines where a traversing grinder is used with adjustable means to support same. The tube or shell 33 carrying the traversing grinder 32 is shown as being driven by a belt 35 extending between the small pulley 36 and the large pulley 37 on the first motion shaft 24. This tube or shell 33 actuated by the pulley 36 drives the diiferential motion in the box 38 which in turn actuates the double'threaded screwed shaft 39 inclosed This traversing grinder in the tube or shell 33 the complete arrangement being an ordinary standard traversing grinder group of the wheel grinder type.
I may provide means which permit of the licker in roller being driven at a difierent speed when grinding, as, for instance, I may in that case drive the licker-in roller from a small pulley on the end of the first motion shaft.
To effect the dressing or resetting of a licker-in roller, the said roller is introduced into the bearings 4: and the built-up tool 20 carried by its clamp has its reduced extremities put into engagement with the teeth on the licker-in roller, and so as the latter revolves, the blades or thin bars dress, straighten, and restore the teeth as the tool box 11 is traversed from one end of the licker-in roller to the other. The traverse, along the length of the licker-in roller, is performed automatically and the operation of dressing or resetting the teeth is uniform and is accomplished in a very satisfactory manner.
It is obvious that the tool clamping device can have two necessary adjustments given with regard to a licker-in roller.
I may considerably vary the details set forth so long as I produce a machine of the kind indicated to do the particular class of work herein related.
I declare that what I claim is:
1. A power actuated machine for dressing or straightening the teeth of licker-in rollers, comprising means to support said roller, means to rotate said roller, a tool holder bed, a movable tool holder mechanically moved on said bed, a clamp fitting same, substantially flat tools in said clamp capable of sinking between or engaging between the teeth on the roller, engagement of the flat tools between the teeth on said roller effecting automatic traverse and uniform setting without manual attention as herein related.
2. A machine for the indicated purpose comprising supports for the licker-in roller and means to drive said roller and having a tool holder bed with which is combined a tool holder device, a clamp adjustable therein, and a dressing tool for the clamp, and means to adjust the clamp to the licker-in roller substantially as described.
