SPECIFICATION forming part of Letters Patent No. 333.340, dated December 29,1885.
Application filed May 6, 1885. Serial No. 164,568.
against a second toothed blade or plate,which is usually stationary.
The invention,while applicable to shearing purposes and to tonsorial use, as in trimming or cutting the hair on the human head, is more particularly designed for horse-clipping pur- 7 poses, and it Will here be described more especially with reference to such use.
In power-machines of this description the two toothed blades or platesthat is, both the stationary and reciprocating plates have heretofore had a fixed transverse relation to the handle by which the machine is manipulated over the surface to be clipped,and to the frame which carries the gearing for reciprocating the one plate.
My invention consists in a swiveling connection of the stationary cutting-plate and certain connection with its gearing of the reciprocating plate, whereby both plates may be swiveled to occupy different transverse positions or angles relatively to the handle of the machine and frame or box which carries the gearing without interfering with the motion of the latter, thereby giving increased facility for manipulating the machine, to adapt the cutters to work over different parts or surfaces and in different directions as regards the out.
The invention likewise includes certain means for taking up the wear of the working parts and avoiding lost motion in the cutter, so as to insure its perfect operation at all times.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.
Figure 1 represents a longitudinal section of a power-machine, suitable for clipping horses, embodying my invention; Fig. 2, a sectional View on the line x w in Fig. 1 of the same in part.
(Model A is the handle by which the machine is manipulated over the limbs or body of the animal, and B the box or frame which carries the toothed cutting-plates O D and the gearing by which the reciprocating toothed cuttingplate D is operated.
E is the operating rotating shaft, arranged to pass longitudinally through the handle A, and which is connected withthe main or counter driving-shaft by the usual spiral-spring coupling, G, to give the necessary driving or working flexibility to the instrument, so far as its manipulation over the surfaces to be clipped is concerned; but instead of said spring-coupling being rigidly or permanently attached to the shafts which it connects it is loosely slipped over the end of each or either shaft and engaged therewith by simply turning it and causing its end spirals to receive within them a stud, b, on the shaft. This mode of engaging the spiral-spring coupling with its shaft or shafts not only provides for the ready engagement and disengagement of said coupling, but also admits of either a right or left hand spring being used to accommodate it to a main or counter driving-shaft rotating either to the right or to the left, thus adapting the implement to be worked from shafts moving in reverse directions, which will be found a great convenience.
The operating-shaft E communicates the necessary reciprocating motion to the toothed clipping-bar D by means of a bevel-wheel, 0, arranged to engage with a like wheel, d, on a spindle, H, that has its bearings in the box or frame B. On the inner end of the spindle H is a crank, f, that serves, by its connection through a link or connecting rod or bar, 9, with a lever, h, to give the necessary reciproeating motion to the bar or plate D. Such are the ordinary means of reciprocating the cutting-plate D, that is held to its bearing on the stationary cutting-plate O and guided in a straight line or course thereon in the usual or any suitable manner. Instead,however,of the IOO clipping bars or plates will give an enlarged versatility or flexibility to the implement,and enable it to be worked over or applied to different parts of the animal with greater freedom, thus extending the manipulating capacity of theimplement,inasmuch as the clipping-plates -may be set to work at different angles relatively to the handle A and box or frame B. To provide for this swiveling adjustment of the plates 0 D, the stationary plate 0, on which the reciprocating plate D is fitted to work, is attached by a screw or other pivot, '11, in the same axial line as the spindle H to the box or frame B. This admits of the clipping-plates being swiveled, as required, without interfering with the gearing or operating devices of the reciprocating plate.
It is important that the cutting-teeth of the reciprocating plate D should at all times have a full stroke over the teeth of the stationary plate 0, and as this is liable to be interfered with by lost motion consequent on the wear of the reciprocating devices, I provide for increasing, when necessary, the length of the stroke of the crank f by connecting the bar 9 with it through a slot, 7c, and nut Z,- or such adjustable connection maybe applied to either end of the bar g-that is, either to the crank and bar, as shown, or to the bar 9 and lever h-so as to give the necessary stroke to said lever.
Having thus fully described myinvention, I claim as new and desire to secure by'Letters Patentsaid box or frame and handle of the implement, substantially as specified.
2. The combination of the operating-shaft E, the handle A, the box or frame B, the gears c d, the spindle H, the crank f, the connecting-rod g, the lever h, the reciprocating cutting-plate D, the stationary cutting-plate '0, and the pivot i, essentially as shown and scribed.
3. The combination, with the toothed eutting-plates O D, of the lever h, the crank f, having a slot, is, in it, the nut Z, and theconnecting-rod g, by which reciprocating mot-ion is given to the cutting-plate D, whereby lost motion may be taken up to secure the proper action of the cutters, substantially as specified.
