' 4 Claims. (01. 51+157) This invention relates to sharpening v devices for tools, blades and the like. More specifically it relates to sharpening devices wherein precision type of sharpening is made possible.
It is the general object of my invention to provide a novel and improved sharpening device for tools, blades and the like, said device being of' cheap and simple construction and capable of easy operation.
A more specific object is to provide an improved sharpening device through the use of which each of a plurality of tools, blades or the like may be repeatedly sharpened at the same angle each time even though each of said tools, blades or the like have sharpened edges of different angularity.
A further object is to provide an improved sharpening device capable of ready adjustment to permit sharpening of a given tool, blade or the like at a predetermined angle.
These and other objects and advantages of my invention will more fully appear from the following description made in connection with the accompanying drawings, wherein like reference characters refer to the same or similar parts throughout the several views, and in which:
Fig. 1 is a side elevational view of one embodiment of my invention secured for operation.
Fig. 2 is a top plan view of the same.
Fig. 3 is a front elevational view partly in section of the device with the tool which is to be sharpened positioned in a substantially horizontal position; v
Fig. 4 is a fragmentary side elevation view of the device, showing the clamping means used when sharpening. hair clipper blades;
Fig. 5 is a vertical sectional view taken along lines 5-5 of Fig. 4;
Fig. 6 is a bottom elevational view of the clamping means for hair clipper blades with a blade in proper position.
One embodiment of my invention includes, as shown in Figs. 1-6, a generally rectangularly shaped frame 8 which has a pair of spaced parallel tracks 9 and 10. This frame 8 is adapted to be secured by a clamp H to a table or similar structure indicated as [2. Fitted between the tracks 9 and I is an abrasive I3 which in turn is mounted within a box or holder M to hold the abrasive l3 immovable relative to the frame 8.
Mounted on the frame 8 within the tracks 9 and II] for reciprocating movement relative to the abrasive I3 is a carriage indicated generally as 15. This carriage I includes'an outwardly facing channel strap 16 which has secured to its opposite ends by pivot bolts ll a pair of spaced rollers 18. Secured to the medial section of the channel strap l6 by a wing bolt I9 is a metal strap 20. which is bent into a right angle so as i to provide a vertical portion adapted by a longitudinal slot 2| to be secured to the channel strap 16. The other leg of the strap 2il extends-inwardly and horizontally and is alsoprovided with a longitudinal slot 20a shown in broken lines in Fig. 2. The rollers [8 are carried by one of the tracks 9 and [0. Also secured to the channel strap l6 by the pivot bolts I! is a protractor 22 or similar angle measuring device which extends upwardly above the channel strap l6. This protractor 2g cooperates witha very narrow-slot 23 in the strap 20 to indicate the angle at. which the normallyhorizontal portion of the strap 29 is positioned with respect to a horizontal line.
. The remaining track carries a structure exactly the same as that described in the preceding paragraph; For thesake of brevity this other structure will be indicated as 24. V
Mounted above the two inwardly extending horizontal legs of the right angled strap 20 and its counterpart of structure 24 by means of a pair of bolts 25 which extend through the slots 20a of these legs is an inverted channel strap 26. This channel strap 26 provides the frame-work for securing thetwo side portions of the carriage IE to each other. Secured above this channel strap 26 is a plate 2! which has apertures provided therein to accommodate the bolts 25 as best shown in Fig. 2. Extending upwardly through the slots in the horizontal legs of the strap 20 and its counterpart and through the inverted channel strap 26 and through the plate 21 is apair of spacedwing bolts 28 which serve to cause the plate .21 to be rigidly secured to thechannel strap 26. Mounted on the wing bolts 28 between the channel strap 26 and the plate 2'! and extending forwardly relative thereto is a protractor or similar angle indicating member 29. Also car ried between the channel strap 26 and the plate 21 and above the angle indicator member 29 is a mounting arm 30. As shown this mounting arm 30 has a longitudinally extending slot 3! formed therein to accommodate 'a pointer element 32 which also hasa longitudinally extending slot therein to accommodate a wing bolt 33.- This wing bolt 33' extends downwardly through the plate 21, the pointer elements 32 and the channel strap 26 andis adapted to permit adjustment of the arm 30. to any predetermined angle'when loosened and to hold the arm 30 atsuch-an angle when tightened. v
The forward end of the mounting arm 30 is provided with a pair of spaced apertures 34 to accommodate a pair of bolts 35 with knurled heads 36. Mounted on the underside of the front end portion of the arm 30 by means of these bolts 35 at slots 300. provided therein, is a pair of plates 31 having registering depending portions 38. Each of. the, depending. portions 38 has an aligned apertureithrough. which a relatively long screw-'tightener 39 extends. When loosened this screw-tightener 39 will accommodate a pair of mounting clamps 40 each of which has a slot 4| formed in itsihorizontal:portion.
When tightened the screw-tightener'39'wiJlidraw these clamps 40 together to firmly hold a hair clipper blade 42 therebetween.
In operation the tool or bladefdesired-ito; be. sharpened may be mounted directly between the channel strap 23 and the plate 2! by removing the wing bolts 28 and 33 and substituting the same for the mounting arm 30 or-it maybe mounted on the arm 30-. The former-is true, of course, only when sharpeninga tool suchas=a hand plane blade ora 'similar tool 'wh-ich' has a longitudinally extending slot similar to the slot 3! in the mounting arm 30; If the tool or blade desired to be sharpened is of a difierent nature it may be secured 'to theend'of the mounting arm 39 by means of the mounting clamps ill with their screw-tightener39. -It is obvious of course, that clamps shaped otherwise than those shown as clampsMl may be used to grip securely any tool desired to besharpened. Once the tool desired to be sharpened has been secured to the carriage l in-the'manner just described; the'tool or the mountingarm carrying the tool should-beadjusted to'the desired angularity with respect to the abrasive'l3. The sharpened edge of the tool'may be brought into registration with the abrasive l3 by loosening the upper portion of the carriage 1-5 and tipping 32 is opposite the 45 degree mark on the angle measuring element 29. Once this has been accomplished the blade may be readily sharpened at the exact predetermined angle by similarly causing the carriage I5 to move backwardly and forwardly over the tracks 9 and It].
When it is necessary to sharpen a hair clipper blade or the, like the plate, 421s inserted between the clamping means- 40; and'ithe; screwtightener' 39 is tightened. "Thus the 'plate 42 .will be firmly secured at the end of the mounting arm 3|], but it will be free to rotate on the -axisof1the screw-tightener 39 to permit the blade to'be oriented in flat registering relation with the abrasive, a relation which is of great importance in sharpening clipper blades and the alike. The upperr iportion of the carriage I5 is it forwardly. If the tool or'blade'has been previously sharpened'at a predetermined-angle the upper portion of the carriage I5 should be tilted forwardly until the narrow slot 23--is directly above the predetermined angle 'asindicated on the anglemeasuring element 22, thereafter the wing bolt 33 should be loosened and the-tool or the mounting arm 30 shouldbe moved-longitudinally until the sharpened edge registers with the abrasive 13. This will insure thatthenew edge will -have the desired angularity and will therefore prevent waste of the-main body of the tool itself as a result "of sharpening. 'The above instructions apply" for setting a tool or blade the sharpened edge of'which extends at right angles to the length of the tool or blade. It can be readily seen'of course, that once the device has been properlyset'it is'an'easy matter to sharpen the tool or blade by causing the carriage 15 to reciprocate with respect to the tracks 9 and It).
When a tool or blade the sharpened edge of which extends at an angle to the length ofthe tool is desired to be sharpened, the tool is-mounted as described above. However, prior to commencing the sharpening operation, wing bolt 33 is loosened and the blade'tobe sharpened, or the mounting blade 30 holding the blade, may be swung to either side to the exact predetermined angle to which the blade was "previously sharpened. Thus if a tool has a sharpened edge which extends at an angle of-' degrees to the length of theblade, the mounting arm 30=should be swung to the side, until the pointer element able in size since the upper portions thereof may be inserted between the depending'-portionsl 38' of the mounting plates 3-1.
One of the principal advantages ofmy invention is that it provides a mounting structure or carriage which permits theuser tosharpenpractically any type of" blade or tool at anexact predetermined angle. This true whether the sharpened edge of the tool or blade'liesstraight across the tool or extends 'at an angle thereto. Since it is possible tosharpen such a blade at a predetermined angle 'my invention" saves time and effectively eliminates theiwaste and inaccuracy .normally involved in attempting to sharpen a toolat. a given angle by manually holding 1 the same. When using my invention the operator is assured-of acutting edge of the most desirable formv or angulation. It canflbe readily-seenthatit is-very important that a tool which-has once been sharpened. at. a given angle should, when sharpened the next .time, be sharpened at exactlythe. same angle. 'Itis possible to sharpen turn lathe chisels, straight chisels, clipperxbl'ades, jointed bladesand similar cutting tools with a minimum of time and inconvenience when using -my invention.
-It-will; of ccurseybe' understood that various changes may be madetin the form, details, arrangement and proportionsfof the: various parts without departing from the scope 'ofi myinvention.
