2 Claims.
The present invention relates to a readily adaptable precision type portable clamp-equipped device for accommodating and holding plane 4 irons and chisel blades in order to eifectively subject the cutting edges to the treatment of a conventional oilstone, whereby to insure the production of a keen and perfectly finished cutting edge.
Briefly, the preferred embodiment of the invention is characterized by a roller equipped carriage unit, this unit having perpendicular cylinders and said cylinders being provided with internal cushioning springsto accommodate balancing and yieldable pressure producing plungers, the latter constituting supports for the swingably mounted blade -holding clamp.
In carrying out the principles of the invention I have evolved and produced a relatively simple and expedient mechanical appliance, characterized by a gauge-equipped clamp unit pivotally mounted on an easily and readily shiftable spring balanced carriage unit.
Other features and advantages will become more readily apparent from the following description and the accompanying illustrative drawings.
In the drawings:
Figure 1 is a side elevational view, with a portion of one of the parts broken away and shown in section, said view illustrating an oilstoning device constructed in accordance with the principles of the instant invention.
Figure 2 is a top plan view of the complete assemblage depicted in Figure 1 showing the manner in which the device is used in conjunction with the conventional oilstone.
Figure 3 is a central longitudinal or vertical sectional view taken approximately on the plane of the line 3-3 of Figure 2.
Figure 4 is an end elevation of the devices appearing in Figures 1 and 2, observing the same in a direction from right to left.
The overall device is characterized essentially,
by a carriage unit A, gauge-equipped adapter members B supported thereon, and a clamping unit or means C for the blade to be sharpened.
The carriage A comprises a pair of perpendicular cylinders 5 arranged in opposed parallelism, the cylinders being mounted on the frame members 6, the latter terminating in legs carrying the surface contacting rollers 1. Appropriate horizontal braces 8 and 9 are arranged betweenthe frame members to provide a substantially sturdy construction. Each complement B comprises a cylindrical plunger 10, this mounted for reciprocation in the cylinder provided therefor. There is a coiled cushioning spring II in the lower end of the cylinder and the adjacent end of the plunger rod rests thereon as shown to advantage in Figure 1. The plunger in effect is a reciprocatory spring-cushioned post and each post is provided with a lateral extension [2 which may be of segmental or sector configuration. The part I2 is provided with an arcuate guide slot l3 and suitable coacting graduations l4 providing an appropriate indicator or scale.
The clamp unit C is made up of a heavy main supporting plate l5 and a companion smaller binding plate l6. Thelongitudinal edge portions of the plate I5 are pivotally mounted as at the point I! between the upper end portions of the spring-cushioned plungers Ill. The work, which is in this instance a plane iron I 8 is clamped between the companionplates [5 and Hi. The
plates are bolted together as at the points l9 whereby to permit the iron l8 to be shifted up and down between the two plates to obtain and maintain the desired adjustment, that is, in re-- lation to the oilstone l9. Further, and as is brought out in Figure 2, the main base plate l5 of the clamping unit is provided with outstanding screw-threaded studs 20 which extend through the gauge slots l3 and are provided with nuts 2! for adjustment and clamping purposes. The entire clamping means is pivotallymounted on the posts or plungers' l0 and after the primary adjustment of the work is made in relation to the plates l5 and IS, the secondary adjustment of angularity is accomplished by Way of the studs 20, clamping nuts 2| and gauge slots I3. Then, the unit C becomes a temporary integral part with the two units B and all three parts are' bodily adjustable in relation to the steering and balancing carriage. The carriage is shifted back and forth in relation to the oilstone and the super-structure comprising the clamping means and posts is perpendicular adjusted by hand pressure to obtain the desired blade beveling and sharpening results.
The device, as before stated, is used for oilstoning plane irons or chisels and has the advantage of producing an accurate and true bevel and, therefore, a keen cutting edge; which otherwise would not be possible, even if extreme care were taken to prevent the rounding of the bevel, when the job is done, as ordinarily, by hand.
It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after considering the description in connection with the l drawings. Therefore, a more lengthy description is regarded as unnecessary.
Minor changes in the shape, size and arrangement of details coming within the field of invention claimed may be resorted to in actual practice, if desired.
Having described the invention, what is claimed as new is:
t 1. In a structure of the class described, a carriage comprising a pair of vertica1 cylinders, coiled springs located in the lower portions of said cylinders, frame members attached to said cylinders, rollers mounted on said frame members,
plunger rods slidable in the cylinders and coacting with the springs in said cylinders, said plungers' being provided at their upper ends with sector-shaped slotted members, a pair of clamping plates, one of said plates being pivotally mounted on the upper ends of said plunger rods,
, said plates being provided with outstanding studs, said studs being screw-threaded and projecting through and beyond the slots in said slotted members, and clamping nuts on the screwthreaded ends of said studs.
2. In a structure of the class described, a carriage comprising a pair of vertical cylinders, coil springs located in the lower portions of said cylinders, frame members attached to saidcylinders, rollers mounted on said frame members, plunger rods slidable in the cylinders and coacting with the springs in said cylinders, said plungers being provided at their upper ends with sector-shaped slotted members, a pair of clamping plates, one of said plates being pivotally mounted on the upper ends of said plunger rods,
said plates being provided with outstanding
