UNITED STATES PATENT OFFICE..
JOHN VERMEULEN, OF NEW YORK, N.' Y.
KNIFE-POLISHER.
SPECIFICATION forming part of Letters Patent No. 434,365, dated August 12, 1890. Application filed January 14, 1890. Serial No. 336,878. (No model.)
` in which similar letters of reference indicate corresponding parts in all the figures.
Figure l isa side elevation of the improvement. Fig.2 is a plan view of the saine. Fig.
3 is a transverse section of the same on the line 0c of` Fig. l. Fig. 4 is a similar view of the same on the line y y of Fig. l. Fig. 5 is a face view of a sharpening-roller of modified form. Fig. 6 is a side elevation of the same, and Fig. 7 is a plan view of the spring-plate for holding the stationary strap in place.
The improved knife-polisher` is provided with a suitably-constructed bed-plate A, from one end of which, at the under side, extends an Lshaped arm B, in which screws a screw C, for securely fastening the bed-plate A to a table or bench. On the front end of the bedplate A is mounted a lknife-polishing device D, provided with a fixed polishing-strap E and a yieldingly-mounted strap F, of which the latter is located above the former, and between which the knife to be polished is placed,
as hereinafter more fully described.
The straps E and F are preferably made of leather.; but other suitable material may be employed. The strap E is stretched trans- Versely over part of the bed-plate A, and has its ends extending downward and over the downwardly and inwardly inclined lugs or iianges A', formed on the under side of the bed-plate A. The ends of the strapE are securely held in place by a spring-plate G pressing the ends of the strap against the inclined lugs A', as is plainly shown in Fig. 3. Vhen the strap E is worn out, it can be easily and conveniently replaced by prying the springplate G from under the bed-plate A, then rcmoving the worn-out strap, replacing it by a new one, and then again inserting the springl plate G, as above described. The other strap F is passed under a plate H, provided at its sides with upwardly and inwardly bent lugs or .p 5` 5 fiangesH, overwhich pass the ends of the strap F, which are held in place at the inside of the said lugs or flanges by a spring-plate I, similar 1 to the spring-plate G, previously mentioned. At the inner end of the plate H are formed up- 6o wardly-eXtending lugs J, each provided witha vertical slot J', through which pass the ends of a pin K, held in the lugs A2 erected on the bed-plate A, as is shown in Fig. 2. The vertical slots J in the lugs J permit the plate H to rise parallell with the bed-plate A, and also to swing upward whena wedge-shaped knife is inserted between the two straps E and F, the pin K thus being the fulcrum.
On the pin K, between the lugs A2, is coiled 7o a spring L, having its middle part extended upward to engage a screw N, screwing in a lug O, formed on an offset O, held on the rear of the bed-plate Aand forming part of the knifesharpening device. The ends of the spring L extend at about right angles to the upwardly -bent or middle part of the said spring and press on thetop of the plate H, so as to hold the strap F of the latter against the strap E or against the knifewhen inserted.
In the middle of the plate H is formed a hopper P, which opens through an aperture F in the strap F upon the stationary strap E. This hopper is adapted to receive the polishing material, which can pass from the hopper through the opening F between the two straps E and F, or upon the knife when inserted between the two straps. l
The offset O, previously mentioned, and forming part of the knife-sharpening device, 9o is provided with a vertically-extending slot O2, into the lower part of which pass the rims of the two sharpening-rollers R and R', secured on shafts Q and Q', mounted in the offset O,parallel with the sides ofthe slot O2. Each of the rollers R and R has V-shaped annular ridges R2 on its periphery. The outer sharp edges of the V-shaped ridges nearly y touch the center of the slot O2, as is plainly shown in Fig. 1, so that when a knife is inroo serted inthe slot O2 and pressed down on the rollers, and drawn inward or outward, its
held between the two wheels and adapted to engage oppositely-arranged teeth, so as to prevent the said wheels from turning to hold the rollers R and R in place. The plate T is secured at one' end on a transversely-exA tending shaft U, arranged to slide in suitable bearings in the offset O, and provided at its.
outer end with a head U, on which presses one end of a spring V, held in a suitable recess O3 of the offset O. The spring Vhas the tendency topress the head U outward, thus holding the plate Tin contact with the front face of the offset O, at the same `time engaging the said plate with the toothed wheels S and S. Then the rollers R and R have become worn by use at the point which extends into the slot O2, then the operator presses on the head U of the shaft U, so as to shift the shaft U inward, thereby disengaging the plate T from the notched wheels S and S. The operator can then turn the notched wheels the distance of one or more teeth, so that new points of the ridges R2 of the rollers R and R come in the slot O2.
The device is used as follows: The bedplate A is secured in a suitable manner to a table, bench, or bracket, and when the operator now desires to polish a knife he first fills the hopper P with a polishing material and then inserts the knife between the straps E and F in such a manner that the knife-edge extends toward the pin K. The spring L then presses the strap F firmly in contact with the top of the knife, while the bottom of theknife rests on the lower stationary strap E. As the knife is usually wedge-shaped in cross-section, the upper strap F assumes an inclined position, turning on the pin K, as previously described. The tension with which the spring L presses on the plate H can be regulatedv by adjusting the screw N, so that the spring L presses with more or less force on the knife to be polished. The operator then moves the knife-blade transversely between the two straps E and F, so that it is polished by the said straps and the polishing material passing to the said straps vand the knife, as is previously described. When the knife has been `polished or cleaned and the operator desires to sharpen it, he places the knife-blade in a vertical position with the knife-.edge down.
ward and inserts it in theslot Q2 until the knife-edge rests on the V-shaped ridges R2` The operator then draws the knife-blade transversely several times, pressing down on it so as to hold the. knife-ed ge firmly in contact with the V-shaped of the rollers R and R.
ridges of the rollers R and R while drawing the knife forward and backward. The knife is thus sharpened.
The sharpening-rollers R and R may each be made of solid steel or of a series of washers placed on the respect-ive shaft Q or Q', as shown in Figs. 5 and G. In order to hold the washers on the shaft, the latter is provided with a attened side, and a corresponding aperture is formed in each washer.
It will be seen that the device is very simple in construction, can be cheaply manufactured, and will form an indispensable household article.
The knifesharpening devices are not claimed herein, but will form the subject of a separate application.
Having thus fully described my invention, l claimas new and desire to secure by Letters Patentl. A knife-polisher consisting in the stationary plate A, having depending parallel ribs or ianges A A along its side edges, a strap E, passed over the plate and around the said ribs or flanges, a spring clamping-plate extending from rib to rib and clamping the ends of the strip against said ribs, and an upper spring-pressed plate having parallel upwardly-projecting ribs or flanges H along its side edges, a strap F, passed along the lower face of said plate and having its ends folded over said ribs or flanges, and a clamping-plate extending from one rib Il to the other. and clamping said overturned ends thereto, substantially as set forth.
