- ineens THOMAS JOHNSTON, OF ALBANY, NEW YORK.
ROTARY Pnannn Hman.
Application led November 27, 1922. Serial No. 663,523.
T all whom t mog/ concern Be it known that l, THOMAS JOHNSTON, a resident of Albany,in the county ofy Albany and State of New York, a citizen of the United States, have invented certain new and useful Improvements in Rotary Planer Heads, of which the following is a specifica` tion. i n Y My invention relates to improvements in l0 rotary planer heads, vand one object of my invention is the provision of head which will permit easy and ready adjustment of the knives or cutters and which will insure be composed of few and simple parts, to
insure strength and durability, cheapness of production and general eiliciency and useful.-
ness.
lith these objects in view, my invention consists of a rotary planer head embodying novel features of construction and combina,- tion of parts for service, substantially as described andideined by the claims, and as shown in the accompanying drawings, in which Figure 1 represents a view of the comple .o cutter head taken on the line of 2, being for the purpose of clearness, partly in elevation and partly in section.
Fig. 2 represents a rview in elevation of the complete planer head, shaft and driving pulley to show the entire structure generally. n
Figure 3 represents a verticalv sectional yview of a modified form of my invention.
Figures 4r and 5 represent perspective views of the clamping members of my invention.
In the drawings, the numeral 1, designates the driving shaft, 2 the driving pulley on said shaft, and 3 the cutter head as a whole mounted to revolve with said shaft.
This cutter head may be made of any cutter or knife capacity desired and in this inthe cutter in the proper adjustment.
stance the head is constructed' with sin cutter or knife receiving channels et, which are of curved formation having one wall 5, provided with a recess 6 and its opposite Wall 60 7, formed with curved channel 8.
Fitting in the knife receiving channels are the curved split rings y9, one end 10 of which bears against the stopkor recess 6. and whose other portion 11, tits in the knife receiving B5 channel and is formed on its outer edge with a rack 12, Varranged to receive the tooth 13, on the inner end of the knife or cutter 15, which is thus disposed in the channel 8, of the head and is adjustable to bring its cutting edge 16, in proper place according to the character of work.
vFrom this construction it will be noted that the curved clamping rings are mounted in the channels of the head and that the cutters are adjustable in the channels and lwith reference to said rings, and for the purpose of clamping the rings andsaid cutters in proper place and holding them to their work, the said rings are formed with kerfs 17, in which lits the rib 18, of the plate 19, against ywhich bears the lower end 20, of the adjusting and clamping screw 21, which is disposer in the clamping block or member 22, which acts tobind and retain 85' The said member 22V is fori'ned with a rib 22X, which .tits in a groove 5. of the curved split ring 9, and serves to anchor themeinber 22 l in the most advantageous position with ref- 9G erence to associated parts, and forms an im#r portant and novel feature of my invention.
It will be noted that the rolling forward of the knives or cutters to bring their bevellcd cutting edges into the plane of rotaj tion so that all of the knives may be sharpened. winch is normally set tangent to the lplane of rotation. in one operation by sin ple revolution ofthe planer head, and which, after the knives are sharpened, may be rotated back into their original position, the knife edges thus automaticallytaking their proper position for cutting and thus doing away with the necessity for individual sharpening of the knives, which latter results often in the dulling of most of the knife edgesbefore they are actually 'used for planing purposes. i
From the foregoing description taken in connection with the drawings, the operation n0 and advantages of my invention will be readily understood andit will at once be apparent that the knives or cutters can instantly be ladj usted to the character of Work; that the knives or cutters may be used until they have been entirely Worn out insuring a long service and a great saving in expense; that the adjustment assures the cutters being held to their Work and removes the possibility of their Working-loose; and that 20 supports for saifdadjusting devices, said afdjusting devices consisting oit serevfs p ssi-ng through said clamping members having a head on their outer end and plates anchored 4in lsaid rings to support the inner ends of said screws.
2. ln combination with a rotary planer head having;` a series of channels, a series of Y Y split" rings'iitting in said channels, stops for engagement between the rings and Channels, racks formed on one Wall of said rings, ters having a tooth to engage said reeks to adjust said cutters, clamping blocks to seoure the rings and eutters in proper position, plates anchored in said rings and forming supports and adjusting screws mounted in said clamping members and having' their loiver end resting` on said supports.
In testimony whereof l hereunto aliix my signature.
THOMAS JOHNSTO.
