CUTTER-"SETTING GAGE.

SPECIFICATION forming part of Letters Patent No. 660,005, dated October 16, 1900.

Application filed February 8, 1900. Serial No. 4,480- (No model.)

To (on whom, it may concern.-

Be it known that we, WALTER E. DAVIS and J AMES LESLIE SAMSON, residing at Elizabeth, in the county of Union and State of New Jersey, have invented a new and useful Outter-Setting Gage, of which the following is a specification.

This invention is in the nature of an improved gage or device designed for use on molding machines, (woodworking) and it primarily has for its object to provide a simple, effective, and easily-manipulated means whereby the operator can accurately set all of the cutters or knives upon the cylinder to bring the cutting edges thereof an equal or uniform distance from the cylinder and also render the adjustments of the several knives such that they will effect a like cutting action and avoid the danger of having but one knife or cutter doing all the work.

This invention also comprehends in a gage or device for the purpose stated a certain construction of parts whereby the cutters can be adjusted laterally for different work in less than one-half the time it now usually takes to set them.

This invention also has for its purpose to provide a simple construction of gage capable of being reversibly used, whereby it can be conveniently applied to the different heads of the machine.

In its subordinate features this invention consists in certain details of construction and peculiar combination of parts, all of which will be first described, and then pointed out in the appended claims, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation of the cutterhead with our improvement applied. Fig. 2 is a cross-section of the same on the line 2 2 of Fig. 1. Fig. 3 is a perspective View of the gage. Fig. 4 is a face view of the side opposite that shown in Fig. 3. Fig. 5 is a cross-section of a modified form hereinafter referred to, and Fig. 6 is a diagrammatic View hereinafter specifically referred to.

Referring now to the accompanying drawings, in which like characters indicate like parts in all the figures, 1 indicates the cutterhead, and 2 the planers or cutters,which have the usual bifurcated ends 2, whereby they can be adjusted longitudinally on the headclamps 3, which clamps are adjustably moun ted in the T-slots 1 of the head 1, which provides for a lateral adjustment of the cutters, such arrangement of parts being that of the common form of cutter-heads, and they therefore, per 86, form no part of this invention.

Our improved gage comprises a body portion 4, made of a single piece and having an elongated shape. One or both of the outer portions 4 of the body 4 form ruler edges, whereby the gage may be fitted squarely against the cutter-head, as shown in Fig. 1. The opposite faces of the body 4 are rabbeted or recessed their full length, as indicated by 5, the opposite edges 5 of the recesses forming guides for the slides 6 6, said edges 5 running parallel with the ruler or squaring edge 4. The body 4 is also provided with an elongated slot 7, that runs parallel with the edges 4 5, the purpose of which will presently appear.

6 6 indicate two slides, each of which consists of a pair of fiat pieces 6 6, having a thickness equal that of the recesses in the faces of the body 4, whereby their outer surfaces will lie flush with the outer faces of the said ruler-body 4, as clearly shown in Fig. 2. In the preferred form the two pieces 6, that constitute the slides, are joined by an intervening block 8, that fits and slides within the slot 7, such construction providing for securing the parts of the slide and making the same as one member, which also, by reason of the slot 7 facilitates the moving of the slides on the ruler-body by finger-pressure, as-the end of the finger can partly enter the slot 7. e desire it understood, however, that the slot 7 may be omitted, and instead of joining the two slide members 6 said members may be independently held, one in each side of the body 4, and slid into the recesses of the said body, and when thus formed they can be readily held in place by dovetailing the edges 5 and the cooperating edges of the slides 6, as indicated in Fig. 5. The upper or gage edge of the body 4 has a projection 9 at one end, formed with an abutment-face 9 proj ecting up at right angles from the said squaring edge, the purpose of which is to provide for conveniently and accurately holding the gage on the cutter-head surfaces, and especially to bring the scale 10, (having the usual inch measure,) that is used'for adjusting the set of the cutters laterally, in proper position,

as will presently more fully appear. The

scale 10 is disposed on one face of the body 4 adjacent its squaring edge and stepped 0&-

to rear from the projection 9 toward the right, a similar scale 10 being provided on the opposite face of the body 4, which is stepped off to read from the left or outer edge toward the projection, as shown, the. advantageflof which will presently appear. The outer surface of the slide 6 has graduations 12, disposed in a horizontal plane-i. 2., parallelwith the squaring edge of the gageand the said graduations 12 are on the contiguous edges of the slides, whereby the two sets vof depth of the cut say one-sixth of an inch,

the cutter must be moved in the direction of the line A D about .077 of an inch, (more or less, as the size of the head and cutters may make necessary,) it being understood that by reason of the tangential adjustment of the cutter the distance that the cutter can be moved to effect the depth of cut desired increases proportionately with each movement of the cutter toward the line A D, or the last graduation on the slide, at which point the distance the cutter must be moved to efiect,

say, one-sixteenth of an inch of depth of cut.

is about .068 of an inch.

By providing movable slides, as shown, an.- other and advantageous result is obtained in that the edges X of the slides form a movable continuation of the scale-marks that run at right angles to the gradautions 12 upon the slides. As the cutters usually project beyond the rulescale on the upper edge of the body 1, the said edges X serve to give a long scalemark or line by which to properly set the edges of the cutters when they are moved laterally. Again, when it is necessary to set the cutters alike on both the right and left. heads the reverse side of the cut gives the correct adjustment of the opposite cutters without further alteration.

By providing the body of the gage with slideways in which the slides can be detachchangeably used and the different slides graduated to suit the different-sized cutter-heads.

It will be also manifest that the length and width of the body of the gage may be changed to suit the requirements desired. From the foregoing, taken in connection with the accom panying drawings,it is thought the'advantages of our improvement will be readily apparent to those skilled in the art to which it appertains.

' By providing the ruled scales 10 10 the slide 6 can be quickly slid laterally to the point desired and the cutters moved correspondin'glysidewise to their proper adjustment, the latter operation with the use of our gage being effected in a much less time than it now requires to set the cutters sidewise in the usual way.

Our, improved gage can be made entirely of wood orpart wood a'ndpa'rt metal, and its construction is such as to admit of its being made without the necessity of providing some special arrangement of mechanism to produce it. ,I V
