. Specification of Letters Patent.

Patented Apr. 24), 1915.

Application filed June20,1914. Serial No. 848,353.

To all whom it may concern Be it known that 1, Jesse Fosnenmne,

. a citizen oflthe United States, residing at Missoula, in the county of Missoula and State of Montana, khave invented.certainnewand useful Improvements in Woodworking- Machines, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements'in wood working machines, and more particularly to jointers, the primary object .of the invention residing in the provision :of improved means for :mounting and adjusting the abrasive lblOGk or blocks with respect to the jointer head of the machine, whereby the same may 'beadvantageously employed in connection with jointers for fiooring,-silo materials, wooden culverts, .and the like.

Ilhe invention'has produce a jointer which is so constructed that the various adjustments mayibe easily quickly, and accurately made, andthe parts will retain their adjusted or set positions and not be displaced by :the vibration of the machine. 7

The invention has for still another object I to produce a jointer for wood working machines Wll-lCll is 811111 318 and durable 1n its construction, highly reliable and efficient in practical use and capable of manufacture at comparatively small cost.

With the above and other objects in view, the invention consists in novel features of construction, combination, and arrangement of parts as will be hereinafter referred to and more particularly pointed out in the specification and claims.

For a full understanding of the invention, reference is to be had to the following description .and accompanying drawings, in which.

Figure l is my invention applied .to use;

a side elevation illustrating in its preferred embodiment Fig. 2 is a top plan view;

Fig-3 is anend elevation; Fig. i is a section taken on the line of ig. 3; and Fig. 5 is a section taken on the line 5.5 of Fig. 2,.and Fig. 6 is a section taken-on the line 66 of Fig. 2.

Referring in detail to the drawings, 5 designates what is commonly known in the art as thechip breaker plate of a wood working machine, and-6 indicates {the jointer -:head. In the platevor base 5, a dove tail for a further .obj ect to v groove or channel 7 is formed, though it is to be understood that my invention is not to be hmited to any particular manner of mounting the device itself inposition with respect to the jointer head.

The slide base 9 of my improved jointer 1s movably mounted in the groove or channel 7, and is adapted ztO .be rigidly held against-longitudinal shifting movement in said channel by a clampingibolt 10 which is dlSPOSBd through an opening in the plate 5, and has threaded engagement in the base 9. Upon the basev plate 9 a bar 11 is mounted for longitudinal sliding movement, said bar 11 being provided with oppositely beveled or inclined flanges 12 for engagement with the under-cut abeveled side walls 18 of the groove or channel provided in the upper surface of the base 9, upon which the bar 11 is mounted. Upon oneend of the bar 11 an upstanding, lug 1 1 is formed, and this lug is provided with a threaded opening to receive athreaded adjusting rod 15 which is rotatably mounted in a bearing standard 16 fixed upon one end of the base 9. A suitable crank 11 1s secured to one end of the rod '15 whereby the same may be turned. llhe other end of the bar 11 is increased in-width and formed with spaced cars 18. The corresponding end of ;the base plate 9 is cut away to permit of the free turning or pivotal movement of the lower end of an adjustable block carrying frame indicated generally by the numeral 19. This frame consists of the parallel side bars 20 which are rigidly secured at oneof their ends upon the opposite sides of the spacing block 21. A bolt 22 connects the cars 18 and upon said bolt and between the ears, the ends of the bars and the spacing block are loosely mounted. The other ends of the side bars 20 of this frame are connected by the metal plate 28. Each of the bars 20 is provided upon its inner face and adjacent one of its longitudinal edges with a guide channel or groove 241- having a beveled .or inclined wall for engagement with. the correspondingly inclined flanges 25 of the slide block 26 which is mounted for longitudinal adjustment upon the pivoted frame 19. This block is provided at its upper end with an extension or lug 27 having a threadedopening to receive an ad ust- 29 designatesa suitable crank handle with which the upper end of the adjusting rod is equipped, whereby'the same may be readily turned and the slide block thusshifted upon the frame. This slide block is preferably formed with provision for two blocks 30 of 1' suitable abrasive material. These blocks are securely clamped in position in the'slideby the longitudinally extending plate 31 which is arranged upon one side of the block reportion of this arm is obliquely inclined and terminates in a threaded boltor shank 37 1 which is disposed between the spaced bars of the quadrant 33. A washer38isengaged upon the bolt or shank 37 and provided with lugs 39 extending upon the outer sides of the spaced quadrant bars. A'nut 40 is threaded upon the shank 37whereby the quadrant may be securely clamped against movement with respect to the inclined'arm 36 between the washer plate 38 and the shoulders 36 on said arm. The upper surface of one of the spaced bars of the quadrant is accurately graduated in degrees, as

shown at 41, and upon the arm 36 an index member 42 is secured, said'member projecting upwardly between the spaced bars-of the quadrant as shown.=

In the use of the devicefthe adjusting screw 15 is turned to slide the bar and dispose the abrasive blocks 30 in contiguous relation to the knives on the jointer head 6. These blocks'are then properly adjusted by rotating. the threaded rod 28 so that the knives will engage with the blocks in the rotation of the jointer head. The frame 19 in-which said blocks are carried isthen disposedat the proper pitch or angle by adjustingthe quadrant 33 upon the upper end of the inclined arm 36 in the manner above stated. By providing these'several adjustments, the device may be employed for j ointing wide knives which are set straight upon. 7 the jointer head, or beveled edge knives set at an angle upon the head. The devicemay also be effectually used in jointing heads to be employed upon a flooring having either a square or angle joint, or silo material which is usually cut in circular form. Theseveral adjustments maybe very easily and "quickly effected and the greatly facilitated.

"vention, it will be obvious susceptible of considerable otally connected at one of itsends to said for adjusting movement with/respect to the bars 'JOlIItIIIg operation J 7 Owing to the extreme simplicity of my inthat the device can be produced at very small manufactun' ing cost, and the same is also durable as well as highly serviceable and convenient in prac'-- tical use. V j

vlNhile I have above described the pre fer-red form, construction, and arrangement. of the several elements employed, it will be understood that the device is, nevertheless,

modification therein, and I therefore reserve the privilege of resorting to all such legitimate changes as may be fairly embodied withinthe spirit and scope'of the inventionas claimed. 1 g

- What is claimed is: i

1. In .a jointer for wood working machines, a base, aslide member longitudinally adjustable upon said base, a frame pivotally mounted upon said member, abrasive means 5 longitudinally movable in said frame, means for adjusting. said :abrasive imeans in the frame, and means for securing said frame uponthe slide member in various adjusted positions. a r f 2.111 a jointer for wood working machines, a base,a slide member longitudinally adjustable upon :the base,
