LUMBER MARKER .AND GRADER.

Specifcatonof Letters Patent.

Patented Feb. 1, 1921.

Application led July 29, 1916. Serial No. 112,142.

To all whom it may conce/fm- Be it known that I, Josnrrr Mc- DoNoUGH, a citizen of the United States, resident of Eau Claire, county of Eau Claire, State of Viscousin, have invented certain new and useful Improvements in Lumber Markers and Graders, of which the following is a specification.

The object of my present invention is to provide a machine primarily designed for marking or branding and grading timber of varying dimensions, the brand and grade being applied at intervals on a longitudinal surface to prevent a piece of lumber or timber from being retrimmed or cross cut and sold under another trade-mark and brand than those originally applied.

A further object is to provide an apparatus which will mark and grade the lumber or mark without grading, as may be desired.

A further object is to provide a machine by means of which several surfaces of the lumber or timber can be simultaneously marked or marked and graded.

Other objects of the invention will appear from the following detailed description.

The invention consists generally in various constructions and combinations, all as hereinafter described and particularly pointed out in the claims.

In the accompanying drawings forming part of this specification,

Figure 1 is a plan view of a lumber or timber marking and grading machine embodying my invention,

2 is a front elevation of the same,

Fig. 3 is a side elevation, partially in section, illustrating the manner of supporting the marking and grading device and showing its manner of contacting with the surface of the lumber,

Fig. 4 is a detail sectional view, showing supporting means for the disks,

5 is a sectional view taken on line .0f-a2 of Fig. 4, looking in the direction of the arrow,

Fig. 6 is a top view of the lower disk,

Fig. 7 is a bottom view of the upper disk,

Fig. 8 is a section taken on line g/-g/ of F ig. 4, looking in the direction of the arrow,

Fig. 9 is a side view of the complete marking and grading disk, showing some of the characters thereon,

Fig. 1Q is a detailjview of additional gradingv blocks mounted in the' upper disk,

Fig. 11 is a detail sectional view, showing yielding means for said disks.

In the drawing, 2 represents a frame having driven rolls 3 and near one end-of said frame I provide a swing cut-off saw 4. This is all of ordinary construction as used in planing or saw mills. Within reach of the saw operator I mount the marker. The frame 5 of the marker has bearings 6 for a drive shaft 7, having clutch connections at 8 with a sprocket 9 driven by a chain 10 from the sprocket on one of the driven rolls 3. A bevel gear 11 on the shaft 7 meshing with a gear 12 drives an uprirht shaft 13, also mounted on the frame 5. frame 14 is pivoted on said shaft and at its further end is provided with a bearing 15 for a hollow shaft 16, said shaft being driven by means of a sprocket 17, chain 18 and a sprocket 19 on the shaft 13. The short hollow shaft 16 has at its opposite end a marking disk 20 having the same peripheral speed as the rolls 3.

The disk 20 is provided with a peripheral die 21 corresponding to the trade-mark or character that it is desired to impress or brand on the surface of the lumber or timber, and this die is positioned to make one impression on the lumber with each revolution of the disk and as the disk is approximately three feet in circumference, an impression of the mark will appear every three feet on the face of the lumber with which the die contacts. i

@n the opposite side of the machine I provide a similar marking disk and supports therefor, which I will designate by the same reference numeral, with the addition of the exponent a In the plan view. Fig. 1, I have shown the disks 20 and 20a bearing on the opposite faces of a piece of timber fed between them, and for holding the disks snugly against the timber I prefer to employ the following described mechanism:

23 is a yoke, supported on a threaded shaft or screw 24. 25 is a cross head, loosely mounted on said shaft and adjustable toward one end of the yoke by means of a set screw 26 mounted in a lug on said yoke and bearing against a similar lug on the cross head. A compression spring 27 is interposed between the cross head and an oppositely arranged end of said yoke. The cross head is pivoted at 29 to the swinginglframe 14 and a similar mechanism is provided for connection with the frame 14CL on the opposite side of the machine.

To adjust the yokes toward or from one another to allow for different Widths of timbers to be marked, I provide the. crea7 or shaft 24 with universal `ioints 30 and 3l, connected with a short shaft and a square shaft 33 having bearings in a sleeve 34 mounted in suitable bearings and provided with a sprocket 35 driven by a chain 36 from a sprocket 3? on a shaft 38. A large cone 39 on said shaft is driven in opposite directions by n cans of small cones 4G and 4l mounted on the shaft 42 and driven by a pulley 43. Shifting clutch connections 44 on the shaft 42 permit either the cone 40 or 4l to drive the large conel) and allow the turning of the screw in either direction for bring-ine; 'the disks closer or farther apart, and the sliding shaft 33 With the universal oints Will allow for any alincment of the frames 14. For instance, the left side frame be parallel to the timber, While the opposite frame Will be at an amrle. The springs 27 on the screw shaft 24 will bc put under tension when timber is between the disks. lnkinpj rolls 45 distribute ink to the character 2l when contacting' with same.

Thus the means for marking' a trade-mark is described. l will now proceed to dcscribe the means for marking; the trade of the timbers and printing same thereon in connection With the former mark.

Within the hollow shai't l@ is a shaft 45 f upon which mounted a secondary disk 4T.

ln openings 48 of the disk l provide bloc ci; 49 havingr different grade marks. The block is preferably in 'the form of a letter "i" and has a face 50 upon which is stamped Grade mark. Between openings 4S are lugs 5l and the blocks 49 rest between said lugs and lugs 52 on the d' ik. Each block 4f) has a slot 52. compression spring' bears against the end of the block and a lug; on the upper disk 4T and its tendency is hold the mark characters out of engagement with the timber. (flee 5). 'Y

rlhc blocks have a tooth to ene: inclined edge 5? of the lug); 5cl on the u ilfhenever it is desired to use idk 20. another mark the operator revolves the disk 4. T he tooth on the next block 45) ener-.ees the block 58 and moves outward and drops back sufficiently to have the tooth 5G engage a tooth 59 on the block 5S and 'thereby the disk 417 The mark in engagement ivith timberas it is beingl 47 may be advanced idle by means of a hanbv power through the will be driven with the disk 20, on said block will come the inkingi` rolls'nnd the driven. Said disk when the disk 20 is dle 60, by hand or Vsprocket (Si on the shaft 46, chain G2 and sprocket G3 on a hub of a 4gear G4 loosely mounted on the shaft 13. Said gear is in engagement With a gear 65 on the shaft Gf ieaoee A sprocket 67 has chain connections 68 with a sprocket 69 on a sha1'U 70. A friction disk 7l on said shaft is driven by a pinion Z 2 on the shaft 73, provi(l ed with a driven pulley T4. A suitable clutch '75 be connected with said pinion on the shaft 73.

l prefer to provide one of the blocks 49 Without characters, so when it is desired to print the trade-mark alone, said block will hold the lower and the upper disks in engagement so that they Will revolve together.

Above said blocks l prefer to provide one or more blocks that are not so extensively used. The blocks 75 are free to slide in a groove in the disk 47 and are held either in or out of engagement with timbers means of spring pressed pins '77 to engage either of the holes 78 or 79.

'l` he operation of the machine is as follows:

The operator sets the disks 2O and 20qu a proper dif'itance apart and as the timber comes in contact therewith the proper of characters Will be printed on each side of the timber and full length thereof a distance apart corresponding to the circumference of the disks.

This device may be made in various sizes and in various Ways the details of construction herein shown and described may be modified and still be Within the scope of my invention.
