Application and August 15, 1922. Serial n. 582,731 i To all whom it may concern: Be it known that I, HENRY H. PAYZANT, a citizen of the United States, and resident of Everett, county of Snohomish, State of I Washington, have invented certain new I and useful Improvements in Lumber- Marking Devices, of which the following is a description. a The object of this invention is to provide sim le, efiicient and durable means for mar ing lumber and similar articles." The nature of the invention will clearly and sufticiently appear from the following descrip tion, the drawings and the claims.

1 Figs. 1, 2 and 3 are side elevations of a machine. which is an embodiment of the invention, showing the machine in prqgr'es:

'sive stages of operation. Fig. 4' is a. cross section of Fig.1 on the line Y-Yviewed from the readers ri ht. ,Fig. 5 is a cross section-of the same ig. 1 .on' the line X-X but viewed from the opposite direc tion.

In ,my application, Serial No. 502,176,

filed September 20, 1921, I. have discloseda means for marking lumber, wherein the lumber may be marked either at the end or on the side, orboth-the end and on the side in one operation.

' The present invention is concerned with an endmarkin device, and employs an oscillating. weig ted die-carryingmember and an oscillating ink-carrier, both being actuated by the movement of the advancing material to be marked. which. in this in; stance, is a piece of lumber. The ink carrier is normally in contact with'the dic carrier, and is first moved out of the way by the movement of the lumber. the die 7 carrier bein then brought into forcible con-- tact with tie end of'the lumber with sut ficient resistance due to the provision of 5 the weighted means, as to make 'an impression on the end of the piece of lumber.

. One of the improvements resides in a toggle connection between the weighted means and the die-carrying member, in-

steadmf a direct connecting link, as in the aforesaid application. a 1;] Another'improvement is in the employment of a pivotally mounted ink carrier which is actuated by the moving lumber,

rather than by the die-carrying member, as in the aforesaid application. Another improvement is the means for adjusting the marking device for different thicknesses of lumber.

Still another improvement is in the connection between the die-carrying member and the inking member, whereby the relation between the face or inking portion of the inking member and the face of the die- 1 carrying member, remains the same, irrespective of either point of contact. The supporting casting -1-is suitably attached by bolts 2 3, to a convenient supportsuch as the illustrated wooden framework. -.Plate 4 is mounted on the castin 1 by bolt 2' and is adjustable verticafily through pin 5, rod 6 and hand nut.'7, being clamped firmly during operation to casting 1 by adjustable stud 8. The plate carries weight arm 9'by bo 10, weight ,11 beingsecured by in 12 to the weight arm. The other end 0? the weight arm moves freely in parallel guides 13' (only one being shown), connected by pins 14, 14. Upon the weight arm is pivotally mounted toggle arm 15 tozwhich is pivotally connected toggle arm 16. i" 1 --1 Parallel links 17, 17 swing on spindle 18, which is attached-to plate 4;. Pin19 conmeets their opposite ends and also pivotally supports the die carrier 20.' The die 21 is suitably inserted in the die carrier or may be an integral part thereof. w

1 The die carrier 20 is connected by its pin 22 and spring 23 on. toggle arm 16 to said toggle arm the spring being provided so that the toggle arms 15, 16 will not be centered. Ink carrier 24 is hin ed on pin 19 and by means of connecting lmks 25, 25 swings in a vertical lane so that its ink pad 26 will ink the 21 when the machine is clear of lumber and not being operated, as illus trated in Fig. 6. It is here noted that the pin 19 pivotally connects'the ink carrier to the die carrier and also connects the links 17 to these. arts. Lug 27 of ink carrier 24- is connecte through links 25, to one arm trip arm 30 in a pendentposition to en-' 'gage the lumber, whichlever swmgs on spindle 18. Shoulder 31 on plate 4 supports parallel links 17,-17 when the machine is lot and the die carrier are bothpivoted by the same pin (19), and hence osci lation of both take place onthe same center, whereby the The operation is as followszThe log of "wood, moving lumber or otherarticle to be contacting with the end of trip arm 30. Figure 1. B means ofarm 28 the inking the die carrier, whic marked advances towards the machine, first die is pulled upwards out of the path of the advancing lumber so that the latter can freely contact with the die 21. Fi 2. By reason of toggle arms 15, 16 and t eir connection with the weight bar, the die is forced ositively into the end of the lumber as the atter advances against the resistance of the weight, the spring 23 and of other moving parts of the machine. After the die has marked'the lumber, the further movement of the lumber turns the die carrier upwards. b thus causing the colla se of toggle arms and the release of the wei t from pressing upon then floats freely on the lumber until the latter is clear of the ma chine. Fig. 3. After the lumber has assed the parts are restored to their norma positlons.

. The position of the die can readily be adjusted vertically b loosening stud 8 and pin 5, thus allowin p ate4 to be movable vertically. Upon o taining the desired position,

7 the plate v4 can be again fixed by the same means.- B this means the marking device adjuste to different thicknesses of lum- The terms and expressions which I have em loyedrare used as terms of description and? not' of limitation, and I have no intention, in the use of such terms and ex ressions, of excluding any equivalents o the features shown or descri or portions thereof, as various modifications are possible within the scope of the invention claimed.
