This invention relates to an improved .plug cutting machine primarily designed for use in cuttings plugs for plugging knot holes in lumber used for commercial purposes, such as the construction of burial caskets.
Another objectof my invention is to produce a plug'cutting machine of the above character embodying a tubular saw, anda spring pressed plunger provided with a head 7 to force the plug cut from the lum- H acting her out of the opening created in the cutting operation of the saw, r i
It is a further object of the invention to produce a machine of the above character which is simple in its construction, durable and reliable in operation and may be'constructed at comparatively small manufacturing cost.
VV'th the above and other objects in view as will become apparent asthe description proceeds, the invention consists in certain ments of the parts that I shall hereinafter fully describe and claim.
For a full understanding of the invention, the following 16 1 reference is to be had to 'scription and accompanying. drawings, in
Fig. 2; Fig. 1 is a detail the saw. Fig. 5 is a detail perspective view. I
Figure 1 is a side elevation of a plug cut ting machine embodying the present invention; Fig.2 is an enlarged vertical section; Fig. 3 is a section taken on the line 3-3 of of the collar- In the construction of burial caskets and similar manufactures in which cloth covered or veneered lumber is used, the lumber con tains manyimperfections and-in many instances is so greatly weakened by numerous knot holes and similar defects that it cannot be used. Thus considerable waste results.
It is the principal object of my invention to produce a simple and highly eflicient machine for quickly cutting plugs to be secured by glue or similar adhesive in the holes of the lumber, whereby waste of the material i Specification of Letters Patent. 7

is minimiZed,-and considerable economy in the manufacture of burial caskets and slmll'ar articles effected.
Having thus outlined theprimary purpose of'my'invention, I-Wil]. now proceed with a detail. description 0f,-;its construction and operation. j r 7 Referring in detail to the drawings, 5 designates a bracket which is secured to an upright orother stationary support, said bracket including thelower and upper arms 6 and 7 respectively. The upper arm of the bracket is formed with a broad supporting plate 7' whereon the operating motor 8 is disposed. A motor shaft 9 is coupled to the upper end of a vertically disposed shaft 10, the opposed ends of the motor shaft 10 being provided with disks 11 and 12 respectively betweenwhich the fiber disk 13 of paper or other material is arranged, said latter disk being provided with. cylindrical sockets or recesses 14 to receive the pins or studs 15 carried by the disks 11 and 12. The vertical shaft 10 is mounted to rotate in a bushing 16 arranged in the outer end of the upper bracket arm 7, and suitable ball bearings indicated at 17 support the vertical shaft, said bearings being arranged above and below the bracket arms 6. i
The lower end of the shaft 10 is enlarged and provided with exterior screw threads 18 to receive the interior threads upon the upper end ofa hollow mandrel 19. This mandrel extends through a bushing 20 arranged in the lower bracket arm 6. The outer face of said bushing tapers longitudinally from its lower to its upper end, the bracket arm and semi-circular yoke or collar 22 being provided with similarly tapered recesses 21 through which said bushing extends. The bushing is exteriorly a lock nut 23. The is provided with a ring or annulus one of its ends which receive the threaded to receive collar 22 24 upon lower larger end of the bushing 20. The
lower end of the mandrel 19is exteriorly threaded as shown at 25 to receive a clamping nut 26, the later explained.
Within the hollow mandrel 19, a tubular saw 27 is arranged, the'tube closely engaging the wall of the mandrel and extending downwardly beyond the lower end thereof.
purpose of which will be The lower end of this tube is provided with spaced open ended slots 28 whereby a series of tongues 29 are formed. The lower end
