This invention relates to wood cutting machines and has for an object the provision of a. machine for cutting circular or semi-circular grooves, the invention being especially designed for cutting grooves in the ends of wood gutter sections for splicing the sections.

Wood gutter material may be obtained in lengths of from forty to fifty feet but is very expensive, the cost being materially increased by transportation, as two cars are required to accommodate lengths ofthis character. The cost of long lengths of gutter sections therefore is increased considerably over the sixteen to twenty foot lengths.

The present invention therefore has for an object the provision of means for splicing the gutter lengths. so that not only the sixteen to twenty foot lengths may be economically employed,,b,ut much shorter lengths may be cheaply and efficiently joined so that none of the material may be wasted.

Another object of the invention is the provision of a machine by means of which the lengths vmay be quickly and economically spliced. Y

lWith the above and other objects in view, the invention further includes the following novel features and details of construction to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

Referring to the drawings in detail wherein like characters of reference denote corresponding parts, the reference character 10 indicates a pair of brackets which maybe of suitablesize and shape to which are provided upon one of their faces spaced shoulders 11, defining a guide groove for a hanger 12. The brackets 10 are'of light construction as are also the hangers 12, and each of these hangers carries at its lower end a collar 13 for the reception of a shaft 14. The hangers are providedwith elongated slots 15 for the pas- Sage of bolts. 16 carried by the brackets 10. Right angularly disposed lugs 17 extend from the upper ends of the hangers and are provided with threadedopenings 1.8 for the The screws 16. serve to hold the hangers against the faces of the brackets 10,. whlle the screws 19 provide means for adjusting the hangers-with respect to the bm S- Mounted within the collars 13 of the hangers-is a shaft 20 which is provided with 0 13 engage, so that the hangers are spaced This shaft has its opposite ends threaded as shown. at 21 and slidingly mounted upon the shaft is a cutter arm 22, the s latter being provided. with a sleeve 23 which receives the. shafts. A handle 24 is provided uponthe arm 22 so that the. arm may beconveniently rotated upon the shaft 20.

The cutter arm: 22 carries spaced cutters 25, whose blades 26 extend inward toward the brackets 10. These cutters are adjusta- -ble longitudinally of the arrn22 through the order to feed the cutters toward the brackets 10, a nut 29 is threadedly engaged with the shaft. This nut has slidable therethrough a headed pin 30 which is adapted to enter a socket 31 provided in the end of the sleeve 23. When the par-ts are in the position shown in Figure 3 of the drawings, rotation of the arm 22 will move the cutting blades longitudinally of the shaft.

In order to clamp the work in position,

there is provided plates 31 which are adapted to be arranged in clamping engagement with opposite sides of the work. These plates are notched as at 32, to. engage over ribs 33 provided upon the brackets 10. The plates may thus be adjusted relatively. The outer ends of the brackets have depending therefrom lugs 34:, and these lugs are provided with threaded openings for the passage of clamping screws 35 and 36. The screws 35 are provided with handles or wheels 37, while thescrews 36 are provided with heads 38 and lock nuts 39. I

In the drawings, the invention is shown as arranged for cutting grooves in the ends of wood gutter sections WV so that these sections may be spliced. The grooves are adapted to receive curved metal connecting elements 40 which are held in place by any suitable adhesive, such for example, as white lead. The

gutter is clamped upon a table or other support l0 by means of a clamp 41. One end of this clamp is notched to removably engage the shaft 20, while the other end of the clamp carries a clamping screw 42 which engages the bottom of the table or support 40. The clamping screw 36 is adjusted so as to position its plate 31 properly in accordance with the width of the gutter and this screw is then locked in place by the nut 39. The other plate is adjusted against the opposite side of the gutter sufficiently to hold the gutter in place without injury. The hangers 12 may be then adjusted so that the shaft 14: will be concentric with the inner surface of the gutter, and the cutters 25 are then adjusted so as tobring the cutting blades 26 in proper position for the work.

' The feed nut'29 is then engagedwith the sleeve of the cutter arm and the latter is rotated to feed the blades 26 into the work. After the groove has reached the desired depth, the feed screw may be disengaged from the sleeve of the cutter arm an threaded outward, and the cutting blades may then be withdrawn from the groove.

By threading opposite ends of the shaft 20, the cutters may be positioned at either end of the shaft so that the set screws 36 may at all times be positioned upon the same'side of the gutter. This is especially desirable where the gutter is of the Ogee type. In Figures 5 and 6, the brackets 10 are provided with outwardly extending arms 42. These arms have adjustably mounted thereon collars 4:3 and 44 which have depending therefrom lingers 45 for engagement with opposite sides of the gutter W. One of these collars carries a set screw 4:6 and this collar is adapted to be set in position after the manspacedbrackets, a shaft disposed transversely of the brackets, a cutter arm rotatably mounted upon the shaft, a cutter carried by said arm and disposed parallel with the shaft,

means to feed the cutter longitudinally of the shaft when the cutter arm is rotated,

means mounted on said brackets to clamp the work in position,rmeans to center the shaft with respect to the work, and means to adjust the cutter with respect to the work and radially with respect to the shaft.
