PLANING AND MATCHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 584,302, dated June 8, 1897. Ap lication filed September 4, 1894. Serial No. 522,042. (No model.)

To aZZ whom it may concern:

Be it known that we, GEORGE W. BUGBEE, residing in Delhi, and FREDERICK DANNER, residing in Cincinnati, in the county of Hamilton and State of Ohio, citizens of the United States, have invented a certain new and useful Improvement in Planing and Matching Machines, of which the following is a specification.

Our invention relates especially to that class of planing and matching machines in which a board is fed through the machine on edge, the feeding-rolls being placed in a vertical position. In machines of this kind the cuttermandrel is usually provided with two sets of cutters, one set of which is usually for the purpose of tonguing one edge of the board, the other for grooving the other edge. The machine as heretofore constructed was provided with a stationary fence between the two outter-heads against which the stock was fed through the machine. hen stock of different thicknesses was being operated upon, it was necessary heretofore to change the position of the cutter-heads on their mandrel or, if bits were being used on a cutting-cylinder, to change the position of the bits on the cylinder, which necessitated stoppage of the machine and required considerable time in making the adjustment. I/Ve obviate the objections to the old method by means of our new improved device, which enables the adjustment for different thicknesses of stock to be readily and quickly made while the machine is in operation.

Our invention consists in a fence which can be expanded or contracted in width to accommodate itself to different thicknesses in material operated upon and in the various parts and arrangement and combinations of parts hereinafter more particularly described and claimed.

In the drawings, Figure 1 represents a view in perspective of our new improved machine; Fig. 2, a central longitudinal section as indicated by the line 2 2, Fig. 3; and Fig. 3, a central transverse section of the same as indicated by the line 3 3, Fig. 2. Fig. 4 represents a sectional plan view of the fence on the line 4 4, Fig. 1. Fig. 5 is a plan detail showing the mode of pivoting the feed-shafts; and

Fig. 6, a section of the same on the line 6 6, Fig. 5.

A is the frame of the machine, and 13 its table.

C is a mandrel on which cutter-heads 0o 00 are placed.

D and D are vertical feeding-rolls mounted on shafts d d, driven by gears 01 d meshing with pinions cl (1 mounted on shafts (1 d journaled in bearings d d and carrying at their upper ends spurqvhcels d (Z which engage with pinions (Z d secured to a shaft (Z14, mounted in bearings 61 (Z and carrying an operatingpulley d, driven by means of a belt from a suitable source of power. The shafts d d are supported in steps or boxes (Z supported on pivots c1 mounted on yokes c1 bolted to the frame of the machine, as shown in Figs. 5 and 6. The purpose of attaching these steps or boxes pivotally is to allow a sidewise adjustment of the rolls D D, which is accomplished by means of handwheels (Z 61 and the rolls are given the necessary pressure by means of suitable springs 01 in boxes (Z The rolls D D are preferably slightly rounded and may be fluted or ribbed, the ribs being preferably angled on the face of the rolls that is to say, the upper end of the flutes or ribs on the rolls, when they present their inner face to the adjustable fence, are in ad Vance of the lower end of the flutes or ribs, thereby giving the necessary downward lead to the board and forcing it against the table and cutter-heads.

The mandrel C is mounted in bearings c 0, supported on plates 0 c adjustably secured to the frame of the machine. The bearing a is removable and can be slipped off the mandrel by unloosening the bolt 0 to enable dif-' ferent or various cutters to be placed on the mandrel. The mandrel is secured against endwise displacement by means of collars c c at either end of the bearing 0. Collars 0 which can be made of various thicknesses, are adapted to be slipped over the mandrel so as to bring the cutter-heads to the desired position thereon, and the cutter-heads and collars are fastened on the mandrel by means of anut Power is applied to the mandrel by means of a suitable driving-pulley c E is a shaft carryinga hand-wheel e for operating the same and spur-wheels e e, meshing with gears 6 6 carrying ad j usting-screws F is a fence which consists, preferably, of

two parts I F which are adapted to be ad'- justed to and from each other, thereby varying the thickness of the fence and consequently the guiding-faces thereof relatively to each other. ing barzF isplaced, provided with an inclined face or wedges ff, which take against abutments or faces f f on :the parts F F The sliding bar is provided at one end with a threaded socket f into which a hand-screw f provided with a hand-wheelf takes. The hand-screw takes through a plate f which spans the :two parts of the fence and is provided with a collar f which, with the hub on the hand-wheel f ,-prevents an endwise movement-ofthe screw when it is turned, thereby insuring a corresponding movement of the adjusting-bar. The plate f is provided with slots f, through which bolts f passinto the two parts of the fence, respectively, which bolts may be drawn sufficiently tight to prevent play and at the same time allow the movement of the parts while they'are being adjusted. The slidingbar F is provided with a tonguegf which takes into a groove Z1 on the table B and is also provided-with slots f f through which bolts f f pass into the table-B ofthemachine. These bolts are preferably drawn sufficiently snu g-to give the necessary firmness to the bar, but allow its:adjustment. The bar is also provided with a slot f, through which a bolt f passes, the latter'being provided at one end with a head f and at its other a nutf Springs f f take about the bolt f 'in recesses f f respectively, and forcevthe two parts of the fenceltogether. The fence is also provided with rolls f f 'Thefparts of thefence are provided, respectively, with slots f f. Bolts f f pass through'the slots into the table 13 and-may be screwed down'firmly to hold the fence in place after-having been adjusted.
