JOIN ER.

SPECIFICATION forming part of Letters Patent No. 653,616, dated July 10, 1900.

Application filed March 3 1900. Serial No. 7,205. (No model.)

To all whom it may concern:

Be it known that I, DANIEL CEDERBERG, a citizen of Sweden, residing at No. 292 West street, Leominster, in the county of Worcester and State of Massachusetts, have invented new and useful Improvements in Joiners, of which the following is a specification.

This invention relates to improvements in woodworking machinery of the class generally termed joiners for the purpose of planing the edges of boards preparatory to matching or making glue-joints for the same, and it is carried out as follows, reference being had to the accompanyingdrawings,wherem Figure 1 represents a rear view of the improved machine. Fig. 2 represents an end View seen from X in Fig. 1. Fig. 3 represents atop plan view of Fig. 1. Fig. 4 represents a front view of the machine, and Fig. 5 represents a top plan View of the rotary planingtool.

Similar letters refer to similar parts wherever they occur on the different parts of the drawings.

In the drawings, A represents the base portion of the frame of the machine, having made integral with it a horizontal table-top B, provided on its upper side with a preferably V-shaped guide-rib O and a preferably flat guide rib or way D, on which the carrier E is longitudinally movable, as will hereinafter be more fully described.

The carrier E is provided on its under side with a longitudinal groove 6, adapted to receive the guide-rib O on the table-top B, as shown in Fig. 2. The carrier E is provided at its ends with upwardly-projecting brackets E E, to the upper ends of which is secured or made integral therewith a bar or beam E, through screw-threaded perforations in which are" screwed the adjustable clamping-screws F F F, as shown in the draw- 1ngs.

f f f are hand wheels or cranks secured to the upper ends of the screws F F F, as shown.

G G are the boards, which are placed on the carrier E and seen red firmly in position thereon by means of the clamping-screws F F, as shown.

In the upper portion of the bar or beam E" is made a longitudinal groove e, adapted to receive an upper guide-rib a, secured to or made integral with an overhanging arm on the upper ends of vertical uprights extend ing above the table of the machine-frame, as shown. v

In bearings in the frame is journaled the rotary vertical shaft h, to which is secured the knife-carrying block H, having secured to two of its opposite sides the knives or planer-blades H H, as shown in the drawings. To the lower end of the shaft h is secured a pulley h, to which a rotary motion is imparted by means of a belt I, leading from a pulley K, secured to a driving-shaft 7c, as shown in Fig. 1. In practice I prefer to so cure to said driving-shaft It a small pulley Z, from which leads a belt L to an overhead pulley L, secured to a shaft m, having secured to it a pulley M, from which leads a belt N to a pulley n, secured to a shaft 0, suitably journaled in bearings, as shown in Fig. 1.

In stationary bearings below the table-top B is journaled a screw-shaft P, working in a screw-threaded lug E secured to the under side of the carrier E, as shown in Fig. 1.

In practice I impart a reciprocating motion to the carrier E and the boards G held there on by means of a pulley O, secured to the shaft 0, and direct and cross belts O 0 leading from said pulley O to pulleys on the screw-shaft P, as is common in belt transmission for reciprocating a carrier and need not be referred to in detail.

Q is a vertical guide-plate adjustably secured to the table-top B, and it serves as a guide against the edges of the boards G pre paratory to being acted on by the rotary cutters H H after said boards have been clamped in position on the carrier E.

In practice I prefer to secure to the tabletop B on the opposite side of the rotary cutter a vertical guide-plate R, against which the edges of the boards are guided after be= 5 ing squared by the rotary cutters.

The operation of the machine is as follows: The boards to be squared on their edges are placed one on the top of the other on the carrier E, with their edges against the guide Q, after which they are clamped and secured in position on said carrier by means of the clamping screws F F, as hereinabove described. The machine is then set in operation, causing the cutter-shaft h, with its outter-blades, to rotate and the carrier E and boards held thereon to move in the direction of the arrow shown in Fig. l, and in so doing the rotary cutter-blades H H are brought in contact with the edges of the boards, causing them to be squared suitable for matching or making glue-joints, as may be desired.

After the entire lengths of the boards have traveled by the rotary cutter and been shaped and squared the motion of the carrier and boards attached to it is reversed, either by hand or any well-known automatic shipper device, so as to return the carrier to its original position, after which the boards are released and reversed in position on the carrier and the operation repeated for squaring the opposite edges of the boards, and so on during the operation of squaring successive boards for the purpose stated.

What I wish to secure by Letters Patent and claim is- The herein-described joiner, consisting in combination, of a frame having a table provided with horizontal guides, standards rising above the table and provided with an overhanging arm having a guide thereon, a vertical cutting-knife journaled in the frame and with its operating-cutters above the table, a carrier provided with guideways in its top and bottom to cooperate with the guides on the table and the overhanging arm of the frame, clamping-screws arranged in the top of said carrier and adapted to clamp a series of boards in the-carrier, and means for causing said carrier and the boards clamped therein to travel in front of the cutting-knife, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

DANIEL OEDERBERG.
