CLEAT-NAILING 'MACHINE.

SPECIFICATION forming part of Letters Patent No. 600,685, dated March 1 5, 1898.

Application filed July 16,1896. Serial No. 599,407. (No model.)

To all whona it may concern:

Be it known that I, I/VILLIAM S. DOIG, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in (Heat-Nailing Machines, of which the following is a specification.

My invention relates to machines for securing cleats placed over depressed box-covers by nailing the same with nails driven through the cleats obliquely as to the inner surface of the sides of the box; and the invention consists in the construction and novel arrangement of parts whereby two cleats on opposite sides of the box are simultaneously nailed at one operation.

Figure 1 is a front elevation of my machine for nailing cleats for fastening covers on boxes. Fig. 2 is a side elevation of the same with a portion of the frame broken away. Fig. 3 is an elevation of a portion of the machine. Fig. 4 is a plan view of presser-plate employed. Fig. 5 is a partial section and partial elevation showing the mechanism for driving nails. Fig. 6 is an enlarged view of self-adjusting guide. Fig. 7 is an enlarged view of self-adjusting guide and chuckingplates. Fig. 8 is an enlarged view of one of the links connecting the cross-head and nail-punches. Fig. 9 is a sectional view of box-support or table A with pivoted platen A in position. Fig. 10 is a plan View of the same, showing register-pad 3 on platen A with stops 6 e and handle 6, showing the arc of the circle through which the platen is moved. Fig. 11 is an enlarged View in section of the side, top, (or bottom,) and cleat of a box (the manufactured product of this machine) with a nail f shown in the position in which it has been driven by the operating mechanism thereof. Fig. 12 is a perspective view of a box with four cleats of the top (or bottom) nailed in position. Either pair of cleats,as0c and 00, represent the product of one nailing operation.

A A are the side frames of the machine, firmly bolted on a base or foundation at the bottom and secured in a firmmanner by a cross-girth on top, also by a cross-girth carrying the shaft A and also by the fixed angular guide-form Ofiwhich also acts as a cross-girth,

the whole making the main frame of the machine solid and rigid, and the construction having forits purpose the leaving of an open passage through the machine between the top of the box-support or table A and the lower edge of the self-centering guides D D to permit the box operated upon to be introduced at the front of the machine and, after being nailed, to be delivered through the rear, thus greatly increasing the working capacity of the machine.

A is the drivingshaft, upon which is mounted a pinion b engaging witha gear Aiwhich also forms a crank (1 Loosely mounted on the shaft A is a pulley A having a clutch mechanism A for engaging the shaft. These parts are well known and are fully described in my Patent No. 461,013, dated October 13, 1891.

p The gear A engages a gear A of the same diameter, on shaft A having suitable bearings in the frame of the machine. On shaft A is fastened the cam a, which works on a roller aflconnected with the box-supporting table A It will be readily seen that by each revolution of the gear A the cam a will be revolved and impart a reciprocating motion to the table A By the substitution of different cams the motion of the table A can be varied to suit any depth of box to be operated upon. The cam a is not only designed to impart a reciprocating motion to the table, but when the table is elevated thereby the cam during the remainder of its revolution forms a rigid support for the table, retaining it rigidly in position.

B is a vertically-reciprocating crosshead guided in the side frames A A and projecting through them. Motion is imparted thereto from the driving-shaft A through the medium of the connectingrods c extended downward to carrier B, guided in the side frames in the same manner as cross-head B, having a rectangular yoke co in which slides a block a having connection with the crank pin a on gear A On either side of the reciprocating crosshead are pivoted a number of pairs of links O (Shown in Figs. 2, 3, and 5.) In this case I use three pairs of links, but can use any number required. The links 0 are pivoted loosely on the cross-head and are carried up and down thereby. The lower ends of each pair of said links C are pivoted to the corresponding pair of nail-punches Each pair of links is deflected outward and downward from the perpendicular on opposite sides through the plane of reciprocation of crosshead B. The angle at which the links C and through them the nail-punches c are deflected is determined by the angular guideform 0 in which the nail-punches work. This position of the parts enables one to center the box-su pport directly beneath the crosshead, and thus to bring the cleats to be nailed parallel with the cross-head.

The angular guide-form O is rigidly fixed to and forms part of the main frame of the machine.

Rigidly attached to the angular guide-form C and extending in a right line therewith is a bar 0 G for holding the nail-boxes c c, which nail-boxes conform to the same angle and are in a right line with the nail-punches. Otherwise the construction of the nail-boxes is the same as described in my patent above referred to.

B is a presser-plate for engaging the top of a box to be operated upon and holding it and the cleats in position during the nailing operation.

The presser-plate B is a flat plate of steel beveled to fit against the inner face of the cleats and corresponding'to the outline of the cover of the box operated upon and fitted with recesses for the passage of nails, preferably suspended loosely from the cross-head by four round guiderods 1) through four guides 19' on the cross-head, in which they fit loosely, and on the upper end of each rod a nut may be used to regulate the depth at which the presser-plate shall hang suspended. Between the presser-plate B and the guides 19 on each guide-rod b a spiral spring 19 1s arranged and regulated by a collar attached to the rod b. The under edges of the presserplate are beveled on the four under sides to an angle corresponding with the exposed sur-' face of the cleat. The presser-plate is recessed at intervals, as shown in a plan view in Fig. 4, to permit the passage of the nails.

A is a table movable vertically between the uprights A A by means of the cam a, acting on the roller a, journaled in a hanger secured to the under side of the table A".

A is a rotary platen pivoted in the center of the table on the pin 1) and having thereon a registering-pad y, adapted to center the box on the platen. Said platen is provided with a handle e and stops 6 e, limiting the rotary motion of the platen to one-quarter revolution, as shown in Fig. 10.

D D are self-adjusting guides. (Shown in Figs. 2 and 3 in position in the machine and in Figs. 6 and 7 in detail.)

The guides D D may be fixed in any desired position by means of set-screws d and are mounted on brackets D so as to slide inward or outward. Springs 19 around the setscrews 01 allow the guide-plates to adjust themselves with equal pressure on both sides of the box to be operated upon. The guideplates are inclined downward and outward on theirinner faces, so as to allow the box to enter and to bring it into such position that the cleats to be nailed will be in proper alinement with their corresponding nail-punches.

The inner faces which come in contact with the surfaces of the box, can be faced with hardened steel and will then operate to clench any nails which in ayproject through the sides of the box.

Such being the construction of the different parts of my invention, I will now proceed to explain the operation of my machine.

In this machine in practice the nails are driven downward and outward through the cleat at right angles to the exposed surfaces thereof and obliquely into the sides of the box, thereby holding the cover in position. The cover is depressed within the sides of the box to the depth of the cleat, leaving the upper edge of the cleat flush with the top of the side piece against which it rests. Such boxes are used commercially for packing plug-tobacco.

In operation a box with a cover and cleats in place is mounted on the pivoted platen A (shown in Figs. 1 and 2) on the box-support A and the driving mechanism is started by clutch A in the usual manner. The cam on elevates the box-support or table and platen,

with the box thereon, until it engages the box between the self-adjustingguide-plates D D, which, acting thereon, clamp the sides on the exterior, so as to resist the pressure of the nails when driven, bringing the box into position and alinin g the cleats. The guides D D also form the anvil by which the nails are clenched. The upward movement of the box against the presser-plate B depresses the cover vertically to its proper position and the beveled under edges of the presser cause it to exert a pressure obliquely on the cleats, forcing them outwardly and against the interior surface of the sides of the box, holding them r15 firmly in place. This pressure is required to prevent the cleats from splitting during the nailing operation, the tendency to which is a practical difficulty which it has been found essential to obviate. As the table and platen start upward the cross-head starts downward, but moves at a lower rate of speed, the ratio of speed between these parts being fixed and determined according to the depth of the box to be operated upon and is controlled by the shape of the cam. The nail-feeding mechanism is so adjusted that the nails are delivered in the nail-pockets ready for driving during the movement above described. The cam a, continuing its revolution, first brings the box into position and then furni'shes a rigid support for the table and plates carrying the box and in conjunction with the guides D D and the presser-plate B holds it in position during the nailing operation as within a vise. The cross-head B completes its descent and causes the links 0 to force the punches 0 obliquely downward and outward, traveling through their respective guides on the angular guide-form 0 This movement of the punches brings them in contact with the respective nails in the corresponding nail-pockets. The nails are thus driven through the front and rear cleats and corresponding sides of the box. The crosshead then returns to its starting position, While at the same time the table returns to its starting position, thus completing the simultaneous nailing operation of two opposite cleats. The two remaining cleats are brought into position for nailing as follows: The platen is moved by means of the handle 6 until the handle comes into contact with the stop 6 in the position 6 shown in Fig. 10. The remaining cleats are then nailed, as above described and on the descent of the table to its normal position the completed box is passed through the rear of the machine while a new box is being placed on the platen.

The machine, it willbe seen, is operated through two trains of mechanism, the one operated by the reciprocatingcross-head B and the other by the cam c.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-
