MATRIX-CI-IANNELING MACHINE.

Specification of Letters Patent.

Patented Nov. 9, 1909.

To all whom it may concern: I

Be it known that I, HORACE A. REYNOLDS, residing at Woonsocket, in the county of Providence and State of Rhode Island, have invented a certain new and useful Improvement in Matrix-Channeling Machines, of which the following is a full, clear, and exact description.

A certain type of matrix has a channel in one side which extends from the top to the bottom thereof, such a matrix being shown in Fig. 6. These matrices must be of many different thicknesses at their edges to correspond with the different widths of the character depressions therein. But it is essential that the channeled part of all matrices shall be of the same thickness. Obviously therefore, the channels will be of different depths in matrices of different thicknesses.

The object of the present invention is to provide a machine in which thesechannels may be rapidly and exactly cut in the various matrices.

In the drawings which show the invention embodied in the best form known to me, Figure l is a side elevation partly broken away and sectioned. Fig. 2 is a plan view. Fig. 3 is a plan view of a part of the machine, partly broken away and sectioned, when the magazines and other parts secured upon the bed plate have been removed. Fig. 4 is a sectional end view on line 44., Fig. 1. Fig. 5 is a sectional end view of a certain part of the machine in the plane indicated by line 55 of Fig. 3; and Fig. 6 is a perspective view of a matrix having a channel cut in the machine.

Referring to the parts by letters, A represents a bed plate in whose top surface a channel a is cut,the width of said channel being equal to the width of a matrix, and being of a suitable depth to serve as a guide for matrices which are pushed along therein. Over this channel, near one of its ends, is a feed magazine B adapted to contain a pile of matrices M resting upon their sides; and D represents a receiving magazine secured above the other end of said channel. The bottom of the magazine 13 is held at such a distance above the channel that a push bar 0 may push out of said magazine and along channel a, the lowest matrix therein. The magazine D is sustained at such a distance above the said channel that the matrices may be pushed under its lower end, and over the vertically movable plunger F.

A slide 0 is movable in a suitable guide way H. The push bar 0 is fixed to it. A

pin 0 is adjustably secured to this slide.

zine D.

Attached to the sides of magazine D are two spring arms I having fingers z secured to their lower ends which project into said magazine as shown in Fig. 1, the lower surfaces of said fingers being beveled. When a matrix has been moved over the plunger F which is directly under the magazine D, this plunger is moved upward carrying the matrix upward. The matrix engages with these bevel surfaces of the fingers thereby spreading them apart and passing them; whereupon, the fingers spring inward again below said matrix whereby it and all of the other matrices in the magazine are sustained. This plunger is moved downward by a spring f and is moved upward periodically by a pivoted lever N to which is attached a pin 71. adapted to be engaged by a beveled block is attached to the rotating disk K.

The two magazines are fastened together by cross bars P P so as to form a rather rigid frame work. The vertically movable frame E lies between these two magazines and is provided with grooves in its vertical ends which embrace the said magazines, whereby saidframe is guided in its vertical movements. A screw T which is rotatably mounted in the cross bar P screws to this frame and thereby furnishes means for its vertical adjustment so as to adapt the mechanism to'beused in matrices of different thicknesses. The head of this screw by engaging with the top of said cross bar limits the downward movement of the frame E. A spring 25 surrounding the shank of the screw is compressed between the under side of the cross bar P and the top bar of the frame E, and yieldingly presses said frame downward as far as the screw T allows it to go. The functions of this frame are to prevent more than one matrix from being pushed out of magazine B by each forward movement of push bar 0; and also to hold the matrices down on the bottom of the channel a. By manipulating screw T the position of this frame is adjusted so that it will perform these functions irrespective of the thickness of the matrices being operated upon. Pivoted to one side of this frame is a spring-actuated dog V having a rather sharp lower edge which engages with the matrices as they are being pushed along in channel a, the matrices sliding under said dog as they are so moved. The spring 1), however, tends to push the dog down firmly against the tops of these matrices so that, when the slide C, having moved a matrix under said dog, recedes, this dog will bite into the top of the matrix and thereby prevent any recession thereof. A spring-actuated presser-foot S is also mounted in this frame E and it bears upon the top of a matrix and guides it under the lower edge of the magazine D. The lower face' of this presser foot is beveled upward toward the advancing matrices so that they will certainly pass under it and be thereby guided under the lower end of the adjacent leg of the frame E. Since this presser foot and the dog V are both carried by the vertically adjustable frame E they will always be in the position to act in the manner and for the purpose specified, irrespective of the thickness of the matrices being operated upon.

The channel is cut in the matrices by a milling cutter Qinounted upon a shaftg, which shaft has its bearing in arms r which project from the vertically adjustable block R. This block has vertical grooves in its vertical edges which receive fixed tongues 10 on a standard V and therefore guide the block. This block is adjustable vertically by means of a screw Y whose shank-is rotatively mounted in a flange 1* attached to this block; and the screw, which cannot move endWise in its bearings, screws into a part of a fixed standard V. A set screw Z screws through this standard against the screw Y and thereby looks it. The adjustability of this block R is required because milling cutters will not always be of the same diameter, especially after they have been sharpened several time, and it is required that the thickness of the channeled part shall always be the same.

In the operation of the machine a stack of matrices will be put into magazine B, and then the machine will be set in operation. One by one these matrices will be pushed from this magazine by the push bar 0 along channel a and under the cutter Q which mills the channel therein. The recession of matrices, when the push bar 0 recedes, is prevented by the action of the pawl V. Ultimately the matrices are pushed beneath the receiving magazine l and are pushed, one by one, up into said magazine by the plunger l The mechanism which Fig. 5 is particularly designed to show, is a safety stop device. The gate Y is located at the delivery end of the channel a, and serves as a stop against which a finished matrix engages when properly positioned beneath magazine D. It is held in operative position by a spring latch Z whose beveled inner end engages in a notch in the side of the gate. This latch will hold the gate in place against ordinary and expected pressure; but if, for example, a matrix when pushed up into the magazine D is not caught by the spring lingers I, and drops down into the channel, this matrix will, when push bar is next moved forward, be pushed along the channel past magazine D. In so moving it is pressed against the gate hard enough to release the latch and allow the gate to swing on its pivot out of the way.

Having described my invention, I claim 1. The combination of a bed plate having a channel in its top face, a cutter rotatably supported above said channel, a feed magazine supported above said channel with its lower edge a suitable distance above the bottom of said channel, a reciprmatiug push bar moving backward and forward in said channel under said magazine, a verti(;'.all v movable frame E, a spring pressing said frame downward, adjustable means for limiting said downward movement, and the spring actuated dog V carried by said frame and located between the cutter and said magazine.

2. The combination of a bed plate having a channel in its top surface, a. feed magazine supported over one end of said channel, a receiving magazine supported over the other end of said channel, a reciprocate ing push bar operating in said channel beneath the receiving magazine, a cutter rotatably mounted over the channel between said magazines, a vertically movable frame having two depending members whose lower edges are over said channel and close to the respective magazines, a spring which yieldingly presses said frame downward, adjustable means for limiting said downward movement, a spring actuated dog V pivoted to one member of said frame between the cutter and feed magazine, a. spring actuatet l presser foot supported on the other member of said frame between the cutter and the receiving magazine, a vertically movable plunger located under the receiving magazine, and mechanism for effecting properly timed movements of said. push bar and plunger.

3. The combination of a bed plate having a channel in its top surface, a feed magazine supported over one end of said channel, a receiving magazine supported over the other end of said channel, a reciprocating push bar operating in said channel beneath the receiving magazine, a cutter rotatably mounted over the channel between said magazines, a vertically movable frame having two depending members whose lower edges are over said channel and close to the respective magazines, a spring which yieldingly presses said frame downward, adjustable means for limiting said downward movement, a spring actuated dog V pivoted to one member of said frame between the cutter and feed magazine, a Vertically movable plunger located under the receiving magazine, mechanism for efiect-ing properly timed movement of said push bar and plunger, a movable gate normally proj ecting across said channel, and a latch yieldingly holding the gate in position.
