To all lwhom it may concern:

Be it known that I, ROBERT I-I. MELLOWN, a citizen of the United States, residing at Coaling, in the county of Tuscaloosa and State of Alabama, have invented a certain new and useful Improvement in Lumber- Registers, of which the following is a speciiication.

My invention relates to a new and useful improvement in lumber registers, and has for its object to provide an exceedingly simple and eective device of this character whereby a record may be kept of lumber in squjare feet, board measure, as it passes through the planer, in this way doing away with the expense of hiring a tally man.

A further object of my invention is to increase the output of dressed plank of odd size as the manipulator may continue run* ning the planer until a suilicient amount of lumber has been planed to lill the order for odd size plank, in this way saving the time it would take him to stop and count up how many feet he had planed, as he can see it at all times upon the register. When enough of this odd size lumber has been planed to fill the order the planer may be stopped or the person running the same may shift to other work, thus saving both lumber and time.

With these ends in View, this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, I will describe its construction in detail, referring by letter to the accompanying drawing forming a part of this specification, in which- Figure l is an end view of my improved lumber register. Fig. 2, a plan view thereof. Fig. 3, a section at the line 3-3 of Fig. l looking in the direction of the arrow. Fig. 4:, a section at the line 4 4 of Fig. l. Fig. 5, a section at the line 5 5 of Fig. l, and Fig. 6, a side elevation of one of the friction wheels.

In carrying out my invention as here embodied, A represents the planer bed plate, to

which is fastened the brackets B, by means of the bolts C. In the brackets B is journaled the frame D, by means of the trunnions E, and in this frame is a hole F,

lthrough which passes the shaft Gr, on the outer end of which is secured the wheel I-I, the periphery of which is provided with the teeth I, which pass through a slot J in the planer bed plate A.

K denotes a projection formed with the frame D provided with a rest L and a lug M, said projection adapted to pass through the opening N formed in the bed plate, and attached to the lug M is a spring O, the oppo-site end of which is fastened to a lug P formed with theunder side of the bed plate. When the projection K is drawn upward by the spring O the rest L will come in Contact with the bed plate A, thus preventing the toothed wheel H from rising any higher, or that part of the mechanism on the other side of the bed plate from being lowered.

The shaft G is provided with a long keyway Q and the shafts outer end is journaled in the bearing R, in which is also j ournaled the end of the shaft S and also having a key-way Q. On the outer end of said shaft is secured the pinion T, said pinion meshing with the gear U, fastened to the shaft V journaled in suitable brackets, and having mounted thereon the worm gear W, which operates t'he register or counter A.

Formed with or secured to the frame D is a track B, on one side of which may be placed a scale, with which the pointer C carried by the carriage D will register. In the arms E and F of the carriage D are mounted the friction wheels G and H, each provided with a friction material I', which frictionally engages with the disk J said disk resting upon the rollers K mounted on the shaft L', the ends of which are movably mounted in the frame D by means of the lugs l and beneath the ends of said shaft are placed the compression springs N.

O is a bolt passing through the disk J and the frame D, on the end of which is threaded the nut P whereby said bolt may be drawn downward or moved upward as the .case may be, which will move the disk J in the same direction, and when being drawn down will do likewise with the rollers K mounted on the shaft L against the action of the compression springs l placed beneath the ends of said shaft L.

The friction wheels G and I-I are each provided with a key Q which registers with the key ways Q formed in the shafts G and S. With the upper portion of the carriage D is formed the lug R having internal threads S, into which is threaded the screw T', so that when the carriage D has been i moved along the track B' to the desired position, the screw T' is turned in the lug R' until it jams against the track B', which will hold the carriage in said position. To the frame l) is hinged the glass cover U' by means of the hinges V', said cover being held in its closed position by a suitable latch V2, thus saw dust and other dirt will be kept from the delicate parts of the mechanism, and at the same time the register dial and the working parts may be seen.

In practice the lumber being worked upon will pass along the bed plate A resting upon the toothed wheel H, and as said lumber moves forward said wheel H will be revolved, thus revolving the shaft G which will do likewise with the friction Wheel H', and as this frictionally engages with the disk J said disk will be revolved and this will revolve the friction wheel Gr' which is splined in the shaft S, causing said shaft to revolve, on the outer end of which is attached the pinion T meshing with the gear wheel U, so that said gear wheel will be revolved, and as this is mounted on the shaft V said shaft will revolve, thus causing the register A' to be operated through the medium of the worm gear W.

While the lumber is passing over the bed plate A the teeth I of the wheel H sometimes encounter knots in the lumber and as these are harder than the rest of the wood the wheel H will be moved downward against the action of the spring O, which will move the frame I) upward again to its normal position, and when there is nothing at all upon the bed plate the spring O will draw the wheel upward until the rest L engages the inside surface of the bed plate A, at which. time the shaft G will be in a horizontal position.

When the carriage D' is moved to the right, that is, toward the bed plate the friction wheel H' will move nearer the periphery of the disk J', which will cause the disk J' to run slow and will cause the friction wheel G' to run slow, thus operating the register A' slower. Then the friction wheels G' and H' are the same distance from the center of the disk J they will be running at the same rate of speed, which will cause the register A' to operate moderately, but when the friction G' and H are moved to the left the friction wheel H being closer to the center of the disk J' will cause the disk J' to revolve rapidly, thus causing the friction A wheel G to revolve more rapidly, thus op erating the register A very fast.

The registering of the lumber is done in the following manner :mSay the disk J' is thirty-six inches in circumference, the fric- '7 :tion wheels G' and H' are three inches in circumference and the toothed wheel H twelve inches in circumference, then if the friction wheels G' and H' are set an equal distance from the center of the disk when the toothed wheel H has traveled one linear foot, the shaft S will have made one revolution causing the register or counter A to register' one, which will be one square foot, board measure, for a one inch by twelve inch boa-rd.

For a board one inch by one inch the friction wheel G' will beset to that point on the disk J' which will equal a three inch circumference on said disk, at which time the friction wheel H' will be at that point on the disk where it is thirty-siX inches in circumference. For a board twelve inches by twelve inches the friction wheel G' will be set on the disk at that point where when traveling it will be thirty-six inches in circumference and the friction wheel H' will be at that point where it is but three inches in circumference. In the latter case the toothed wheel H when traveling one linear foot the friction wheel H' will have caused the disk J' to revolve once, which will cause the friction wheel G 'to revolve twelve times thereby registering twelve square feet on the counter A'. Between these two extremes would be found the different points which willl count up the number of square feet in any size lumber from a one inch by one inch to a twelve inch by twelve inch.

Of course I do not wish to be limited to the exact details of construction here shown as these may be varied within the limits of the appended claims without departing from the spirit of my invention.
