4 Claims.
The invention relates generally to marking devices and primarily seeks to provide a novel, power driven machine structure for rapidly and efficiently marking bar stock so that when the stock is subsequently cut into small pieces incident to the manufacture of units of which valve, coupling or fitting elements, rings, sleeves, `collars or like elements constitute examples, said units each will have impressed thereon identifying markings assuring the purchasing public as to the origin or other standards of the product, material specications or end use designations.
It was the practice in the past' to hand mark bar stock for the purpose stated, as by daubing identifying colors thereon, but such practices caused trouble in the working of the stock in forging dies or automatic machines and have become obsolete. Machines have been provided heretofore for marking bar stock, but such machines have been limited in efficiency and popularity because of slowness of operation, lack of clearness and uniformity in the marking effected thereby, lack of adaptability to the marking of different types and sizes of stock, or due to the complicated nature thereof and resultant high cost and dii'lculty in handling. It is the purpose of the present invention to provide a simple and economically constructed machine in which all objectionable features of the nature stated are avoided.
In its more detailed nature the invention seeks to provide a novel machine structure of the character stated in which the bar stock to be marked is fed rapidly between marking rolls which preferably impress the desired marking along opposite sides or faces of the rapidly travelling stock, means being provided for yieldably pressing one said roll toward the other for applying yieldable pressure effective to compensate for any slight inaccuracies in the straightness or size of said stock.
Another object of the invention is to provide a machine of the character stated in which'is included means for adjusting the spaced relation of the marking rolls without disturbing the means for yieldably pressing one said roll toward the other.
Another object of the invention is to provide a machine of thecharacter stated in which the opposed marking rolls are flanked by two rotary supporting and driving rolls each opposed by a grooved and springv pressed roll, said spring pressed rolls being adjustable toward and from the Ydriving rolls without disturbing the pres- ,sure applying devices.
Another object of the invention is to provide a machine of the character stated in which the driving rolls and one of the marking rolls have spur gears secured thereto and an idler gear is interposed between and meshes with the marking roll secured gear and the gear attached to the driving roll at each side of said marking roll, driving power being applied to the gear connected train at the position of driving roll farthest along in the direction of feed travel of the .bar stock thereby to eliminate back lash and assure that both driving rolls will effectively drive the bar stock.
Another object of the invention is to provide in combination with the bar stock supporting and driving devices, novel means for registering the footage of bar stock marked in the machine, and means for adjusting the position of said registering .means incident to the adaptation of the machine for the marking of different sizes of bar stock.
With the above and other objects in View that will hereinafter appear, the nature of the invention will be more fully understood by following the detailed description, the appended claims and the several views illustrated in the accompanying drawings.

In the example of embodiment of the invention herein disclosed there are included a feed-in table or support, portion A, on which the 'bar stock is supported as it is being fed into the marking machine proper, generally designated B, wherein the marking means and also the stock moving or feeding means is incorporated, and the feedaway table or support, generally designated C, on which the bar stock is supported as it is being fed away after having been properly marked in the machine B.
The feed-in table or support A includes a pair of parallel space support beams 5, which are supported as at 6 on the frame of the machine proper B and by other suitable supporting standards (not shown). Between the beams are mounted a plurality of bar stock support rolls 1, and at spaced intervals certain of said rolls are provided with spaced guide collars 8, for properly guiding the bar stock to the feeding and marking devices in the marking machine. The guide co1- lars are .adjustablysecured on\therolls 1, as at 9, so that the lateral spacing thereof rnayvbe varied to accommodate bar stock of different sizes, assuming, of course, that the shape of bar:-
stock illustrated in the drawings is maintained.
The machine proper includes a support frame comprising transverse table.=beams:. II), and sup'- porting standards I I. Themachine frame-also includes transverse suport extensions I2 whereon is mounted a driving unit includinga,motor I3. The drive shaft I4 of the motor is'coupld with a speed control gearingmunit I5 of any approved type. The drive or power out-put shaft I6 of the. unit.

The gears 40 intermesh in the manner clearly illustrated in Figure 1 of the drawings.
The end-most shafts 36 are equipped with bar stock supporti-ngroll extensions' 4I, and the cenltral"slfr'aftrv 36-h'as a marking 'roll 42 removably secured thereon as at 43. See Figure 2. The marking roll is equipped with a marking periphery 44, and it is to be understood that the marking rolls may be selectively mounted so as to -provideithe particular type of marking desired during azparticul-ar setup of the machine.
At theffarfend'of the machine, that is at the endltowardwhichlthe bar stock is fed, the shaft 36'is extended as at 45 and is coupled as at 46 with vfthe/"drive shaft or power out-put connection I6.

Thus the Wheel 58 will move up approximately 15; of an inch when the driven bar stock first engages it. This providesfor a little movement of the wheel to compensate for slight inaccuracies in the straightness or size of the bar stock. The wheel is held in engagement with the bar stock by its own weight and the weight of the footage registering device 53.
The feed-away table or support C comprises a pair of parallel spaced support beams 59 which are supported as at 60 on the marking machine framing and upon suitable support standards (not shown), and these beams also mount a plurality of bar stock support rolls 6| in the manner illustrated in Figures 1 and 2 ofthe drawings.
In adjusting the machine for marking a particular size and shape of bar stock, the bar stock which is to be marked is inserted between the idling rolls I and the driving rolls 52, and the screws 23 associated with the idler roll-carrying slide blocks 22, are turned until the idler rolls 5l contact said bar stock. The screws 23 are then given an extra turn to cause the idler rolls 5| to grip the bar stock under spring pressure. This extra turn of each screw causes the rectangular bars 21 on top of the upper ilanges I1 of the channel beams I1 to rise slightly from the channels in the manner clearly illustrated in Figure 2. This type of grip on the bar stock permits slight variations in the bar stock size without aiecting the penetration of the high grade hardened steel marking dies 49, 42 because the spring pressure maintaining the rolls 5I in contact with the bar stock remains substantially constant for slight variations in bar stock size. It is to be understood, of course, that the upper or adjustably mounted marking die 49 is adjusted in the same manner.
When the machine has been adjusted as described above, bar stock to be marked is fed over the feed-in table A, properly guided by the spaced collars 8, and is inserted between the opposing idler and driving roll sets 5|, 4I and between the opposing marking dies or rolls 49, 42, so as to be marked on both sides, that is on and along the top and bottom surfaces by said dies. The marking on the bar stock is such that when the stock is cut and machined into tting, valve or other unit elements, at least one unit of marking will appear on each element or piece. The frictional engagement between the rolls 4l and the bar stock serves to drive the bar stock through the machine while the desired markings are being indented thereon.
The simplicity of operation and set-up are outstanding features in the marking machine herein described. It requires but a moment to change the high grade hardened steel marking dies or rolls or to replace the idler and presser rolls 5l so as to change their shape and size according to the type of stock to be marked. It will be obvious also that the speed of operation of the machine can be varied at will.
It is understood that the @tails of construction of the cooperating parts can be variously changed without departing from the spirit and scope of the invention, as dened in the appended claims.
