MARKING MACHINE.

Application led December 9, 1922. Serial No. 605,803.

My invention relates to the classI of machines that operate to automatically mark or brand articles with characters of any desired sort, and an object of my invention,

among others, is to provide a machine of this type that shall automatically, efficiently and rapidly perform the operations required of it.

One form of machine embodying my invention and in the construction and use of which the objects herein set out, as well as others, may be attained, is illustrated in the ac'companying drawings, in which-.-

Figure 1 is a top view of my improved marking machine.

Figure 2 it a view in front elevation with the driving shaft broken off.

Figure 3 is an end view looking at the left hand end of the machine as shown in Figure 2. v

Figure 4 is a view, scale'enlarged, through a portion of the machine on a plane passing centrally, lengthwise through the branding or marking head.

Figure 5 is a view in section on a plane denoted by the dotted line 5 of Figure 4.

Figure 6 is a side view of the branding or marking head.

Figure 7 is a` view in cross section through the marking or branding head and supporting table on a plane passing through the marking or branding dies, parts of the machine underneath said table being broken away.

My improved machine shown and describ` ed herein may be, as a whole, supported in any desired manner, the machine illustrated embodying a base plate 10 that may rest upon any suitable support. A bearing bracket 11 is secured to and rises from this base plate and is 'provided at its upper end with bearings 12-13-for a driving shaft 14 that may be rotated in any suitable' manner, as by a belt passing about a driving pulley 15 secured to said driving shaft. A flanged collar 16 is secured to the endfof the driving shaft opposite said pulley, and a marking or branding head 17 is secured to the flange of said collar as by screw bolts 18 passing through spacers 19 by means of which the marking or branding head is spaced from said collar, the bearings 12 and 13 being of sufficient length -to rigidly support the marking or branding head and parts secured thereto, e p

The marking head 17 is provided with markers 20 located on the periphery of the marking head. rIhese markers may be formed in any desired manner, intergral with or separate from said' head. In the preferred form of construction and as shown herein these markers or branding members are in the form of dies comprising marker bases 21 secured in grooves v22 in the marking head, sai-d grooves being preferably of dovetailed shape to receive said bases of the same shape, and preferably said grooves taper from a certain width at one end to a different width at the other end so that the markers will be tightly wedged as they are driven endwise into said grooves.

The marking head is provided in its interior V,with any suitable means for heating said head and said markers or branding members to a proper degree for marking purposes.` In the structure herein shown this heating'member 23 comprises a coil constructed in any ordinary and well known manner to receive a current of electricity to cause said coil to be heated and suchheat to be transferred from the coil to the head 17. The structure of this coil is not specifically shown herein as it will be readily understood by those skilled in the art. The opposite ends of the structure comprising said coilare extended out at the end of the head 17 forming terminals 24--25 to which conf ductors 26-27 are connected. l

A case 28 'rs attached to the end of the head 17, and a neck 29 projects from said case, a cap 30 closing the opening at the outer end of the neck. A bolt 31 extends through said cap, neck, and case, and through the head 17, the end of the bolt being threaded into the shaft 14, as shown in Figure 4 of the drawings, and any suitable means, as a head 0r a nut, may be employedv to secure the bolt against the c'a 30. An opening 32 within which said bolt projects in the head 17 is preferably larger than said bolt kto provide a space entirely therearound.

An insulator 33 fills the chamber within the case 28 and the neck 29, such insulator being for the purpose of preventing transfer of heat from the head 17 to the case 28 and parts of the mechanism thereon, and such linsulator may be composed of any suitable non-heat conducting n'xaterial,l as asbestos.

tor and the conductors 26-27 extend throu h it and through openings in the side of t e neck 29 to the outer side thereof. Dowel pins 34 extend into the facing edges of the head'17 and case 28, and spacers 35 are employed to separate the case from the head. Said spacers may be formed as an integral part of the dowel pins if desired.

The conductor 26 is secured to a conducting collar 36 mounted on an insulating sleeve 37 attached to the neck 29 in any suitable manner, and the conductor 27 is secured to a similar conducting collar 38 mounted on said sleeve.

A standard 39 is supported by the base .10 and rises therefrom and has a brush supporting plate 40 secured to its upper end and projecting beyond the side thereof, brush supports 41-42 extending through openings in the projecting part of said plate. Wires 43-44 are secured to the supports 42-41 and brushes 45-46 are yieldingly mounted in any suitable manner in the supports 41-4 2,' said brushes bein thus held in .yielding Contact with the sai collars 364-38, By this means a current of electricity is set up from an?7 suitable source (not shown herein) througi the members and conductors above described lto the heating member 23 and therefrom back to said source in a manner that will be readil understood.

A bloc 47 is secured to the base 10 and a table supporting bracket 48 is secured to and projects from said block. A table 49 is-pivotally attached to said bracket, said table preferably having a groove 50 within which articles 51', as wooden handles, are located and along which they roll, the table 49 bein inclined to cause such rolling action. The ta le is yieldingly supported upon a plunger 52 seated upon a spring 53 in a recess 54 in the block 47, as shown in Figure 7 of the drawings.

Positioningplungers 55 project from the upper surface of the table to intercept the artlcles 51 and stoptheir rolling movement in proper sition to .receive the markers. 20, as the atter are rotated with the head 17 above such articles, but in position to come in contact therewith. These positioning members are ieldingly mounted upon springs 56 locatedy in spring cases 57 'pro- )acting from the under surface of the table' 49, the positioning members ro'ectin u vwardly through the table, and als shovn iii Fi re 7 of the drawin he `peration of thi machine will be readily understood, it being noted that the head 17 is so insulated that the heat therefrom will not be communicated to an objectionable degree to other portions of the machine. The positioning members 55 intercept the articles to be marked in such position that the markers 20, as they sweep over the articles, will come in contact with member, said member being them and roll them along, the positioning members 55 in this operation being depressed suiiiciently to permit the articles to roll over them, and the spring pressed plunger 52 also yielding to -enable the table to move downwardly and thus perimt the articles to pass underneath the markers, this plunger maintaining sul'licient pressure between the articles and the markers to cause the latter to effectively mark or brand said article.

The collars 36 and 38 are secured as by set screws, as shown in Figure 4 of the drawings, and inorder to elfcctively secure them in place a shoe 58 is interposed between each collar and the sleeve 37 lagainst which shoes the set screws bind to hold the collars securely in place.

While the case 28 and neck 29 vprojecting therefrom are shown as filled with an i11- sulating material, it is observed that it is not absolutely essential to the invention that said case and neck shall be thus illed, as extremely satisfactory results will be -obtained without any lling whatever in said case and neck. l y

In accordance with the provisions of the atent statutes IA have described the principles of operation of my invention, together with the devicevwhich I now consider to represent the best embodiment thereof; but I desire to have it understood that the device shown is only illustrative,land that theinvention may be carried out by other means.
