' MARKING MACHINE.
Specification of Letters Patent.
Patented Aug. 8,
Application filed January 22, 1921. Serial No. 439,257.
' a citizen of the United States, and resident of Keene, county of Cheshire, State of New Hampshire, have invented an Improvement in Marking Machines, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.
This mvention relates to marking machine and has for its object to provide a simple marking machine which can be operated by foot power and which is constructed so that the retracting movement of the printing head from the work support or platen carries the head entirely away from the work thus allowing free space for the operator to manipulate the work.
In order to give an understanding of my invention, I have illustrated in the drawings a selected embodiment thereof which will now be described after which the novel features will be pointed out in the appended claims.
Fig. 1 is a side view of a marking machine embodying my invention.
Fig. 2 is a front plan view.
The marking machine comprises a bed member 1 carrying the platen or work support 2 on which the work to be marked is supported. 3 indicates a printing head carrying type and which is constructed to move toward and from the platen. The printing head is pivotally sustained on the ends of two arms 4 and 5 which are in turn rigid with shafts 6 and 7 that are journalled in bearings carried by the upright portion 8 of the frame. The shafts 6 and 7 are spaced apart a distance equal to the pivotal connections 9 and 10 between the arms and the rinting head. so that the arms have a parallel relation. The bed 1 carries an inking pad 11 situated back of the upright 8 and the manner of mounting the printing head is such that it can be swung from the printing position shown in Fig. 1 over into a position beyond the dotted line position in -Fig. 1 in which latter position the type are in engagement with the inking pad 11. When the printing head is in this retracted position it is entirely removed from the platen and the space above the platen is per e y ee so that t e p r t r c n manipulate the work to be printed without restriction.
My "present. invention provides novel means by which this printing head can be moved from the full to the dotted line position and back again by a treadle, so that the operator has his hands at all time free for manipulating the work.
To accomplish this I have placed a gear or pinion 12 on each shaft 6 and 7, each pinion being made fast to its shaft and I have provided a rack 13 which is guided in the upright 8 and which meshes with both pinions 12. This rack has a rod 14 connected thereto which extends through a guide 15 formed on the bed plate 1 and which is connected to one edge of a foot treadle 16 that is centrally pivoted at 17 to a standard 18 secured to the floor 19. When the end 20 of the treadle is depressed the gears 12 will be turned in a direction to swing the arms from the full to the dotted line position, Fig. 1 and when the opposite end 21 of the treadle is depressed, the arms will be swung back into the full line position again. The treadle is so arranged that the operator will place his entire foot thereon and consequently a downward movement of the operators toe will swing the printing head back into its inking position, and a downward movement of the operators heel will swing the treadle into printing position shown in'full lines, Fig. 1.
The shaft 6 is shown as having an arm 22 fast thereon to which is connected a pulling spring 23, said spring being of sufficient strength to balance the weight of the printing head so that when the treadle is released the spring will raise the printing head somewhat. In actual operation the operator will actuate the treadle to bring the printing head into the printing position shown in full lines, Fig. 1, in which position it makes the printed impression on the work to and then will depress the toe operation of the treadle to swing the printing head over into contact with the inking pad 11, thus to ink the type. If,
at this time, the treadle is released the tion of the treadle to cause another printed impression to be made and will then depress the toe portion of the treadle to ink the type, after which the treadle will be released, thusallowing the spring to raise a the head slightly from the inking pad. The
shafts 6 and 7 are j ournalled and the pinions 12 and rack 13 are located between the arms of the fork. This forked construction provides a suitable guide for the rack.
I claim.
1. In a marking machine, the combination with a bed having a work support and an inking pad located in parallel planes, of a vertical support rising from the bed between the work support and pad, two shafts journalled in said support, an arm rigid with each shaft, said arms having a parallel relation, a printing head pivotally connected to the ends of the arms, a gear on each shaft, a rack meshing with said gears, a
treadle connected with said rack, movement of the rack turning the shafts thereby to carry the printing head from the work support on one side of the vertical support to the pad on the other side of the vertical support, and a spring acting on one shaft and normally holding the printing head slightly elevated from either extreme position.
2. In a marking machine, the combination with a bed having a work support and/ an inking pad, of a vertical support rising from the bed between the work support and pad, two shafts journalled in said support, an arm rigid with each shaft, said arms having a parallel relation, a printin head pivotally connected to the ends 0 the arms, a gear on each shaft, a rack meshing with said gears, a treadle connected to the rack, movement of the rack turning the shafts sufiiciently to carry the printing head from the work support to the inking pad, one of said shafts having a second arm rigid therewith, and a spring connected to said second arm and operating normally to hold the printing head in a position between its two extreme ositions.
In testlmony whereof, I have signed my name to this. specification.
