MART ENG MAUI? This invention relates to marking machines of the type which comprise a wor St aport and a printing head carrying type c ire were and movable toward and from the work support to make the printed impresslon on the work.
The object of the invention is to provide a novel means for supporting and movement to the printing head and the novel features thereof will be more fully herein after set forth and then pointed out in the appended claims.
lnthe. drawings, Fig. 1 is a side view of a marking machine embodying the invention and showing the type in inking position;
Fig. 2 is a similar view showing the print ing head in position to make a printed impression.
1 indicates the frame of a marking machine embodying my invention, and 2 indicates the work support on which the work or sheet 3 to be printedis placed. The print ing is done by type members 4 that are carried by a printing head 5, the latter being movable toward and from the work sup port 2. The present invention relates to novel means for giving the printing head 5 its movement.
This printing head is shown as carried by the lower end of an arm 6, the upper endoit which is pivotally connected at 7 to one end of a lever 8. the latter being pivoted at 9 to the frame 1. The lever 8 extends beyond the pivot point 9 and the extended end has a pulling spring 10 connected thereto which tends to raise the front end of the lever to which the printing head is secured.
The movement of the printing head toward and from the work support is controlled by a toggle lever device comprising the two toggle elements 11 and 12 which are pivoted together at 13. he toggle element 11 is pivoted 14 to the frame 1 and. the toggle element 12 is pivoted at 15 to the arm 6.
16 indicates a pulling spring which is connected at one end to the pivotal connection 13 of the toggle lever device and at theother end is connected to the frame preferably to the pivotal connection 9. The spring 16 thus has a normal tendency to break the toggle 11, 12 and to swing it into the; position shown in Fig. 1. VVhe-n the toggle Divided and this application filed February to,
Serial No. 89,2412.
head will be brought back into printing on, as shown in Fi 9 The straight 0 .u-l-I airing of the toggle is acc'dmplished manually by means of a treadle not shown, which is connected to the toggle element 11 by means of a link or connection 17.
The temple device is provided with a stop constructed so that it cannot be bent or broken below its straightened position. This stop is in the term of an abutment 18 car *ied by the toggle member 12 and an adjustable screw 19 screw-threaded in a boss 20 carried by the toggle member 11. The screw 19 will be adjusted so that i will enthe abutment when the toggle elements have been swung into their straightened position.
In the operation of the device and assuming that the printing head is in its retracted position shown in Fig. 1 a downward pull on the connection 17 will first straighten the toggle thereby swinging the lower end of the arm 6 forwardly and carrying the printing head 5 forwardly into a position over the work support. Continued downward pull on the connection 17 will then swing the straightened toggle and the lever 8 down-- wardly thus bringing the type characters the work as shown in Fig 2.
lVhen-the toggle lever straightened the distance between the pivots 14: and 15 is the same as the distance between the pivots 9 and? and, therefore, after the toggle lever has been straightened said straightehed toe" gle and lever 8 operate with a parallel ruler motion. The pivot 9 is vertically over the pivot 1-11 and when the straightened toggle land the lever 8 are swung downwardly the printing head will. therefore. be etiven a vertical movement whi h is at ri 1111 entries to the surface of the work support and the type, theretcre will be brousli squarely 'n'st the work. During this downward. 131161 ruler motion the spring 10 is extendllli port is first in a forward direction to bring the printing head directly over the work support and then in a downward direction to bring the type squarely against the work. Similarly, during the retracting movement the printing head will first be moved directly away from the work in a vertical direc tion and will then be swung backwardly.
An advantage resulting from this construction is that the final movement of the printing head which brings the type against thework and also the initial withdrawing movement is in a direction at rightangles to the work support, which is essential in making a clear printed impression.
21 is an adjustable stop against which the toggle member 11 rests when the parts are in their normal raised position.
The type are inked by an inking pad 22 which is constructed to be brought against the type when the printing head is in its normal raised position. This inking pad is secured to a swinging arm 23 which is pivoted at 2% to an arm 25 extending from the frame. The swinging member 23 is connected to the printing head 5 by means of a link 26, the latter being pivoted to the arm at 2? and to the printing head at 28.
The construction and proportion of the parts 23, 26 is such that when the printing head is swung from its operative position shown in Fig. 2 to its raised position shown in' Fig. 1 the member 23 carrying the ink ing pad will be raised thus bringing the inking pad against the type as shown in Fig. 1. When the printing head is moved into its operative position, as shown in Fig. 2, the member 23 is swung downwardly thus separating the pad from the type and this separating movement occurs as the printing head begins to move forwardly so that the type will not have a dragging movement across the face of the inking pad. Similarly, when the printing head returns to the position shown in Fig. 1 the inking pad will be given an upward movement during the last part of the movement of the printing head thus bringing the inking pad squarely against the type.
It will be seen from the above that I have provided a simple mechanism for operating the printing head by which said head is not only brought against the work support and raised therefrom in a direction at right angles to the work support, but is also given a backward movement so as to carry it back of the work support. The advantage of this is that when the printing head is raised it is back of the work support and so that the operator may freely remove the printing sheet from the work support and place a new sheet thereon.
The mechanism has the further advantage that it is extremely simple in construction.
This application is a division of application Serial No. 723,97 filed July 3rd, 192% I claim:
