PRINTING MECHANISM,

Application filedlseptemb'er 15, 1924.. Serial no. 737, 40.

To all whom it may concern:

Be it known that I, PAUL P. COMMANDER, a citizen of the United States, residing at Doerun, in the county of Colqui-tt and State of Georgia, have invent-ed a new and useful Printing Mechanism, of which the following is a specification.

The device forming the subject matter of this application is a printing mechanism adapted to be used primarily for printing on boxesof fruit, the number of pieces of fruit in the box, the packers number, or any other data which it may be desired to impress on the box. The invention aims to provide a printing member so constructed that the type-carrying portion thereof may be swung upwardly against the box, to PI'OVlClG novel means for operatmg the printing member, to provide novel .means for inking the type on the printing member, and, generally, to improve and to enhance the utility 'of devices of that sortto which the invention appertains.

Although a preferred form has been shown in the drawings, it will be understood that a mechanic, working within the scope of what is claimed, may make changes and alterations, withoutdeparting from the spirit of the invention.

In the accompanying drawings Figure 1 shows in top plan, a device constructed in accordance with the invention, a portion of the bench or support being broken away; Figure 2 is a side elevation; Figure 3 is a perspective disclosingone of the type bars and attendant parts; Figure 4: is a section on the line 1-4 of Figure 2, parts being broken away; Figure 5 is a sectional elevation wherein thetype bar has been brought up against the box which is to be imprinted; and Figure 6 is a section on the line 6-6 of Figure 1. i

The printing mechanism forming the subject matter of this application contemplates the provision of a support 1, which may bea packing bench of the sort disclosed in my co-pending application Serial Number 7 37 839, filed on the 15th day of September, 1924. The support or packing bench is not described in detail, because I know that one cannot claim the details of a packing bench, and thedetails of a printing mechanism in the same application. The support 1 embodies legs 3 merging into horizontal memhere 4 carrying any suitable means 5 for supporting a box 2 of the kind in which of the bench frame. plungers 10 are adapted to abut against the the cross piece 7 and the supports 4, the

brace being omitted in Figure 1, and else where, to the end that the printing mechanism may notbe obscured by mere bench details. There are guides .9. cross piece 7, the the form of eyes.

Passing from bench construction to printing mechanism, it will be noted that operating members 10, in the form of plungers, are loosely mounted for vertical reciprocationin the guides 9, the plunge-rs being provided at their lower extremities with pedals 11 which extend beneath the bench, at each side thereof, so that an operator on eitherside of the bench may actuate the printing means. The upper ends of the plungers 10 are inwardly offset, as shown at 12, and terminate in eyes 14 located between

nuts

15 and 16 on a pivot rod 17 having abutments 18 located inwardly of the nuts 16.

The inner ends of levers 19 are mounted pivotally on the rod 17, between the abutguides preferably being in ments 18 and the nuts 16, the levers being fulcrumed intermediate their ends on a rod 20 connected at its ends by securingelements 21 with the legs 8. Tubular spacers 22 are mounted on the fulcrum rod 20 between the inner edges of the legs 3 and the. levers 19, and, cooperating with the abutments 18 on the pivot rod 17, hold the levers19 for parallel swinging movement in vertical planes. The outerv ends of the levers 19 are upwardly curved, as shown at '23, and are connected by securing members 25 to a carrier block 24. The parts 1923-24: may be alluded to generally and briefly as a U- shaped lever fulcrumed intermediate its. ends on the support 1. In order to swing'the ends 23 of the levers 19 downwardly from the printing position of Figure 5 to the inking position at Figure 2, a retractile spring26 is connected at its ends to the carried block 24:and to the lower cross piece 7 The angles 46 of the sleeves or spacers 22 to stop the levels 19 in the inking position of Figures 2 and 6.

The carrier block 2% is provided with any extending between on the 7 lower desired number of openings 27, spaced apart it longitudinally of the block and communicating with enlarged seats 28'formed in the upper surface of the block. The openings 27 of the carrier block 24: receive slidably,

the stems 29 of the type bars 30 carrying brought up against the end of the box 2,

as shown in Figure 5, but if enough pressure is exerted on the pedals 11, the shoulders 53 on the stems of the type bars may come into contact with the carrier block at at the bases of the seats 28, thus forcing the type 31 against the end of the box 2 positively. The enlargements 32 in the stems of the type bars not only form the shoulders 53, but, as well, conform closely but somewhat loosely tothe springs 33, so that the springs will not tend to flex too much sidewise, when they are under compression. The upward movement of the type bars 30, responsive to the springs 33, is limited by step pins 3%, which, being inserted through the lower ends of the stems 29, engage the lower surface of the carrier block 24. In order to prevent the stems 29 of type bars 30 from rotating in the carrier block 24:, and in order to position the type 31 properly with respect to the end. of the box 2, the type bars slide in contact with an upstanding guide plate 35 secured at 36 to the carrier block 24:.

Referring to the inking mechanism, it is :to be observed that a substantially hori- Zontal'U-shaped frame 37 is held on the legs 3 of the bench frame by the-securing elements 21 which engage the ends of the fulcrum rod 20. Although any suitable means may be provided for inking the type 31, it is contemplated that recourse may be had to a known construction, including a pad 38 carried by the body 39 of a box, a lid 10 being hinged at 4.1 to the body,the pad resting on the type 31, and the lid L0 extending downwardly within the rear portion of the frame 37 securing devices 42, connectingthe lid to the frame 37. One of the securing devices 42 retains an upstanding spring tongue 13, overhanging the body 39 of the pad carrier, and adapted to be put under tension by contact with the part 39, when the pad 38 is swung upwardly from the position of Figure 6 to the position of Figure 5, the element 43 being in substance a return spring for carrying the pad back into the position of Figure 6 on the type '31, or, at least, being a means whereby the pad 38 is prevented from being swung over too far to the-right in Figure 5. The means for moving the pad 38 from the type-engaging position of Figure 6 to the position of Figure 5 embodies a curved arm or opener, held on the carrierblock 24 by one of the elements 25 which attach the carrier block to the levers 19. The arm or opener 4a is adapted to work beneath an outstanding lip 45 on the body 39 of the pad carrier, and this lip may be made conveniently by simply bending outwardly, one of the side walls of the box body 39 which holds the pad 38.

Assuming that the box 2 is in the position delineated in Figure 5, the operator presses downwardly on one of the pedals 11, the plungers 10 moving downwardlyin the eyes 9, the levers 19 being tilted on their fulcrum 20. Thecurved opener 14, moving with the levers 19, rides beneath the lip 15 on the pad carrier 39 and swings the pad 38 out of the path of the type 31, the part 39 engaging the spring tongue 43 and putting the same under tension. The levers 19 carry the block into the position of Figure 5, and the box 2 is printed upon at one or more places, de-- pending upon the number of type bars 30 that are used. 7 When pressure on the pedal 11 is released, the spring 26 swings the levers 19 and carries the type bars 30 and the carrier block 29 away from the box 2, the opener a4, retiring from beneath the lip as of the pad body 39, the pad assuming the position of Figure 6, under the action of the spring tongue 4E3.

Not only may the number of articles in the box 2 be printed thereon, but, also, the box may be marked with the packers number and other indicia tending to prevent fraud, these details relating more to packing house management than to the operation of a printing device of any specified form.

What is claimed is 1. In a device of the class described, a support, a type lever fulcrumed on the support, type on the type lever, a swinging pad cooperating with the type, and an opener coacting with the pad to swing the pad away from the type when the lever is swung in one direction, the opener being carried by the lever, the opener having arcuate movement with respect to the fulcrum of the lever.
