FRANK D. MACK, OF CHICAGO, ILLINOIS.

PERFORATOR FOR AUTOMATIC TELEGRAPHING.

SPECIFICATION forming part of Letters Patent No. 439,164, dated October 28, 1890.

Application filed July 13, 1889. Serial No. 317,485. (No model.)

To all whom it may concern: Be it known that I, FRANK D. MACK, resid- 1ng at Chicago, in the county of Cook and State of Illinois, and a citizen of the United States,

have invented a new and useful Improvement in Perforators for Automatic Telegraphing, of which the following is a specification, reference being had to the accompanying drawings, in which Figure 1 is a plan. Fig. 2 is a detail, being a section through the upper part of the machine, taken at line 2 2 of Fig. 1. Fig. 3 is a vertical longitudinal central section. Fig. 4 is a detail, being a front view of the plate which receives the punches or pins and some other parts. Fig. 5 is a detail showing the arrangement of the perforating-pins. Fig. 6 is a side elevation showing two of the perforatingpins and bars to which they are attached. Fig.7 is a detail,being a side elevation of one of the sliding bars which act upon the crossbars, which are secured to the sliding bars which carry pins.

This invention relates to apparatus for perforating paper in automatic telegraphing; and the objects of the invention are to improve the prior mechanism and to provide novel means whereby the single depression of one key will produce the dots, dashes, and spaces required for any one letter.

To accomplish these objects my invention involves the features of construction, the combination or arrangement of devices, and the principles of operation hereinafter described and claimed.

In the drawings, 1 indicates a base; 2, a narrow front piece; 3, a rear piece, which forms part of the frame, and 4 a top piece, the center of which is cut out, which forms the upper part of the frame, and is supported by the rear piece 3 and by two posts, one of which 5 is shown in Fig. 3, the other post being at the right-hand of the machine. Screws 6 pass through the part 4 into the posts 5.

7 are a number of keys or levers, of which, as shown, there are twenty-four. Each lever is provided with afinger-piece 8, each of which is used for a letter, except that the letter J is made by repeating the letter N, and the letter L is made by combining the letters I and M. I have indicated on these keys the arrangement of the letters which I suppose to be the most advantageous. Each keyor lever 7 extends back, as shown, on a diagonal line to the rear of the machine, and is there pivoted on a rod 9, which is supported in the frame, and from there each key or lever extends up vertically, and each vertical part 10 is pivoted at its upper end 11 to a sliding bar 12, which sliding bars 12 are all supported in cross-bars 13 and 14, which are secured to the upper part of the frame. Each of these sliding bars 12 is provided with one or more lugs 15, for the purpose of operating the punch rods or pins, as hereinafter more fully described.

16 are four bars, each one of which carries at its forward end a punch rod or pin 17 18 19 20. These bars 16 are supported by and slide in a cross-bar 21 and a guide 22.

23 are four shorter bars under the forward ends of the bars 16, each of which carries at its forward end a punch rod or pin 24 25 26 27. 28 is another sliding bar at one side of the bars 23, and this bar carries a punch rod or pin 29. All of these bars 23 and 28 are supported by and slide in the cross-bar 21.

3O 31 32 33- 34 are cross-bars, one of which is permanently secured to each one of the sliding bars 23 and 28, and 35 36 37 38 are four other cross-bars, one of which is secured to each one of the sliding bars 16. The ends of these bars 30 to 38 are recessed, and are arranged in slides and guides 39, which are provided with partitions 40.

41 are springs arranged to act upon the ends of the cross-bars 30 to 38 and return them to their normal position after they have been 7 forced forward.

42 is a block through which the pins 17, 24,

.and 29 pass loosely. Each of these pins is provided with a fixed collar 66, arranged to come in contact with the back side of the block 42.

43 is a punch rod or pin, which is permanently secured to the block 42.

44 are springs, which encircle rods which are permanently secured to the plate 47 ,which springs act upon the block 42 and return it to its normal position after it has been moved forward.

45 is a bracket secured to the frame.

46 is a plate secured to the bracket 45,which plate is provided with holes to receive the punch rods or pins.

IOC

47 is a plate secured by screws to the plate 46, washers being placed between the two plates to provide a space for the passage of thepaper to be operated upon.

All of the punch-pins pass through a plate 64, which is supported by the frame, and in their normal position their forward ends enter the plate 47.

48 is a rock-shaft, the ends of which are pivoted in the posts 5.

49 are arms rigidly secured to the rockshaft 48.

50 is a cross-bar suspended from the arms 49 by the rods 51. Each lever 7 is provided with a notch on its under side to receive the cross-bar 50, and the depths of the notches in these levers 7 vary.

52 is a cylinder supported in brackets 53. There are two of these cylinders-one on each side of the center of the machine.

54 are short cylinders provided with heads at each end, which cylinders enter the cylinders 52 a short distance.

55 is a spring located in the cylinder 52, arranged to act upon one of the cylinders 54. There is a similar spring in the other cylinder 52.

56 are arms secured at their lower ends to the rock-shaft 48. Their upper ends are arranged to engage with the outer heads of the cylinders 54.

57 are two feed-wheels, which are provided with sharp teeth, for the purpose of feeding the strip of paper through the machine.

58 are two wheels, each provided with a rubber surface, between which wheels 57 and 58 the paper passes.

59 are pawls pivoted one to the front end of each of the short cylinders 54. These pawls engage with ratchet-wheels on the lower ends of the shafts which carry the wheels 57, which shafts are supported in long bearings 60, which are supported by the bracket 45.

61 is a bar supported by two levers 62, which levers 62 extend back to and are pivoted upon the shaft 9. These arms or levers 62 are also provided with notches to engage with the bar 50.

63 is a spring, one of which is provided for each of the levers 7 and for the bars or levers 62.

The operation is as follows: To indicate a dot at the beginning of a letter requires the pins 43 and 29. To indicate a dash at the beginning of a letter requires the pins 43 and 24. Thus the pin 43 must be used at the beginning of every letter. If the pin 29 be pushed forward, it will carry with it the pin 43, because the collar on 29 will cause the block 42 to move, and the pin 43 is fast to this block, and these two pins being one over the other perforations made by them will indicate a dot. If the pin 24 be moved forward, it will carry the block 42 along, the pin 43 moving with it, and the pins 43 and 24 being diagonal with each other their perforations will indicate a dash. Each of the bars 12 is operated by one of the keys 7, and each bar 12 is to be provided with lugs 15, sufficient in number and properly arranged to operate the pins brought-into use in making the perforations required for the letter to be indicated. For example, F requires a dot, a dash, and a dot, and then there must be a space after the last dotto show that the letter has been completed. Therefore when the F-key is struck, the pins 43 and 29 to indicate a dot, the pins 17 and 25 to indicate a dash, and the pins 19 and 26 to indicate another dot, must all be operated simultaneously, and then the paper must be moved beyond the pins, so as to leave a space after the perforations. To do this the proper bar 12 must be provided with lugs to act on the bars 30, 35, and 32, 37 and 33 at the same time, and then all the perforations required for the letter F will be made, because the bars last mentioned are connected with the sliding bars, which carry the pins to be operated. After these perforations have been made the paper must be moved far enough to carry all thelast-made perforations beyond the pins and provide a space. The paper is moved by the pawls 59 and wheels 57, and the distance the paper moves is determined by the depth of the notch in the lever which is operated. When one of the levers 7 descends, the shaft 48 will be rocked through the rods 51 and arms 49, and the arms 56 will force the cylinders or plungers 54 into the cylinders 52, which will carry the pawls 59 back, the distance which they are moved depend ing on the distance which the lever descends. When the lever is released, the springs in the cylinders 52 will act on the cylinders or plungers 54, forcing them forward with the pawls 59, which, being engaged with the ratchet-wheels 65, will cause the wheels 57 to rotate, carrying the paper along the proper distance. The pointed teeth on the wheels 57 will engage with the rubber on the wheels 58. A double space can be provided for at the end of each word by depressing the bar 61, and the arms or levers 62 will engage with the bar 50, rocking the shaft 48, and causing the plungers 54 to enter the cylinders 52, and when the spacing-bar 61 is released the action of the springs in the cylinders 52 will cause the pawls to operate upon the ratchet-wheels, as before, moving them one notch. I have not provided any keys for the letters .1 and L. To make the perforations for the letter J, the space-bar 61 is to be held down. Then perforations for the letter N are to be made twice. Then the space-bar 61 is to be released, and the paper will be moved the proper distance. To make the letter L, the space-bar 61 is to be held down. The perforations for the letterI are to be first made and followed immediately by the perforations for the letter M. Then by releasing the space-bar 61 the paper will be moved the proper distance. By-the use of the space-bar alone the feed-wheels will be moved one notch. When perforations, are

made which indicate dots, the feed-wheels will be moved two notches When perforations are made which indicate dashes, the feedwheels will be moved three notches.

A full-sized machine may be about ten inches long, about three inches wide at the back, eight inches in front, and about four inches high. The parts are to be made of metal, and must all be made strong and of good workmanship, the best of steel being used for the working parts.

\Vhat I claim as new, and desire to secure by Letters Patent, is as follows:

1. In a perforating-machine for automatic telegraphing, the combination of a series of movable perforating-pins for punching parallel rows of perforations, pin-operating devices, a series of keys for actuating the pinoperating devices, and each of which in its movement advances two or more of the perforating-pins, a rotating wheel having teeth to punch a center line of perforations, and means for rotating the wheel by the movement of the keys, substantially as described.
