JOHN J. DAVIES, OF JOHNSTOWN, PENNSYLVANIA.

SPECIFICATION forming part of Letters Patent No. 793,993, dated July 4, 1905.

Application filed November 14, 1904. Serial No. 232,726.

To all Lu-71 0711. lib m/tg concern:

Be it known that I, J OHN J. DAVIES, a citizen of the United States, residing in the city OfJOllllStOWl'l, in the county of Cambria and State of Pennsylvania, have invented certain new and useful Improvements-in Spacing- Indicators for Punching-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which. it appertains to make and use the $211116).

My invention consists of an apparatus, to be automatically operated by a punching-machine, which will accurately indicate to the operator the number of the punch to be used, alsothe number of spaces and the distances center to center of the holes to be punched,

all in a convenient and simple manner, there by facilitating the work.

Certain of the objects of my invention are to furnish the operator with all the information needed without any need on his part of referring to detailv drawings and to expose the said information to his View at the exact time required and in such amount only as is needed for one complete operation of the punching-machine.

A further object of my invention is to red uce to a minimum the liability of errors and the number of men necessary for the successful operation of a multiple punch.

In general my invention consists of an indicating-ribbon, hereinafter more fully described, on which is written or printed in a simple manner the data necessary for the operators use, said ribbon being wound around and connected to two drums, one end to each drum, said drums being secured to and supported on shafts, all so placed and operated that the ribbon automatically unwinds from one drum while it is being wound around the other, the latter of said drums bcin ma do to revolve by power transmitted from a suitable rotating shaft or from the reciprocating head of the punchingmachine by means of a system of levers and shafts operating a pawl which engages a ratchet-wheel secured to the shaft of the latter drum.

The aforesaid drums and ribbon are ar ranged in a case or frame, in which an adjustable shutter is so set as to hide from the operators view that part of the data on the ribbon which is not needed for use at the time and expose that part of it which he requires for the operation of the machine, said shutter being provided with an aperture or slot for this purpose.

Having thus given a general description of certain features of my invention, I will now in order to make the same more clear refer to the four sheets of drawings which form part of this specification, and in which like numbers refer to like parts.

Figure 1 is a front elevation of a multiple pnnching-imichinc fitted with my spacingindicator, said punch being shown in considerable detail, so that the application of my invention may be clearly understood, although the punching-machine itself forms no part of my invention. Fig. 2 is an enlarged front elevation of my spacing-indicator, showing the shaft which transmits the actuating power from the reciprocating crosshead of the punching-machinc to the operating-levers of my indicator and also other details of my apparatus. Fig. is a side elevation of my apparatus, which clearly shows the lever arms, to one of which is connected a pawl, which engages a ratchet-wheel coniwcted to the shaft of the upper drum. Fig. Ll a vertical section of my apparatus, taken on the line Y Y of Fig. 2 and shows the attachment of the indicator-ribbon to the drums, also the rack and pinionoperating the adjustable shutter by means of the milled knob shown in Fig. 2. Fig. is a front view of a portion of a typical indicator-ribbon, forming part of my invention. Fig. (3 is a side elevation of a portion of my apparatus, showing a bracket secured. to the reciprocating crosshcad of the punching-machine, said bracket carrying an adjustable bolt which engages once during every complete movement of the cross-head a tappet-arm shown connected to one end of the transmission-shaft. Fig. 7 is an end elevation of one of the drum shaft bearings, Fig. 8 is a cross-section taken on the line X. X of Fig. 7. Fig. 9 shows an alternative method of connecting my apparatus to a punehing-inachine. Referring now to the various characters of reference on the drawings, 1 is the mam frame of a multiple punclung-machine having a reciprocating cross-head 2, to which is attached a bracket 3, carrying an adjustable bolt 1, mounted on its projecting leg. Said adjustable bolts: engages a tappet-arm 5, attached to the rock-shaft (5, once during each operative stroke of the cross-head 2, as shown in Fig. 3.

7 and S are bearings attached to the frame and support the shaft (3, which is held in position longitudinally by the collars t).

10 represents a lever, one end of which is attached to the rock-shaft 6, while the other end is attached to the upper end of the lever 11, the lower end of lever 11 being connected to the shaft 13, which carries the ratchetwheel 14 and the drum 12, as shown in Fig. 3.

15 is a pawl connected to lever 11 and engages the teeth on ratchet-wheel 14 at each operative stroke of the cross-head 2.

10 represents the case or frame connected to frame 1 of the punching machine by brackets 22 and 23 and contains the drums 12 and 17, and it also carries their supporting-shafts, &c., as shown in Fig. 2.

18 represents the ribbon, which is spaced oil into sections, as represented by 19 and 20 of Fig. 5. The number and spacing to be used by the operator is printed on the left of the dividing-line in sections 19, while the number of the punch or punches to be used is printed on the right of the dividing-line in sections 20. 7 I

21 is a solid circle shown in Fig. and indicates plainly to the operator the last hole which is to be punched of any series.

21 represents the adjustable shutter, which has an ranged, grooves 26.

27 is a milled knob, (shown in Fig. 2,) which is attached to shaft 28, carrying the pinions 29, which engage the teeth on the racks 30, fastened on the inside of the shutter 24-, all as shown in Fig. 4.

31 represents hooks, by means of which the ribbon 18 is secured to the drums 12 and 17.

32 is a shaft carrying the drum 17 and having a crank 33 attached to one end for rewinding ribbon 18 on the drum 17, as shown in Figs. 2 and 3. I

34: represents felt washers placed on the shafts at each end of the drums 12 and 17, as shown in Figs. 2 and 8, to prevent said drums from moving too freely. V

35 represents a locking-plate which forms part of a split bearing and is held in posiaperture 2:) on its face and so aras to slide up and down in the tion b i the sirin 36. as shown in Fi s. 7

' b I I) up and in turn .by transmission through the shaft 6 throws the lever 10 upward, carrying with it lever 11, which is attached to shaft. 13 of the drum l2. The pawl 15, attached to lever 11, then enga the ratchetwheel. 14:, thereby causing said ratcl'iet-wheel to revolve through a certain portion of an are equal in distance to the width of one of the spaces 19 20 on the ribbon 18 and expose j the figures inscribed on said ribbon through th v aperture 25 in the ad ustable shutter 21. The operator upon reading the figures exposed throws the spariiig-lever of the punch into position such that the traveling :arriage .of the punching-machine moves the proper distance for the next space between holes, and he also sets from the same reading the punches which are needed in the next operative movement of the punching-machine. lVhere there are a number of equal spaces in succession, my apparatus will. indicate the spaces accurately and show the operator when to make a change in the spacing or the punches.

The :nljustable shutter 25 is fitted on its rear side with two racks 30, which engage the pinions 2t), that are connected to the shaft 28, which has a milled knob 27 at one end. iy turning this knob the shutter an be adusted so as to allow for any inaccuracy in i the initial placing of the ribbon 18 or for the inaccuracy consequent upon the accelerated l'l'lOVOlilOllt of the ribbon due to the iiicreascd diameter of the roll as the ribbon is wound upon it.

The crank 33, secured to the end of shaft is used to rewind the ribbon 18 on the drum 1? when said ribbon is to be used over again. B y a system of split bearings (shown in Figs. 7 and S) the drum 17 may be readily changed when, a new ribbon due to a change in the charaeer of work becomes necessary.

Although I have shown and described my invention in considerable detail, I do not limit myself to the exact and definite particulars of the construction, arrangement, or

actuating mechanism shown or llescribed.

Furthermore, although I have shown my iiiveiition. in connection with a. multiple punch,

I reserve the right to apply my invention to any style of a punching-machine. I also wish to reserve the right to use any substitutions, moi'lifications, or equivalents thereof such as are embraced within the scope of my invention and as pointed. out in the claims.
