PAPER-FEED FOR PERFORATING-MACHINES- Specification of Letters Patent.

Patented Dec. 4, 1906.

Application filed May 24. 1906. Serial No. 318,521

Be it known that I, PmLiP J ACOB MEAHL, a citizen of the United States, and a resident of Bayonne, county of Hudson, and State of New Jersey, have invented certain new and useful Improvements in Paper-Feeds for Perforating-Machines, of which the following is a specification.

My invention relates to means for feeding forward paper in a perforating-machine.

It is especially adapted to machines for perforating music-sheets, such as are used in pianolas, pianolapianos, and similar mechanical musical instruments or players. For economy of production it is advantageous thata large number of these sheets, say fifteen or more, should be perforated at once and that the machine should be operated at-a high speed, say seven hundred and fifty revolutions per minute. As the sheets of paper are of considerable length, up to ninety feet, it is very important that they shall be fed forward very accurately step by step and that all the sheets shall be fed forward together without any creeping of any of the sheets.

The object of the present invention is to provide means for these results, as well as toprovide means for stopping the machine very promptly at will whenever this becomes necessary.

Further objects of the invention will appear in the specification and be pointed out in the claims' In the drawings, Figure 1 is a side elevation of so much of a paper-feed as is necessary t show my invention. Figs. 2, 3, and 4 are vertical transverse sections .through the planes 2 2, 3 3, and 4 4 of Fig. 1, respectivelyl -1 designates the frame of the machine, which is suitt f supported by means not shower, and consists of two superposed parts 2 and 3. These can be separated from each other to allow for variations in the thickness at paper or the number of sheets. As a means to. this end I have shown dowel-pins 4 4, passing into registering apertures in the frames 2.21m 3, the frames being separated by a strip of metal or the like 5, the thickness of which may be varied as desired. It is obvious that other means for adjusting the distance between the frame parts 2'and 3 may be substituted. Mounted on the upper frame part 1 and passing-transversely thereacross is a shaft 6, carrying a gear-wheel 7 at one end, and sprocket-wheels 8 9, which are spaced apart from each other to a distance s ightly greater than the width of the paper sheets to be fed. In a suitable aperture 10 in the frame part2 is adjustably mounted a pair of journals 11, in which rotates a shaft 12. An adjusting-screw 13 is provided for securing the proper tension of s rocketchains 14, which engage in the test of the sprocket- wheels 8 and 9, mounted on the shaft 6, and in the teeth of sprocket-wheels 15, mounted on the shaft 12. chains consist of the usual links 16, connected by pins 17, on which are mounted rollers 18. Passing between the two sprocket-chains 14 at frequent intervals are cross-bars 19, faced with rubber or similar strips 20. Secured to the frame portions 2 are inwardly-projecting brackets 21 through which freel pass headed pins 22, the lower ends of which are secured at opposite ends to a cross-bar 23, springs 24 being placed on the pins 22 to force the bar 23'downward. At each end of the bar 23 and beneath the same are secured presserbars 25, which bear u on the rollers 18, between the links 16 of tl fe sprocket-chain. Mounted on the lower frame part 3 are parts precisely similar to those described and numbered from 6%025 inclusive, the gearwheel 7 on the lower shaft 6 being in mesh with the gear-wheel 6 of the u per shaft 7. The effect of this is that when the shaft 6 is rotated the sprocket- chains 14 and 14 will be caused to travel with their adjacent faces in the same direction, so that the rubber strips on both the upper and lower sides of cross-bars 19 will be ressed toward each other. Between the rubber faces 20 of the upper and lower sprocket-ohains is passed a plurality of sheets of paper 26. i

a means of feeding forward the sprocket- chains 14 and 14, and thereby feeding the paper sheets 26 in the desired direction, I provide a train of gears consisting of a pinion 27, meshing with the teeth of the gearwheel 7. Mounted on the shaft with this pinion 27 is a Geneva .wheel 28, shown as aving eight teeth which en age .vith a in 29, mounted on a pinion 30, tile pinion eing provided with a crescent-shaped plate 31, bearing a ainst the concave faces of the Geneva w eel 28 to prevent slipping of the same. As shown, the teeth of the mion 30 mesh with teeth mounted on a beve gear 32, which meshes with a corres ending bevelgear 33 ,on a shaft 34, to wfiichcontinuous The sprocketlIO motion is imparted by means not shown, but which may be connected with the perforating portion of the machine, the Geneva wheel .28

and the pinion 27, secured thereto, both being 5 mounted on a hub 35 for sliding motion on a the pin 40 is engaged in the inner an ular;

' groove 37 the Geneva wheel 28 will mesh with the pin 291a11d the pinion 27 will mesh 5 with the gear-wheel 7-, and that when the Y erator slides the wheel 28 outwardly on t e shaft 36, so that the finger 40 engages with the outer annular groove 38, the; Geneva wheel 28, and the pinion 27 will be: d,rawn 2,0 from their respective engagements andthe, movement of the paper-feeding. chain's stopped;

viousfrom the foregoing description- 1t- 2 5 will be seen that the presser-bars 25, runnin I on the rollers 18 of the sprocket-chains, .wil produce very little friction and will act efficiently to hold the rubber faces 20"of the bars 19 closely against the upper and under sides of the paper sheets, the pressure being equal from side to side, and thereby securing the even feed of all the sheets It will also be seen that by'providing the adjustable journals 11 at the same ends of all the sprocket-chains the adjustment of the chains to compensate for wear, is made possible without in any Way interfering with the registrationof the cross-bars-19 on the opposite pairs of chains. It will also be understood 0 that mechanical modifications may be made in the device without departingfrom the in- 'vention.
