T @Zlwwmitmez/.Qmmf i Be it knownfthat I, JOHN R. HAGUE, of

` Pittsburg, in the @nary` or Allegheny and turned so` as to present 15` pleak.

State f `Pe.111lisfylvania`,thave invented a new and useful Machine for, PunchingfRivete HoleSin Hosegfandl do hereby declare the following te be'` a full, clear, and exact description` thereof, reference being had to the annexed` drawings, forming `part` rof thisI specification, in which- Figureflis a perspective view of my inachine, and ig. 2`isal pespectiifeview ofthe same withi the sliding table` removed and` A the end and side of the machinewhich are not` shown in" Fig. l. The "several Mparts "of the machine are marked on the drawings with letters of referin the' several figures( In the manufacture of hoser it is very im- POILIlt that the rivets should be inserted at uniform distances apart,"and thatthe holes onfeachside of the belt or strip lofleather of lwhich thehose s to be made sliyoulld exel actly'corres'pond. Sno essential is great ex'- actness in thisrespect that theoperation of punching these holes has been heretofore, so

far as I can learn, always donefby hand,y the" position ofeach punbh hole being h rstcare'-` fully marked, begorel it s cut `by the punch. My machine is designed to perform this work not only much faster than itjcan be done by hand, but with thel'utmest precision, so that when the two Vedges of the leather are brought together for the purpose of inserting the rivet, the rivet holes will so exactly correspond that there shall be no pucker in the leather, which would prevent the joint being close and cause the hose to To enable others skilled in the art to make and use my machine, I will proceed to describe its construction and operation.

A strong framework a, a, consisting of two sides pieces, two end pieces and suitable braces,` is supported on legs, at a convenient height. On the top ofthis frame is a sliding table b, which is designed to receive the belt of leather of which the hose is to be made which is previously cut to the required width according to the diameter of the hose to be made. The leather is laid over the table, and the pressing board c, is laid over it, to keep it even and firmly in its place; the leather projecting equally beyond either side of the pressing board. The pressing board ingitaaisany tamara etree, similar letters being used for likepartsl the tweelingen@ w01" y dewnfTheY workingshaft (tofwhich f will and communicat'es",y accelerated mbtion" to `it. At `ith r `endf`of t-heshaft' r, is any eccentric isusecured at either endby clamps d, QZ, attached to` each end of the sliding table,

laiidfa brace e, extends from' within a short distance of either extremity lof the pressing beard, to prevent its` springingup inthe center," andpreserve a uniform pressure on the leather n the table. "A strip of raek wiork, f, is attached to the underside of the sliding board extending longitudinally from one e'nd to the otherand midway from either side. Thisy gears intoy a colgwheell g, which isH turned handv by means of a winchfb, turning` which the table may be moved and forward' over the frame between the guidesv z', z', &c., attached` to` the sides of the)` frame. At er vnear the center of the `frame a, a, are "two standaards 7c', afone on 'each side f, the

frame, connected.` at the top by the crosspievce Z, whrchserves as a guide` for the punchinggate mf Two blocks or ways 1t, n,

areat'tached, to each standard lfor the slides *of thepunchingjgate"to'woik in, and

which also serve asv Guides` between which motipn is communicvrated` from an engine or oth r motive portier)` carries a cogw'heel p, ch gears into` a pinion g, 0`n the shaft 1,

are connected at top, one to either side of the punching gate m, so that in each revolution of the shaft 1^, the cams s, s, lower the punching gate and raise it again with a perpendicular reciprocating motion. The Hy wheel b, is attached to one extremity ofthe shaft r, and serves to regulate and steady the motion of the machine. The punching gate m, is furnished with two upright steel punches c, c, placed at the requisite distance apart, whichV in each downward stroke of the punching gate pass, one on either side of the pressing board 0, and punch a hole in the leather near to its outer edge on each side. The punching gate may, if desired, be furnished with two sets of punches one set rather nearer the center of the gate than the other set, and placed not in the same line but rather before or behind them, so as to cut a double row of rivet holes, the inner row being so spaced that each hole will come between two holes in the outer row. The punchings of the leather pass up through the punches into the box or trough u, in the gate, designed to receive them. So soonas one pair of holes is punched it is necessary to move the sliding table, which carries the leather forward as far as the required space between the rivet holes. This is effected by the following contrivancezvA narrow strip of rack work fv, isattached to the sliding table near to one side, which extends longitudinally in a straight line from one extremity of the table to the other; the space between the teeth of the rack work is equal to the distance from center to center of the rivet holes. A finger w, which works in the rack u, is connected by a pivot joint to the extremity of the short arm of a bent lever a', the fulcrum y, at the elbow of the lever is attached to the side of one of the standards 7c. The extremity of the long arm of the lever is connected by a rod a, (with a pivot joint at each end), to the punching gate m. Now it is manifest that each time that the punching gate m, is raised by the connecting cam rods t, t, the long arm of the lever x, is raised by the rod 2, which pressing on its fulcrum y, pushes forward j j explained its construction and operation, what I claim as my invention and desire to the finger fw, the point of which is resting against one of the teeth of the rack o, andl moves the sliding table forward, the comparative length of the arms of the lever m being so adjusted to the length of the stroke of the punching gate m, thatthe distance which the sliding table b, moves forward r shall be exactly equal to the length of one tooth of the rack fu. On the descent of the punching gate m, the finger zo, is drawn back until it falls between the teeth next behind that against which it previously rested, without moving the sliding table from its position, and it is not until the holes have f been cut by the punches and the punching gate m rises again, that the sliding vtable b is again moved forward. When the sliding table has passed from one extremity to the other under the punching gate, it will be necessary to release the finger w from the rack o and run the sliding table back to its original position in order to repeat the operation on another slip of leather. To e ect this, an arm d', carried by a rod f, which turns on its axis, is connected by the rod e, with the extremity of finger w. The hand lever g', also attached to the rod f, when drawn back turns the rod f', and raises the arm d', and with it the linger w, releasing it from the rack work. The spring catch Z', holds the hand lever g, in any position it may be placed, in preventing the finger w from catching in the rack o, until it is thrown back for that purpose. The finger w, being raised, the sliding table may be by means of the cog wheel g, and rack f, accomplishes that purpose. The hand lever g', is then thrown back, the finger w, catches in the teeth yof the rack o, and the operation of the machine is repeated.

Having thus described my machine and secure by Letters Patent, is-

The use of the sliding table and the pressing board in combination with the rack work the lever and the finger, .for the purpose of moving forward the leather on the sliding table during each stroke of the punching gate and in combination with the 'punching gate and punches substantially in the manner and for the purposes hereinbe- JOHN R. HAGUE.
