MACHINE FOR BEATING LEAF METAL.

SPECIFICATION forming part of Letters Patent No. 661,618. dated November 13, 1900. Application liled August 22,1900. Serial No. 27,645U (No model-J Tolal whom it may conoci/:n:

Be it known that I, FRITZ NUSSER, a subject of the Kingof Bavaria, residing at Frth,

in the Kingdom of Bavaria, German Empire, 5 have invent'edcertain new and useful Improvements' in Machines for Beating Leaf Metal, of which the following is afull, clear, and exact description.

The present invention relates toa machine ro for beating leaf metal, one object being to perform all operations' automatically and in such a manner that the finished Work will be of the sainequality as that obtained by manual labor.

I5 Thed machine consists of mechanism for moving the'work supported on the anvil so that every part of the leal"V metal is brought once beneath the verticallyreciprocating working faceof the hamm-er and the metal zo thus thoroughly and evenly beaten.

Another object of this invention is to release the hammer at the end of its downward stroke, so that it lwill spring back a short dis- .tance after it has been in contact with vthe Work similarly to the blow of a'h'and-hammer.

In the accompanying drawings, Figure l is aside elevation of the machine, showing the mechanism for feeding the work; Fig. 2, a plan or top view of the same; Fig. 3,.an enlarged 3o side elevation of the hammer, partly in section; and Fig. 4, an enlarged vertical section showingthe valve for releasingthe hammer.

a is,a frame which is pivotally connected by a vertical pin to the base of the ma- 'In suitable bearings of this fra-me a is mounted a horizontal shaft Z), which has secured to it a pulley c, to which motion is transmitted from any suitable driving mech-A anism. Fixed to the shaft b is a Worm d, en.-

40 gagingy a .ivorin-gearpf. The said gear is'- mounied on the vertical shaft e. Near the left end of the shaft b .is arranged a bevelgear g, which engages the horizontal bevelgear g', loosely mounted on the pin a: and

bodily connected to .the toothed Wheeljgz.

Parallel to and in the same plane with the frame a is arranged a second frame k, rotatably mounted Aon .the vertical pin This frame k supports' the. shaft 7,', which is con- 5o nected by the ,gears h h h2 with the toothed 'wheel g2. l In moving the frame t on its pivot the bevel-gear hjrefvolves about the bevel-4 l the shaft i.

gear h', so that in every position of the frame It the rotation of the shaft b is transmitted-to. l is a bevel-gear secured to the shaft-z'. gear m, fixed toitheyertical shaft n; The frame lc is provided with an annular p art o, inelosing the enlarged Vhuhof a toothed wheel p. The said wheel may be`rotated in the` The said gear meshes with the-bevel-v part o, on which it rests and meshes with a toothed wheelsof the vertical shaft n. Thus, as will be seen, the rotation of the shaft b will impart motion to the wheel p. The wheelp is provided with an opening q to receive the leaf metal q', which is supported on an anvil a'. By means of this construction the hammer will not strike the wheelp at`its downward stroke, While the work maybe moved abouton the anvil by shifting the position of the wheel p by means of the part oA of the frame It.

t is a'cain-d-isk secured .to the vertical shaft e. A roller fu, pivoted to a lateral arm of thev frame c, is held in Contact with the'camdiski by means of a weight u, secured to one en d of a suitably-guided'chain, the other end o f which is connected to the frame k.

It wil-[thus be seen that the frame k will -be swung on its pivot when-the cain-diskt is set in motion, whereby the part o and the wheel p and the Vwork q will be reciprocated. At the same time' the gears l m s transmit motion from the shaft z' tothe toothed wheel A 1p; 4'lhecam-diskif is so timed as to impart,

together with the Vwheel'psuch movement to the work q' aswill cause it to present to the 'hammer 8 only such part of the surface as is necessary for eecting the preliminary work` ing of the metal.

`@uis a cam-disk on the vertical shaft n;I which is heldin -engagement*.with the roller y by means of the Weight u. The said'roller y is mountedin'a slot of the machine-frame and is` seclired therein vby mea'nsof a setf screw, so that igmay'be. adjusted.

For varying the .path of movement of the frame t a set-screws is provided which bears against the side of the frame a and is screwed through a lug secured'to the base of the'machine. 4 The operati on of these devices is as follows: The work q `hearing been placed into the opening of the wheel p,'the machineis started mer is" in contact with the-wo rkisupported on the 'en -vilt; VTheplungerl 6 is provided with transmits inet-ion, by means of gg' g? h2, hVh 1 fm 8, to thewlieel pand tothe work' q'v.'
