U ITED. STATES SPECIFICATION forming part of Reissued 'Letters Patent No. 9,358 dated August 31,: 1880.

Original No. lT'JJnlZl. llli l'tl June .37, 1876.

To all it'll-om it may concern Be it known that [,ll'nmrr Bucn'mn, of

the city of Imuisville, in the county of 'Jetfew son and State of Kentucky, have invented a certain new nndusetul Improvement in Mold in g-lliuchiues; and l do.l|ereb y"declme that the l'ollowii'lg is a full, clear,and'esuct description". thereof, which will enable others skilled in the art to make and use the'sanie, reference being bad to the zuzwmpuuyiug dinning, forming; part of this spwitieation.

The drawing is u-' perspective view-of tlief beam of. the building, with'a'hiugejoin't in the lever immediately under .it,- in order to enable the lever to. swing or be turned in nuy'direction to form the required style or'shape of moldings to be cut, therpurticuilar mot-ion "required .beil produced by the shape of the curved way on which the machine partlyrests.

The objectof this invention is to provide a machine ot universal application that can-be o iemted inanyfllirection, either to dress thetop surface of plane circular pieccs orfor m moldings on the edges in a regular curve form or in a wavy zigzag manner bythe use of'suitable cutters on the operating-spindle;

In the drawing, A is a vertical swinginglever forholding and giving direction "to the cutter-spindle S audits pulley S, whichlever is made of wood m d-prm'idcd with suitable metal hearings on the lower end 'to receive the cutter-spindle, as shown.

"J J are bar's hinged to the beafings of the clevis to counteract the lateral straincaused by the driving-belt. These last-named bars are alsohinged to the cross-bar K at the other end, so as to' yield to the change or position in operating the machine.

M is a cord connecting the lever 11 with the treadle Z',.'for use in raising the machine to change, insert, and remove the article to be operated upon.

My machine being constructed as above described its operation .is as follows: Motion maybe imparted to the cutter-spindle S by means of a belt over the pulleys S and D and connection with the main driving-pulley N. Thematcrial tribe operated upon is clamped upon the bed W, and the swinging lever-pulley T rests upon a former or curved way, A, of substantially the outline or profile of the finished article. Cutters suitable for the work to be done having been placed upon the cutter-spindle in the end of the swinging lever and motion imparted to the cutter-spind1e, the swinging lever is moved over the material by means of the handle U until the cutters give to the article the profile formed in the curved way A. The swinging levcrbeing'jointed at D, and also being rotatable on the pin E, sulfieient latitude of movement is given to-permit the proper'manipulatiou ot' the cutters. The swinging lever is upwardly movable by means of the leverH,eonnected by cords M with the treadle Z, said lever operating uponthepius F, which are inserted in the beam through which the pin E passes and suspends saidlever. The gnideway A determines the shape of the finished article, and is changeable to adapt the machine for a variety of work. The springs I, from which the lever is suspended, afford a yielding bearing, whereby the cutters are saved from injurious shocks and permitted to work easily over the material. V

Having thus fully described the nature and .object of this my invention, what I claim as new, and desire to secure by Letters Patent, is I 1. In a vertical swinging molding-mmzhiue, the combination of the lever A, curved bar 0, and lever P, with its stand Q, brace R, tool or cutter spindle and pulley-guide roller T, and

handle U, constructed and arranged to operate substantially as and for the purpose set forth.

2. In combination with the vertical swinging lever A, the head-piece B and elevis O, with its pulleys D D, spindle E, pins F F, col- 5o lar G, lever H, springs I I, bars J J and K, springs L,'an d cord M, arranged to, operate substantially as and for the purpose set forth. 3. In a vertical swinging molding-machine,

a. jointed lever suspended upon yielding bear- 5 5 way, A, to govern the shape of the article,

substantially as described.

4. A swinging cutter-holding lever, "in eolirbiuatiou with a pin, E, an adjustable collar, G, and springs I, forming adjustable springbearings therefor, substantially as described. 6g 5. The combination of a work-holder, aver-- tically-movable cutter-holder, and means to. support the same with pins F F, a lever, H,

cords M, and treadle Z, for raising the cutterholder from the work-holder to permit the in-v 7o scrtion and removal of the work, substantially as described. 6. A swinging cutter-holding lever and means for suspending the-same, in combina tion with bars arranged in connection therewith 'to counteract the lateral strain of the d rivingbelt, substantiallyas described.

7.The combination of a swinging cutter-f I holder, means for suspending the same, barsarranged in connection therewith'to. couuter- 8o act lateral strain, a cross-bar for connecting the first-named bars to admit-of change of position, and a governing-spring, L, substair,

tiall y as described.

To theabove specification of my invention I have signed my name this 6th day of J ill-5 A. D. 1880.
