IMPROVEMENT IN MOLDiNG-MACHINES.

Specification forming part of Letters Patent No. 179,093, dated June 27, 1876; application filed March 31, 1876.

To all whom it may concern:

Be it known that I, HENRY BUOHTER, of the city of Louisville, in the county of Jefferson and State of Kentucky, have invented a certain new and useful Improvement in Molding-Machines and I do hereby declare that the following is a full, clear, and exactdescription thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming partof this specification.

The drawing is a perspective view of the machine with a part of the-cover and posts left out in order to show the interior arrangement of the several devices under it.

This my invention relates to a new and useful improvement in vertical railway moldingmachines, hung to the frame or beam of the building, with a hinge-joint in the lever-immediately under it, in order to enable the lever to swing or be turned in any direction to form the required style or shape of moldings to be cut, the particular motion required being produced by the shape of the curved way, on which the machine partly rests.

The object of this invention is to provide a machine of universal application, that can be operated in any direction, either to dress the top surface of plane circular pieces or form moldings 0n the edges in a regular curve form, or in a wavy zigzag manner, by the use of suitable cutters on the operatingspindle.

This machine will be found more fully illustrated in detail in perspective view of the drawing, in which- A is the vertical swinging lever for holding and giving direction to the cutter-spindle andv pulley S, which lever is made of wood, provided with suitable metal bearin gs on the lower end to receive the cutter-spindle S, as shown in the drawing. 0 is a curved bar, hinged to the side of the lever A, for the purpose of answering as, the bearing for the end of the cutter-spindle and pulley S, and also as a convenient point in which to insert a handle to operate the machine, and is so arranged as to be drawn out, for convenience in changing on p the spindle and pulley S. Uis the operating handle. P is a lever for assisting in steadying the machine while in operation. Q is the stand, through the central part of which the lever P is made to pass loosely, so as to turn with the motion of the machine. Ris a brace for supporting the curved bar 0. S is the cutter-spindle and pulley by which it is driven, the'cutters not being shown on the spindle. T is a sheave, working in bearings under the spindie S on the lower end of the lever A, and is made to work on the curved way, by means of which form is given to the article'to be operated upon. V is the block and curved way on which the machine rests, in part, and by which it is guided in its operation. This last-named curved way V is intended to be changed in form to suit the kind of molding to be cut. W is a block, upon which the article to be operated upon is placed, and is held in its place by the jaw X, when closed upon it by the screw Y. Z is the table, 011 which the machine rests, which is made in form as shown in the drawings. Z is the treadle for raising the machine in changing the article under it. B is a metal flange or head-piece on the upper end of the swinging lever A, constituting a part of the hinge-joint attachment to the clevis above. 0 is a clevis-shaped blockof metal, arranged to receive the driving-pulley shaft D D by means of bearings formed in the arms below, as shown in the drawing. The ends of these arms below the bearings constitute the flanges of the hinge-joint of the lever A. D D are the driving-pulleys, by means of which motion is transmitted to the cutter-spindle and pulley S below. N is the main pulley, for driving the machine. E is the guiding-spindle at the top of the machine. G is the collar, by which the device is hung upon springs, to regulate the weight on the cutters. F F are pins passing up through the beam into a plate above, through which the spindle E passes, and are used as a means for raising the machine when required. H is the lever by which they are operated. I l are springs 'for regulating the weight on the cutters. J J are bars hinged to the bearings of the clevis, to counteract the lateral strain caused by the driving-belt. These last-named bars are also hinged to the cross-bar K at the other end, so as to yield to the change of position in operating the machine.

L is a spring for adjust- 4 pulle; S, sheave '1, and handle U, when arranged, constructed, and operated substantially as and for the purpose herein set forth.

2. In combinationvwith the vertical swinging lever A, above described, the headpiece B and clevis O, with its pulleys D D, spindle E, pins F F, collar G, lever H, springs I 1, bars J J and K, springs L, and cord M, when arranged, constructed, and operated substantially as and for the purpose herein set forth.
