FARRlERY-MACH-INE.

SPECIFICATION forming partlof Letters Patent No. 718,271, dated January 13, 1903.

Application filed April 21| To all whom t may concern,.- I

Be it known that I, SAMUEL J. MCDONALD,a citizen of the United States, and a resident of Gallatin, in the county of Daviess and State of Missouri, have invented new and useful Improvements in Farriery-Machines,of which the following is a fl'ill-,clear,and exact description.

My invention relates to a machine especiallyadap'ted for use by farriers and others in the making of horseshoes; and the primary object that I have in view is the provision of means by which either a plain-toed shoe or a clip-toed shoe may be produced in an easy and quick manner.

A demand exists among farriers for a simple, strong, and compact machine which will hold a horse or mule shoe in a position convenient to the Workman in finishing up any portion of a horseshoe, either the plain-toed shoe or the shoe having a toe-clip, and also to iinish an outwardly-standing call; at the toe of the shoe, as well as the heel. -My improved machine enables these operations to be performed and also allows the heel-calks to be bent and various other kinds of work to be carried on. The machine can be used to such advantage that shoes of better quality and superior Iinish canbe produced, because the shoe retains its full strength and has smooth even surfaces.

.Further objects of the invention are to provide for the relative vertical adjustment of the vise-jaws, so as to accommodate dierent thicknesses of toe-calks andshoes, to secure the parallel relation and movement of the movable jaw at all times to the stationary jaw, to provide improved means Vfor operating the vise by hand or foot power, to enable the Working parts to be rotated so as to bring them to any desired or convenient position and also to allow the said working parts to be dismounted and laid aside when not in use, and, finally, to simplify and improve the construction, so as to secure strength and durability and a high degree of efficiency in operation.

lFurther objects and advantages of the invention will appear in the course of the subjoined description, and the actual scope ofthe invention will be defined by the claims.

Reference is to be had to the accompanying 1902. Serial No. 103.931. (No model.)

drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in'all the figures.

Figure l is a side elevation of my improved horseshoe-making machine adapted for use by farriers and others, the vise-jaw being opened and the swaging-die being moved to its inoperative position. Fig. 2 is a sectional elevation showing the vise closed and the swaging-die moved or adjusted to the operative position, the lower part of the machine being partly broken away and insection in order to represent certain features 'of construction more clearly. Fig. 3 is a plan view, on an venlarged scale, of the upper part of the machine. Fig. 4 is a vertical transverse detail section taken in the plane of the dotted line 4 4f of Figpl; and Fig. 5 is a sectional plan through the lower part ofthe machine,v

taken in the plane of the dotted line 5 5 of Fig. l.

In carrying my invention into practice I employ atubular standard or post 5, which may be of any desired diameter and height, in order to present the operative parts of theimproved machinein a position convenient to the blacksmith for use. This post or standard may be mounted or'supported by any suitable means, but I prefer to support said post by means which permits it to turn on a vertical axis. One means for accomplishing this end is a base 6, having a collar 7 and an upstandihg spindle 8. The base may be of any desired form and size, and it may be secured firmly in place on the floor or to any other surface by approved means. The spindle 8 is of a desired diameter and length to t -snugly in the lower open part of the hollow column or post, and 'the collar 7 of the base exceeds the internal diameter of said post in order that the lower extremity of the post may bear firmly upon said' collar, as shown more clearly by Fig. 2, whereby the end thrust or pressure of the column 5 willbe taken up by the annular collar and transmittedvto the broad or wide-base 6. This construction allows the post and column 5 to turn freely on the base. The end thrust or pressure of the column is absorbed or taken up by said base, and the column, with its contained operating devices, may easily be removed from the base and its spindle when it is not desired to use IOO the machine, thus allowing the base to remain ixed in place on the door or other surface, and the machine may be used simply by replacing the column on said base.

One of the important features of my invention resides in the employment of an anvil which surmonnts the post or column 5 andis disposed to bear directly thereon. This anvil 9 may be of any desired form and size, but, as shown by Fig. 4, I prefer to seat the anvil in a recess or socket 10, which is provided in an anvil-block 11, the latter having a depending stem 12, whereby anvils of different configurations may be used interchangeably in the same anvil-block 11. The stem 12 is fast or integral with the anvilblock and extends below the same in order that the stem may extend well into the hollow column or post, while the anvil-block ll is adapted to restdirecrly upon the upper eX- tremity of said post. The stem 12 is provided with a series of perforations 13, into either of which may be thrust apin 14, which lies below the collar or block 15, that is fitted on the stern and is adapted to assist the post in supporting the horizontally-slidable jawcarrier of the vise. The upper portion of the standard is provided with parallel slots 16, which extend transversely through the standard and lie above the collar or block 15, as shown by Fig. 4, and through these slots pass the members or side portions 17 of the slidable-jaw carrier 18. This jaw-carrier is made r formed of a single piece of metal and is provided with a slot which extends nearly its full length, said slot being indicated at 17` in Fig. 3 and forming the parallel side members or portions 17, the same adapted to extend loosely through the slots 16 of the hollow column and to lie between the block or carrier 15 and the bottom face of the anvil-block 11. This jaw-carrier is provided at one end with a vertical socket or opening adapted to receive the shank 19 of the vise-jaw 20. The jaw-carrier 18 is furthermore provided with a depending guide or brace portion 21, which has its active face disposed in the vertical plane of one side wall of the socket in said jaw-carrier, and against its depending guide or brace 2l is adapted to bear the shank 19 of said visejaw. The provision ofthe shank on the visejaw allows the jaw to be raised or lowered with relation to the anvil 9 and the anvilblock 11, and this jaw 2O has one face thereof disposed in cooperative relation to an opposing face of the anvil and the block, thus making these parts cooperate to form the vise. The shank of the movable jaw may be secured adjustably in the jaw-carrier by any suitable means; but, as shown by Figs. l and 2, I employ a spring key or wedge 22, which is inserted between the outer face of the jawshank 19 and one wall of the socket in the jaw-carrier 1S. If desired, however, the

well-known equivalent of the wedge may be employed-that is to say, one or more setscrews may be mounted in the jaw-carrier in position for engagement with the shank 19 of thejaw-and, furthermore, the key 22 and the set-screws just described may both be employed, if desired.

The jaw 20 is considerably wider than its shank 19; but, as shown by Fig. 3, this jawis not as wide as the anvil-block, although the relative proportions of these parts may be varied.

By referring to Figs. 1 and 2 of the drawings it will be seen that the jaw-carrier 18 is mounted in the slotted upper part of the column t'or movement or' adjustment in a path parallel to the horizontal plane of the anvil, and this jaw-carrier supports the movement of the vise-jaw, which is disposed in a vertical position adjacent and parallel to one of the edges of the anvil or anvil-block. The described arrangement of the parts causes the jaw-carrier to hold the vise-jaw 20 in parallel relation at all times to the anvil, the latter forming the stationary jaw of the vise, and this construction enables the vise to hold the horse or mule shoe in a proper shape while the toe is being 'welded on, so that the shoe may be perfectly true and level when it is removed from the vise. Furthermore, the jaw 20 or the anvil may be adjusted in a Vertical direction, and if the vise-jaw is adjusted it may be tightened to the desired position by the key or wedge 22. This is an important feature of my construction, because the vise-jaw must be raised or lowered to suit the'diierent thicknesses ot toe-calks and shoes and at the same time to prevent the shoe during Welding of the toe portion thereof from doubling in a backward direction when the toe portion is being iinished orwhen the clip or lip is being formed thereon. It the two jaws met each other in a flat form on top, the shoe would be liable to clench over on the back part thereof, thereby spoiling the shoe and preventing it from properly fitting the animals foot.

I have also equipped the improved machine with means for adjusting the jaw-carrier and jaw by foot or hand power, and one embodiment of such means is shown in the accompanying drawings as a treadle mechanism, although it is evident that a hand-lever may be employed in lieu of ,the foot-lever; but these devices are mounted on or supported wholly by the hollow column or post 5, so as to be removable and detachable therewith. A lever 23 is disposed alongside of the standard at the upper part thereof, and this lever is curved to provide a cam-shaped edge 23a, adapted for engagement by a locking-link 24, to be presently described more fully. This lever is fulcrumed at a point intermediate of its length in the bifurcated end 25 of a bolt 25, by means of a fulcrnm-pin 26, said bolt 25 passing through suitable openings in the standard or post 5 and through one of the openings 13 in the depending stem 12 of the anvil-block 11. (See the dotted lines in Fig.

2 and the full lines'in Fig. 4.) The upper short arm of the lever `23 is connected by means of a pivotal bolt 27 to the free ends of the side portions or members 17 of the horizontally-slidable jaw-carrier 18, and this jawcarrier and the lever are thus operatively connected together in order that the movable vise-jaw may be adjusted or controlled by said lever 23. A spring 28 is arranged to bear against the long arm of the lever 23 in a manner to force said long arm in an outward direction, and thus make the short arm move the jaw-carrier and the jaw away from the anvil-block, said spring 28 being heldvor confined on the standard or post 5 by the solid partof the head 25, which forms a part of the bolt 25.

To the lower end of the actuating-lever 23 is pivoted, as at 29, a draw bar or'link 30, which is arranged loosely in a slot which is formed in the postk 5 at a point above'the spindle 8 of the base, and the other end of this link is pivoted, as at 3l, to the upper extremity of a secondary lever 32, said lever being fulcrumed, as at 33, in the bifurcaied end 34 of the bolt 35, which passes through the post or column 5 at a point above the extremity of the spindle 8. The foot-treadle 36 is bent to form the arm 36, which is pivotally connected, as at 37, to the lower eXtremity of a carrying-plate 38, said carrying-plate being secured firmly to one face of the stand'- ard and receiving the nut on the bolt 35. The angular arm'of the treadle is provided with a transverse bolt 39,` which 'receives one end of the pair of links 40, which are disposed on opposite sides of the post 5 and the spindle of' the base, as shown by Fig. 5, and the other ends of the links 40 are connected by the bolt 4l to the lower portion of the secondary lever 32, whereby the treadle has operative connection with the lever 32 for the purpose of actuating the levers 32 23 andthe link 30 against the energy of the spring 28, thus imparting slidable movement to the jawcarrier 18 and bringing the vise-jaw 20 into cooperating relation to the anvil.

The treadle 36 carries an adjustable footpiece 42', which is provided with a clip or band 43, arranged to embrace the treadle and to be held at dierent points thereon by any suitable form of fastener, such as the key or wedge 44. (See Figs. 1 and 2.)

45 designates a swage-block which is firmly secured to a bent or curved arm 46, the latter being bifurcated, so as to produce the branches 46, which have their en d portions loosely fitted on the bolt 27, the latter connecting the lever 23 and the slidable jaw-oarrier 18, whereby the curved arm of the swageblock is pivotally connected to the jaw-carrier by the same bolt 27 which connects said jaw carrier and the primary lever 23 together. This swage block andV its curved arm 4b' may be turned in an upward direction, so as to make the swage-block overhang the anvil in the position shown by Fig. 2, thus disposing the'swage-block into cooperative relation to the anvil for the purpose of iin-A ishing the toe-call; andthe upstanding lip or clip on the shoe, as will be understood by farriers. OnV the other hand, the arm 46 may be turned in a downward direction to assume the position shown by Fig. 1, and the swageblock 45 may thus assume an inoperative relation'to the machinewhereby the block is adapted to serve as a support or ltable for holding a pair of tongs or any other tool.

In using the improved machine the toe is frst welded to the shoe and the latter is then Vvise-jaw. This swage is an important addition to the farriery-machine, because it enables the toe to be finished in a superior 'mannerp Itis evident that the active face of the swage may be ofV any ornamental character by providing grooves or diamond points on said face, and' this pattern-face of the swage will be imparted to the shoe and its calk.

IOO

My invention contemplates the employment of different kinds of anvils adapted for weld ing different sizes of sharp toe-calks to shoes, said anvils being used interchangeably in the anvil-block. Y

The jaw-carrier is adapted to slide in a straight -line below the anvil, and this adaptation makes the movable jaw 2O come np square against the opposing face of the anvil-block.

This is an advantageous feature, because it prevents thejtop face of the vise from cutting into the bottom of the shoe, and thus the bottom of the shoe is left in a perfectly smooth condition, and at the same time the shoe is adapted to be firmly gripped by and between the jaws of the vise.

The ring or link 24 is adapted to be dropped to an operative position, as shown by Fig. 2, wherein itengages with the curved edge 23 of thelever and with the post or column 5, so as to lock the lever against movement and preventthe vise-jaw from having accidental displacement away from the anvil, thereby making the vise firmly grip the work. At the same time the link 24 may be raised on the post to the position indicated by dotted lines in Fig. l, said link being held in its inoperative position by the nut on the bolt 25, that supports the primary lever 23.

It is evident that the active faces of the anvil 9 and the swage-block 45 may be smooth and straight, as shown by the drawings, or that any desired form or contour may be given thereto-as, for example,said parts may IIO IZO

have corrugated active faces adapted to impart an ornamental crimped appearance to the toe or heel calks, as may be desired.
