Application filed May 5,1902. scan No. 105,961. (No model-l T0 (tZl whmn it Tit/Ly concern.-

Be it known that 1, ANDREW KIMBLE, a citizen of the United States of America, and a resident of Zanesville, in the county of Mus- 5 kingum and State of Ohio,ihave invented certain new and useful Improvements in Shaping-Machines, of which the following is a specification.

This invention relates to certain improveand more especially in that class of shapers which are adapted for use in forming articles of irregular shapes-such as vehicle-axle caps, for example; and the object of. the invention is to pro vide a device of this general character of ta simple and inexpensive nature and of a strong and compact "construction which shall be adapted for convenient and rapid operation without requiring any particular skill or care on the part of the attendant for turning out perfect work.

I The invention consists in certain novel features of the construction,combination,and arrangementof the various parts of the improved'shaping machine whereby certain im-' portant advantages are attained and the device is made simpler, cheaper, and is other-g wise better adapted and made more conven-. ient for use, all as will be hereinafter fully set forth. i p

The novel features of the invention will be carefully defined in the claims.

In the accompanying drawings, which serve to illustratemy improvements, Figure 1 is a side elevationshowin shaping machine constructed according to my invention, and Fig. 2 is a plan view of the improved machine. 1

Fig. 3 is a vertical section drawn to an enlarged scale and taken transversely through the machine in the plane indicated by the line a a in Fig. 2.

the improved machine inthe plane indicated by linebb in Fig. 1. Fig. 5 is an enlarged partial section 'taken vertically through the machine in the plane indicated by line 0 c in Fig. 2 and showing certain features of the feeding mechanism to be hereinafter referred to. Fig. 6 is an enlarged partial section taken vertically through the improved machine in the plane indicated by the line d din Fig.1 and showing thespring mechanism for holdand 4. 'yokes S and 9, the upper and lower ends of a is a vertical section", also drawnto an enlarged scale, but taken through other. Fig. '7 is a partial detail view showing one of the bearings for the cutter-head spindles of the machine.

As shown in the views,the improved shapingmachine comprises a' frame formed of side pieces 1 1, spaced apart and supporting tables or work- rests 2 and 3 at their upper parts the tables or rests 2 and 3 being alined in the same horizontal plane and the table 2 being at the receiving end, while the table 3 is at the discharge end or side of the machine. From the discharge end or side of the machine are extended bars 4 i, held by bolts or the like to the side pieces 1 1 of the frame at the upper parts thereof, with their opposite ends arranged to converge at an upright 6 in linewith the center of the machine-frame. Between the bars 4 4: are extended Wooden strips 5, forming a continuation of the table or rest 3 at the discharge side of the machine.

If desired, the table or. rest 2 may also be provided with a similar continuation.

The upright 6 is made with an overhanging upper 611Cl5l10 which the extremities of the bars 4 4 are bolted or otherwise secured, and said upper end of the upright is extended toward the frame of the machine and serves as a support fortheupper end of a vertical shaft or stud 7, the lower end of which is stepped in the foot Of'thG upright, as shown in Figs. 1 The shaft or stud 7 serves to receive which are bent sidewise as shown in Fig. 4', and 'areformed with openings for the passage of said shaft or stud, so that the said yokes are-pivotally held for swinging movement upon the said shaft or stud and areadapted to be swung toward and from each other in horizontal planes. The bent upper and low er ends of the yoke S are arranged to engage the shaft or stud '7 above and below the corresponding ends of the yoke 9, so that the yckes may not interfere one with-the other in their swinging movements. 1

Each of the yokes 8 and 9-has at its upper and lower ends arms 10 10, which are extended in horizontal directions toward the machineframe, and said arms 10 are of such lengths that their free extremities are extended in the space between the side pieces 1 1 of the machine-frame. The arms of the yoke 8 are ing the cutters normally pressed toward each above and below, respectively, those of the yoke 9, but immediately in front of the machine-frame,the upper arm of yoke 8 is bent or curved downward, so as to be in the same horizontal plane with the upper arm of the yoke 9, as shown at 10, and at corresponding points said upper arms of the yokes 8 and 9 are formed with openings in line with each other and through which is passed a belt or bar 21, the extremities of which are extended on opposite sides of said arms, as shown in Figs. 1 and 6, and carry coiled springs 23, backed by washers and nuts 22 and arranged to press upon the outer sides of the respective arms 10 in such a way as to hold said arms normally pressed toward each other, while permitting the arms to be pressed against the tension of said springs away from each other,

the yokes 8 and 9 swinging when said arms are thus pressed away from each other upon the shaft or stud 7. The nuts 22 permit of adjusting the tension with which the springs act to press the arms 10 toward each other.

, ings 11 is illustrated in Fig. 7, which is a secframe between said tables or rests.

tional view taken transversely through one of the spindles above its lower bearing 11.

Upon the upper sides of the upper bearings 11 of the spindles are carried fiat-topped plates or carriers 1i ofrectangular form, the upper surfaces of said plates being in the same plane with the tables or rests 2 and 3 of the machine-frame and being arranged in a'space or opening 15, extended transversely of the Upon the plates or carriers 14 are provided guides 19, which project above the surface of the plates and are, as herein shown, made in the form of raised bosses concentric with the spind les 1.2 and on the upper surface of the plates 14. The spindles 12 carry above said raised guides 19 cutter-heads 18, which may be of a Well-known construction removably held on the spindles.

The lower bearings'll of the spindles 12 are provided, respectively, with wheels or rollers 16, arranged to travel on a track or Way 17, produced upon a brace or cross-girth of the machine-frame. In this way it will be seen that the free ends of the arms 10 of the yokes 8 and 9 are firmly supported on said track or way 17 and are permitted to move freely toward and from each other to permit the cutter-heads 18 18 to be moved toward or away from each other in the operation of the machine, the rollers or wheels 10 traveling upon the track or way 17 when the said arms 10 10 are swung toward and away from each other.

Upon the plates or carriers 14 are held plates 20, forming guides for carrying away the chips and shavin from the cutter-heads 18, so that these will not accumulate and in terfere with the operation of the cutters.

The spindles 12 12 are adapted to be driven by crossed belts or bands passed around the sheaves 13 on said spindles and extended toward the upright 6 and on opposite sides of the arms 10 and around pulleys 2 1 24, held on a counter-shaft 25, journaled in suitable bearings between said upright 6 and the machine-frame and provided at one end, as shown in Fig. 2, with tight and loose pulleys 26, by means of which it may be driven from any source of power.

At the sides of the machinevframe are arranged similarly-formed brackets 27 27 ,which are held upon and extended above the upper surface of said frame, there being two pairs or sets of these brackets, one pair at the front and one at the back of the space or opening 15 between the tables or rests 2 and 3 of the frame. Each pair of brackets 27 is formed with correspondingly-arranged guideways or openings 28, in which are held for vertical movement blocks 29, in which are journaled the ends of the shafts 011 which are carried pressure-rollers 30, the pressureroller at the front side of the opening-15 being grooved or fluted to permit it to more effectually engage the work to be fed into the machine.

In the side pieces 1 1 of the frame beneath the guideways 28 are other blocks 31, in which are held the ends of shafts whereon are carried the lower feed-rollers 32, alined vertically with the respective upper rollers 30 and in line with the tables or rests 2 and 3 of the machine-frame. The shafts of the upper feed-rollers 30 are extended outside the side piece 1 at one side of the frame and carry toothed gears 33, arranged to mesh with pinions 34, carried on studs held by links 37, swinging on the shafts of rollers 30 in a wellknown way, and said studs are also arranged to receive the ends of other links on which are other studs carrying spur-gears 35, as shown in Fig. 1, the studs of these latter spur-gears being also loosely engaged with links extended from and swinging upon the extended ends of the shafts of the lower feedrollers 32 at that side of the frame, which shafts of the lower feed-rollers also carry gears meshing with the spur-gears 35 in such a way that the upper and lower feed-rollers 30 and 32 are caused to' turn in unison. The arrangement of links on which the studs of the intermediate gears 34 and 35 are held is a well-known one and is designed to hold the gears in mesh, while permitting vertical adjustment of the upper feed-rollers 30 with relation to the lower rollers 32.

At the side of the frame opposite to the gearing above described the ends of the shafts of the lower feed-rollers 32 are also extended beyond the side piece 1, as shown in Figs. 2 and 3, and are provided with spur-gears 38, which mesh with an intermediate pinion'39 on a stud central on the frame between the two lower feed-rollers. Said stud also carries outside its pinion 39 a gear-wheel 40, in mesh with a pinion 41 011 the extended end of a machineshaft 42, journaled transversely of the frame i and having at the side of said frame opposite to the gearing last described a band wheel or pulley 43, loose 011 the shaft, and a clutch device 44, actuated by a lever 45 and adapted for use to lock the said pulley upon the shaft 0 for driving the feeding-rollers The band wheel or pulley 43 is adapted to receive a belt or band, which is extended toward the counter-shaft and passed around a pulley 46 thereon in such a way as to permit the movement of said counter-shaft to be transmitted to the shaft 42.

To provide for vertical adjustment of the upper feed-rollers to accommodate work of different thicknesses, the blocks 29, wherein the shafts of said upper rollers are journaled, are formed with extensions 47, having interiorly-screw-threaded openings, in which are engaged screw-threaded shafts 48, extended Vertically at the sides of the machine-frame,

with their upper ends passed through openings in the tops of the brackets 27 and their lower ends engaged upon rests 48 011 the side pieces 1 1 of the frame. The upper extended ends of the shafts 48 carry bevel-gears 49,

r 1 i meshing with similar gears 50 on the ends of cross-shafts 51, held to turn in bearings 52, extended up from the brackets 27 and extended across the top of the frame, as shown in Fig. 3. The shafts 51 have centrally-a1- ranged hand-wheels 53, by means of which they may be turned, and each shaft has its opposite ends geared with the screw-shafts 48, engaged with the blocks 29 at the ends of one of the upper feed-rollers 30 in such a way that i when said shaft 51 is turned the said upper feed-roller is raised or lowered. The rests 48 form stops to limit downward movement of the shafts 48, so that the upperrollers may not fall below the level for which they are adjusted; but the construction is such that said rollers may be allowed to rise to permit the work to be passed beneath them, and in order to place a suitable tension upon the rollers to hold them pressed down upon the work I con- .nect the lower end of each shaft 48 with a lever 54, one end of which has pivotal connection with a side piece 1 of the frame, as shown at 55, while the opposite end thereof is extended beyond the frame and has connection with the lower end of a link 60, to the upper end of which is connected an arm 61, extended from a rock-shaft'62.

extended across the space between the side pieces 1 1. of the frame and serves to connect the lever mechanisms for the shafts 48 at the ends of each of the respective upper rollers, so that said mechanisms may move in unison. Weights 63 are hung upon the levers 54 and serve to hold the shafts 48, and consequently Each rock-shaft 62 is the upper feed-rollers, normally drawn down ward. To permit of raising the fluted upper roller 30 at the front or feeding side of the machine in order that the work may be applied readily under the same, I provide a treadle-lever (i5, pivoted at the front of the machine imposition to be conveniently pressed by the foot of the attendant and connect said lever by means of a link 64 with one of the levers 54 in such a way that when the treadlelever 65 is pressed by the foot of the attendant the levers 54 are moved against the impulse of the weight 63 and the shafts 48 and roller 80 at the front of the machine are raised. In the operation of the machine the work which will be attached to the upper face of a pattern corresponding in contour to the outline which it is desired to impart to the finished work is applied under the forward upper roller 30, which may be lifted by means of the treadle for this purpose, and when gripped by said roller said work will be drawn into the machine and applied between the cutters 18 on the upper ends of the spindles 12 12, the pattern at the same time engaging the raised guides 19 of the respective plates or carriers 14 and serving to regulate the approach of the cutters toward each other. The cutters 18 being carried 011 the spindles 12, which are held to turn in the arms of the swinging yokes 8 and 9, will be moved toward and away from each other by the engagement of the pattern to which the work is secured against the guides 19 19 in such a way that the cutters will be caused toimpart to the work held on the pattern a reproduction of the contour of said pattern, moving toward and away from each other as the arms are forced apart by the pattern or drawn together by the springs 23, and the cutters being at the same time supported by the engagement of the rollers or wheels 16 with the track or way 17, so that they are prevented from moving vertically.

From the above description it will be seen that the improved shaping-machine is of an extremely simple and inexpensive nature and is especially well adapted for use, since it is strong and campact in construction and does not require any special skill or care on the part of the attendant beyond the securing of the work to the pattern and applying it between the feed-rollers, so that it may be drawn into the machine. The machine is also of such a construction as to adapt it to various kinds and sizes of work without any special adjustment being required, except such adjustment as may be needed to cause the feed-rollers to press with proper force upon the work, and it will be evident that the machine although specially designed for use in forming vehicle-axle caps is not limited in its use to work of this special kind.

It will also be obvious from the above de scription that the improved machine is capable of some modification without material departure from the principles and spirit of the invention, and for this reason I do not wish to be understood as limiting myself to the precise form and arrangement of the several parts as herein set forth.

Having thus described my invention, what I claim, and desire to secure by Letters Patcut, is

1. In a machine of the character described, the combination of a frame, an upright stud alined with the center of said frame at one P end thereof, yokes each pivoted on said upright stud and having upper and lower arms extended from the stud beneath the frame and movable in a direction toward and from each other, means for feeding material over the frame, cutters having spindles carried by the arms of the respective yokes, said cutters being arranged in position for engagement with the sides of material passed over the frame, means for driving the cutters, bars extended from opposite sides of the frame at angles to each other and having their ends secured to said stud, and strips extended across the space between said bars and forming an extension of the frame, substantially as set forth.
