Application 1ed September 7, 1906. Serial No. 333,708.

To all 'whom it may concern:

Be it known that I, CHARLES IV. BORG, a citizen of the United States, residing at Rock Island, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Folly-Finishing Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

rlhis invention relates to improvements in machines for shaping, planing or dressing the wooden blanks from which wheel fellies are constructed.

The obj ect is to provide a machine having a carrier of such nature that the curved blanks can be carried continuously in a proper path past a series of cutters arranged to act upon the several faces that require dressing` or planing; the carrier being adapted to support blanks of different curvatures, and the cutters being adjustable so that t-hey can act properly on blanks of a given curvature, and also act on blanks formed on radii of different lengths. i

Figure l is a plan view of a mechanism embodying my improvements; Fig. 2 is a side elevation of the machine; Fig. 3 is an end elevation of the frame work with some of th-e parts detached; Fig. 4 is a top plan view of two of the cutter heads, and showing also some of the adjac-ent parts; Fig. 5 is an elevation of the parts shown in Fig. 4; Fig. 6 is a top plan view of the cutter head which acts on the inner or concave side of the blank; Fig. 7 is an elevation of the same;

' Fig. S is a detail view, partly in elevation and partly in section, showing the manner of supporting the ring-like carrier. Figs. 9 and l0 are cross sectional views, taken on different planes, of the felly section produced by the machine illustrated in the other views. Fig. ll is a plan view of a portion of the finished felly section.

In the drawings 1 indicates the main base plate, it being preferably substantially` of the conformation shown, having a main rectangular portion and a laterally projecting triangular part at la. Upward from this base plate there rises the standard or upright 9., supported on the aforesaid laterally projecting part of the base frame.

I3, 4, 5 and 6 indicate'what may be considered a box-like frame, the said numerals indicating the several side walls, respectively.

All of the parts referred to, the base, the upright, and the box frame may be cast integral, or this part of the structure may be built up of several elements if preferred. And with respectto them there can be such variation or modification as is desired.

At 7 there is a vertically-arranged plate or frame piece extending from the side wall 3 to the wall 4, and tying them together, either being made integral therewith or secured thereto. It is shown as located at or near the center of the space or chamber below the table. It is used to support a number of the parts which will be hereinafter referred to.

At the upper ends of the parts referred to, and shown at 3, 4, 5 and 6, are placed the

table sections

8 and 9. The section at 8 lies immediately below the path of the blanks and serves to support them during the initial part of their travel through the machine. This table section 8 is vertically adjustable to provide for varying the depth of the cut effected by the lower knives, to be later described. The table sect-ion at 9 is also supported on the upper edges of the side parts 3 and 4 of the frame. It provides a support for the articles acted on by the machine during the latter part of their travel through it. At its receiving end this table section 9 is elevated somewhat relatively to the upper' face of the section 8, in order to properly rec-eive the blank after the action of the under-cutters.

l() indicates a table section which is adjustably mounted on the table section 9, it carrying some of the operative parts of the machine, which will be described below.

l1 indicates a curved metallic arm substantially semi-circular in outline, and having its ends bolted to one of the vertical. walls, that at 3, of the box frame above referred to. It extends to and rests upon the standard or post 2, above described, and serves to hold the outer half of the rotary carrier which supports the blanks and carries them through the machine past the cutters.

l5 indicates as an entirety the rotary carrier, or feed ring as I term it, for the blanks. It is mounted and supported upon the parts above described. It is not formed with a hub, and lacks a center support. On t-he other hand, it is rim-supported, and with it are combined a series of antifriction roller-like holders or bearing devices indi cated by 12-12. This rotating table or feed ring has an upper horizontal part l5,

and a downwardly-extending vertical llange 15". The supporting rollers, or travelers, 12-12 are arranged so as to bear against the outer wall of the flange and lie in horizontal planes just below the planes of the horizontally-arranged.part 15a of the ring or table. The latter is formed with a series of gear teeth which extend horizontally outward in its upper planes. At intervals there are placed Babbitt-metal supporting pieces 13 immediately below the ring. These are secured to, or seated in, the stationary metallic parts immediately below the ring, some of them in the semi-circular part 11, above referred to, and some of them in the table sections on the opposite side of the ring. The under surface of the feed ring contacts with these, and they provide a rigid, though anti-friction, support for the ring, adapted to hold it firmly in 4the lines in which it is desired that it shall rotate. In order to further reduce the friction I provide means for lubricating the under-surface of the ring, and this I accomplish by forming cups or pockets at intervals in the metallic parts below the ring. These are provided with quantities of waste or other lubricant absorbent 13a, Fig. S, and the latter being saturated with oil, the sliding face of the ring, when passing over them, becomes lubricated to such an extent that the friction is largely overcome. To the inner face of this ring are secured the parts that. engage with, hold and advance the wooden blanks. Each of these is indicated as an entirety by 1G. As many of them may be employed as the conditions of the machine will permit; four being illustrated in the construction shown. Each comprises a body part 1G, which is bolted against the ring 15, and a radial shoulder or projection at the rear end, preferably sharpened, or provided with a sharp dog 1Gb, adapted to engage with and grip the rear end of a blank piece, the forward propelling of the blank being accomplished by this inwardly-extending projection or dog on the holder 1G.

The machine which I have devised and illustrated aims to properly shape and dress the sections of wo-od which are used the felly pieces of carriage or ragen wheels, one being shown at 7G in Fig. 11, the desire being to finish the two side faces TT, 7S, of the felly piece which are in vertical positions when the wheel is in use, and the inner arc-like surface 79, and, further, to impart to the wood the curvature in crosssection which is desired at a series of places around the circle, as at 80, S0. The wood blanks travel through the machine, lying in a position at right angles to that which they occupy when in place ou a vertical wheel, and consequently it .is the lower face 77 and the upper face 78 of the blank, (as it lies in the machine), which require dressing and finishing. The cutter which effects the uuder face TT of the wood is indicated as a whole by 17. It is mounted on a shaft 17?, which is ournaled in bearings at 1S, one at each end. These are adjustably carried by vertical slides 18a, tted to guides 18", formed on or secured to the side walls of the box frame above described, adjusting devices suitable for the purpose being shown at 18. Upon the inner end of the shaft 18 is the power-receiving pulley 18d, with which engages the belt 18C, extending to the main countershaft 81. The cutter head which dresses the opposite or upper face of the blank is indicated by 19. This has a shaft 19a mounted in bearings 20a. The bearings 20:l are carried by a frame :2O for supporting the shaft 19a. This bearing frame has a downwardly-projecting slideextension 20h, which is mounted in a vertical slideway on the front face of the transverse plate 7 above referred to. It can be adjusted to and supported in any desired position by means of the adjusting screw 21, provided with a hand-wheel 24 for turning it.

30 indicates a curved bracket arm secured to the aforesaid adjustable table section 10, and extending thence laterally and forward, and then in the opposite direction, laterally, t ansversely of the machine. At its free end it carries an extension bracket 22, the latter being provided with a compressor spring 23 adapted to loosely engage with the wood blank and press it downward upon the table section 8. This spring 23 is adjustable in relation to the extension 22, the latter having a longitudinal slot 22a, and a binding screw 23, for this purpose.

Immediately behind the top cutter head 19, which dresses the upper face of the blank, there is placed a presser bar 25. 1t is supported from two arms 25a, which extend rearward from the bearings 2Oa of the upper cutter. @(3-26 are supportiiig-and adjusting screws extending vertically through these projecting arms, and carrying this presser bar 25. By turning the screws in one direction or the other, the bar can be raised or lowered, as desired. On the same arms 25a, extending from the bearings 20a, is supported the chip breaker. This is indicated by 27, and as concerns its operative parts it may be of any well known form. As shown, it is carried by arms 27 which extend backward to and are pivoted at Q71 above the projections 25a. 1t is provided with one or more adjustable weights 28 by means of which the downward pressure upon the wood can be varied, as desired. To keep the blank down properly, as it is heilig engaged by the cutters 3Q-35 at the rear of the upper cutter 19, use is made of a compressor spring 25", which is secured to the bar 25 and projects rearward therefrom, the end portion of the spring being so arranged as to lie in the path of the blank and press upon its upper surface to hold it down firmly. In order to hold the blank in proper position, radially, it is desirable to exert pressure upon its inner face as it is moving past the cutters. Such pressure is imparted, in the construction shown, by the presser arm 29. This is pivoted at 29EL to the aforesaid bracket 30.

3l is a spring engaging with one end and tending to press the opposite en d toward the path of the blank. It bears against the inner concave side of the blank at points just beyond the upper cutter, and presses it firmly against the ring holder or the carrier 16.

As above remarked, one of the operations to be accomplished is the cutting and dressing of the inner concave side of the felly blank. This is effected by the devices at 32. The cutter proper is formed of a series of plates or disks superposed one upon another, and each having one or more cutting points formed thereon.` The cutter head as an enf tirety is secured to the upper end of the shaft 32a. This is mounted in bearings at 32, one near the bottom of the machine, and one near the top. These bearings are carried by a frame 33, which can be adjusted rectilineally in and out transversely of the machine, it having slide guides at 32C fitted in guides 32d, secured to or formed on the rear vertical face of the aforesaid frame web or plate 7. At 34 there is an adjusting screw mounted horizontally in the frame work and engaging with the frame 33, and by means of it the cutter head can be moved inward or outward, either to vary the depth of the cut with respect to the fellies of any given radius, or to so position the cutter that fellies of larger radii or smaller radii can be properly dressed. This cutter head 32 and its shaft 32a are driven by the pulley 32e, and the belt 32f, driven from the countershaft 8l.

The final step in the cutting and dressing is, as aforesaid, to produce the curved conformation at intervening sections S0, 80, along the inner or concave faces of the felly elements. The device for this work is indicated as a whole at 35. It is formed with cutters so arranged that their cutting points or edges when rotating generate a form which in cross-section at its edges gives the arc or approximately the arc of a circle. The cutter head is built up of a series of thin plates made on the same plan as are the cutter plates of the head 32, but, considered in series, they increase ir radius from the center transverse plane of the head toward the upper and lower ends. These plates are secured to the upper end of the shaft 35a, which is mounted in bearings 36a, one at the bottom of the machine and one at the top. These bearings are connected together by a frame piece 36, hinged to the aforesaid bodily adjustable frame 33 of the cutter head 32, the mounting being such that the aXis of the hinging for the head 35 is the axis of the shaft 32, This manner of supporting the cutter 35 permits it to be intermittingly moved toward and away from the path of the felly blank, and as a result of such lateral movements of the cutter it produces intermitting cuts upon the wood as the latter passes. The devices shown for accomplishing this swinging of the frame 36, and the cutter 35, comprise a rod 37, pivotally connected at 37el to the frame 36, and means for intermittingly moving this rod inward and outward, in timed relation to the travel of the blank. This rod 37 eX- tends horizontally through a bearing seat in the part 4 of the frame. To it is fitted a trip device 3S, the latter being of the nature of a sleeve fitted to the rod, and having a lateral projection provided with a roller 39. The rod 37 is threaded and adapted to be adjustably fitted to the trip sleeve. At proper times the trip sleeve and the rod 37 are engaged by a cam on the disk 75, which latter will be more fully referred to below. At each revolution of the cam disk the frame 3G will be moved inward around its axis, and the action of the cutter head 35 on the wood will be temporarily stopped. The cutters, however, continue in rotation. The opposite movement of the cutter head and its frame is caused by the devices shown at 40, il and 42. 40 is a chain or cord secured to the arm 4()a at the inner end of the rod 37. This chain or cord passes over a pulley 4l, and is adjustably connected to a lever 42a, which carries an adjustable weight 42. As soon as the cam on the disk ceases its action on the rod 37, the weighted lever instantly restores the cutter head 35 to its operative position in relation to the blank.

The cutter head 35 is actuated from the counter-shaft by means of the belt 350 eng'aging with the pulley at 351 on the shaft 35a. The distance to which the cutter head is moved under the action of the above described devices, is relatively so short that its driving engagement with its belt is not interfered with, notwithstanding its being carried at times from one position to another. This belt 350 is arranged in the same vertical planes as the belt 32f, which drives the shaft of the cutter 32; that is to say, the former travels in a path which lies on the inside of the path of the belt 32? 43 is a shield bracket arranged adjacent to and partially covering and inclosing the cutter heads 32 and 35. It is secured to the top of the table section 10 by means .of a stud pin 43a to which fits a sleeve on the shield. Upon the top face of this bracket shield there are stud pivots 43h and 43". To these are pivoted the roller carriers 44 and 457, they being preferably arms inounted at points intermediate of their ends. The arm 44 has a downwardly-turned extension l,which carries the vertical ,roller 4,5, and at the other end it is connected to the spring I side of the blanks, a cutter for .the concave 4.6. This roller bears against ythe inner, concave, side of the blank as it is passing the

cutters

32 and 35,. The arin 41T also has a downwartl-turned end or journal which supports the roller el-S, the opposite end of `the arm being normally held by a spring 49.

The above described operative parts can be actuated by any suitable power devices. I have shown the following as vmeans for transmitting motion and power: At 51 there is a hollow shaft with pulleys 5l- 51". The former pulley receives power from the belt 52, driven by the counter-shaft. The pulley 5lb is connected by a belt with pulley 54, which is connected to a short hollowT shaft 54", loosely mounted upon a shaft The pulley 54C can be connected to the gear wheel 56 by a clutch 54a. Theel 56 meshes with and drives the wheel 57 on countershaft 58. The latter at the opposite end, by pinion 59, engages the spur wheel ($0. On one side of the wheel 60 is a bevel wheel Gl meshing with the bevel wheel 62, on a vertical shaft (33. At the upper end of this shaft G3 is a spur wheel G6, which engages with an idler wheel 67. The latter' engages with the teeth of the above described feed ring Vl5, and when the parts last described are in action the feed ring` is rotated. The shaft 55 carries a sprocket wheel (5S, which by a chain G9 is connected to the wheel on the shaft 50, the latter receiving its rotation therefrom. The shaft 50 carries a sprocket wheel 7l, which by a chain 72 is connected with the sprocket wheel 73 on shaft 74. The latter extends across the machine and is provided with the cam disk 75 above referred to.
