Figure 9 illustrates part of the guarding mechanism 'for the working head; and

Figure l is a. perspective view of one of the guard elements.

Like parts are indicated by like symbols throughout the specilication and drawings.

Referring 'lo-r example to Figure l, A generally indicates a railroad tie, upon which are mounted the rails A1 and A2. Figure 1 indicates the device in position to be conveyed along a track in which both rails are in position, The rail A1 is `the rail upon which the device is supported when in position for operation, as shown 'for example in Figure 2.

Referring to the frame structure as shown ttor example in Figures l and 3 I employ a trame or body generally indicated as B,

which overlies the track A1. It may include the longitudinal structural elements, shown as the parallel angles B1 B1. The angles B1 may be connected at their ends, as by the plates B2. v Mounted adjacent each end of the frame Bis a wheel Bs the axles of which B4 rotate in bearings B5 associated with the structural elements B1. verse straps each pair being connected by a cross piece B7 upwardly projecting from which is a pin B8 adapted to receive spare cutter heads and the like. The upper end of the pin is screwthreaded as at B9 to receive any suitable locking member B10. ,Y

Extending transversely across the frame B, and ybeing of such length as to bridge the rails A1 and A2, is the frame structure generally indicated as C which includes thev channel members C1 which are bent to converge as at C2 and which terminate in the parallel portions C3 separated by a lesser distance than the original portions C1. The said channel members may be connected by any suitable connecting elements, bars or the like, generally indicated as C4. v Mounted upon the frame C, at apoint somewhat to the right of the rail A1, referring to the position in which the parts are shown in Figuresv l and 3 is any suitable motive means or engine generallyindicated as D, which may include the driving pulley D1 about which passes the belt D2. The pulley is shown, as in Figures l and 2, as passing beneath the idler-.D adjustable upon the arm or bracket D4 upwardly projecting from the frame. D generally indicatesa bearing sleeve having the associated web structures D, the sleeve and its webs being positioned between the parallel structure members C3 and being adjustable in relation to said members. vAs anexample of a practical adjustment I indicate the inclined or arcuate slots D7 through which pass the locking members D8, the slots being shown in Figure 1 as formed in the members C3. Rotatable in the sleeve D5 is the cutter shaft D9 upon the lower end of which is mounted any suitable cutter head D the details of which do not of themselves form part of thepresent invention. It will be understood that there B6 indicate transr the working end, upon a plura is a central spacing` member or abutn'icnt D11 the lower face of which in the general plane of the cutting edges of the individual radial cutters D11. D1 is a pulley associated with the sha-ft D, about which passes 'the belt D2, Whereby rotation oi tlie pulley D1, when the engine D being` driven, rotates the shaft D1 and the cutter head mounted thereupon. Preferably the slots D7 are so formed or set at such an angie, or With such a radius, that the sleeve D5, and the shaft D, are rotated about a center which is positioned at or adjacent the center of the bottom oi the spacing member or abutment member D11.` In order to control or to pe mit the aec irate adjustment of the incl-.in ation 4 t the euttingig' anis 1 l l MGS of the cutter head l provide the g5 Cuated scale D14 aligned iv th the heb D15 supported upon the chain or cord 15, and adapte l t i depend directly vertically in response to grav ity. In order to aid in positioning` or arbusting the cutter head and its sleeve l provide an abutment D17 upon the tran members C5 and an opposed a; tin screw or screwthreaded element D1S which penetrates the boss D19 and may be loeled at any desired adjustment, as by the loch nut D20.

cress pieceFI '12.11, where ample employ the guards G2 G2, diametrically opposed, which are suspended by flexible supports G3 'from the handle G or from the structural members'C5. In order to bridge Athe space between the ends of the guards G2 G2 I provide the guard elements shown in Figures 9 and 10 as G1V which may be supported by the hooks G5, connected by the cross supports G5. It will be seen, as in Figure 9, that the ends G7 of these hooks may' penetrate beneath the structural members C2 remote from each guard, whereas the raised intermediate portion G5 passes over the structural member C5 nearest the guard. The guards G1 are relatively flexible and may be provided with vertical slits G2, or may be otherwise formed to permit them to override obstacles or to permit obstacles to pass therethrough. This is necessary since, in adzing ties, pegs may be driven into the top of the tie, to lill old spike holes and the like and these pegs, until they have been driven down or trimmed olf, project upwardly from the face of the tie.

W hen the device is tilted by gravity into operating position, and is supported only on the track A1, the flanges of the wheels B3 prevent movement of the device toward the right, referring to theposition as shown in Figure 2. In order to hold the device on the rail A1 and to preventV it from moving, say, to the left, I provide means for engaging the side of the rail A1. I illustrate for eX- ample the plates H at each end of the frame B. As a matter ol convenience these are shown as conforming in shape to the transverse connecting elements B2. To each such plate is pivoted a pair of arms H1. Upon the lower end of each arm is rotatably mounted a roller H2. each plate H is provided with arcuate portions H3 provided with adjusting apertures H4 into which may penetrate the adjustable locking pin H5, whereby each arm H1, with its roller, may be set at any desired angle in relation to the plate H. The spring H6 tends to keep the locking pin H5 in locking position, it being compressed between the abutment element H7 mounted upon the arm H1 and the washer H8 mounted upon the pin H5. H5 is a block or guide element which may be secured to the plate B2, as by the bolts I 10. his block passes through or is positioned in the slot H11. The block may be provided with an enlarged portion I 12, or with a-n additional block or abutment of greater width than the slot H11, whereby the movement of the plate H in relation to the plate B2 is limited to a vertical excursion of predetermined length. H13 is any suitable spacing element or elements for the lower portion of the plate H. H11 is a hook upon each arm H1, adapted to surround the arcuate lower edge of the plate i H to prevent loutward movement of the arm.

The lower edge ot' In order to litt the plate H in relation Yto the plate B2 I provide the hooked handle pin H15 the lower shank oli which is rotatable in the abutment H15 secured to the plate H, and preferably the same thickness as the spacing abutments H15.l Associated with the handle pin H15 are the transverse projections H17 H15. H15 indicates an aperture in the plate H to permit rotation of the member I 15 and its lateral projections or. hooks H17 H12. When the plate H is in the lowermost position, as shown in Figure 5 neither hook I- 17 or H13 is ei'igaged. rl`he hook H17 extends outwardly through the aperture H15 but the plate H is supported by the engagement of the upper edge o'l the aperture H11 with the 'top or the block H2. lit/'hen the device is supported only on the rail lthe pla-te H is in lowest position, with one oli the rollers H2 opposed to each side of the rail A1. However, when the device is supported on beth rollers, or when it is lbeing moved along a single rolle pasta. switch or crossing or the like, it is necessary to lift the plate H, in order that the rollers H2 may be above. the level of the top of the rails. A maximum litt, as shown in Figure 8, and in Figure 7, is etlected when the hook H17 is hooked over the top orn the plate B2, the upper hook H15 being then in idle position. For an intermediate adjustment, as shown in dotted line in Figure G, in case it is desired to lift the roller somewhat to clear an adjacent obstruction but still not to lift them clear oit the rail, I may lengage the hoolrI-I1S with the top of the plate B2. yhis is the position shown in dotted line in Figure 6.

In order to protect this mechanism from damage in case the machine comes in contact with another vehicle or with obstructions, l provide the guard J, shown in full line in Figure il, and in dotted line in `Figure 6. This guard J includes the forwardly projecting guard portion proper J1 the top and bottom ol which are recurved or bent to connect `to the supporting portion J7, which supporting rportion may be secured to the enlarged portion H12 of the block H2 as by bolts H10 as illustrated in dotted lines in Figure 6. I y

In order to move the adzing machine along` a track I provide means lfor hitching said machine to any suitable power di' en vchicle'. For example I may employ the coupling bar K, one end of which may be placed upon'either angle bar E2 olf the frame E1 beneath the fork offset bar H1. The fork K1, angle bar F11 and either end of the coupling bar l may be apertured to receive the 'locking pin K2. It will understood from the drawings that a plurality oi adaing machines may be hitched together for transportation.

` It will be realized that whereas I have described and shown a practical and operative device, nevertheless many changes might be made in the size, shape, number and disposition ot parts without departing from the spirit et my invention. I therefore wish my description and drawings to be taken as in a broad sense illustrative and diagrammatic rather than as limiting me'to my specific showing.

The use and operation of my invention are as Jfollows:

My device is shown as applied to the adzing of the top surfaces oit ties to receive the rails of a railway track. however, that, although this is a preferred use ot my device, my invention is applicable, also, jor other purposes, and, in fact, may be employed tor practically any operation in which a tool has to be used upon or directed against a railway tie or a rail, or any other object .vithin reach oit' the rail upon which the device is mounted.

llowever, considering theapplication of my invention to an adzing machine, I illustrate a frame long enough to extend across both rails oi" the usual railway track. llflounted upon this frame is a working head, the head shown being particularly adaptable for adzing et the top of a tie. Assuming that th's head is to work upon the top ot a tie at a point troni which the rail has been removd, I provide means, viz: the wheels E, which have the multiple tunction ot aiding in the support of the device when i is conveyed along a railway track, and et holding` the cutter head out ot' contact with the rail when the device is being so conveyed, and et acting as a counterweioht to tilt the .trame upwardly away 'trom the tie, when it is moved to the lull line position in which it is shown in Figure In the torni et the device herein shown I illustrate as power plant an internal combustion engine. This engine is placed adjacent the rail engaged by the wheels l5, viz: the wheels which are in constant engnigeinent with a rail. T he wheels E are preterahly et such weight as to hold the end ot the trame down in the position in which it is shown in Figure l, When it is moved to its opposite position, the lull line position et Figure l, it cooperates with the weight et the engine in tilting the opposite end ot the 'traine upwardly into inoperative position. When it is so tilted the operator can thrust the cutter head downwardly against the rail, the parts and weights being so proportioned that an operator can easily thrust the cutter head downwardly, although when his manual 'thrust is released the weight ot the counterweight, or of the counterweight and engine, immediately rotates the cutter head upwardly away 'from the tie.

In a device ot this type, in which during operation the trame is mounted on a single rail, it .is necessary to provide means 'for held- I wish it undestood,-

ing the wheels B3 in position en the rail. As an example et such means I illustrate the rail engaging rollers H2, which are shown, as in Figure l, adjustable toward and away, from the rail.. It is important that there should be such adjustment, since the size, height and width oi' rail may vary and the cutters need be adjusted. [in increase in the height of the rail ali'ects the angular relation ot' the cutting plane to the tie. A/lny adjustment necessary to care for height or width olf rail and location or inclination of the cutting plane may be effected by the adjustment et the rollers, together with the adjustment et the axis ot the cutter in r lation to the 'trame or, more properly stated, in relation to the plane ot the tie.

For adjusting the cutter, and tor setting it at any desired angle, I provide the gravital adjusting means shown in lEigure 2, namely the bob D15 suspended upon the flexible support D10 and aligned with the calibrated gauge D14.

In order to provide adequate and complete prot cting or guarding means tor preventing radial discharge et chips, splinters, hits el s cel and the like, I provide the flexibly mounted guards G2 and the flexible guards G4. I do not wish to be limited except so tar as I limit myselt in the claims, to any precise gum-ding n'xeans, but I tiud the means shown to be effective.

In moving the adzing machine along a track or rail it frequently is necessary to litt the rollers H2. A slight lifting movement may loe sullicient to clear abutting elements which are somewhat lower than the top et' the rail. In passing over switches and the like it may be necessary to lift the rollers H2 s high as or above the level ot the top et the rail. l therefore provide the double adjustment or li'tting support elsewhere described, and shown in considerable detail in Figures 5, G, 7 and S. In Figure 5 the rollers II2 are shown in their lowest adjustment. In Figure 7 the rollers, and their supporting plate Irl are shown raised to the highest poss'ble position. Figure 6 indicates, in the dotted line position. an inter mediate adjustment. In-order to prevent damafi to this adjusting niccl'ianism, as when the adzing machine is abutting against another machine or a conveying means s h as a hand car locomotive or the like, l provide the guards J.

In operating these devices it will be understood that a number o't them may be simultaneously employed and I {ind a particularly useful and efficient method ot adzing ties to be to run a gang ot these machinesialong a track or rail and across a series ot ties, any retrograde movement of any individual adzing machine being thus avoided, the entire gang of adzing machines being constantly moved in the like direction. Assuming that five are used, each tie will successively be subjected to five adzing operations. Where a single machine is used the operator in practice finds it necessary to move the adzing inachine back and forth several times across the top of a single tie.

`Whereas I have described my invention as applied to an adzing machine it will be understood that with ak change in the cutting or working element actually used my device may be employed for working upon the road bed or upon the rail. For example it may be used to grind off rail joints and it may be used to drill holes in rails, rail flanges, ties and the like. Except so far as I speciiically limit myself in the claims I `wish my claims to be understood as of sufficient scope to covei1 the structure herein disclosed, or its equivalent,

regardless of the specific use to which it may be put.
