RAIL-GRINDER.

Application led December 7,

f State of Massachusetts, have invented a new and useful Rail-Grinder, of which the following is a specification.

The device forming the subject matter of this application is adapted to. be employed y for grinding the rails of a railroad track, for grinding frogs and for like purposes.

@ne object of the invention is to provide a device of the kind mentioned which maybe secured to the track, thereby avoiding the disadvantages incident to the use of a wheelmounted carriage which moves along the track, it having been found that such a carriage, following the irregularities of the track, causes the grinding wheel to gouge and to operate otherwise, in an improper way. n

Another object of the invention is to provide novel means whereby the grinding wheel Vmay be moved and adjusted with respect to the element which is being ground.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

Vith the above and other objects in view, which will appear as the description proceeds, lthe invention resides in the combination and arrangement of parts and in the details of construction hereinafter described .and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings Figure 1 shows in top plan, a device oon-` structed in accordance with thev invention; Fig. 2 is a side elevation; Fig. 3 is an end elevation wherein parts are broken away; Fig. 4 is a cross section; and Fig. 5 is a fragmental vertical section showing one of the standards, and parts carried thereby.

In carrying out the invention there is provided a mainframe including side bars 1 provided intermediate their ends with depending feet 2 adapted to rest on a rail 3, the feet 2 having lugs 4 which engage the inner edge of the rail. rlhe side bars 1 are supplied at their ends with sockets 5 in which rods 6 are mounted, the rods being Specification of Letters Patent.

.held in place by set screws 7 threaded into the sockets and engaging the'rods. Intermediate their ends, the side bars 1 of the main frame are connected by a V-shaped brace 8 having a flat end 9 provided with an outstanding lip 10 adapted to rest on a rail 11, and provided with a depending ear 12, A set screw le is threaded in the ear 12 and engages the rail 11. f

Standards 15 are adjustable on the side bars 1, longitudinally of the side bars, the standards having elongated feet 16 resting slidably on the side bars, the feet 16 and the side bars being supplied with elongated slots 17, receiving clamp bolts18, the construction being such that the'standards may be adjusted longitudinally of the side bars 1, and be heldin adjusted positions on theside bars.

guides 19, wherein slides 20 reciprocate.

Screws 29 are held for rotation but against longitudinal movement in the standards 15,

the screws 29 being operated by means vof.

cranks 30 or in any other suitable way. The screws 29 are threaded into the slides 20 Aand obviously, when the screws 29 are rotated, the slides 20 will be raised and lowered. The slides 2O include bearings 21'in which are journaled for rocking movement, hollow ,trunnions 22 constituting a part of an auX- iliary frame, the auxiliary frame including I end bars 23 carrying the hollow trunnion'22,

and side bars 24 connecting the end barsQB.

Set screws 25 arethreaded into bearings 21# and engage the hollowfftrunnions22 of the auxiliary frame. Consequently, the au iliary frame may be tilted at any desired angle with respect to the horizontal, and may be held in any position to which it may have been tilted;Vv A lead screw 26V is `iournaled for rotation in the hollow trunnions 22 and is held against longitudinal movement by means of collars 27', coacting with the outer ends of the bearings 21, the `lead screw being operated by means of a crank 28.

rlhe numeral 31 marks a carriage having lugs 32 mounted to slide on the side bars 241 of the auxiliary frame. The carriage 31 has a depending lug 33, into which the lead screw 26 is threaded. Hangers 34 depend from the carriage 31, a shaft 35 being journaled in the hangers. is fixed to the shaft 35, for rotation therewith. The shaft S5 is supplied with a pul- A grinding wheel 36l A ley ,about which is trained a belt 38, enf gaging a pulley 39 on the shaft l0 ol a motor Allk mounted on thelcarriage 31. YThe motor 41, preferably is driven electrically. n

In practical Operation, the main frame is mounted on the rails 3k and 11 as shown Yin Fig. '-3, the lng 4 engaging the" rail 3, the lip K .10 resting on the rail 11, and the set screiv 14 being advanced, so. to bea-r against the inner edge of therail 11." In `tlnis Way, the main tra-ine islieldsecu-rely on the rails. By loosening the clamp bolts 18, the standards 1f`5 may be shifted longitudinally of the side bars 1 of the main frame so as to position the grinding Wheel 36 above the rail 3 which is to be ground, ftliefclamp bolts'18 being then tightened up, tohold the standards 15 in the' positions to Whicli they haveV been ad- 'justedirv The 4screws 29 may be rotated, and,

because the said screws are threaded into theV slides 2020i the auxiliary frame, the auxil iary frame, rtogether with the grinding Wheel 36V may V4be raisedand lowered thereby adf Vjnsting ithe lpositionof the grinding Wheel with respect to the yrail 3 which is tobe ground. Further, by loosening. the set screws 25, the hollow' trunnions 22 of, the auxiliary trannie may be permittedto rocl in the Y bearings '21 of itlie slides 20, in` this Way., tflie auxiliary traine may be positioned fat different angles with Vrespect to the liorizontal, the positie-not the Working face of tliegrinding vvneel-36 with respect to the :rail being altered accordingly. The auxiliary framemay belie'ldin yany position to which it may have been tilted by'tiglitening up the' setxscreWs-:25- After the machine llas 'been' jiis ,ustedV :and Y placed aoresaidgtlie lead .scre'iiv 26 is notatednby means of thec'ranfk '23, '.40

lthe .carriage being moved longitudinally of: the side bars V24,01c the .auxiliary frame, and the grinding .Wheel-36 sbeing made to traversethe rail which is to begrotind Rowherein a carriage moves bodily along tlie -rails of the track, the Wheels of the carriage necessarily iolloiv the vertical irregularities of the rails and the grinding AWheel participates in the vertical movement, a gouging of the rail resulting. Since the structure forming the Subj ect matter of this application includes a lixed frame, it is clear that rthe dis-Y advantages arising ont of the use of a Wheelniounted carriage will `be avoided.
