BALLAST PLOW AND DISTRIBUTOR 3 Sheets-Sheet 6 Filed Jan. 17, 1951 INVENTOR. Royce KA'KJHHW flrromers Patented Jan. 12, 1954 UNITED STATES ATENT OFFIE 3 Claims.

My invention relates to apparatus for regulating and distributing ballast between and around the cross ties of a railroad track and has for an object the provision of such apparatus which shall be effective to evenly regulate and distribute ballast over the road bed, filling all of the cribs between the ties for the full length of the ties whether the ballast is dumped between the rails or adjacent the ends of the ties.

More specifically, my invention contemplates a pair of plow-like spreaders, one of which, hereinafter referred to as the forward plow, is V- shaped and the other of which, hereinafter referred to as the rear plow, is in the form of a truncated V, the plows being mounted rigidly together and for vertical movement on a suitable supporting vehicle, whereby upon forward movement the forward 'plow is operable to distribute and move the ballast outwardly to the ballast shoulder and upon rearward movement the rearmost plow regulates and pulls ballast toward the center of the track but without feeding an excessive amount of ballast to the center of the track as will be explained later.

Another object is to provide a double plow ballast spreader in which the rear plow is provided with hinged ballast blades, and to fix the two plows in such manner that when the forward one is operating upon .the ballast the rear one is inoperative, and which may nevertheless be mounted rigidly together and supported adjustably from the road bed by means of common lifting and holding mechanism.

A further object is to provide a double acting ballast plow and distributor in which the lower working edges of the Wings of the forwardmost plow shall be located above the corresponding lower edges of the hinged blades onthe rearmost plow when such hinged blades are in working position, whereby when the rear plow is operating on the ballast the forward plow is out of contact therewith, providing a more even and effective spreading action and preventing each of the plows from interfering with the operation of the other.

Apparatus illustrating the features of my invention is shown in the accompanying drawings forming a part of this application in which:

Fig. l is a plan view, partly broken away and illustrating a ballast plow and spreader embodying the features of my invention;

Fig. 2 is a side elevational view showing the 'forwardmost plow in operative position and with the hinged blades of the rearmost plow raised to non-working position;

Fig. 3 is a sectional view taken generally along Tline IlI- III of Fig. l, looking at working face of the rearmost plow and showing the hinged blade sections thereof in working position;

Fig. 4 is a fragmentary detail view taken generally along line IV-IV of Fig. 3 and showing the relative disposition of the forward and rear plows with the hinged blades of the rear blow in working position; and

Fig. 5 is a detail sectional view illustrating a fragment of one of the wings of the forwardmost plow and showing a template which may be placed over the rail opening in the plow wings, accommodating the apparatus to rails of different size.

Referring now to the drawings for a better understanding of my invention my improved apparatus comprises a vehicle adapted to run upon the rails I6 and H, the rails being supported on the usual cross ties l2. The vehicle comprises flanged wheels I 3 suitably mounted on axles l4 in turn journaled on depending axle supporting members l6 forming a part of the undercarriage of the vehicle. The vehicle may be provided with a deck in the form of longitudinally extending members I! and the same may be decked over with boards or the like l8 for at least a part of the length of the Vehicle, providing a platform for the operator. The vehicle may also be provided with tow bar connections l9 and 2 I, one at each end, the tow bar connection l9 being herein designated the rear tow bar connection and the tow bar connection 21 being designated the forward tow bar connection. Additionally, there may be provided rail sweepers indicated generally by the numeral 22 positioned as shown in the drawings. These sweepers may comprise a rod 23 carrying at its lower end a strip of flexible material 24 which actually engages the rails l6 and H, thus to remove any ballast from the ball thereof which may be placed thereon while the apparatus is in operation.

Mounted beneath the frame to operate closely to the upper surface of the. cross ties I2 is a V- shaped plow indicated generally by the numeral 26. The plow 26, referred to as the forward plow, may comprise a pair of wings formed of

plates

27 and 28, joined together at the apex 36 by welding or otherwise and extending past the ends of the cross ties. The plates 21 and 28 are inclined rearwardly as shown inthe drawings and may be slightly concave on their forward or working surface. Secured to the lower edges of the plates 2'! and 28' are replaceable scraper blades 29 and 3!, respectively, which proiect slightly below the lower edge of their respective plates, thus to enga e the ballast. The plates 21 and 28 together with their respective scraper blades 29 and in may be notched out as indicated at 32 and 33, re-

spectively, to provide clearance for the rails and to clear the usual fish plates at the joints of the rails and the cross bolts passing through the fish plates and the rails.

At the apex .39 of the forward plow I provide a skid 34 which is in the form of a double upturned shoe-like member and which is adapted to slide upon the cross ties, thus to guide the front or apex of the plow 26 over the ties, preventing it from digging in or jamming against the cross ties.

Similar skids

36 and 31 may be provided intermediate the ends of the wings of the forward plow, preferably just outside of the rails l9 and II. The forward V-shaped plow thus is skid mounted on the

skids

34, 36 and 3'! and is capable of operating very closely to the upper surfaces of the ties.

The rear plow indicated generally by the numeral 38 comprises wings in the form of plates 39 and 4| which are inclined opposite to the inclination of the plates 2'! and 28 and extend past the ends of the cross ties. As shown in the drawings these wings are substantially parallel to the corresponding wings of the forward plow and are disposed at an angle to draw ballast toward the center of the railroad track when the vehicle moves rearwardly. The rear plow 38 is provided at its center with a plate section 42 which is substantially parallel to the cross ties, that is, normal to the center line of the railroad track. The plates 39 and 4| are joined to the plate 42 by welding or otherwise. The rear plow 39 may thus be defined as being of a truncated V-shape, and the advantages of this arrangement will be described in connection with the operation of the apparatus.

Hinged to the plates 39 and 4| are ballast operating blades 43. As best shown in Fig. 4 these blade sections 43 are welded to the rear side of bars or the like 44. These bars are pivotally mounted as at 46 to forwardly extending members 41 welded or otherwise joined to the rear side or non-working of the respective front plates 21 and 28 of the front plow and to the nonworking side of the plates 39 and 4| as the case may be. It will be seen that the upper ends of the members 44 bear against the inner or nonworking sides of the plates 39 and 4|, thus limiting pivotal movement of the blades 43 when they engage the ballast. The truncated section or plate 42 of the plow is provided with a hinged blade section 48 similar in all respects to the sections 43. The plates 39, 4| and 42 are notched out as at adjacent the pivot points 46, thereby to provide clearance for the members 44 when the pivoted blade sections are moved to inoperative position as will now be explained. The hinged sections are so disposed that blades pivot to working position by gravity.

Connected to brackets 52 at intervals along the upper edge of the plates 39 and 4| are lengths of chain 53. The members 44 may be provided with a notch 54 adjacent their lower ends, behind the blades carried thereby. When it is desired to move the blades 43 to inoperative position they are pivoted upwardly as indicated in dotted lines, Fig. 4, and the chain is hooked into the notches 54 as illustrated in dotted lines in Fig. 4. The hinged section 48 may be held in inoperative position without connecting a chain thereto. This is accomplished by folding thi section upwardly prior to upward movement of one of the immediately adjacent sections 43, whereby the section 48 overlies the section 43 and is supported thereby.

iii

As before stated, the front and rear plows are secured rigidly together. This is accomplished not only by the members 41 already described but also by the provision of additional members 56 at the center of the plows and other members 51 near the ends of the wings. Suffice it to say that suitable and suflicient brace members are provideo. so that the two plows are rigidly mounted together. Further, the plows are so fixed relative to each other that the lower edges of the

hinged sections

43 and 48 are about 3 inches lower than the lower edges of the fixed blades 29 and 3| of the forward plow when the hinge sections are in operative position. Likewise, when the sections 43 and 4B are pivoted to the dotted line position shown in Fig. 4, the arrangement and relative mounting of the plows is such that the lower or working edge of the blades 29 and 3| is about 3 inches lower than the lowermost edges of the plates 39, 4| and 42.

Upstanding from the frame of the vehicle are

columns

58 and 59 on which are mounted pulleys 6| and 62. A cable 63 passes over the pulleys and the ends thereof are connected as at 64 to the plow assembly. The cable passes through a hand operated winch indicated generally by the numeral 63 mounted on cross members 61. In similar manner, I provide a hand winch 68 and a cable 69 which is connected at H to the plow assembly adjacent the apex of the forward plow.

Secured to the frame members ll, just forwardly of the point of attachment of the cable 63 to the plow assembly are depending plates 12 and 13. The plates are slotted as indicated at E4 to slidably receive a pin 16 passing through brackets 11 carried by the plow assembly. In similar manner, there is provided at the longitudinal center of the vehicle a single plate 12a disposed substantially over the apex of the forward plow. The member 12a is provided with a slot 14a to receive a pin 16a carried in a bracket Tia secured to the plow assembly. It will be seen from the description just given that the entire plow assembly is capable of vertical movement relative to the vehicle and track and that the pin and slot arrangements guide the plow assembly in its up and down movements.

In some instances it is desirable to vary the effective size of the

slots

32 and 33 in the forward plow. This may be accomplished by the provision of a template 15 having therein a slot 15a of suitable size. This template may be secured to the plates 21 or 28 by means of screws 18, thus decreasing the size of the

slot

32 or 33 as the case may be, and preventing ballast from escaping therethrough.

In connection with the slots it will be understood that the plates 39 and 4| are provided with rail clearing slots 19 and BI, quite similar to the

slots

32 and 33.

From the foregoing the method of constructing and using my improved apparatus may now be explained and understood. With the plows assembled in tandem as shown it willbe apparent that if ballast has been dumped from cars or otherwise near the center of the track, that is between the rails l0 and l, by moving the vehicle forwardly, that is to the right, as shown in Fig. 1, such ballast will be operated upon by the forwardmost plow 26, and distributed over the road bed, filling in all empty cribs the full length of the cross ties. While the apparatus is moving in the forward direction the pivoted

blade sections

43 and 48 of the rearmost plow are held in inoperative position by engaging the chains 53 in and leaves a minimum amount of ballast on top of the ties. Likewise, due to the triangular shape of the forward plow 26, it will be apparent that ballast is moved outwardly of the center line of the track. The inclined blades of the plows exert a lifting and rolling effect on the ballast.

When it is desired to move ballast toward the center of the track the entire plow mechanism is raised upwardly through the medium of the winches and cables and the pivoted

blades

43 and 48 of the rearmost plow 38 are released, causing the members 44 to engage behind the plates 4|, 39 or 42, thus holding the pivoted blade sections in operative position. In this position of the plows the cables support the lower edges of the pivoted blades just above the level of the cross ties. Likewise, in this position the lower edges of the scraper blades 29 and 3| are raised considerably above the level of the ties as illustrated in Fig. 4, thus to be clear of the ballast, and do not interfere with the regulating and distributing operation of the rear plow.

With either of the plows in operation it will be seen that if the blades or any portion thereof strike an obstruction the entire plow mechanism may ride upwardly due to the slots 14 and 14a and sliding pin connections 16 and 16a. In practice, my improved apparatus has been found to be extremely satisfactory for its intended purposes. The truncated rear plow prevents windrowing of the ballast at the center of the track when the apparatus is moved rearwardly. The straight or normally disposed section 48 gives a very even distribution of ballast adjacent the center of the railroad track and eliminates a considerable amount of hand labor over that necessary when using a V-shaped plow for pulling ballast toward the center of the track. In either forward or reverse direction it has been found that my improved apparatus completely fills the spaces between the ties and effects substantiall a finished job with respect to ballasting, very little hand labor beingrequired to complete the ballasting of the track.

With respect to Fig. 5, the provision of the removable templates for reducing the fixed size of the

openings

32 and 33 provides means for accommodating the apparatus to rails of smaller sizes without permitting ballast to spill through the fixed

openings

32 and 33.

While I have shown my invention in but one form, it will be obvious to those skilled in the art that it is not so limited, but is susceptible of various other changes and modifications without departing from the spirit thereof, and I desire, therefore, that only such limitations shall be placed thereupon as are specifically set forth in the appended claims.
