SANDING DEVICE FOR CARS.

SPECIFICATION forming part of Letters Patent No. 510,258, dated December 5, 1893.

Application filed March 20, 1893.

To a/ZZ whom it may concern:

Be it known that I, HERBERT H. HENNEGIN, of the city of St. Louis and State ofMi'ssouri, have invented certain new and useful Improvements in Sand Boxes for Cars, te., of which the followingis a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.-

My invention relates to improvements in sand attachments for cars and consists in the novel arrangement and combination of parts, as will be more fully hereinafter described and designated in the claims.

The object of my invention is to construct an improved device of this kind embodying many new and useful attachments which combine to perfect this' class of manufactures.

In the drawings: Figure 1 is a detail side .elevation of my complete invention as applied to a car, parts of said car being broken away and sectioned. Fig. 2 is a side enlarged detail sectional elevation of my invention applied to a car and showing the alternate -position of parts in dotted lines. Fig. 3 is a transverse sectional view taken through a line A-A in Fig. 2. Fig. 4 is artransverse sectional view taken on a line B-B in Fig. 2. Fig. 5 is a detail elevation of the toggle levers made use of. Fig. 6 is a side elevation of the same lever. Fig. 7 is a detail elevation of a bell-crank lever made use of in carrying out my invention. Fig. 8 is a detail side elevation of the same. Fig. 9 is a top plan view of said lever. Fig. l0 is a vertical detail enlarged sectional view showing the ball bearing. Fig. 11 is a detail top plan view ofone of the attachments. Fig. 12 is a detail per- Spective view of a portion of the rack.

Referring to the drawings: My complete invention is constructed with its larger portion under the iioor 1 of the car and is adapted p to be operated by means provided,and which Serial No. l466.757. (No model.)

side of said cylinder 4 and with top and bot- 'tom walls 12 also connecting with the side walls of the cylinder 4. The walls 11 have vertical outwardly projecting curvilinear extensions 13 which definethe outline of a subcylinder 14 which consists of an upwardly projecting circular wall from the bott-om` wall 12 of said opening 10. The sub cylinder 14 is adapted for the guidance and location of the reciprocatory device about to be described. This device consists of a vertical shaft 15 which isprovided upon its lower end with a collar 16, which is provided with an annular semi-circular depression 17. About midway of the length of said shaft is located a collar 18 similar in construction to the collar 16. A short distance above the collar 18 is located a substantially conical shaped downwardly canted circular wall19 which has a depending circular wall 20 of such a diameter that it will it over the upwardly projecting -sub cylinder Wall 14. Projecting upwardly from the conical shaped portion 19 is a spiral blade 21 which projects upwardly through an opening 22 in the plate 7, and the opening 23 in the door 1 of the car. Secured near the lower end of said spiral blade is a collar 24 having a projecting curved arm 25 which is'adapted to agitate the sand in the hopper 3 when the spiral is revolved by a means hereinafter described. A similar device is also located near the upper end of said blade 21and for the samepurpose. i

As particularly shown in Fig. lOit will be seen that a number of friction ballsY 26 are located in the annular semi circular depressions 17 and are adapted to facilitate a downward and circular movement which the shaft 15 and its accompanying parts had. It will thus be seen that the sub cylinder walls 14 form a bearing for the movement of said shaft 15 and its parts and the object of makinguse of the balls 26 is to guarantee a certain movement of the parts in both directions. In this instance I have shown a curved pipe 27 secured to the lower projecting end 6 of the eyl- IOO inder 4, said pipe 27 leading to a point in front ofthe surface of the roller 28 and held in position by a brace 29 secured to the truck frame 30.

Midway upon the length of the shaft between the two collars 16 is mounted a gear pinion 31 adapted to be engaged by the teeth 32 in a rack bar 33.

Projecting from the cylinder 4 under thel flange 9 are two webs 34, one projecting rearwardly from the same and the other in front of the same. Pivotally connected to the rear web 34 is a toggle lever 35, the lower end of which is pivoted over the rear end of the rack bar 33. Pivoted to the front web 34 is a triangular casting 36, the same having three pivotal connections and therefore forming a bell crank lever. The lower arm 37 of said bell crank lever 36 is pivoted near the forward end of a rack bar 33, and with the lever 35 serves to hold said rack bar in continuous engagement with the teeth upon the pinion 31.

The horizontal upper arm 38 of the bell crank lever 36 is pivotally mounted in a slot 39, extending almost through the entire length of a weight 40, which is adapted to compel the return of the bars to their normal position after an operation.

Connected to the forward end of a rack bar 33 is a connecting rod 41, the free end of which is mounted between two ears 42 upon the lower end of a rocking lever 43. Said rocking lever 43 is pivotally mounted between two downwardly projecting castings 44 secured to the under side of the platform 2, said lever being somewhat in the shape of a capital letter T.

The form of the upper portion of the rocking-lever 43 is somewhat peculiar, as it provides a curvilinear depression 45 in which is adapted to operate a foot-pin 46 which is located in an opening in the door and in a projecting portion 47 downwardly from the plate of the casting 44. In the forward end of the upper portion of said lever 43 is provided a curvilinear depression 48 in which is located a pin 49 which is located in a small casting 50 and projects upwardly through the floor, both of said pins 46 and 49 being provided with enlargements 51 upon their upper ends for engagement by the foot.

The operation of my invention is substantially as follows: The parts when in position ready for the operation assume the position as shown in Fig. 2 with the rear end of the rocking lever 43 at its upwardlimit, consequently determining the upward position of the pin 46, the rack bar 30 is at its normal backward limit and the weight 40 is consequently down at its lowest plane, the cap 19 being up and engaging the opening 22, closing the same against the passage of sand. The rack bar 33 is provided along its upper and lower edges and above the teeth with flanges 52 which are adapted `to prevent the disengagement of the teeth 32 upon the rack-bar from the teeth `upon the pinion 3l. The pushing down upon the pin 4G rocks the lever 43 forward, consequently bringing the connecting rod 41 outwardly, thus drawing the rack bar 33 forward and downward. rIhe engagement of the 'flanges 52 upon said rack-bar with the pinion 3l also brings down the shaft l5 and all of its accompanying parts by reason of the fixed engagement of said pinion 3l upon said shaft. This operation brings the cap 19 downwardly from engagement with the edge of the opening 22 and allows the passage of the sand from the hopper 3 down through the cylinder 4 and out through the leading pipes as shown. The forward and downward movement of the rack bar 33 revolves said shaft at the same time that it gives the same a downward movement, and causes the spiral blade 21 together with the arms 25 to agitate the sand and `cause the same to flow downwardly. Rapid repetitions of the downward movement bythe foot upon the pin 46 causes the repeated revolutions and downward movements ofthe shaft and its various accompanying parts, therebycausing a ready and continuous flow of the sand to perfect the function of the device. This function, although not above lstated is well known, as 'it consists in the sprinkling of sand or other material of alike nature upon an icy or wet track to facilitate the gripping of the rollers thereon for the passage of the car. In case the weight 40 were not sufficient to cause the quick return ofthe rack to its normal position I have provided an ear 49 engagingin the depression 4S and which when Apressed down causes the rear end of the rocking lever 43 to assumeits normal position. Theconnecting rod 41 `passes through the said slot 49 in the said weight 40 as particularly shown in Fig. 2. The return of the parts to their normal position could be equally as well governed by the use of a spring instead of a weight, without in any way materially affecting the idea andthe scope of my invention.

All of the parts are made in a durable manner of proper metal, so as to withstand the liability to disablement and breakage.

Having fully described my invention, what I claim is 1. An improved sanding attachment for cars having a sand releasing device adapted to be vertically reciprocated and simultatan eously revolved, substantially as set forth.

2. An improved sanding attachment for cars having a sand releasing device vertically reciprocatory simultaneously revoluble, and means for causing the return of said device to cut off the passage of the sand froml the hopper, substantially as set forth.

3. An improved sanding attachment for cars having a device for releasing sand from ahopp'cr, means forconveyingthe same to the truck in front of the 'surface of the vrollers, said sand releasing device vertically reciprocatory, simultaneously revpluble, and adapted to be operated from the platform of the car, substantially as set forth.

4. An improved sanding attachment for IOO IIO

cars having a cylinder located under the car body, a hopper in connection therewith, a passage leading from said hopper to said cylinder, a vertically reciprocatory and simultaneously revoluble means for normally closing said passage, and said means adapted to be operated to open said passage by connection with a device located under the platform of the car substantially as set forth.

5. An improved sanding attachment for cars having a vertical shaft reciprocatory and revoluble within a sub-cylinder, said shaft provided with ball bearings in said cylinder,

a cut off cap upon said cylinder to close the passage of sand from the hopper, an opening located on said shaft and adapted to be engaged by a rack bar operative from under the platform of the car, and means for returning the parts to their normal position, sub stantially asset forth.

In testimony Whereof'I affix my signature in presence of two witnesses.
