LOADING DEVICE. I
Pa tented June 8, 1920.
To all whom it mag concern I Be it known that I, HENRY W. NAGEL, a
citizen of Germany, residing at Chicago, in
the county of Cook,.State of Illinois, have invented certain new and useful Improvements in Loading Devices, of which the following is a specification.
The present invention relates generally to loading devices for handling materials of various kinds and has to do more particularly with devices where the material is conveyed to the delivery point, or points, by
- by the movement of one of the chutes. The
different features and advantages of the inventionwi'll be more fully understood upon reference to the following detailed description taken in connection with the accom panying drawing while the scope of the invention will be particularly pointed out in the appended claims.
In said drawing, Figure 1 is a vertical section of a portion of a coaling station embodying the features of the present invention; Fig. 2 is a side elevation of the princi-. pal parts shown in Fig. 1; Fig. 3 is a perspective view of the drum which receives and delivers the charges ofcoal; and Fig.' 4 is a partial sectional View similar to Fig. 1 of a modified form of the invention. Throughout these Views like characters refer to like parts.
Referring to the drawing in detail, A de I ignates the coal pocket, B the drum, G the for driving the drum.
drum frame, I) the double outlet spout, E and F the chutes, and G' an electric motor The coal pocket A may be built according to any preferred construction. In the present instance itswalls are composed of reinforced concrete. The pocket is located at a suflicient elevation to allow 'a train .to readi y pass beneath the chu es E and F 'C have curved walls which are concentric when they are in their elevated positions. The maxlmum cross section of such a train is Indicated by the dotted outlines 10. The pocket A may be supported in any desired way, as for instance, by piers one of which 1s indlcated at 11. The particular way of constructing and supporting the pocket forms no part of my invention and need not be described in further detail. The bottom of the pocket is provided with an outlet 12 through which the coal is adapted to pass by gravitg. I
The drum is located directly beneath the opening 12 in the frame C. This frame" consists of sides 13, 14, and ends 15, 16, These parts may be castings or they may be built up of sheet steel and angles. In the present instance the sides and ends have flanges 17 which fit against the under side 'of'the pocket A around the opening 12.
Threaded rods 18 are positioned in the concrete ofthe pocket A during the construction of the pocket and when the frame (J is put in place these rods extend through openings in the flanges 17 and by means of nuts, threaded on the rods and bearing .against the flanges, the sides and ends of the frame C are securely fastened to the pocket A. The sides 13 and 14 of the frame with the axisof the drum. When the druni is in place in the casing there is a slight I clearance between these sides and the cylindrical wall oftlie'drum. The ends 15 and 16 of the frame C have enlarged portions which are bored out to form bearings 19 and 20 for the stud shafts 21' and 22, respectively, of the drum B. The end 16 is also provided with an extension 23 which forms a support for the motor G. -The shaft of the latter is geared to the stud shaft 22 of the drum through suitable gearing including the pinion 24, gear wheel 25 and worm gearing within the casing 26:-
The drum B is preferably constructed of sheet steel having ends 27 and 28 joined by a cylindrical wall 29. One side of the cyl-.
inder thus formed is cut away so as to provide an opening of substantially the samecross sectional area as the outlet 12 of the pocket A. The stud shafts 21 and 22 extend outward from the ends 27 and 28 respectively. The interior of these ends is in each instance reinforced by a member 30 which serves to strengthen the ends at the joints where the stud shafts are attached.
If desired these reinforcing members may be integral with the stud shafts.
. terior of the cylindrical wall 29 is reinforced by angle irons 31. From the description thus far it will be seen that when the drum I provided with a toothed casting 33 upon which are located ribs 34 which are positioned so as to fit against the pro ect1ng portions of the angles 31. By riveting the ribs to the angles the casting 33 is firmly held in place. Its teeth 35 are provided so as to more readily cut through the coal. When the parts are in operation the drum rotates in the direction indicated by the arrow in Fig. 1.
' The sides 13 and 14 of the frame C are provided at their lower edges with flanges 36. These flanges provide means for connecting like flanges 37 upon the upper end of the spout D. .This spout may be formed of cast metal or may be built up of structural steel as desired. It is provided with an upper portion 38 which has practically the same cross sectional area as the open ing in the drum. This portion communicates with two outlets 39 and 40. A gate 41 is (pivoted midway between the outlets 39' an and in one position it closes the outlet 39 and in its alternate position it closes the outlet 40.
The chutes E and F are respectively pivoted to lugs 42 and 43 extending downward from the spout D. Each chute consists of side walls 44, a bottom 45 and an end 46. The bottom 45 does not extend as far as the sides 44. and consequently leaves an opening 47 through which the coal passes. The weight of the chutes is in each instance counterbalanced. In the. case of chute F the counter-weight 48 is connected to a cord 49 which passes over a pulley 50 in a bracket 51 secured to one side of the pocket A. The opposite end of the cord is secured to the end 46 of the chute F as clearly illustrated. An angle 52 secured to the side of the structure serves as a stop for the countar-weight 48. In the case of chute E a cord 53 is similarly secured to the end of the chute and passes over a pulley 54 in a I bracket 55 upon the inclined side of the pocket. This cord may also be provided with a counter-weight similar to the Weight 48, but the arrangement of the cord and weight will be obvious and need not be further referred to.
The gate 41 is operated in response to movements of the chute F. This is brought about by securing a gear segment 56 to the The inchute and a cooperating gear segment 57 to the gate. The gear segment 57 and the gate.
are preferably secured to a common pivot rod 58. With this arrangement it will be seen that when chute F is in its lowermost position, gate 41 is in position to close the outlet 39. On the other hand,'when chute F is in its uppermost position, gate 41 will closeoutlet 40. a
In the normal condition of the parts the chutes E and F areelevated, the motor G is at rest and the pocket A is provided with a supply of coal. When itis desired to use the device, the locomotive is moved into position so as to bring the tender beneath one of the chutes. The arrangement is such that locomotives on two different tracks may be loaded from the'same pocket. If it be assumed that the locomotive is positioned so as to be supplied through chute E, then all that the attendant has to do is to lower the end of. the chute from the full line position to the dotted lineposition of Fig. 1, and
start the motor G. For the latter purpose a swltch convenient to the chute may be provlded. As soon as the motor starts, the
drum B begins. to rotate and coal which has,
passed from the pocket into the drum is delivered through the opening of the drum into the spout D. It will be noted that at this time the chute F is in its elevated positionand the gate 41 is in its dotted line position. The coal delivered into the spout will then pass out'through outlet 39 into the chute E and thence into the locomotive ten der. Upon each revolution of the drum a definite amount of coal is taken from the pocket and discharged into the tender. As 7 the drum rotates the teeth 35 crush, the lumps of coal as they cut through it and insure a full charge for each revolution. In
acommercial installation, the drum would ordmarlly make, four revolutions a 11111111136 and the drumwould hold about one ton, i
thus making a delivery of.- approximately four tons per minute to the locomotive.
If it be assumed that the locomotive is on the track? which would bring it under chute F, then the chute E would be in its'elevated position and as soon as chute F was lowered, gate 41 would be moved into the full line position of Fig. 1. Then, as soon as the motor was started, coal would be delivered through outlet 40 into chuteF and thence to the locomotive.
In some instances the coal may include many, large and hard lumps and in such cases it may be preferable to employ astructure which does not require that the advancing edge of the drum cut through the coal on ,a definite and fixed line. To meet such a case I provide the structure of Fig. 4 wherein the drum B receives the coal at a slightly different angle than does the drum B in the structure of the previous figures.
so. as to provide a slight'clearancewhile on the other side a considerable space-is leftfor the passage of coal which may not enter the drum but be carried around upon its outer surface. The outlet spout D also differs in shape from the outlet spout D but the arrangement of the chutes E and F and the gearing for operating the gate 41 are the same. The drum B is the same'in construction as the drum B, except that the teeth for cutting through the coal are omitted. In other words, it is the same except that the casting 33 is omitted. In this case the drum is preferably rotated in the direction indicated by the arrow in Fig. 4 which is 0]};
posite to the direction ,in which the drum is rotated. The gearing for driving the drum B will therefore require an additional gear wheel in the train so as .to ive this reversed direction of rotation. he frame C is secured to the coal pocket A inany suitable way and is located at its outlet 12 so as to receive the coalagainst the inclined face 60 of the frame. As the coal engages this face it moves downward toward the left as viewed in Fig. 4,'into the drum B whenever the latter has its open side in position to receive the coal. As the drum rotates the coal within the drum is conveyed around and separated from that upon and adjacent to the inclined face 60. If large lumps of coal are. encountered at a time when the drum is practically filled, they will be pressed upward and kept out of the drum. As the drum rotates some of these lumps may be carried on the outer surface of the drum until they have advanced far enough to drop into the passage 61. In such a case they will be mixed with the coal discharged from the drum B atthe time when the open side of the drum reaches a point above the outlet spout D. If the lumps are too large to enter the passage 61 they will pass out through the opening 62 and fall to the ground or to any receptacle that may be. provided, to receive them. Ordinarily but few lumps will be encountered which will not enter the passage 61. At the same time that,the large lumps are being carried around upon the outer surface of the drum B,.small pieces of coal may also be carried around and they will enter the passage 61 and finally drop.
ployed. With this modified construction the coal is not measured with the same accuracy as with the structure employing drum B but the measurements will ordinarily be sufficiently accurate because of the small amount of coalwhich will be carried around on the outer surface of the drum. When the coal has been delivered to the spout D it will be deposited in the chutes E and F according to the position of gate 41 controlled.
by the gear segments 56 and 57 just as heretofore described in connection with the structure of Fig.1. In this modified structure I have shown the chutes E and F somewhat smaller in proportion to the other parts than in Fig. 1 but these; may obviously be of any desired'size according to the intended capacity of the plant.
Although the inventionhas been described with reference to .a construction for handling coal, it is obvious that many of its features might be employed in handling other materials and in feeding them to cars or other 'receptacles. I, therefore, do not wish to be limited to the particular application herein'..i1lu strated but aim to cover the invention in its broad aspect in the appended claims. It will also be'obvious that in carrying out my invention certain modifications and alterations may be made in the details of construction and arrangement of parts without departing from the spirit and scope of my invention.
