FRED R. TAISEY, OF INDIANAPOLIS, INDIANA, ASSIGNOR TO THE TAISEY PNEUMATIC SERVICE COMPANY, OF INDIANAPOLIS, INDIANA, A COR- PORATION OF INDIANA.
DESPATCH-TUBE.
SPECIFICATION forming part f Letters Patent No. 690,67 5, dated January 7, 1902. AApplication iiled May 9, 1901. Serial No. 59.520. (No model.)
To all whom, it may concern: l
Be it known that I, FRED'R. TAI'SEY,` of Indianapolis, county of Marion, and State of Indiana, have invented a certain new and useful Despatch-Tube; and I do hereby declare that the following is a full, clear,A and exact description thereof, reference being had to the accompanying drawings, in which like iigures refer to like parts.
This invention relates to the construction of despatch-tubes to diminish the friction of independent carrier-boxes against the wall of the tube, andespecially in the curves of the tube. This object is attained by providing two or more internal longitudinally-extending antifriction-ribs in the portion of the tube with which an independent carrier-box will come in contact during its passage'. In a horizontal straight tube such ribs are in the lower portion thereof, as the box rides upon them by gravity. At a bend the ribs are on the outside of the curve, as the centrifugal force of the box throws it against the outside wall of the curved tube.
The nature of this invention will be understood from the accompanying drawings and the following description and claims.
In the drawings, Figure 1 is a plan of a straight and a curved portion of pneumatic tubing with parts broken away and parts in section. Fig. 2 is a section in perspective on the line AA'of Fig. l. Fig. 3 is a section on the line B B of Fig. l. Fig. is a section on the line C C of Fig. l. Fig. 5 is across-section of a straight tube when vertical.V
In detail, l represents a straight portion of a pneumatic tube, and 2 a curved portion. The curved portion is formed of two longitudinal halves having ears 3 secured together by the screws 4.
5 is a free carrier-box with cushioned ends, as distinguished from a box running in or on guides.
In the straight portion of the tube I provide two longitudinally@extending antifrictionribs 6, which are placed equidistant on opposite sides of the Vertical center of the tube when horizontal and upon which the box rides in its passage without contacting with the wall of the tube. I also provide another pair of ribs 7, diametrically and horizontally opposite each other, against which the box will Vnow and then be thrown in its rapid movement and which in` such cases keep the box from corninginto contactwith the wall of the tube. Iemploy the saln'eprinciple of antifriction-ribs in the curved portions of the tube, but they are located differently. As shown in Figs. 2 and 3, the ribs 6, which normally support the box, are on the outside of the curve, and the centrifugalforce of the box drives it against such voutside ribs. The ribs 7 are above and below the center of the tube at the bend when it lies horizontally and have the same function as the ribs 7 in the straight portion. The difference in the rela- -tive locations of the ribs in a straight and a curved portion appears in Figs. 3 and 4. The position of the ribs in the curve of the tube is always the same regardless of the position of the curve, whether vertical or horizontal,
as the box in its passage is always thrown against the outside ofthe curve. When the straight section, however, is placed vertical v instead of horizontal, the antifriction ribs should be located preferably equidistant about the tube, as appears in Fig. 5, instead of being located in only one-half of the tube. When arranged as shown in Fig. 5, the box in its passage will not engage the wall ofthe tube, but at all times theribs will prevent such contact. The advantage of this arrangement is that no guiderods, guide-ribs, or guide-grooves are required. The diameter of the curve is greater than that of the straight portion of the tube to allow the box to turn in it.
By indepeudentcarrier-box is meant one not guided by ribs or-runniug upon tracks and which is free from wheels or other guiding means. V
What I claim as my invention, and desire to secure by LettersPatent, is-
1. Acurved section of a despatch-tube having a pair of internal longitudinally-extending antifrictionribs placed on the outer curve of said section for preventing a free carrierbox engaging the wall' of the section.
2. A despatch-tubeconsisting of a straight portion and a curved portion combined, and internal longitudinally extending antifriction-ribs placed in said portion, those in the IOO straight portion being in the lower half thereof and those in the curved portion being in the outer half thereof.
3. The combination of a despatch-tube provided with internal longitudinally-extending ribs, and a Wheelless carrier box movable therethrough and directly engaging said ribs.4
4. The combination of an independent carrier-box, and a despatch-tube provided with a pair of internal longitudnally-extending ribs placed on the side of the tube against which such carrier-box Would move for preventing the box engaging the Wall of the tube.
5. The combination of a despatch-tube provided Witli three or more internal longitudinally-extending ribs, and a wheelless carrierherein named.
