ART OF COLLECTING, SIFTING, AND REMOVING ASHES.

Specification of Letters Patent.

Application filed May 2, 1918. Serial No. 232,030.

To all whom it may concern Be it known that I, JOHN F. LINTON, a

citizen of the United States, residin at Brooklyn, in the county of Kings and tate of'New York, have invented new and useful Improvements in the Art of Collecting, Sitting, and Removing Ashes, of which the following is a specification.

This invention relates to certain new and useful improvements in the art of collecting, sifting and removing ashes.

In large cities the removal of ashes, especially from ofiice buildings, apartment houses, hotels and similar modern structures presents an industrial problem which is difficult of satisfactory solution because of the restrictions and obstacles encountered in the performance of the work. For instance, in a greatcity like New York, especially on Manhattan Island, land is very valuable and there are hundreds of buildings of extraordinary' height, ranging from ten to fifty stories, congested within a limited area and extending substantially in solid rows along opposite sides of relatively narrow streets through which pass,at all hours of the day, continuous streams of traffic, both foot and vehicular. These buildings are almost with out exception equipped with modern heating and power plants utilizing batteries of steam boilers, the operation of which results in the accumulation of tons of ashes each day. The disposal of these ashes is a matter of expense and annoyance, for it usually entails the addition to the equipment of each boiler room of dozens ofelarge, costly, alvanized metal ash cans into which the as es are shoveled each day, the filled cans being subsequently hoisted to the sidewalk level. through the agency of elevators provided for this particular purpose, or else, when conditions will not permit the installation of such a special elevator, the cans must be carried by laborers to the sidewalk, the ashes being subsequently collected by the usual ash carts making the round from building to bullding. An elevator or elevator leg of the type usually employed for hoisting the ashes to the sidewalk level costs from seven hundred to five thousand dollars with one hundred I per cent. cost of maintenance per annum, while the cost of the cans alone for a building handling about two tons of ashes per day will approximate six hundred dollars per annum, as these metallic cans rapldly deteriorate due to excessive wear caused by the abrasiveness of, and the sulfuric acid in, the ashes. In addition to this, the dust and annoyance incident to 'cartin the ashes to the elevator and from the e evator to the ash cart is so great as to constitute. a veritable nuisance. Furthermore, the local building regulations usually prohibit the instal-- lation of bins, elevator legs, and all overhanging projecting structures at the eliterior of the building, or on, or over the street, because of the danger, obstruction and inconvenience to pedestrians. It will also be obvious that where great quantities of ashes have to be handled two or three times in conveying the same from the boiler room to the ash cart, the expense, time consumed, and labor required for such a procedure constitutes a considerable and serious item in the cost of maintenance of the building.

Patented Sept. 2,1919.

The salient purpose of the present invention is the elimination of the above recited disadvantages incident to the ash disposal problem as encountered under the conditions mentioned. To this end I propose to permanently install within'the building a suction line or conduit having an ash receiving intake at the ash pit or box, preferably located adjacent the furnace, the delivery end of the suction line. or conduit terminating at a man-hole preferably situated adjacent the street curb, or at a convenient point outside the building. I also ovide an automobile bin or travelin van aving a closed body or chamber divided by a partition o'r floor into an upper and a lowercompartment. Suitably locatedv within the lower compartment is a suction inducing device, such as a suction blower, having its intake communicating with the upper compartment from the power shaft of the en 'ne which 'drives the automobile, a suite le clutchv mechanism being provided so that the engine may be thrown out of propelling relation to the vehicle and into fan driving relation, or vice versa as may be desired, the engine thus being employed for both propelling the vehicle and for operating the suction mechanism. Connected with the upper compartment and forming a part'of the automobile equipment is a short suction pipe section which extends exterior-1y of the vehicle body and is adapted to be coupled, preferably by means of a short flexible pipe or a coupling attachment to the endofthe sucr 1 alongside the curb and couple onto the suction pipe at the .man-hole, and thenthrow ,the power shaft of the engine into driving relation with the suction fan so that the ashes will be; drawn up through the conduit and into the upper compartment of the van. The partition forming'the floor of this upper compartment 'is inclined so that the ashes will pass. downwardly by gravity, and then, at stated times may be permitted to pass through a door, or doors, into an ordito the bottom of the ash pit or Well with the nary ash' cart driven alongside the van. I By this arrangement, the ashes may be quickly and completely removed without the noise and dust usually incident-to handlingunder ordinary methods, and with far greater economy as the maintenance cost need not exceed two cents per ton of ashes'removed.

' Of course, the van may be driven from buildingto building for the repetition ofthe re-. moval operation as will be readily understood.

Furthermore, I propose to provide means.

whereby the ashes may pass from the bin into and through the intake of the suction pipe without banking, or clogging the intake thus avoidingthe possibility of interference with or blocking the suction.

I also propose to provide means for sifting the ashes so that such cinders as can be used for fuel may be recovered, while the fine dust and other like non-usable products of combustion may be drawn off through the suction pipe.

With the. above recited objects and others of a'similar nature in view, my invention consists in the art of disposing of ashes set forth in and falling within the scope of the appended claims. In the drawings: V Figure 1 isa view partly in elevation and partly diagrammatic showing the apparatus ready for carrying out the invention. Fig.;2 is a view in side elevation of the automobilevan and its connection with the man-hole.

Fig.7 3 is a vertical, longitudinal, see

This screening apparatus -1nay .be of any preferred construction and dust and a'shes separated from the cinders in the screening operation will drop down into the pit or well B, forming an inclined bank such as indicated by the dotted line 5.

Connected with the lower portion of the pit or well B is an ash intake member indicated as a whole by the letter D, and

shown in detail in Fig. 3. This intake comprises a horizontal pipe section 6 open at both ends and flanged as at 7, this horizontal section .6 having formed integral therewith and intermediate its'ends an upwardly and rearwardly inclined supply pipe 8 flanged at its upper end as at 9 and suitably secured bore of the supply pipe inalinement with "the opening 10 of the pit. The forward wall section of this supply pipe 8 is ummaterially in the operation of the apparatus, for the peculiarly shaped inclined supply pipe 8 insures that the ashes will flow in an unobstructed path intothe horizontalsection 6 of the intakeand will not bank in the latter so as tointerfere with the line of suction or draft through'the intake in the direction indicated by the arrow-in Fig 3. Should an ordinary T intake be employed in the apparatus, it will be found that there will bea tendency of the ashes to bank'or clog in the horizontal section 6' of the intake directly'below the communication of the supply pipe or Vertical section of the intake so that the draft or suction is obstructed. \Nith my intake, however, the

dust are directed downward at 5' ashes an an angle and introduced into the draft or suction in the direction of, or along, the flow of the latter, so that it is impossible for the banking of the ashes to occur. Connected with the forward opening end of the horizontal section 6 of the intake is anelbow 12 having coupled therewith the lower end of the main ash conduit shown at 13, the upper end of this conduit terminating within the'n'ian-hole 14 preferably located exteriorly of the building, and in the present instance, adjacent the curb or street. -The upper end of this conduit 13 which projects into the man-hole is provided with a suitable coupling member 15. stood that the ash pit. the intake, the main ash conduit 13 and the man-hole H at which the dischargeend of the conduit terminates all form of a part of the ash handling paratns permanently installed therein.

To remove the ilSllLHfl'Ulll buildings-so equipped, I provide a traveling or autmno bile van or bin shown at E; and having 111130 j It willbe under- 1 body portion F in the nature of a relatively large closed chamber. This body portion is divided by the inclined partition 16 into an ash receiving suction chamber 17 and a lower chamber 18. T Within the'latter is mounted a suction device, in the present instance, a suitable suction fan 19 provided with the suction pipe 20 the upper end of which extends through the wall section 21 and into the upper or ash receiving suction chamber. This suction fan may be driven in any suitable manner such as by a'chain' driven upalongside the curb,'as shown in Fig. 1, and the flexible pipe section 25 having a coupling member 25 co'mplemental to the coupling member 15 of the main ash conduit 13 is connected to the latter at the man-hole. The upper end of this flexible pipe section 25 is connected as at 26 to a short suction pipe 27 which with the pipe section 2'5 forms apart of the van equipment and leads at its upper end into the ash receiving suctionchamber, as shown at 28;

When the suction pipe of the van has been coupled with the pipe 27, the engine may be thrown into driving engagement with the suction fan by shifting the clutch for this purpose, and suction being exerted in' the ash receiving chamber through the pipe 20, the ashes will be drawn from the bin B through the intake D up the pipe 13, through the pipe 27, and into the upper chamber 17, one or more suitable ba ing screens 29 preventing'the ashes passing to and through the suctlon pipe 20 of the fan. The ashes will drop downwardly by avity onto the inclined partition 16, an when desired, as when the upper chamber is well filled with ashes, or all of the ashes have been removed from the ash-pit B, or at,

other times, an ordinary ash cart, conventionally. shown at G, is driven into position alongside the van as shown in Fig. 1, and by opening one or both of the doors 30 controlling the delivery chutes 31 in the side of the van, the ashes may be permitted to discharge into the cart. These doors 30 may be opened and .closed in any suitable manner, such as by the rack and pinion device 32. As soon as the ashes have been removed from the ash pit, the suction pipe of the van is uncoupled from the main suction conduit 13 of the building installation,

- and the van may be driven to the next building permanently equipped with the parts within a neighborhood or territor of the apparatus as herein described, so that the removal of the ashes from the next building may take place. The operation may be repeated of course as the van makes its rounds from building to building, accompanied by the. ash cart, so that the ashes may be removed from a number of buildings with great speed and without noise and dirt.

While I have herein SllO'In and described one particular manner of practising my invention, I wish it to be understood that I do not wish to limit myself to the precise details herein set forth by way of illustration, as modification ,and variation may be made without departin from the spirit of the invention or exceeding the scope of the appended claims.
