HINGE FOR SAND SPOUTS.
Application fi1eq November 10, 1921. Serial No. 514,320.
T all whom it mag concern Be it known that I, JoHNFrsK lfVAno, a citizen of the United States, residing at Dunsmuinin the county of Siskiyou and State of California, have invented certain new and useful Improvements in Hinges for Sand Spouts, of which the'follow'ing is a V inperipheral lugs or ears 11 through which specification.
This invention relates to spouts for feed ing sand to the sand boxes of locomotives and has special reference to the hinge connecting the parts .of the spout whereby, the delivery end of the spout maybe permitted to swing out ofthe waywhen the spout is not in use. The invention'seelgs toprovide a construction of simple and inexpe iv form which may. be readily applied to the spout and will firmly connect the parts there.- of in either the closed or the open position. The invention is illustrated in-the accompanying drawings and will be hereinafter fully set forth.
In the drawings- Figure 1 is a side elevation of a portion of a sand spout having my improved hinge applied thereto;
Fig. 2 is a similarview but showing the spout open or in inoperative position;
Figs. 3 and 4 are detail perspective views of the members of the hinge.
The spout consists of an upper tubular member 1 which is connected with the dis charge opening of the sand hopper or bin in any convenient manner, and a lower'tubur lar member 2 which may be of any desired length and is adapted to he placed upon or over the sand box or dome upon the locomotive so that sand flowing through the alined spout members will be delivered into the box or dome. The diameter of the lower member 2 of the spout is somewhat greater than the diameter of the upper member 1 sothat the meeting end of the lower member or section may fit over the meeting end of the upper member, the end of the lowermember being cut obliquely relative to the longitudinal axis of the spout, as shown at 3. The upper hinge member at comprises a base block or body 5 through one end of which is formed an opening 6 to receive the hinge or pivot bolt 7. Disposed longitudinally of the base block 5 at the side edges thereof are the arcuate walls 8 which are adapted tofit closely around the upper spout section 1, as shown clearly in Figs. land 2., and
thejsaid walls have one end disposed at a right angle to their axis, as shown at 9, whilethe opposite ends 10 are arranged obliquely and extend from the opening 6 toward the opposite end of the side walls and away from the base block 5,,terminating a clamping bolt 12 is inserted to secure the sidewalls firmly around and against the spout section. The lower hinge member consists of a stirrup or collar13 which is" adapt ed to fit around the lower spout section and is provided with terminal ears 1 1 which are adapted to embrace the end of the base block 5 provided with the opening or passage 6, openings 15 being provided through the said ears 14 to receive the pivot or hinge bolt 7, as will be readily understood. Fastening bolts or rivets 16 are inserted through the collar or stirrup 13 and the wallet the spout section 2 and the said stirrup is provided with extensions 17 which are adapted to extend longitudinally of the spout sec-- tion and be rigidly secured thereto by rivets 18, the said extensions being provided with concave inner faces to it closely to the spout section.
Whenthe spout is in use, the two sections 1 and 2 will be axially alined and the end 3 of the section 2 will rest upon the inclined edges 10 of the upper hinge member, encircling the end of the upper spout section so that a continuous passage for the sand will be provided and the joint between the sections will be closed so that leakageof sand cannot occur. When the spout is not in usey the "lower spout section is swung downwardly, as shown in Fig. 2, about the pivot bolt 7 so that it will be out of the way of passing trains and any slight excess of sand which may be contained in the spout will not be deposited on the track or roadbed but may be caught in a conveniently placed receptacle. It will bereadily noted that I have provided an exceedingly simple hinge which may be readily applied to any sectional tubular conveyor and will firmly support the parts at their meeting'ends. .The
base block 5 is solid and presents a firm support for the pivot bolt so that bending of the bolt will be prevented and the inclined co-operating edges of the upper hinge meniberandthe lower spout section provide a I with obliquely disposed edges and adapted to encircle the meeting end of then-lined section, and piyotally connected hinge men'ibers secured to the respective sections where by to connectthe same, the hinge member v on the upper section having an inclined end to be engagedby and support the inclined end of the lower section 2; The combination of tubular spout sections, a hinge member provided with arcuate side walls adapted to fit snugly around the upper section adjacent the end thereof, means for clamping said walls upon said section, a hinge member secured rigidly about the lower spout section and having projecting portions adapted to span the first-mentioned hinge member, a pivotal connection between said projections and the end of the first-mentioned hinge member, and means whereby the first-mentioned misses hinge member may support the end of the lower spout section.
8. The combination of upper and lower spout sections, a hinge member comprising a base block having a. transverse passage through one end, arcuate side walls rising from the side edges of said base block and adapted to fit snugly around the upper spout. section, means for clamping said walls firmly about said spout section, the end edges ofsaid walls presented to the end of the spout section being inclined upwardly and rearwardly from the end of the spout section, a hinge member comprising a stirrup fitting about and rigidly secured to the lower spout section and having portions projecting beyond the said section and spanning the adjacent. end of the base block in the upper hinge member, and a pivot inserted through the said projections and the passage in thecsaid base block whereby to connect the hinge members, the end of the lower spout section projecting beyond the said stirrup and being inclined whereby it may rest upon and be supported by the inclined end edges of the first-mentioned hinge member.
In testimony whereof I affiX my signature.
