To all whom it may concern:

Be it known that I, MARSHALL G. QuAcK- ENBUSH, a citizen of the United States, residing at Colorado Springs, in the county of El Paso and State of Golorado,have invented certain new and useful Improvements in Fluid- Pressure Couplings; and I do declare thefollowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to the letters of reference marked thereon, which form av part of this specification.

This invention relates to new and useful improvements in automatic couplers for steam, air, and fluid hose-pipes for use in connection with air-brakes, steam-pipe connections, 850.; and it consists in the provision of means whereby pipes may be coupled without the necessity of a person going between the ends of cars, as is now commonly the custom and which results in great loss of life and various accidents.

The invention more specifically comprises an automatic coupling apparatus of this character com prising an adjustable funnel-shaped guide member adapted to receive a plunger having ducts which communicate with pipes and in the provision of a device whereby the ducts of the plunger are thrown into communication with fluid pressure pipes and valves automatically actuated for opening communication between the train-pipes and the pipes upon two'cars which have been antomatically coupled.

The invention consists, further, in various details of construction and in combinations and arrangements of parts,which will be hereinafter fully described and then specifically defined in the appended claims. 1

My invention is illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this application, and in which drawings- Figure 1 is a side elevation of my improved coupler, shown as attached to the draw-head of a car-coupler. Fig. 2' is a top plan-view of two couplers connected together, portions of the couplers being shown insection. Fig.

Reference now being had to the details of the drawings by letter, A designates the drawhead of a car-coupler, and secured to the under face thereof are the brackets B and O, which support the fiuid-pressure-pi pe-coupling apparatus. Swivelly mounted upon and depending from the bracket B is a forked yoke D, the arms of which carry a pivotal pin D. upon which is pivotally mounted a slotted bar E. Mounted upon a pivotal pin E, which is supported in the walls of the slotted portion E? of said bar, is a draw-bar F, having a staple F secured to its under edge, to which one end of aspring G is connected, the other end of the spring being fastoned in an aperture 6 in the lower tapering end of said bar E. 7 The lower end of the bracket-armO has an opening through which the draw-bar F has a passage and has alateral play, the marginal ends of said opening being illustratedby dotted lines 0 in Fig. 2 of the drawings. Said draw-bar F has a head H, having shouldered portions H and H on either edge thereof, said shoulders H being slightly concaved, while the shoulders H are disposed at an angl e, as illustrated in Fig. 1 of the drawings. Links Kand K are mounted upon pivotal pins K adjacent to said shoulders, and the forward ends of said links are in turn pivoted to a block I, which carries pins 1 adjacent to the shouldered portions of said block I, said shoulders being provided for the purpose of allowing a limited vertical movement to the links. Said block I has socured thereto a cross-bar J, one end of which supports the pipes L and the other end of which is forked to receive the shank portion N of the funnel-shaped guide member N, said shank portion N being mounted upon a pivotal pin M, Fig. 2 of the drawings, and projectinglaterally from one side of the shank portion N is a lug N adapted to bear against aspring-actuated plunger N which is mounted in a hole in said cross-bar J. The inner end of said plunger N has a head adapted to bear a ainst a spring 72, interposed between said head and the bottom of the hole'in which the plunger is mounted, and serves to hold UNITED 'Sjr T s Patented November 10, 1903.

Application filed May 15,1903,

To all whom it may concern:

Be it known that I-,ELMER zen of the United States, residing at Rolling Prairie, in the county of Laporte and State of Indiana, have invented a new and useful Mail-Box, of which the following is a specification.

This invention relates particularly to improvements in that class of mail-boxes employed in the rural free-delivery system of the Post-Office Department.

The object. is to provide a structure which is very simple, so that it may be constructed at small cost and sold at a low price, said structure at the same time being weatherproof, so as to properly protect its contents from the elements, and thoroughly strengthened to withstand ed forcing of the same by an unauthorized person. To this end a box is provided have ing very few seams and joints, the latter bein gcovered when-the members are closed,said members being surrounded by a strengthening or reinforcing strip, to which hinge connections are made, so that the walls proper are relieved of the most destructive strains and wear.

The preferred form of construction is illustrated in the accompanying drawings, where.- 1n-- Figure 1 is a perspective view of the box.

' Fig. 2 is a longitudinal sectional view through the same. Fig. 3 is a vertical transverse sec.- tional view. Fig. 4 is a detail bottom plan view of onecorner of the box, and Fig. 5 is a detail sectional view showing the side margins of the receptacle member.

Similar reference-numerals indicate corresponding parts in all the figures of the drawrugs.

In the embodiment illustrated a receptacle member 10 is employed having a semicylindrical wall 11, the side margins 12 of said wall being doubled back against the outer face of the same and having the edges outturned, as shown at 13, to provide front and rear outstanding flanges, which flanges are thus located below the upper edges of the receptacle member. The end walls 14 of this member are preferably in the form of circular disks, the lower portions of said disks being suitably seamed, as shown at 15, to the end edges E. Rnnsn, a citi-x hard usage or the attemptsaid beads.

of the wall 11. The upper portions of the end walls extend above the side edges of the receptacle member. Suitably secured to the outer face of'the wall 11 is a transverselydisposed supporting-yoke 16, the terminals of which are outturned, as shown at 17, and rest against the under sidesof the flanges 13. The

central or lower portion of the yoke is attached by suitable rivets 18 to a bracket 19, which bracket is constructed to be fastened to a post 20 or other suitable support.

A cover member 21 is employed, which is arranged 'to fit over the open side of the receptacle member, this cover member comprising a semicylindrical wall 22, to the end edges of which are seamed end caps 23, these end caps being adapted to pass over the outer faces of the end walls 14 of the receptacle member, whereby the upper portions of said end walls will be housed within the cover member, so as to serve as supporting means for said member'and also thoroughly break the end joints between the members. The side edges of the cover member are also provided with outstanding flanges 24:, formed bybending the side margins of the wall 22 out wardly. These flanges 24: are arranged to cover the flanges 13 of the receptacle member, and their outer edges are provided with longitudinal beads 25,- inclosing strengthening-rods 26, that project beyond theQends of Reinforcingstrips 27 are attached to the ends of the cover member and extend transversely across and beyond the same, forming cars 28. The cars are provided with suitable openings, in which are riveted theends of the strengthening-rods 26. As a result, a reinforcing-frame completely surrounds the cover member and, in was to thoroughly strengthen the same. The flanges 13 of the receptacle member are also provided at their free edges with beads29, in which .are inclosed front and rear strengthening-rods 30 and 31. The rear rod 31 projects beyond the ends of its bead and passing through the adjacent cars 28 of the reinforcing-strips 27 co'nstitutesahinge connectionbetweenthetwo members. The corresponding front flanges of the members are provided with alined openings 32, and the end of the yoke 16, located directly beneath the same, has a similar opensaid cross'piece and having a play in the apertures of the shank portion of the guide member, a latch pivoted in a slot in said shank portion and serving to lock said guide member from lateral movement when uncoupled, a tapering plunger-head mounted on the other ends of said pipes, ducts leading through said plunger and communicating with the opposite ends of said pipes, an inclined member secured between said crosspiece and the plunger, a pressure-cylinder, a diametrically-disposed passage-way through said cylinder, a piston-valve working at right angles to said passage-way pivoted to the shank portion of the funnel-shaped guide,

coupling plunger-head, a cross-piece communicating passage-ways between said cylinder and one of said coupler-carrying pipes and the train-pipe, as set forth.
