$PECIFICATION forming part of Letters Patent N 0. 736,651, dated August 18, 1903.
Application filed March 30, 1903.
To all whom, it may concern:
Be it known that I, MOSES C. SWEZEY, of W'esthaven, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Store-Service Apparatus; and I do hereby declare the following, when taken in connection with the accompanying drawings, and the numerals of reference marked thereon, to be a full, clear, and exact description of the same, and which.
said drawings constitute part of this specification, and represent, in-
Figure 1, a side view of a store-service apparatus constructed in accordance with my I 5 invention; Fig. 2, a top view of the same; Fig. 3, aplan view of the spring therefor; Fig. 4, a side View of the terminal head detached and with the ratchet housing-plate removed; Fig. 5, a side view of the removable ratchetplate; Fig. 6, a top or plan View of the terminal head; Fig. 7, a top or plan view of the removable ratchet-plate; Fig. 8, an end view of the slide with the latch removed; Fig. 9,a side view of the lower portion of said slide.
This invention relates to an improvement in store-service apparatus, and while particularly adapted for cash-carriers it is equally applicable for parcel-carriers, the object of the invention being to simplify the construction and arrangement of parts with a view of greater effectiveness in action and simplicity of installation, and the invention consists in the construction as hereinafter described,and particularly recited in the claims.
In carrying out my invention I employ a head 2, formed at its upper end with a socket 3, adapted to receive one end of a terminal post 4, which is secured in the socket by a setscrew 5. On this head are outwardly-projecting perforated lugs 6, more or less in number, to which stay-wires may be attached. Projecting outwardly from the upper end of the head is a pocket 7, in which a yokeoarrying arm 8 is pivotally mounted, and extend- 4 5 ing into the pocket from the upper and lower sides are set-screws 9 10, which bear upon the yoke-arm 8 forward of its pivots and so that the outer end of the yoke-arm may be raised or lowered. At the end of the head and be Serial No.150,158. (N0 model.)
low the pocket 7 is a projection 11, curved to form a recess 12 to receive a grooved roller 13, and from the rear of the head projects an arm 14, formed with a hub 15, providing a bearing for one of the trunnions of a double ratchet 16. The other trunnion 17, which is longer and angular, projects through a plate 18, corresponding to the arm 14 and adapted to be secured thereto, so as to form a housing for a pawl 19, which is mounted within the housing in position to engage with said ratchets. Above these arms is an opening 20 for the passage of a track-wire 21, which is wound on the shaft between the ratchets 16. Upon the yoke-arm 8 is a yoke 22, adapted to be secured thereto by a set-screw 23, the yoke having downwardlyextending outwardlybowed horns 24 25, to the outer ends of which the ends of a coiled-wire car-throwing spring are secured. This coiled-wire spring is wound with its ends 26 and central portion 27 of smaller diameter than the intermediate or side portions 28, and it may be made in two sections joined by a central bearing portion toward which the ends of the sections taper.
Mounted upon the track-wire 21 is a slide 29. The upper end 30 of this slide is bifurcated to pass on opposite sides of the yokearm 8, by which it is guided in an upright posi-- tion. To provide for holding it upon the wire, one side of the slide is formed with a longi- 8o tudinal groove 31, in which the wire extends, and it is held upon the wire by means of a vertically-arranged pin 32. Pivoted in the slide 29 is a latch 83, formed with a tripping arm 34. The nose 35 of the latch is adapted to en gage with a car-frame 36,which, as herein shown, has a single centrally-arranged wheel 37 and upwardly-extending ends 38 for engagement with the central portion 27 of the throwing-spring. The tripping-arm 3et,which 0 extends upward above the track-wire, is adapted to be engaged by a tripping-dog 39, adjustably mounted upon the yoke-arm 8. Secured to the slide 29 is a cord 40, which extends over the pulley 13 and is provided at its free end with a handle 41, whereby the slide may be drawnrearward.
Preferably and as herein shown a coiled spring 42 is arranged upon the track-wire 21 between the head 2 and the slide 29, the tendency of which is to force the slide-forward.
As herein shown, a buffer-block 48, of rubber or other suitable material, is placed in the forward edge of the slide against which the frame of the car may strike as it approaches the terminal, and upon the yoke-arm 8, in rear of the l yoke 22, is a buffer A.
' the latch 33 in the slide 29 will when the slide is drawn backward by the. operating-cord 40 be moved rearward, and as the caris engaged with the throwing-spring that spring will be placed under tension, and owing to the fact that the spring is larger in diameter at the sides than at the center it follows that the expansion of the spring will take place at the sides. At a predetermined point the arm 34: will strike the dog 39, thus releasing the car, which under the reaction of the throwingspring will project it forward upon the trackwire, the velocity of the throw depending upon the extent to which the throwin g-sprin g has been expanded, and this is determined by the location of the dog 39. After the car is thrown the operating-cord 40 is released, and under the action of the spring 42 the slide 29 will move forward to its normal position, which is determined by the location of the yoke 22. As the track-wires approach the terminals at different angles, it is necessary that the yoke-arm should be adjusted with relation to the track-wire, and this may be readily accomplished through the adjustingscrews 9 10, the outer end of the arm being raised or lowered accordingly as the screws are turned.
It will thus be seen that a very effective device is provided, the use of Wire for the operating-spring avoiding the necessity of replacement, which is often required when rubber is employed, as wire is much, more durable than rubber and not affected by temperature, and by increasing the convolutions of the spring at the sides it is less liable to become set when of a yoke secured to said arm, and an operating-spring comprising a coiled wire, the con-/ volutions of the coils at the sides of greater diameter than at the ends, substantially 2;
2. In a store-service apparatus, the combination with the head thereof and yoke-arm,
of a yoke secured to said arm and an operating-spring comprising a coiled wire the convolutions of the coils at the center and ends being of smaller diameter than the interme diate portions, substantially as described.
3. A store-service apparatus having a terminal head comprising a socket for attachment to a terminal post, a pocket in which the yoke-arm may be pivoted, arms in which an operating-cord pulley may be mounted,and an arm for supporting the track-wire ratchet, said head, pocket and arms formed integral, substantially as described.
4. In a store-service apparatus, the combination with the terminal head, of an outwardly-proj ectin g pocket, a yoke-arm mounted in said pocket, adj usting-screws extending into said pocket for changing the inclination of the yoke-arm, substantially as described.
In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
