IlIAIL-BAG searches on TRANSFERRER.

To all whom it may concern:

Be it known that I, GEORGE J. MEIER, a citizen of the United' States, esiding at Buffalo, in the county of Erieand State of New York, have invented a new and useful Improvement in Mail-Bag Catchers or Trans ferrers, of which the following is a specifi cation. V

This invention relates to a mail bag catching and delivering apparatus of the general character shown in -letters Patent of the United States T granted to me May 5', 1908,, 1 .0. 886,832.

The object of the present invention is to provide simple, durable and efficient means whereby the delivery arms and the receiving hook are normally held in positionfor delive ering and receiving a mail bag and after'such transfer of the bag hasbeen effected the arms and hookwill beretracted so as-toavoid injuring persons on the car or adjacent to the track which sometimes occurs by the-use-of mail bag transferring devices in whichthe delivery arm projects from the side of the car and the receiving hook projects toward the car track after the transfer of the mail bag from the former to the latter has been effected. i

same as the means for transferring a bag from the station to the car but in the following description and the accompanying drawings only the means for. transferring the bag from the car to the station are disclosed, but it is to be understood that the same also applies to the means for transferring a mail bag from the station to the car.

As shown in Fig. 1, the car B is provided with upper and lower cross pieces A, A which eX'tendacross its door opening and which are provided near one side of the door opening with outwardly projecting upper and lower lugs 12, 6 respectively. Pivoted to these lugs is a pair of horizontally swinging upper and lower brackets c, c which are connected by rigid upright guide rods C. In the outer ends of these brackets an upright right and left hand screw D is journaled which is held against endwise movement in the brackets and provided at its upper end with a crank or handle (2 for turning the screw. E, E} represent a pair of arms which support the mail bag c in position for delivering the same to the mail station. These delivery arms are slidably mounted at their inner ends on the guiderod C and are provided in front of the latter with threaded openings which receive the right and left thread of the screw D,-so that upon turning the latter-in one or the other direction, the delivery arms are caused to approach or to recede froineach other and adapt them to the length of. the bag which is to be supported. "At their outer ends, the delivery arms are provided with catches F which are adapted to engage eyes or, loops 0 at the upper and lo'werends of the mail bag or pouch and which preferably consist of vertically swinginglevers pivoted on the arms E, E and yieldiiigly held in engagement with the eyes of the bag by springs g. The swing brackets permit the bag delivery arms to be unfolded or projected laterally into their operative position from the side of the car, as shown by full linesin Figs. 1 and 2, or to be folded orretracted inits inoperative position parallel with the side of the car, as shown by dotted linesin Fig. 2. v

N represents the bag catching or receiving hook of the: mail crane which is supported on a'post or standard 0 adjacent to the railway track at the station and which is arranged withits mouth facing the bag to be engaged,

so that thesame enters the bight of the hook and isheld thereb in a well known manner. y

The receiving hook is hinged to swing vertically on the post 0 by a horizontal pin or pivot p passing through an arm n on the inner end of the hook and the two sections p of a bracket which project from the post on op posite sides of the inner end of the hook, whereby the latter may be swung upwardly into its horizontal operative position for receiving a bag, as shown by full lines in Figs. 1, 2 and 8, or dropped into a vertical or pendent position when not required for use, as shown by dotted lines in Figs. 1 and 8.

An oblique detent spring Q extends across the mouth of the hook for retaining the mail bag therein. This spring is secured at its inner front end to the inner end of the hook and to the outer rear end of this spring is pivoted a double detent link R which normally extends across the mouth of the hook, so as to retain the contracted waist of the mail bag in the bight of the hook and which is guided on the inner end of the hook by means of pins 8 on the latter engaging with longitudinal slots 8 in the members of the link.

All of the mechanism above described is substantially the same as that in Letters Patent referred to. In the mechanism of this prior patent the bag delivery arms and the receiving hooks remained in their normal operative or projecting position until retracted by an attendant which endangered person's standing adjacent to the moving mail car and also persons riding on the latter. For the purpose of causing the delivery arms and the receiving hook to be automatically retracted after the mail bag has been transferred from the former to the latter, the following means are provided :-T represents a jaw or shoulder arranged on one of the brackets of the delivery mechanism, pref erably the lower one, at a point in rear of its pivot and having its face undercut or beveled from its upper side inwardly toward its lower side, as shown at t in Figs. 1, 5 and 6. U represents a vertically swinging catch or de tent pivoted on the lower lug b and having a weighted rear arm a while its front arm a is provided with a beveled face a which is adapted to engage with the undercut beveled face t of the bracket 0 when the delivery brackets and their bag supporting arms are swung out into their operative position, as shown in Figs. 1, 2, 3, 5, 6 and 7.

N-hen it is desired to use the bag delivery arms the same are swung outwardly into their operative position until the jaw T is behind the front arm of the catch U after which the latter is turned, so that said arm is in the path of the jaw and is engaged with the same upon moving the lower bracket 0 and connecting part inwardly for this purpose. The jaw T is held in engagement with the front arm of the catch by means of a spring V which tends constantly to turn the brackets and the parts connected therewith inwardly or into their retracted position.

This spring is preferably wound around the depending pivot pin 0 of the lower lug c and bears at its opposite ends against a stationary part such as a pin 12 on the car body and a part moving with the lower bracket 0 such as the lower end of the adjusting screw. The parts of the delivery device remain in this position and hold the mail bag at the side of the car so long as the pressure exerted against the mail bag and its support is not sufficiently great to overcome the tension of the spring When the mail bag is caught by the mail hook the impact against the bag support of the delivery device causes the lower bracket 1) to be first turned outwardly to a sullicient extent against the tension of the spring to cause the jaw T to be carried beyond the front arm of the catch U. The instant this occurs the catch U owing to the preponderating weight of its tail or rear arm causes the front arm thereof to be antomati sally raised out of the path of the jaw T, so that as the spring V recovers itself, it is no longer restrained but is free to turn the upper and lower brackets c, c and delivery arms E, E from their projected position inwardly to their retracted position along the side of the car, whereby the same will not hit persons standing adjacent to the track when not in use. The outward movement of the brackets c, c and the parts carried thereby under the impact of the blow of the hook against the mail bag is preferably limited by means of stops r formed on these brackets and engaging with the rear sides of the lugs I), I).

The preferred means for causing the bag receiving hook to be held horizontally in its operative position preparatory to receiving the bag and to be released so that it can drop into a vertical position when a bag enters the mouth of the hook, is constructed as follows: W represents a cam shaped heel or extension arranged on the arm of the receiving hook in rear of its pivot. w represents a vertically swinging latch which is pivoted at its rear or inner end on the support of the hook and adapted to engage with the upper side of the heel of the hook arm for holding the latter in its horizontal operative position. The latch is held in this position by means of a horizontally swinging lock or lever X which is pivoted on the support of the hook arm and is provided with a front arm or nose ;r which is adapted to engage with the top of the latch, as shown in Figs. 2 and 9, and also is provided with a rear arm .r which is adapted to be engaged by the rear end. of the double link R. The latter and the detent spring (I operate as a trip mechanism whiehemitrols the dropping of the bag receiving hook. As a bag enters the mouth of the bag receiving hook and deflects the spring (1 and link llv the latter y pushing against the rear arm of the locking lever causes the front arm of the Hill llt)

., the inward movement same to be disengaged from the top of the latch. The instant this occurs the heel of the hook arm which is pressing constantly upward against the latch now lifts the same and the hook together with the mail bag in the same drop by their weight into their lowered position. I

The means for holding the bag delivery arms and the bag receiving hook in their operative position are very strong and durable and hold the parts reliably in place while at the same time permitting of retractingthej delivery arms and receiving hook promptly and with certainty after the transfer of the mail bag has been effected, so that the li a' bility of striking persons on the car or adjacent to the track is avoided.
