MAIL-BAG CATCHER.

T o all 'whom it 'may concern:

Be it known that I, JosEri-I A. SCHINNER, a citizen of the United States, and a resident of Greenfield, in the county of Highland and State of Ohio, have invented a new and Improved Mail-Bag Catcher, of which the following is a full, clear, and exact description.

The purpose of this invention is to provide novel details of construction for a mail bag catcher that adapt it for reliable service, either to catch a mail bag and deliver it vat the open door 0f a mail car on a moving train, or transfer a mail bag from a train in motion to a station at the side of the track on which the train is moving.

The invention consists in the novel construction and combination of parts, as is hereinafter described anddefined in the appended claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a partly sectional plan view of a portion of a mail car, and a plan view of the improved bag catcher adjusted for grabbing a Inail bag from a stationary support; Fig. 2 is a front view of the improvement in position on a car, the parts thereof being adjusted as shown in Fig. 1; Fig. 3 is a plan view of details similar to those shown in Fig. 1, but represented in closed adjustment, holding a mail bag indicated by dotted lines; and Fig. l is a transverse, partly sectional view of the bag catcher and a door jamb in part, the section being taken substantially on the line 4-4 in Fig. 1.

In the drawings, that represent the improvement mounted on the easement jambs of a doorway, in a side wall of a mail car body, 5, 5, indicate said jambs. At a suitable height from the floor of the car, two

similar bracket blocks

6, 6, are secured oppositely on the j ambs 5, 5. A rock shaft 7, having journaled ends a, c, is rockably secured on the blocks G by an engagement of said journals within sockets formed oppositely in said bracket blocks. Upon the normally outer side of the rock shaft 7, which is preferably rectangular in cross section, a base plate 8 is secured at a suitable point, that may be nearer one of the doorway jambs than the other.

In the base plate 8, a longitudinal slot b is formed, that is parallel with the rock shaft Specification of Letters Patent.

Patented 1, 1910.

' Application filed December 13, 1909. Serial No. 532,727.

f. A slide block 9 seats upon the base plate 8 and is loosely secured in place by a shouldered shank on a depending handle 10; said shank that passes up through the slot at its upper end, is attached to said block, thus enabling the sliding movement of the slide block to be effected by manipulating the handle 10. On the base plate 8, between the rock shaft 7 and the slide block 9, an elongated jaw bar 11 is secured, against which the block 9 slides, and as shown, the bar 11 is eX- tended at one end beyond the base plate, and forms a gripping jaw 11a for the bag catcher. The outer corner on the slide block 9, that is nearest to the fixed jaw 11, is removed and an inclined edge portion cis thus formed thereon, as appears in Figs. 1 and 3. Upon the end portion of the base plate 8 that is adjacent to the rear end of the fixed jaw 11a, a gripping jaw is pivoted, said jaw 12a being formed on an obtuse angularly-bent bar 12 that is rockably secured upon the base plate by the pivot d, which passes loosely through a perforation in said bar at its angle e an is secured in the base plate near the side edge thereof which is farthest from the rock shaft 7.

The relative position of the bent bar 1Q, serves to dispose the gripping jaw 12a thereon opposite to and spaced from the fixed jaw 11a. The free end of the jaw bar 12, that is disposed near to the inclined edge c on the slide block 9, is provided with a small roller g, which contacts with said edge when the gripping jaw 12at is rocked away from the fixed jaw 11, and it determines the degree of separation between said jaws.

Between the pivot d and roller g, one end of a link bar 13 is pivoted on the jaw bar 12, as shown at f; the other' end of said link that laps upon the slide'block 9 is thereon pivoted near the sloped edge c on the latter, as shown at f in Figs. 1 and 3.

Upon the base plate 8 near the end portion of the fixed jaw bar 11 that is farthest from the jaw 11a thereon, one end of a flat rock arm 14; is pivoted, as shown at Z, and on the adjacent end portion of the slide block 9, near its outer edge, one end of a similar rock arm '15 is pivoted, as shown at 7L in Figs. 1 and 3, the remaining ends of said rock arms being lapped together and pivoted upon each other, as shown at c' in said views. Upon the end of the rock arm 141, that is disposed above and near the jaw bar 11, one end of a pusher rod 16 is pivoted, as

' jaws nu, 12a, ai@ sutiable L said jaws,

12 being' eiiected by shown at m, said rod extending toward and above the jaws 11, 12a, and having slidahle engagement with a postI 17 through which .it passes. On the end of the pusher rod 1G that is disposed above the gripping aws 11a, 12a, an abutment arm 16 is secured, which extends laterally therefrom and across the gripping arms.

A handle 18 is secured on the fixed jaw bar 11 at a convenient point, so as to project laterally therefrom and away from the side of said bar whereon the edge of the slide block 9 has loose contact. As shown in Figs. 1 and l, if the handle 1S is raised into a horizontal position from the normally pendent one shown by dotted lines in Fig. 4, and the handle 1() is moved away from the movement of the block 9 away from said jaws will cause the jaw 1,2a to rock away from the fixed jaw 11L its full throw and thus open a gap between this divergence of the pivoted aw the link bar 13, which pulls upon the jaw bar 12 when the slide block 9 is moved rightward. The roller g on the end of the jaw bar 12 only impinges upon the incline c when the pivoted jaw 12*rl is nearly opened, and it will be noted in Fig. 2 that the impingeinent of said roller on the incline mentioned, serves to enforce the complete open adjustment of the pivoted jaw, and retains it in such condition until the slide block is moved away from the pivoted jaw. It will also be noted that the rock arms 111, 15, cooperate with the link bar 13, serving to retain the block 9 in free slidable engagement with the base plate 8.

dien the handle 16 is rocked into a horizontal position, the catcher device will be projected out of the car door opening, and thus loe disposed in the path of a mail bag that is supported in the usual manner at a railroad station, and adjacent to the track whereon the mail car is moved.

Assuming that the catcher device is properly adjusted into a level position, that the is diverged from the jaw 11, and that the car having the improved catcher device is traversing the railroad track in the direction of the arrow m in Fig. 1, if a mail bag is supported removably by usual means, so as to be disposed in the path of the opened jaws 11a, 12a, the trend of the car will cause the mail bag to impinge against the abutment arm 16a and slide the rod 16 toward the rock arm 14 whereon it is pivoted at its opposite end. The rock arms 14, 15, will thus be rocked into the relative positions shown in Fig. 3, which will adapt the arm 15 to push the slide block 9 leftward, thus rocking the link bar 13 .into the position shown in said view, and simultaneously closing the free end of the gripping' jaw 12a toward the corresponding end of the fixed jaw 11a. It will be seen that the closure of the arm l2 as explained. will grip the inail bag and hold it, so that said bag will be rcmoved from its stationary support and be ill position tor removal into the mail car.

lt will be apparent that it the catcher dcvice is placed on a support adjacent to a railroad track, a mail bag that may be hung on a horizontal arm extended parallel with the side of a mail car near the door therein. will be removed trom said hook as the car rapidly passes the station, due tothe impact oi"A the bag on the abutment arm lo,

Having thus described my invention, l claim as new and desire to secure by Letters Patent:
