acorporation of Dela- Application January 19, 1948,.Serial No. 3,018

This invention relates to improvements inoperating handle levers for rotating the actuating bars of door fasteners of the rotary type.

One object of the invention is to provide ina rotary bar door fastener, actuating lever means vided with a forked connecting portion which embraces the operating bar at opposite sides and is pivoted to the bar by a pin extending through the spaced members of the forked portion and the bar, wherein one of the spaced members of the forked portion is an integral part of the A handle lever, and the other member of said forked portion is in the form of a separate section, which interlocks with retaining means on said handle lever and is held in rigid interlocked condition with respect to the handle lever proper by means of the pivot pin.

Other objects of the invention will more clearly appear from the description and claim hereinafter following.

In the accompanying drawings forming a part of this specification, Figure 1 is a broken, front elevational view of a wall member having a door opening therein, and a pair of hinged doors for closing the opening, wherein the doors are provided with a fastener of the rotary bar type, illustrating my improvements in connection therewith. Figure 2 is a broken rear elevational view, on an enlarged scale, of the structure and associated mechanism at the mid portion of the operating bar of the door fastener shown in Figure 1. Figure 3 is a horizontal sectional view, on an enlarged scale, through the operating bar of the door fastener, corresponding substantially to the line 3--3 of Figure 1. Figure 4 is a side elevational View of Figure 3, showing the operating bar broken away. Figure 5 is a horizontal sectional view, partly brokenaway, corresponding substantially to the line 5-5 of Figure 4. Figure 6 is a view, similar to Figure 5, with the operating bar omitted and showing the separable section of the handle lever detached from the lever member proper.

In said drawings, IIi designates the end wall member of a refrigerator automobile truck having a door opening II therein, which is closed by 1 Claim. (Cl. 292-218) a pair of hinged doors I2 and I3. Each door member is provided with the usual sets of hinges li -I4 along the vertical outer edges thereof by which the door is supported. The door I2, which is that first closed, and the door 13 have meeting edges which are beveled and soinclined that the door I3 holds the door I2 in closed position and wedgesthe same shutwhen the door operatingtmechanism'is actuated. The door I3 is provided: with a rotary operating bar door fastener of well-known design, comprising the usual vertically disposed rotary bar I5, provided with keeper engaging crank members at the top and bottom: ends which engage with slotted keepers fixed to the car wall, onlythe lower crank member and lower keeper being shown in. Figure 1 of the drawings, the same being indicated by ming engagement of the keeper engaging crank members with the keepers. As is common practice, the bar I5 is supported for rotation by the usual top, bottom, and intermediate guide or bearing brackets secured to the door, only the intermediate and bottom guide brackets, which are indicated by I8 and I9, respectively, being shown in the drawings.

In carryingout my invention, I provide a twopart operating handle lever A for rotating the bar I5, comprising sections B and C, and a pivot pin D for swingingly connecting the lever to the bar and holding the sections of the lever in rigidly interlocked condition.

The operating lever A is in the form of a flat bar having a hand grip portion 20 at its outer end. The section B of the lever A, which carries the hand grip portion 2?], is laterally enlarged, adjacent its inner end, as indicated at 2i, and terminates in a longitudinally extending, fiat, platelike portion 22, offset to one side of the longitudinal central axis of the lever. The platelike section is of substantially triangular contour, as shown, and is provided with a laterally inwardly projecting flange 23 along its upper edge, which is continuous with the upper portion of the lateral enlargement 2| of the section B. As shown most clearly in Figure 3, the flange 22 terminates short of the inner end of the platelike section 22. of the section B of the lever A is recessed to provide a longitudinally extending pocket 24, the side walls of the pocket being defined by a rela tively short wall section 25 at the outer side, terminating short of the end of said enlargement,

The laterally enlarged portion and a wall section 26 at the inner side of said head, continuous with the platelike portion 22 and terminating at a point spaced rearwardly from the end of the wall 25. The pocket is thus provided with front and

rear openings

21 and 28.

The section C of the lever A includes a triangular, platelike portion 29, similar to the triangular, platelike portion 22 of the section B of the lever. The platelike portion 29 is provided with a longitudinally extending. relatively thick, keylike rib 30 on its inner side at the forward end portion thereof which extends forwardly beyond the end of said triangular, platelike portion, to form a projecting retaining lip or lug 3|, which is engageable in back of the wall section 25. The keylike rib 30 and the projecting lip or lug 3| are of such dimensions as to snugly fit the pocket 24 when the parts are assembled with the lug or lip 3| engaged in back of the wall 25. In the assembled and applied condition of the parts of the lever A, the

platelike portions

22 and 29 together form a forked portion which embraces the bar I5 on opposite sides, which forked portion serves to connect the lever to the bar.

The pivot pin D is in the form of a rivet engaged through aligned openings 32-32 at the lower corners of the

triangular plate portions

22 and 29 and a pivot opening 33 in the bar l5. As will be evident, the pivot pin or rivet D, which serves as a pivotal connection to permit swinging movement of the lever A from horizontal to pendant vertical position, also holds the section C of the lever A interlocked with the section B by holding the keylike rib 30 and its projecting lip or lug portion 3| seated in the pocket 24.

I claim:

In an operating handle lever for a rotary bar,

the combination with an elongated handle member having a longitudinal, laterally offset extension at its inner end, and a pocket in said member at the irmer end thereof adjacent said extension, said pocket having a lateral side wall spaced laterally from said extension, said side wall having a flat transverse end face; of a detachable end section for said member, said end section having a transverse shoulder at its inner end and a laterallyinwardly offset lug projecting beyond said shoulder, said lug being engaged in said pocket and in back of said side wall thereof, and said shoulder abutting the flat transverse end face of said lateralside wall, the end of said end section which carries the lug being in abutment with the inner side of said extension and having an outer end portion parallel to said extension in lateral spaced relation thereto; and a pin extending through said end section, extension and said bar, said pin connecting said handle member to said bar for swinging movement in a plane parallel to the length of said bar, said pin being headed at opposite ends, said heads being shouldered against said end section and extension to hold the same against spreading.
