Aug. 15, 1939 J. J. FANNING LUGGAGE LATCH DEVICE Filed Nov. 13, 1937 Patented Aug. 15, 1939 UNITED STATES PATENT OFFICE John J. Fanning, Brooklyn, N; Y. Application November 13, 1937, Serial No. 174,279

4 Claims.

This invention relates to improvements in latch devices and more specifically to a friction latch device for use upon suit cases, trunks, and other like articles of luggage.

One of the features of the invention resides in a latch device for securely holding the two sections of a suit case or other like article of luggage in closed position regardless of the outward pressure exerted upon the sections caused by overpacking of the suitcases Another feature of the invention is to provide a latch'device which will enable the two hinged sections of a suitcase to be brought into locked relation prior to the full closing of the sections and which sections may be gradually forced to fully closed latch position against any outward restraining pressure which may be caused by the overpacking of the suitcase.

A further feature is the pro-vision of a latch device for suitcases which functions to initially latch the two hinged sections of a suitcase preparatory to the full closing of the same, and subsequently functions to guide the hinged sections to fully alined closed position to prevent relative shifting of the sections which relieves the hinge connection of undue strain.

A still further'feature of the invention is to provide a friction latch device which is simple and inexpensive of construction, positive in its latching function, easy to manipulate to unlatching position, and which does not detract from the appearance of an article of luggage when in use thereon. g

- With these and other objects in view, the invention relates in the novel features of construction, combination and arrangement of parts, the essential features of which are hereinafter fully described in the specification, are particularly pointed out in the appended claims, and are illustrated in the accompanying drawing, in which:

Figure l is a perspective view of a suitcase or traveling bag in open position with my improved latch device in use thereon, the latch bolt being shown in inoperative position in dotted lines, and in operative position in full lines.

Figure 2. is anend elevational view of a suitcase with the cover partially closed and the latch device in its initial latching position.

Figure 3 is an enlarged fragmentary vertical sectional view illustrating the sections of the suitcase in fully closed position.

Figure 4 is a fragmentary vertical sectional view on the line 4-4 of Figure 3. v

Figure 5 is a detail horizontal sectional view on the line 5-5 of Figure 3.

Referring to the drawing by reference characters, the numeral i0 designates a suitcase or other like article of luggage which includes a body section H and a cover section 12, the said sections being hingedly connected along one of their edges as at I3. Whereas two of my latch devices 1 have been illustrated in Figure 1 uponv the suitcase ill, a description ofone will 'suffice for the other.

My improved latch device includes a keeper face plate I5, riveted or otherwise secured to the top wall of the body section H and which plate overlies a slot It provided in the-said wall and which slot has opposed outwardly converging walls I l for a purpose to be presently appreciated.

The plate I5 is also provided'with a slot It, the v opposed longitudinal walls of which" act as fulcrums for the latch plate to be'presently described. Riveted or otherwise secure-d to the face plate and extending outwardly therefrom is a box-like housing I9 which receives the tail end of a friction latch plate 2|, the head end of the said plate being designated 22 and extending within the body section II. 'The head end 22 of the latch plate is provided with a bolt receiving opening 23." The, latch plate 2! extends through the slots l6 and I8 and is prevented from becoming separated from the housing H! by reason of the outwardly extending lugs 24-24 disposed at opposite sides of the latch plate and engaging the outer side of the face plate l5.

Pivotally supported by the housing I!) is an actuating lever 25', the same being of substantially U-shape with the terminal ends bent inwardly and journaled in opposite sides. of the housing I9, the said terminalends'being semicircular orcam shaped in cross section as at 26. The flat surfaces of'the cam portions 26 act as. stops or rests for the tail end 20 of the latch plate 2| and interposed between the tail end of the latch plate and the adjacent wall of the housing I!) is an expansion spring 21, which spring acts 'to impart a tilting or canting action to the latch plate 2!, the canting movement being limited by the cam portions 26 of he lever .25. The lever 25 remains in the position shown in Figure 3 of the drawing at all times except when it is desired to impart a releasing movement to the latch plate 2|, at which time the lever 25 is swung outwardly causing the cam portions 26 to act upon the tail end of the latch plate and correspondingly move the head end of the latch plate to releasing position.

Coacting with each of the keeper elements I4 is a latch bolt 28 which has its inner end pivoted at 29 to a bracket 30, the said bracket being fixedly attached to the top wall of the cover section [2, by rivets or other like fastening means 3|. The bracket 30 is provided with bolt receiving seats 32 and 33-33, there being resilient segmental shaped surfaces 34 intermediate the seats 33 and 32 and over which the bolt 28 may be swung when it is desired to move the same to either an operative or inoperative position. When the bolt 28 is swung so as to seat upon the seat 32 as shown in full lines in Figure 4, the said bolt is in operative position to be received in the opening 23 of the latch plate 2|, but when the bolt 28 is swung into either of the seats 33, the same is held parallel to the top wall of the cover section so as to be disposed in an out-of-theway position. The free end of the bolt 28 is pointed or rounded as at 35 so as to more readily enter the opening 23 in the latch plate when these two parts are brought into operative engagement with each other.

Secured to the front wall of the body section H is a substantially U-shaped shield member 36, the same having flanges 31 which fit against the said wall and through which rivets or other like fastening elements 38 pass. The shield member 36 acts to prevent any obstruction such as articles packed in the body section M from coming into the path of the bolt 38 during a latching operation.

Assume that the suitcase I0 is in an open position as shown in Figure 1 of the drawing, and the cover I2 is swung to a position over the body section II. Prior to the full closing of the cover section l2, the bolt 28 enters the opening 23 in the latch plate 2| as illustrated in Figure 2 of the drawing, and as the bolt enters the opening, the walls of the same become jammed and prevent any withdrawal of the bolt from the opening due to the angularity of the latch plate with respect to the axis of the bolt. The bolt 28 however may be freely pushed inward and during its gradual inward movement, the latch plate still acts to prevent withdrawal of the bolt. Thus it will be seen that if the body section II of the bag It) is overpacked, the cover section |2 may be initially latched as shown in Figure 2, and subsequently forced to fully closed position as shown in Figure 3, and at which time the free end of the bolt enters the shielded space provided by the shield member.36. Assume that it is desired to open the cover section l2, whereupon an operator grasps the actuating lever 25 and pulls outwardly thereon to cause the cam portions 26 to move the latch plate 2| to a position substantially at a right angle to the axis of the bolt 28. When the latch plate 2| has been so moved, the cover section l2 may be opened, for the bolt 28 is free to slide through the opening 23. After actuating the lever 25 to released position and the swinging of the cover section |2 to open position the lever 25 may be returned to its original position to again permit the spring 2'! to move the latch plate 2| to its latching position.

While I have shown and described what I consider to be the most practical embodiment of my invention, I wish it to be understood that such changes and alterations as come within the scope of the appended claims may be resorted to if desired.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent of the United States, is:
