MANTLE LID FASTENER March 15, 1955 A. CLAUD- 2 Sheets-Sheet 1 Filed Feb. 5, 1952 INVENTQR M W 4; 3' JZiMr ATTORNEYS United States Patent LID FASTENER Arthur Claud-Mantle, Trumbull, Conn., assignor to The Bassick Company, Bridgeport, Conn., a corporation of Connecticut Application February 5, 1952, Serial No. 270,057
Claims. (Cl. 292-113) This invention relates to lid fasteners of the kind employed for fastening the lids of boxes and similar containers, and relates to the type in which one member is secured to the lid of a box and another member is secured to the box body. It relates more particularly to a fastener comprising a lid-attached retainer having a spring-pressed latching member, and a box-attached toggle member adapted to cooperate with the spring-pressed latching member to fasten the box lid.
One of the objects of the invention is to provide an improved lid-attached retainer.
Another object is to provide a lid-attached retainer having a spring-pressed latching member.
Another object is to provide a lid-attached retainer having a latching member downwardly displaceable against spring pressure to permit a gasket or packing member to be disposed between the box body and the box lid to provide an air-tight and water-tight connection between the aforementioned box parts.

In the drawings, each form of my invention selected for illustration comprises a retainer adapted to be secured to the lid of a box, and an over-center toggle adapted to be secured to a box body. The retainer comprises a spring-urged latching member cooperating with the toggle to exert a resilient downward pull on the box lid. The toggle, in turn, comprises a catch member cooperating with the latching member of the lid-attached retainer, and also comprises an operating or manipulating lever. In the'form of the invention shown in Figs. 1 through 9, the catch member comprises a leaf spring having a hook formed at the upper end thereof engageable with the latching member of the lid-attached retainer through a slot formed therein. In the form of the invention shown in Figs. 10 through 12, the catch member comprises a wire bail engageable with a lip formed on the lower portion of the latching member of the lid-attached retainer.
2 2,704,218 Patented Mar. 15, 1955 In Figs. 1 through 9, the box body is indicated at 10, the lid at 11, the retainer applied to the lid at 12, the latching member carried by the retainer at 13, the slot in the latching member at 14, the catch member comprising a leaf spring at 15, the hook at the upper end of the leaf spring at 16, and the operating lever at 17.
The operating lever 17 of the toggle is constructed of sheet metal and has a substantially planar surface 18 and side flanges providing spaced parallel walls 19 extending outwardly and upwardly to form a bifurcated structure. The lower end of the operating lever 17 is arcuately bent to provide a finger grip portion 20.
The operating lever 17 is supported from an attaching plate 21 adapted to abut the box body 10 and provided with perforations to receive box-attaching screws or bolts 22. The attaching plate 21, constructed of sheet metal, is generally of inverted U shape and is provided with a pair of outwardly directed perforated cars 23 straddling the upper ends of the side walls 19 of the operating lever. The upper ends of the walls 19 of the operating lever are perforated to receive a pivot pin 24 extending between and carried by the ears 23 and pivoting the operating lever to the attaching plate.
Intermediate the ends of the operating lever 17, the lever 17 is provided with an over-center pivot comprising a pin 25 extending between and carried by the walls 19 adjacent their inner edges. The leaf-spring catch member 15 is constructed of sheet metal and has its lower end 26 bent over the pivot pin 25 so as to be pivotally connected to the operating lever 17. The hook 16 is provided at the other end of the catch member 15, and the intermediate portion 27 of the catch member is bowed outwardly.
The retainer 12 comprises a bracket or casing 28, formed of sheet metal, having a planar forward face portion 29, and having rearwardly directed flanges comprising side walls 30, a top wall 31 and a bottom wall 32. The bottom wall is provided with an inner depending projection 32 to abut the box lid. Each of theside walls 30 is provided with a lug 33 at the lower extremity thereof underlying the bottom wall 32 to prevent downward displacement of the latter, and each of the side walls 30 is provided with an ear 34 adapted to abut the box lid, each car 34 being perforated to receive -lidattaching screws or bolts 35.
The bracket 28 provides a support for the depending latching member 13 in a manner to be explained hereinafter. The latching member 13, constructed of sheet metal, is provided with a wedge-shaped lower portion 36 slotted at 14 to receive the hook 16 of the catch member 15. The latching member 13 is provided with a plurality of fingers 37, four being preferred, extending upwardly from the wedge-shaped lower portion 36. Each of the fingers 37 is preferably twisted on its longitudinal axis. The fingers 37 are provided with horizontally aligned holes 38 to receive a spring-retaining pin 39, the function of the latter appearing, hereinafter. The fingers 37 are received within the bracket 28 through circular holes 40 in the bottom wall 32, and the distal ends of the fingers are engageable with the under surface of the top wall 31. A helical spring 41 is slipped over each of the fingers 37 to engage the upper surface of the bottom wall 32, and the spring-retaining pin 39 is inserted in the holes 38 in the fingers 37 over and across the upper ends of the springs 41. The springs 41 are under compression when the outer ends of the fingers 37 are engaged by the top wall 31 of the bracket acting as an upper stop for the latching member. In the assembled retainer, the arrangement is such that the springs 41 are constantly under compression between the bottom wall 32 of the bracket 28 and the spring-retaining pin 39, the springs 41 constantly exerting a resilient upward pressure upon the slidable latching member 13.
To fasten the lid of the box, the toggle is swung up wardly toward the retainer and the hook 16 of the catch member 15 inserted in the slot 14 of the latching member or slide 13 to engage the latter, the fastener then being in an intermediate position, shown in Fig. 3, for example.
moving the latching member 13 downwardly against the pressure of springs 41 until the lower pivot 25 carried by the operating lever 17 and pivoting the lower end of the catch member 15 passes dead center, at which point the pivot 25 is urged upwardlv and inwardly toward the box bv the s rings 41, which are then strongly compressed. and the fastener is closed and assumes the positron shown m Fig. 2. In the last-mentioned position, the action of springs 41 is such that outward swinging movement of the operating lever 17 is stron ly resisted, the springs 41 effectivelv preventing acci ental disl catron of the toggle. In the closed position. the fastener exerts a stron downward pull on the box lid throu h the catch member 15. the latching member 13, the springs 41. and the bottom Wall 32 of the bracket 28.
With particular reference to the retainer 12 and parts thereof. it 15 to be noted that, as the to le is moved from the intermediate position shown in Fig. 3 to the closed position shown in Fig. 2. the catch member 15 displaces the latching member 13 with respect to the box lid and the bracket 28. the latching member moving downwardly a ainst increasing compression of the sprin s 41 interposed between the pin 39 carried by the lat h n member and the bottom all 32 of the bracket 28. Normally. m the closed position of the fastener. the s ri gs 41 are not fullv compressed: h ever. such mav be the case and. when this occurs. it will be underst od that the COIlS of the sprin s 41 and the retaining pin 39 a t as stops limi ing downward movement of the latching member 13. i
As the catch member can convenientlv take the f rm of art outwardlv bowed le f sprin as shown. bei g un er tension in the cl sed posi ion of the f stener. the latter adds to the resiliencv of the connection between the tog le and the retainer.
A s previouslv stated. when the fastener is in the cl sed position. opening movement of the o erating lever 17 is resisted bv the springs 41 as the sprin s 41 are fur her com ressed as the o erating lever is swung outwardlv to the point where the ivot in 25 at the lower end of the catch mem er pa ses dead center. and t t s point the s rings 41 ur e he operating lever 17 unwardlv and outwardlv from the box and the t ggle is moved to the intermediate position shown in "Fi 3. Q
As the le is opened and mr ed from the Ositifln shown in Fig. 2 to that sho n in Fi 3. the h k 16 of the atch member 5 is re ined within the slot 14 of the lat hing mem er 13 so th t the book 16 will not fly back to possiblv strike and ininre the h nd of the one ator. As the to le is opened. th hook end of the at h member moves unwardlv and inwardlv throu h the s t i the latching member, owing in part to the how shape of the catch member. and when al owed to dro back. reen a es the latching member. When the to le is in the intermediate osition. the catch member is easil di ngaged from the latching member bv gras in the fir member and lifting the hook out of the slot in the second member.
In the modified form of mv invention shown in Fi s. 10. 11 and 12, the lidttached retainer 12 is en r lv similar to the retainer 12 previouslv described. The l tching member 13" is not s otted at its lower portion but s provided with a bottom flange formin an upturned b engagin lip 42. The catch member 15 is sho n as a wire bail bowed outwardly at 44 and having its ends pivotallv connected to an operating lever 17 The ope ating lever 17 constructed of sheet metal, is shown in the form of a voice having a planar outer surface 45 and an outwardly inclined flange 46 at the lower end thereof. A pair of laterally spaced box-engaging proiections 47 extend inwardly from the flan e 46 of the lever 17'- to limit the swing of the lever 17 toward the box, and permit access of the operators fingers between the box and the lever portion 46 to open the toggle. A pair of laterally spaced lugs 48 extend inwardly from the upper portion of the lever 17 and are pivoted to a boxattaching bracket 21, similar to the box-attaching bracket 21 previously described. The lugs 48 are pivoted by a pivot pin 24 carried by and extending between ears 23 of the bracket 21, the lugs 48 being straddled by the cars 23. A distance below and inwardly from the pivot pin 24', each of the lugs 48 is pivotally connected as at 49 to one of the ends of the wire bail.
From the foregoing, the operation of the lid fastener shown in Figs. 10. 11 and 12 will be evident, and it will be understood that this fastener functions in substantially the same manner as the fastener shown in Figs. 1 through 9 and previously described.
In each of the preferred forms of my invention described herein there is provided a retainer having great strength. The bracket is strongly supported from the box lid owing to the manner in which flanges of the bracket abut the lid and are secured thereto. The bracket has a narrow profile so that it extends outwardly from the lid a short distance only. It is also to be noted that the bracket affords the latching member and associated springs a large measure of protection owing to the wall structure of the bracket, which is imperforate with the exception of the bottom wall thereof. As previously mentioned, the bottom wall of the bracket is strongly supported from beneath by the aforementioned lugs at the lower extremities of the side walls of the bracket.
The springs associated with the latching member of the retainer are sufficiently heavy to exert a strong pressure on the bottom wall of the bracket when the retainer is inoperative, the fingers of the latching member being in strong engagement with the top wall of the bracket. It will be understood that, when the retainer is operative to fasten the lid of the box, the springs associated with the latching member are further compressed and exert a stronger pressure upon the member and the bottom wall of the bracket. In this connection, it is to be noted that the fingers of the latching member have great strength owing to the fact that they are twisted on their longitudinal axes.
A distinct advantage of my improved lid fastener is owed to the fact that the spring-urged latching member has a substantially rectilinear movement and is carried by a part in fixed relationship to one of the box parts, such provision facilitating closing of the fastener against strong spring pressure. It is also to be noted that, with this provision, a lost motion and consequently loose connection between the catch member and the operating lever is not required.
Another advantage of my improved lid fastener is attributable to the fact that the latching member is displaceable downwardly against a considerable degree of spring pressure, permitting a gasket or packing member to be disposed between the box body and the box lid to provide an air-tight and water-tight connection between the aforementioned box parts.
My improved lid fastener is comprised of few and simple parts having great durability, and can be produced at low cost.
The illustrated constructions are by way of example only, and various changes in the organization of parts and in details may be made without departure from the principles of the invention or the scope of the claims.
