SECURING MEANS FOR THE COVERS OF DISPLAY-PACKAGES.

Specification of Letters Patent.

Patented Dec. 19, 1916.

Application filed May 7, 1915. Serial No. 26,550.

To all whom it may concern:

Be it known that I, THEODORE J. ABELE, citizen of the United States, residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Securing Means for the Covers of Display-Packages; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which is appertains to make and use the same.

This invention relates to means for securing a transparent plate to the lid or cover of a display package.

The object of the invention is to provide a very simple, cheap and eflicient fastening device for holding a transparent plate upon the opening of the cover of a display packa e.

Another object is to provide a fastening device for the purpose mentioned which can be easily and quickly placed in position or removed to release the said plate.

In order to make the invention clearly understood, I have provided the accompanying drawing, in which,

Figure 1 is a plan of the inner side of a display cover showing a transparent plate and fastening device therefor forming the subject of my invention. Fig. 2 is a sectional elevation of the same 'shown in its inverted position. Fig. 3 is a sectional elevation of a portion of the cover and its transparent plate showing the invention on a much larger scale than in the first two figures; and, Fig. 4 shows the invention in perspective mounted upon part of a lid illustrating the manner of engaging the transparent plate.

A represents a lid or cover for a box, barrel, or other form of package, and provided with a central opening B through which the contents of the package covered by the lid may be observed, and G represents the transparent plate or glass plate covering said opening.

D indicates a series of U-shaped members soldered or otherwise secured to the inner surface of the lid or cover, the same bein spaced from one another substantially as shown. They are also spaced from the opening B a sufficient distance to permit the transparent plate C to lie upon said inner surface of the lid or cover. Said members D are preferably extended slightly below the will just slip over lower surface of the said transparent plate as shown in F ig. 3 in which the lid or cover is inverted, though the extent of projection of the member is not highly important.

E indicates a strip of thin sheet metal such as steel, or spring brass, having one of its extremities recurved upon itself as indicated at F, the same being slightly bent away from the body of the strip as shown in the figure last referred to leaving a gradually widening space between it and said body, and secured to the latter by a rivet E. The opposite end of the strip E is bent substantially at right angles into the part G or-at a slightly acute angle to the bod thereof. The strip thus formed constitutes the fastening device for the transparent plate, its end having the recurved portion F adapted to rest upon and firmly engage the margin of the plate and hold it upon the cover A. As shown, the said portion F is adapted to engage beneath the U-shaped member, the latter lying between said portion and the body portion E, the rivet forming a stop or abutment for said member D. The width of the part D is such that when the strip is forced upon it as described and the rivet lies against one edge, the part G and snap upon and lock with the opposite edge of said member D, engaging beneath it in such a way that the strip will be firmly and securely held regardless of the weight of the transparent plate upon it when inverted upon the pack age, and regardless of any heavy pressure or jars or blows of the most severe nature. The reason for this secure holding of the plate is that the recurved extension F acts as a fulcrum upon the inner surface or corner of the member D. Pressure, therefore, upon the lever formed outward from the said member by the extension of the strip E and its recurved portion forces the opposite end having the part G, down upon the said member D, the recurved portion being unable, of course, to leave the latter.

The material of the spring strip is preferably quite stiff so it is required that the g .part G in order to be locked behind said member D must be given a strong sharp pressure to lock it in place so that its firm position is assured. Other means equivalent to the member D may be provided for re ceiving the spring strip E such as will accomplish the desired result since it is not FFTQE,

FLEXIBLE PIPE JOINT OR COUPLING.

Application filed June 20, 1913.

To all whom it may concern: Q

Be it known that I, EZRA C1 ALE, acitizen of the United States, residing at Tyrone, in the county of Blair and State of Pennsylvania, have invented certain new and useful Improvements in Flexible Pipe Joints or Couplings, of which the following is a specification.

My invention relates to flexible pipe joints or couplings for use in connection with railway air brake systems.

The prime object of this invention is to provide a strong, durable, economical and efficient device designed to enable the con nected parts to move freely one relatively to the other, and at the same time preventing the escape of the fluid passing through them.

Another object of the invention is to furnish a device constructed of such material as will safely withstand the considerable pressure under which the air is passed through the pipes, thus preventing accidents and loss of life sometimes occasioned by the bursting of the air hose made of rubber and fabric and commonly employed in air brake systems, and has special reference to pipe installations on railway trains, where the connected parts are subjected to frequent relative movements.

The foregoing and such other objects as may occur from the ensuing description are attained by the combination and arrangement of parts hereinafter more fully described, and particularly set forth in the claim appended hereto, and illustrated in the accompanying drawings, in which 2- Figure 1, is a view partly in plan and partly in perspective showing the device embodying my invention. Fig. 2, is a longitudinal sectional view of my improved flexible joint, and Fig. 3, is a plan view showing the parts constituting one of the members detached from its connection.

Similar characters of reference indicate like parts in all the figures of the drawing.

The several parts employed in carrying out my invention are made of any suitable metal best adapted to withstand the air pressure to which the parts are necessarily subjected, and consist of the sections or members A and B, each of said sections or members being movably connected to a hollow central member or casting O.

The section or member A is composed of two hollow metallic pipe castings 1 and 1 Specification of Letters Patent.

each being curved inward and terminating at its outer end with a straight extension 2, the inner face of each extension being made to contact with each other and tightly secured together by a sleeve or band 3, or in any suitable manner, while the inner end of each of said castings terminates in a lateral or inward extension 5 adapted to be rotatably connected to the lateral extensions 5' forming a part of said central member C. The section or member B of my improved flexible joint is likewise constructed of castings 6 and 6 in all respects like the section A, and the inner end of each of said castings 6 and 6 are fitted to lateral extensions on member C formed at right angle and adj acent to the said extensions 5. The central member 0 consists of a single casting comprising, a hollow central hub portion 7 provided with shoulders 4., said hub portion having reduced hollow integral lateral extensions 5 projecting from either side thereof, and also reduced hollow integral lateral extensions projecting from either side of said hub portion adjacent to and at right angles to the said extensions 5, the inward lateral extensions of each member A and B being adapted to abut against and rest in contact with the said shoulders 4 formed on the hub. The metallic pipe castings 1,1, and 6, 6 are each curved inward and terminate at each outer end with a straight extension 2, and by placing them together an inlet passage 8 is formed in member A, and an outlet passage 12 is formed in member B.

It will readily be seen that air or fluid passing into the opening 8 in section A will pass around through the openings in 1 and 1 and into the opening 9 in the central member, and from thence through the cross opening 10, and thence through the openings 11 formed in the castings 6 and 6 and out through opening 12 in section B, at whatever angle the sections A and B may be placed with respect to each other.

It will be readily perceived that by connecting the sections to the central member in the manner herein described and as illustrated in the drawings the said sections will move freely one relatively to the other to -the right or left, or in an upward or downward direction.

It will be obvious that my improved flexible coupling may be connected in any suitable manner to the train pipe system, and that any old and well known type of car
