4 Claims. (01. 24848.1)

This invention relates to hangers for eaves troughs or the like and more particularly to an improved type of lock for securing the hangers to'the troughs.

An Object of the invention is to provide a new and improved lock adapted to clamp the hangers to the troughs in a simple andpractical manner and to prevent .pressure against the trough from disengaging the locking members and freeing the hanger.

A further object of the invention is to provide anew and improved lock of this type which is particularly applicable to a single strap hanger bowed about the under side and bent backwardly acrossthe open face of the trough with a roof engaging bar extending upwardly therefrom. However, it Will be understood that the invention is not to be limited to a hanger constructed in this manner, inasmuch as its essential features are capable of adaptation to other types of hangers.

It will be noted that the improved type of lock involves essentially integrally formed locking members which do not require additional members or parts. Moreover, it will be noted that these locking members inter-engage to hold the parts securely together and cannot be inadvertently freed of each other by the weight of a ladder or other pressure against the trough or hanger. The'bowed portionis preferably provided with a slot adjacent the juncture with the roof engaging bar for receiving a hooked tongue struck up from the opposite free end, while the roof engaging bar is-provided with a slot into which the hooked tongue thereafter extends for providing an interlocking engagement that cannot be accidentally released.

This typeof lockis inexpensive and exceedinglysimple tooperate. 'Its action is positive and assures a proper locking relation between the parts each time it is operated. It does not require additional parts which merely add to the cost of manufacture and which hamper the quick and positiveactionquite essential for devices of this kind.

Other objects and advantages of the invention willbe apparent from the following detailed description when taken in connection with the accompanying drawing.

In the drawing:

-Figure 1 is a perspective view of'a hanger embodying the present invention and illustrating the-locking members secured together;

Fig. 2 is a similar view of this hanger, illustrating how the locking member of one part is brought into engagement with the other part;

'Fig. 3 illustrates the manner in which the hanger supports a trough at the edge of a roof;

Fig. 4 illustrates this hanger in the form in which it is made and shipped but before it is shaped about the trough;

Fig. 5 is an enlarged detail view of the lock shown in the preceding figures;

Fig. 6 is a View similar to Fig. 5, but illustrating an alternative embodiment of the invention;

Fig. '7 is likewise a similar view, butillustrating a further alternative embodiment of the invention; and

Figs. 8 and 9 illustrate still further modified formsof lock embodying the invention.

The single strap type of hanger, illustrated herein as a preferred form of hanger to which my invention is applied, comprises, as is generally known, a trough engaging portion .2 adapted to be shaped to the under side of the trough at the time the hanger is applied. Also, a roof engaging bar 3 is provided that may be adapted to the roof at the time of installation by bending the same at 4 so as to compensate for the pitch of the roof and the manner, in which the trough is to be suspended at the eaves. The outer edge 5 of the trough 6, as shown in Fig. 3, is generally varyingly formed according to the type of trough used; consequently, the outer edge of the trough engaging portion 2 is formed at I to fit over outer edge 5 of trough 6. I have illustrated a rolled outer edge 5 on trough 6, and consequently, a curled portion 1 which will embrace the curled edge 5. Curled portion I has the further function of lending resiliency to the intermediate leg 8 from which roof engaging bar 3 is bent upwardly. The inner edge of trough 6 may be differently formed, say with a sharp upstanding edge 0. Accordingly, the opposite end of trough engaging portion2 is crimped as indicated at H] to receive inner trough edge 9. This end of the hanger continues across the open face of trough .6 in the form of a leg H.

The hanger is generally manufactured and shipped in the form shown in Fig. 4. It will be noted in this figure that the trough engaging portion 2 is flat so that it may be shapedto the under side of the trough at thetime'the hanger is mounted. This will bring legs 8 and II across the open face of trough 6, as illustrated in Fig. 3.

Leg 8 overlaps the free end of leg M in order to provide a positive and simple lock for the free end of'leg l I, which will engage leg 8. A slot I2 is formed in leg 8 by striking up lip 13. The

free end of leg II is likewise slotted at I4 by striking up tongue I 5 having a hooked end I6.

Hooked end I6 is bent at right angles to tongue I6 enters slot I'I. Lip l3 will then positively hold tongue I5 against bar 3 and keep hooked end I6 in slot II. This locking device is exceedingly simple, inexpensive to make, and requires no additional parts. It is easy to operate, because tongue I5 may be easily inserted in slot I2 by pulling legs 3 and I I together so that hooked end I6 may freely enter slot IT. The tension of the material will quickly pull the hooked end I6 through slot I1 and bring tongue I5 against bar 3. The advantage of a simple lock of this type which does not require additional parts will be readily appreciated in view of the hazardous positions required of tinsmiths in hanging troughs along the edges of the roof.

A snap action is provided which makes the device self-locking after tongue I5 is inserted through slot I2 and hooked end I6 enters slot II. A slight pressure against lip I3 will bend it downwardly to engage against tongue I5 as illustrated in Fig. 5. The use of lip l3 for this purpose is not essential.

An alternative embodiment of the invention is illustrated in Fig. 6. The end of leg II may have a tongue I8 formed thereon which enters a slot I9 in leg 8. Slot I9 may be formed to the rear of slot I2 and lip I3 may be omitted. The strap metal construction of the hanger permits the provision of these tongues and slots by a single stamping operation, and consequently, they may be accurately positioned so that the tongues will readily enter the slots and hook into position. The same is true in connection with the form of lock shown in Fig. 5.

In the alternative embodiment shown in Fig. 7, the free end of leg II is formed with a pair of of

upstanding tongues

20 and 2| entering corresponding grooves 22 cut in the edge of leg 8.

Tongues

20 and 2|, engaging in grooves 22, likewise prevent disengagementof hooked end I6 from slot I! when any pressure is applied tending to increase the bowing of trough engaging portion 2 so as to buckle legs 8 and II inwardly.

The same result may be obtained by stepping down leg 8 as illustrated at 23, soas to provide an abutting wall 24 against which the edge of leg I I may rest as illustrated in Fig. 8.

If so desired, a tongue 25 may be punched out in the formation of slot l2, as shown in Fig. 9, so as to extend forwardly of leg 8 and engage in a slot 26 formed in leg I I. In this form of the device, tongue l5 will likewise pass through slot l2, as shown in the preceding views, and the hooked end l6 may enter slot I'I. Inward buckling of leg members 8 and II, tending to free hooked end Hi from slot I1, is likewise efiectively prevented by tongue 25 entering slot 26.

It will be apparent from the foregoing descriptionthat my invention is directed particularly to a novel arrangement of interlocking members between legs 8 and II of the hanger, which interlocking members may be formed in one operation during the making of the hanger and which do not require any additional parts. The interlocking members are simple and effective, and because of the resiliency of the strap metal of which the hanger is made, legs 8 and Il may be easily manipulated tobring these interlocking members into proper locking relation so as to effectively secure a locking of the parts that cannot be accidentally disturbed.

It will be apparent that the tongue and groove interlocking members shown herein may be applied in different ways to the hangers and also embodied in hangers of difierent construction than that shown in the drawing.

Withoutfurther elaboration, the foregoing will so fully explain the gist of my invention that I others may, by applying current knowledge, readily adopt the same for use under varying conditions of service, without eliminating certain features, which may properly be said to constitute,

the essential items of novelty involved, which items are intended to be defined and secured to me by the following claims.
