Application filed April 1,

To all whom it may concern:

Be it known that I, CARLos JUVENTINO OOAMPO, a citizen ofMexico, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Sheet-Metal Fasteners, of which the following is a specification.

This invention relates to a fastener for securing sheet metal panels to a frame work.

It is the object of this invention to pro vide a device which is especially applicable for use in mounting corrugated iron sheets on the roofs and walls of buildings and by means of which the formation of holes or the driving of nails through the sheets may be obviated, and which is of such character as to effect a strong and durable engagement with the sheet that the sheet cannot be readily displaced by the wind.

Another object is to provide a fastener of the type above specified which will permit the metal sheets engaged thereby being removed without injury either to the sheet or fastener.

A further object is to provide a sheet metal fastener which may be readily formed in one piece and economically manufactured. Other objects will appear hereinafter.

The invention is illustrated in the accompanying drawings in which- Figure 1 is a perspective view of the fastener;

Fig. 2 is a view of same in side elevation;

Fig. 3 is a detail in section showing the manner of a plying the fastener in constructing a slieet metal roof on a timber frame;

Fig. 4 is a detail in vertical section showing the manner of constructing a sheet metal wall- Fig. 5 is a view in elevation as seen in the direction of the arrow a in- Fig. 5;

Fig. 6 is a detail in section showing the manner of applying fastener to a metal frame.

In carrying out the preferred embodiment of my invention, I form the fastener from a strip of metal, preferably flat, WhlCh is bent at one end and returned upon itself to form a hook 7 on a straight shank 8- the other end of which is bent at an angle to form a shoulder 9 extending from the side of the shank, opposite that from which the hook projects. The shoulder 9 preferably extends at right angles to the shank and ter- Specification of Letters Patent.

1920. Serial No. 370,459.

Inmates in a prong 10 which projects in the direction of the length of the shaft toward the hook and is adapted to be driven into a timber to effect engagement therewith. An arch 11 is formed at the intersection of the shoulder portion and the prong which extends outwardly relative to the shoulder port1on and one side of which continues into the prong.

In the application and operation of the invention in securing a sheet metal panel to a timber frame, a suitable number of the fasteners are engaged with a horizontal timber 1n the following manner A fastener is placed with the shank 8 seating on and extending transversely of a timber 12 with the hook 7 arranged lowermost and projecting upwardly, whereupon the pron 10 is driven into the upper edge of the timber so that the shoulder 9 will abut thereagalnst, the arched portion 11 ermitting the prong being driven farther into the timber after the shoulder has been brought into close contact therewith.

Where the fasteners are to be secured to I a metal frame the shoulder may be hooked over the beam as shown in Fig. 6.

After mountin the desired number of the fasteners on the lower timber or frame member, a sheet 14 is seated at its lower edge in the upturned hooks and laid upon the frame with its upper end terminating on a spaced parallel frame member. A suitable number of the fasteners are then enga ed with the frame member at the upper en of the sheet and are positioned to lie onv and engage the end of the sheet to hold it in place, whereupon the sheet in the next layer or row of sheets is engaged in the hooks and laid on the frame to form the succeeding course. The shanks in projecting over the upper face of a sheet dispose the hooks beyond the edge thereof so that the lower edges of the superposed sheets 14 will overlap the upper edges of the preceding sheets 14 so as to break joint therewith. In this manner succeeding rows of sheets may be mounted on either a vertical, horizontal or inclined frame, and each plate will be securely anchored at its ends.

Where the fasteners are employed in the construction of roofs the upper ends of the row of sheets adjacent to the ridge terminate a short distance from the latter and are engaged by a series of the fasteners as before described. A strip 15 is then bent at an an 1e and placed astride the ridge and secure in place by engaging its edges in the I claim.

I claim:

A-sheet metal fastener comprising a shank having one end portion bent substantially at a right angle to form a shoulder adjacent the shank and terminating in a prong extending in the direction of the length of the shank parallel thereto; said bent portion being formed with an outwardly extending arch between the shoulder and the base of the prong, the prong being a continuation of one side of the arch and projecting beyond the end of the shank, the other end of said shank being bent and returned upon the shank 0n the side thereof opposite the prong to form a hook.
