F. EUBANKS KEY GUIDE Filed May 6, 1925' Patented July 20, 1926.

FLOYD EUBANKS, OF PASADENA, CALIFORNIA, ASSIGNOR F ONE-HALF TO ROBERT E. MCCOLLOR, 0F PASADENA, CALIFORNIA.

Application filed May 6,

My invention relates to attachments for door locks and more particularly to a guide for guiding the key into the keyhole of the lock.

It is an object of the invention to prov de a key guide'formed from a single piece of resilient metal which may be easily and securely attached to the keyhole without the. necessity of making alterations.

A further object of the invention is to provide a device of the above-mentioned character which is simple and durable in construction, eflicient in use and. inexpensive to manufacture.

Other objects and advantages of the invention will be apparent during the course of the following description.

1 In the accompanying drawing, forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

' Fig. 1, is a fragmentary perspective view of a door and lock with my invention applied thereto,

Fig. 2, is a perspective view of the guide, Fig. 3, is a longitudinal sectional view of the guide applied ,to the escutcheon plate, and,

Fig. 4, is aplan view showing the blank from which the guide is formed.

In the drawing, wherein for the purpose of illustration I have showna preferred em- I bodiment of my invention, the numeral 5 designates an escutcheon plate of a conven- ',ti.onal type of door lock having the usual ,keyhole opening 6 to which my guide is at- ,tached. The guide is denoted in general by the numeral 7 being formed from a longitudinal strip of sheet metal 8 bent intermediate ts ends, to form a substantially V- shaped body, the ends of which are tapered and slightly curved upwardly, as at 9. An upwardly curved tang 10 extends laterally from one edge of the body at its apex and is adapted to engage the peripheral edge of The sides of the the keyhole6at the top. h k hl b h to eyoe yte body are connected wit KEY GUIDE.

arms 11 formed integral with the same edge and" bent inwardly, at right angles to the sides, towards each other, having their free extremities curved to form hooks 12 adapted to engage the peripheral edges of the keyhole at the sides. The body is formed of spring metal, so that the tension of the sides will hold the arms 11 in engagement, with the keyhole, but may be easily compressed to release the arms when removing or aflixing the guide in place. It will be observed that the body on each side of the arms and tang are slightly notched, as at 13, so that when ,the arms are bent the body will lie flush with the surface of the escutcheon plate.

As more clearly shown in Fig. 4, the guide is formed from a single piece of material, the arms '11 extending from one edge of the strip at an angle, so that when the strip is bent into proper shape thearms will be disposed on a horizontal plane, whereby the resiliency of the sides will hold the arms in firm engagement with the keyhole.

In use, it will be seen that ake hole -equipped with the'guide may be easily ound in the dark, since the key upon contacting Iwiph the guide will be guided into the key- It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example or the same and that certain changes in the shape, size and arrangement of the parts may be .niade without departing from the s irit of the invention within the scope of t e subjoined claims.

Having thus described my invention, I claim:

1. A key guide comprising a V-shaped body formed from a single strip of resilient metal, and arms extending inwardly from the sides of said body movable, through the resiliency of the body to engage an opening for connecting said body thereto.

2. The combination with an escutcheou plate having a keyhole opening, of a V- shaped body formed from a single strip of pansible V-shaped body, and arms extending inwardly from the sides of said body, adapt- 30 ed to be held in engagement with said opening through the expansion of said body.

t n testimony whereof I affix my signaure.

FLOYD EUBANKS.
