TRU N-K-LOCK...

SPECIFICATION forming part of'Letters Patent No. 521,471, dated June 19, 1894.

Application filed November 3, 1893. Serial No. 189,912. (No model.)

To aZZ whom it may concern.-

Be it known that L'EDWARD A. J UDD, a citi zen of the United States, residing at New Britam, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Hasp Locks and 1(guards, of which the following is a specificaion.

My invention relates to improvements in IO hasp locks and guards, and the objects'of my lmprovement are simplicity and economy in construction and particularlyto produce the hasp plate and guard of sheet metal, whereby an efficient and neat appearing lock is pro- I 5 duced at a small cost.

t In the accompanying drawings: Figure 1 is a front elevation of my lock complete. Fig. 2 1s a central vertical section of the same with the lower part of the hasp in elevation. Fig. 3 1s a rear elevation of the hasp plate and hasp. Fig. 4 is a front elevation of the guard -and keeper. Fig. 5 is a plan view of the blank from which said guard and keeper is struck up. I Fig. 6 is a front view showing the 2 5 result of the first operation upon the blank, Fig. 5. Fig. 7 is a plan view of the blank for the hasp plate. Fig. 8 is a front elevation of the result of the first operation upon said blank, and Fig.9 is a like view showing the result of the second operation.

A designates the hasp having secured thereto, or built within it, a lock of any ordinary construction with the lock bolt 10 arranged to be extended outwardly from itslower end.

As s usual with this class of locks, the hasp is also provided with a spring 11, one end of which presses upon the'cross bar 12 of the hasp plate B with a constant tendency to force the hasp outwardly when released. The hasp plate B is struck up from a sheet metal blank, Fig. 7, in suitable dies by one or more operations, resulting in the form shown in Fig. 9. The surplus metal is then removed from its edge. This hasp plate is formed with a bead 16 which is substantially in the form of an inverted U in front elevation with the dowel pins 13 formed at the ends of said bead as best shown in Fig. 3. The space inclosed by this bead is to receive the upper end 5'0 of the hasp A. A portion of the hasp plate above the cross bar 12 is removed for convenience in assembling the parts, and the inner wall of the bead by the sides of this opening is recessed to receive the pintle 14 of the hasp, as shown in Fig. 3. In order to prevent the hasp from becoming accidentally detached during transportation, the plate 15 is secured. by means of a rivet upon the inside of the bead so as to cover the ends of the pintle 14 and hold it in place. While I prefer to make the dowel pins in one and the same piece with the hasp plate, it is evident that they may be separably formed and rigidly secured thereto if desired.

I form the guard and keeper from a plate of sheet metal as shown in Fig. 5, the same being struck up to form the U shaped bead 17 with the space inclosed by said bead of a suitable form to receive and hold the lower end of the hasp as shown in Figs. 1 and 2, the upper ends of the bead being widened to form inwardly projecting shoulders for being.

engaged by the'widened lower end of the hasp A. It is best to strike this blank first into the form shown in Fig. 6 and then again strike it to flatten the flange outside of said bead,

after which its edges may be trimmed and the central part punched out, thereby changing the metal from the form shown in Fig. 6 to that shown in Fig. 4. In the inner wall at the lower part of this bead 17, I form a slot or mortise 18 as shown in Fig. 2 to receive the end of the lock bolt 10 and enable this part of the lock to serve as a keeper for said bolt. The upper ends of the bead 17 are left open to form sockets 18 for the reception of the dowel pins 13. This guard or keeper protects the lower part of the hasp and its look from injury by a continuous bead around it, preferably with a slight flange upon its outer and inner edges. Locks of this general class having acombined guard and keeper with the lock attached to the hasp and also provided with a dowel system are old when the hasp plate and combined guard and keeper are formed of cast metal, and I hereby disclaim the same.

By my improvements I form the hasp plate with its cross bar 12 in the same piece with the other parts andIam enabled to form the same cheaply by striking it up from sheet metal. I also form the guard and keeper by IOO striking it up from sheet metal,and by these improvements I economize in labor and neoessarily modify the form and construction of the parts whereby I produce a neat and efficient lock of this class.

I claim as my invention- 1. The herein described hasp lock, consisting of the hasp plate B having a bead 16 struck up from sheet metal the combined lock and hasp pivoted Within the space inclosed by said bead, and the combined guard and keeper with the continuous struck up bead 17 with its ends meeting the ends of the bead in said hasp plate, substantially as described and for the purpose specified.

2. In a hasp lock, the hasp plate B having the bead 16 in the form of an inverted U and the integral dowel pins 13 projectingfrom the lower ends of said bead all struck up from a single piece of sheet metal, substantially as described and for the purpose specified.

3. In a hasp lock the hasp plate B having the bead 16 in the form of an inverted U, dowel pins projecting from the lower ends of said bead, pintle recesses in theinner side Walls of said head and the cross bar 12 connecting the lower ends of said bead, the combined lock hasp pivoted within the space inclosed by said U shaped bead, its pintle restin g in said side recesses of said bead and projecting into the hollow part thereof, and the securing plate 15 within said hollow bead, substantially as described and for the purpose specified.
