To ALL 'PERSONS To WHOM ,THESE PRESENTS MAY COME:
Be it known that I, JOHN F. FORD, of Boston, in the county of Suffolk, and State yet' Massachusetts, have invented an Improved Safety-Guard for' Windows; and do hereby declare the same .to be fully described in the following specification, and represented in the accompanying drawings, of Which- Figure lis a side elevation, Figure 2 a top view, and l Figure 3 a vertical and longitudinal section of it. o In such drawings, A and B are-two bars, arranged parallel to each other, and provided outher outer sides with teeth or spurs, as shown at a a. A f
'Each of such bars has three projections b c b, extending fromits inner surface, each of such projections l being socketed axially; each ofthe middle-projections ofthe two .bars containing in its socket a helical spring, d, and is to receive `one end of aroundbar, (,V which maybe clamped to one of the projections c by'clam'pscrew, e, screwed laterally ito it. I
Other round bars D, arranged parallel to the har C, and with respect to it, in manner as represented, have male screws fg on their opposite ends, the pitch of onebeing'th'e reverse of that ofthe .other of each-oi` suchy bars. These screws are to screw into the socketed projections b b of the tv vo bars AIB.'
By revolving tho Lipper and lower bars D D, the two bars A B may be made to either approach or recede from each other, the same being tov enable the guard to be fitted or-adjusted'-to a window-frame, and be fastened in place therein, by forcing the spurs of the guard into the opposite sides of theframe.
The purpose of the guard is to prevent young children fromfalling outof the window. .l
I claim, as my invention, the window-guard, as composed of the bars A B G D, arranged and'connectedby screws, and having spurs, substantially as described. I also claim the combi-nation and arrangement of the springs d d in the sockets of the middle projections of the bars A B, with such bars and their spurs, and the barsC applied to the bars A B, substantially as specified.I l A j JOHN F. FORD. Witnesses:
