FIRE-SCREEN GATE.

SPECIFICATION forming part' of Lettersatent N o. 698,848, dated April 29, 19.02.

' Application nea :rune 28, 1901. seria No. 66,444. (No moans;

vented a new and useful Fire-Screen Gate`,'of

which the following isa specification.

My invention relates to an improvement in re-screens in which said fire-screens are pro-y vided with hinges and a lock and the reframe with hinging and locking members, as is hereinafter described; and the objects of my improvement are, first, to hang a firescreen gate on a fire-frame without marring the front of the frame or mantel; second, to have the fire-screen gate always locked when in closed position, and, third, to provide a new, safe, and convenient handling of a tirescreen in the form of a gate. These objects are attained by attaching a fire-screen gate to an open replace, as illustrated in the accompanying drawings, in which- Figure 1 shows the elevation of an open lireframe having hinge members and a lockcatch. Fig. 2 is a detail perspective showing hinges with elbowed arms, indentation of the rim of the screen, bolts and nuts, and-manner of alxing hinges to screen. elevation view of a fire-screen mounted on arm and elbow hinges and carrying a lock. Fig. 4 is a detail perspective showing the points of the frame on which hinge members are affixed. Fig. 5 is a multiple View of an elevation, partly in section, showing the several parts of the lock. Fig. 6 is an elevation View of the lock in closed position. Fig. 7 is a front elevation of a replace, showing iirescreen gate closed and locked; and Fig. 8 is a detail perspective showing the lock-plate aflixed wit-hin the indentation of the screen.

The fire-frame D, Fig. l, is provided with hinge members h h and a lock-catch fu. The hinge members are perpendicularly bored for threaded bolts m m, Fig. 2, and flat side up protrude from the left wall y of fireplace..

These members h h are united to the back side of frame D at o o, Fig. 4, which sends them back into the fireplace as far at least as the thickness of the frame at its fire edge w, Fig. 4. The lock-catch fu, Fig. 1, protrudes flat side front from the right wall 'y of fireplace. In the manner of hinge' members h 7L Fig. 3 is anv lock-catch@ is united to the back side of frame D at p, Fig. l, and also sent back into the replace as far as the thickness of frame shown at Fig. V4. Catch fv is not bored.

The hinges A B, Fig. 2, are constructed with two leaves each, an upper leaf a a and a lower leaf b b, which are held and made inseparable by pivot-pins c c, upon which the lower leaf Z7 of hinge A and the upper leaf d of hinge B turn. These two leaves b and dare united to the screen C at d d, Fig. 2, and owing to their shape carry the screen awayfrom frame D when ,the screenis swung open. The upper leaf a of hinge Al and the lower leaf b of hinge B are made with arms c e, which are crooked by elbows g g. At the end of arms e e bored flanges ZZprotrude from the lower edges of e e and will rest u'pon the upper side of hinge members h h when bolted thereto.. From elbows g g to anges l Z arms e e may be any necessary length, and in width will conform to the thickness of their hingeleaves. Hinges A B. being united to screen C at CZ d, the arms e epass under au indentation of the rim of the screen at ff, Fig. 2, and are carried by elbows g g around the fire edge of the frame D, Fig. 4. Flangesllof arms e e are then connected with the upper sides of bored hinge members h 7i, at o o, Fig. 4, and are made fast with threaded bolts m m and nuts s s, Fig. 2. The hinges are thus brought into action in frontof the lire-frame, although hung from hinge members hh on left wall y within the fire-place. This manner of hanging the screen-gate insures against defacement of the frame or mantel and leaves no hinge or locking members in sight when the screen is taken down and the fire-front put up for the summer.

lIn the construction of the lock in Fig. 5 knob E is made with a square hollow extension or handle b', which extends into the knob, as shown at c'. the hollow handle o has a small threaded boring'b, as shown in Fig. 5, to receive a screen, the boring running horizontally with the handle. The size of the boring depends on the thickness of the metal. At the end c of hollow handle b a cavity d as deep as the thickness of the metal extends across the floor or lower side of handle b', as shown in Each side of the open end of f vIO the exposed view of the inner parts of knob E. A pin g', aixed to a push-button j", extends up through an apertureh' in knob E and passes into a perforation It of the lower side of handle h at c. The second part of the lock consists of two steel prongs Z Z', having anges m' m', made in one piece and bent in the form shown in drawings. The prongs must be thinenough to provide an easy spring when pressure is brought to bear upon them.

Precisely in the center of the curve at n.' av

steel rod p is firmly affixed. This rod eX- tends toward the flanges m m', and at r will be the thickness of lock-catch fu short of the length of prongs Z Z' whenlanges m' fm are brought together. A rod t', having a tumbler s', is pivoted at u', so that the tumbler will easily fall into cavity d of handle b. Rod t has an overhanging edge s at tumbler s' to catch the pin g when button f is pushed. A guard fu', made in thefform of the letter H and perforatedl at fu2 'v2 r3, has a cross-piece w', supporting upper side guards as cc and lower side guards 56:12. Guard c covers the open end of handle b and is made to permit the prongs Z' Z to work in. The upper and lower side guards az and cross-piece w will thus keep the prongs Z Z in place when inserted intoth'e handle b' and prevent the handle from slippingout of the plate y when the lock is open.

The screen C is indented at 2:' z', at which points a lock-plate y is aflixed firmly to the screen and its rim. The plate y' is provided with an aperture e". On the front side of the plate the aperture is rimmed'to steady handle b and is made to permit the handle to slide in without too much freedom.

Having thus described the construction of the several parts of the lock,a furtherexposition will show how they are brought together. The plate y', Fig. 5, is firmly united to the screen and its rim at the points z', the indentation of the screen permitting the plate to present a lat front'. The handle b' is inserted into the aperture s, and the prongs Z' Z are then inserted into the hollow of handle b and held in place by guard 1;,which is passed over rod p', through perforation v3, and screwed to the handle at threaded borings b" and perforations 112. This unites the lock in an open position to the screen. To close the lock, the screen is swung against the ireframe D at 1o, Fig. 1, which brings the end fr' of rod p', Fig. 5, against the flat or front side of lock-catch fv of frame D. Thus is formed a point of resistance against which the'han'-4 dle lb is pressed, the result being that as rod p can go no farther the handle b' is pushed upon the prongs Z' Z until the tumbler sfalls into cavity d' in handle Z7', which happens when the handle is pushed far enoughA upon the prongs to bring the a'n'ges m fm. together `on the otherside of catch o. `This act locks the screen, as in Fig. 7, and holds the lock F securely closed, as in Fig. 6, by the tumbler s being in cavity d', the ypointr of rod p' being against the near -side of'lock-catch u and the'llanges'm` m having been brought together on the far side of catch fu. To release the lock, the buttonf in knob E is pressed upward, which sends the pin g through the perforation k in handle b and against the overhangin g edge s" of rod t', thereby raising the tumbler s out of cavity d' and allowing handle b to be pulled 0E the prongs t Z', thus opening the lock and releasing the screengate from its locked position.

I am aware that fire-screens are in general use and have been mounted in dierent forms; but I am not aware that the combination as herein set forth vhas ever been used.

What I claim-as my invention, and ldesire to secure by Letters Patent, is-

l. The combination, in a lire-screen gate, of a lire-frame having hinge members 71, h, and lock-catch fv, affixed tothe back side of the frame at the fire edge, a fire-screen mounted on arm and elbow hinges A B, to be united to the hinge members on the frame, the arms e e and elbows g g affixed to said hinges an indented rim for the passage of hinge-arms, and the lock F` aixed to the screen to coperate with the lock-catch onpthe frame, all substantially as set forth. l

2. A ure-screen gate comprising a catch and a hinged screen having an indentation, a lock-plate therein, a lock having a knob carrying a pin and push-button, a hollow handle aftixed to the knob, spring members and a stop member, movable within said handle and having a rod and tumbler to be operated by said push-button, said spring members coperating with the catch above mentioned; all substantially as shown.

In testimony whereof I have signed lmy name to this specification in the presence ot' two subscribing witnesses.
