rra sATEs vPA"1E1\Vr1`o1=rnEj FREDERICK B. WALTER, OF VJABASH, INDIANA, ASSIGNOR TO B. WALTER 8c COMPANY,

INC., F VJABASH, INDIANA, A OORPORATIN F INDIANA TABLE LATCH Application filed February 15, 1930. lSerial No. 428,847.

My invention relates to improvements in latches for table tops and is particularly din rected toward that type ot latch adapted for drawing together and connecting the sections of a top extension table.

The invention has for one of its objects ythe provision of a simple, cheaply manufactured latch, which permits the minimum separation oli' the table leaves.

For the purpose of disclosing my invention, I have illustrated one embodiment thereof in the accompanying drawing, in Which:

Fig. 1 is a partial sectional View of a table showing my lat-ch applied;

Fig. 2 is a bottom plan thereof;

Fig. 8 is a bottom plan of the latch with, the cover member in section;

F ig. 4 is a sectional view'taken on the line 4 4 of Fig. 8;

Fig. 5 is a bottom plan of the latch, the cover being broken away and showing the latch in a diiierent position to that shown in Fig. 3;

Fig. 6 is a bottom plan of the handle mounting; and

Fig. 7 is a detail section on the line 7 7 of Fig. 6.

In the embodiment illustrated, one eXtension section 1 oi: the table is provided with a keeper which may comprise a flat bar 2 having a down turned lip 3 at its end, the bar 2 being secured to the under face of the extension section.

The latch proper comprises a base 4 provided with suitable screw openings 5 for securing the same to the opposite table eX- tension member 6. This base is provided with a longitudinally movable pry comprising a bar 7 slidable on the base and guided through the medium of a longitudinally eX- tending slot 8 in the bar adapted to receive a guide 9 struck up from the base. One edge of the pry is provided with a semicircular recess 10 adapted to receive a correspondingly shaped lng 11 on the bottom end of the latch bar 12. This bar is provided with an engaging catch 13 at its outer end and opposite the lug 11 with an arm 14 adapted to contact, when the bar 7 and with it the latch 12 is moved in one direc,.- tion, with a stop 15 struck up from the bottom of the base 4.

A cover member 16is provided, the side Walls oi" which are provided with ears 17 adapted to take into openings 18 formed in the base for securing the cover member in position. One of the side Walls of this cover member carries a flat spring 19y anchored atone end r20 in the side wall and having its opposite end bearing against the latchportion l2 and biasing the latch toward engaging position. The latch is manipulated by a handle 21 pivoted on a supporting plate 22 and connected with the pry bar 7 by a rod 23. This handle is provided with a pin 24 operating in an arcuate slot V25 formed in the support 22, the slot being so positioned that when the handle is manipulated to move the latch to locking position,

the pin 24 will occupy a portion of the slot 25 in suchl aposition as to prevent the handle from swinging on its pivot under any tendency to separate the two table sections. Y

In operation with the latch in its locking position, as shown in Fig. 5, the operating handle is in the position shown in Fig. 6. In order to unlatch the parts, the handle is swung to the position shown in Fig. 2. This advances the pry 7 into engagement With theA keeper 3 and at the same time moves the latch member forward with the pry causing the arm 14 to engage the stop and swinging the latch out of engagement with the keeper so that the continued for- Y ward movement of the pry will force the two table sections apart.

I claim as my invention:

l. The combination with a keeper, of lato 1 mechanism comprising a base, a lug integra' with said base, a pry bar slidably mounted on said base and provided with an elongated slot guidingly receiving said lug, a latch pivotally secured to said pry bar and operatively associated with said keeper, a cover associated with said base, spring means carried by said cover and urging said latch toward retaining engagement with said keeper, and means independent of said lug and engageable by said latch, upon movement of said pry bar toward said keeper, to move said latch out of retaining engagement With said keeper.

2. Latch mechanism comprising a base, a pry bar slidably mounted on said base, cooperable means on said base and bar for guiding movement of said bar, a latch pivotally secured to said pry bar, a cover associated with said base, spring means associated With said cover and urging said latch to move in one direction about its pivotal axis, and means independent of said guide means and engageable by said latch, upon movement of said bar in one direction, to move said latch against the tendency of said spring means.

3. Latch mechanism comprising` a slidably mounted pry bar formed With a part-circu lar recess therein, said recess opening through one edge of said bar, and the opening being of less magnitude than a diameter of said recess, a latch provided With a cylindrical boss and said boss being received in said recess, and means cooperable With said latch, upon movement of said bar in one direction, to effect oscillation of said boss in said recess.

4. Latch mechanism comprising a slidably mounted pry bar formed With a part-circular recess therein, said recess opening through one edge of said bar, and the opening being of less magnitude than a diameter of said recess, a latch provided With a cylindrical boss and said boss being received in said recess, means for holding said boss against axial displacement from said recess, and means cooperable With said latch, upon movement of said bar in one direction, to effect oscillation of said boss in said recess.

5. Latch mechanism comprising a sheet metal base and a sheet metal cover associated with said base to form a housing, a pry bar slidably mounted Within said housing and formed with a part-circular recess therein, said recess opening through one edge of said bar, and the opening being of less magnitude than a diameter of said recess, a latch provided With a cylindrical boss and said boss being received in said recess, spring means urging said latch to oscillate in one direction about the axis of its boss, and means cooperable With said latch, upon movement of said bar in one direction, to move said latch against the tendency of said spring means.

In Witness whereof, FREDERICK B. WALTER have hereunto set my hand at Wabash, Indiana, this 8th day of February, A. D. one thousand nine hundred and thirty.

'FREDERICK B. WALTER.
