COMPANY, rim, or Jamestown, roan, A conronarron on NEW "sonic;


Application filed September 17, 1926. Serial No. 136,090.

mechanisms for looking a plurality of drawers' in'a drawer cabinet.

This invention resides in the provision of locking mechanism actuated by suitable means for locking drawers in a cabinet, and in the details of constructionthereof, as set forth in the following specification, and in the drawings which form a part thereof, and in which- Fig. 1 is a perspective view of a tiling cabinet equipped with locking mechanism embodying ono'form of this invention; and

Figs. 2, 3, 1 and 5 are perspective views of p I 'the other end on the p n- 66. The other arm various parts of said locking mechanism.

For the purpose of illustration 1S shown a vertical filing cabinet'GO provided with a plurality of drawers 27, only one of which is here shown, the top drawer being removed in order to permit a showing of part of the looking mechanism. At the side of each drawer 27 is mounted a stop 32, which coacts with blocks 40 pivotally mounted upon a reciprocable channel bar 33. The angular stops 32 are secured in any suitable manner, as by welding, to each side wall of the drawer 27. The blocks 40 are located within the channel bar 33, the ends thereof extending horizontally toward the drawer 27. lVhen the channel bar 33 has been reciprocated to move the blocks into the horizontalline of travel the stops 32 follow, said stops will strike the blocks thus preventing the withdrawal of the drawer. Further reciprocation of the bar 33 will remove said blocks from the line of travel of the stops 32 and permit said'drawer to be withdrawn. The construction of t 1e stops 32, bar 33 and blocks 40 is the same as that set forth in my copending application Serial. No. 136,089 filed September 17, 1926, and hence not herein set forth in detail.

1 The cabinet includes uprights 25 to which side panels 68 are suitably secured and a cap or cover 78. The drawers 27 maybe supported in any suitable manner, as for instance by means of guides 67.

The bar 33 is mounted behind one of the uprights 25 and is supported by angle straps 69 (see Fig. 5), which are fixed to the upright 25 and extend across and at the rear of the bar 33, thus forming with the panel 68 and upright 25 a way within which the bar reciprocates.

The bar 33 is actuated by an oscillatable pin 61 mounted in the cabinet preferably in the cap 78. Ashore shown the pin isat the middle of. the front of the cap, but itcould obviously be placed elsewhere desired. The pin 61 comprises a shaft 62 carried in a bracket 63, and controlled by a key knob mechanism 64 The particular construction of the'mechanisni 64 forms'no part ofthe. present invention and is not, therefore, set forth in detail. The shaft 62 terminates in a disc 65, from which'projects an ofi-eenter pin 66.

A. lever mounted to oscillate in a support 71 fixed'on the cabinet 60 is connected to the pin 61 by a link 72 pivoted at one end, on the upper arm 73 of the lever70 and at 74: of the lever 7 O engages the bar 33 by en tering a slot 75 in a block 76, rigidlysecured in the channel of the bar 33. r

Obviously, by oscillating the pin '61 the link 72 will actuate the lever 70 and raise or lower the bar 33. When .the bar israised as in ig. 1, the blocks 40 will be in front ofthe stops 32 and will lock the drawers 27 in place, and when the bar 33 is lowered the blocks 40 will free the stops 32 so that the drawers 27 can be opened. v

In order to avoid the possibility of lowering the blocks 40 and thus releasing the drawand the upright.

While one embodiment of this invention has been shownand described,applicant is not limited thereto, since it is obvious that other embodiments can be made without departing from the spirit and scope of this invention as set forth in the following claims.

Having thus setforth my invention what I claim as new and for which I desire protec tion by Letters Fatent is:

1. Locking mechanism for a tier of draw- 7 ers in a cabinet, including an upright and a side panel, comprising a channel bar mounted to reciprocate at. the joinder of said upright and said panel, an angle strap carried by said upright and extended across said bar and at one side thereof, a pin mounted in said cab inet for oscillation and means connecting said pin to said bar, whereby the oscillation of said pin causes the reciprocation of said bar.

2. .Locking mechanism for a tier of drawers in a cabinet, including an upright and a side panel, comprising achannel bar mounted to reciprocate at the joinder of said upright and said panel, an angle strap carried bysaid upright and extended across said bar and at one side thereof, blocks on sald bar and stops on the side of each drawer, said blocks and stops being so arranged that when said bar is 111 one position said blocks are in .lront of said stops and lock said drawers in 3. Locking mechanism for a tier of drawers in a cabinet having an upright and a side panel, a channel bar. mounted to reciprocate at the joinder of said upright and said panel, an angle strap extending across and at one side of said bar, whereby said upright, panel and strap form a Way in which said bar reciprocates, blocks on said bar and stops on said drawers, said blocks and stops being so located that when said bar is in one position, said blocks will be in front of said stops and lock said drawers in place, a pin mounted in said cabinet for oscillation including a shaft having at one end anol'l-center pin, a lever mounted to oscillate in said cabinet, one arm t which lever engages said bar, and a link pivoted at one end on said oil-center pin, and at the other end on the other arm of said lever, whereby the oscillationo'f said pin will reciprocate said bar and lockor unlock said drawers.
