11 Claims.

This invention relates to filing cabinets and. it has for one of its objects the provision of a filing cabinet construction in which the lower filin drawer can be elevated to a convenient height for use without disconnecting it from the cabinet casing.

Another object of the invention is to provide a filing unit including extensible supports adapted to carry a drawer withdrawn entirely from the cabinet, and manually operable elevating mechanism for positioning the drawer at a convenient height for utilization.

Filing cabinets of the type in which a tier of drawers are installed in a casing have previously been so arranged that the lowermost drawer is disposed immediately adjacent the floor upon which the cabinet rests, and in this position requires filing clerks and others who have access to the files to stoop excessively while filing papers or withdrawing them from the files. Examination of the files in this position is also likely to be injurious to the eyes. Since many files of this type are relatively heavy it is inconvenient to withdraw them entirely from the casing and lift them to a table or other elevation where they can be conveniently utilized. In such construction a considerable space is customarily left unused at the bottom of the casing because of the inconvenience and disadvantages referred to above.

According to this invention a cabinet is provided in which the lowermost drawer is mounted upon a carriage or frame which is extensible and can be withdrawn to expose the entire length of the drawer. Then by manipulating a handle a mechanism elevates the drawer to a convenient height at which it remains until the handle is operated in the other direction to restore the drawer to its lower normal position. Then the drawer can be easily forced back into the cabinet casing. This mechanism requires relatively small space and is not complicated in its structure or operation. It is especially suitable for installation in the type of cabinets in which the drawers are relatively heavy and where it is desirable to utilize the filing space immediately adjacent the floor.

In. practicing the invention a filing cabinet 10 is provided 7 including several superposed drawers 11 and 12 mounted in a cabinet casing 15. Vertical reinforcing members 16, transverse drawer division members 17, side and. rear walls 19, and 20, comprise the cabinet casing and are constructed and assembled in a conventional manner. Drawer stops 22 of U-shape are rigidly secured adjacent the front of the casing upon the lower transverse member 17.

A telescoping or extensible carriage frame 23 is mounted in the lower portion of the casing 15 and includes horizontal channel members 25 rigidly secured along the lower portions of the casing side walls 20. Each channel member 25 comprises a web 26, outwardly extending flanges 27, and a rear inwardly turned flange stop 28 that facilitates welding or otherwise securing the panel member to the rear wall of the casing. The front end of the channel has a flat or plane portion 29 which is secured against the inner side of the front comer reinforcing casing member 16. A plurality of rollers 31, 32, and 33 located at the front end, intermediate portion, and adjacent the rear end, respectively, of each channel member are disposed upon the side of the web 26 opposite the flanges 27 and are journalled uponstud pins 35, 36 and 3'7.

A second pair ofchannel members having their flanges 39 extending outwardly in opposite directions are telescoped inside or between the channels 25, and the flanges 39 constitute tracks in which the rollers 31, 32 and 33 are disposed. Transverse members 50, 51 and 52 rigidly secured at the front end, intermediate portions, and rear ends, respectively, of the channel members 38 provide a horizontally slidable rigid frame or carriage section wherein the channel members or 119 tracks are supported by the rollers 31, 32 and 33. It will be observed that the transverse members are secured upon the lower sides of the channel members and that the intermediate transverse member 51 is located nearer the rear ends of the channel members 38 than the front ends thereof. A plurality of rollers 55, 56 and 57 journalled upon stud pins 58, 59 and 60, respectively, are mounted at the front, intermediate, and rear portions of the channel members 38.

Athirdpairofchannelmembers62 having their channel flanges 63 extending outwardly are movable between the channel members 38, and their flanges provide tracks which ride upon the rollers 55, 56 and 57. A plate 65 having upwardly turned side flanges 66 is rigidly secured by welding or other means to the channel members 62 to provide a unitary drawer carrying structure or drawer carrier member. Front and rear inwardlyturnedflanges67and68areprovidedupon the channel members 62,- and a front facing strip 69 is rigi ly secured to the flanges 67 across the front ends of the channel members 62;

Opposed dogs 70 are pivotally mounted, as indicated at 72, upon the sides of the channel members 63 opposite the flanges 63 at locations substantially midway between the channel member ends, and opposite ends 73 and 75 of each dog (Fig. 77) extend upwardly and downwardly beyond the edges of the respective channel members. The lower end 75 of the dog is relatively heavy and consequently it always tends to assume a vertical position, as illustrated in Fig. 7.

AsbestshowninFig.1theframe23 isinits normal unextended position inside the casing and the facing strip 69 is flush with the front of the casing. The rear flanges 28 of the channel members serve asstops for arresting rearward movement of the flanges 68 of the channel members 62. Rearward movement of the channel members 38 is limited by the transverse member 50 abutting the stops 22, and forward movement of these members is limited by the transverse member 51 abutting the opposite side of the stops 22.

members 62 which are carried by the channel members 38 is limited by one end 75 of each dog 70 abutting the transverse member while the other end 73 of each dog is impinging upon the walls of registering slots 76 extending through the bottom of the plate and through a reinforcing ship 77 fastened uponthe upper surface of the plate. In the normal rearward movement of the channel members 62, the dogs remain in an upright position and do not strike any of the elementsofthecasingorframe. Thestops22are so positioned as to be out of the path of movement of the dogs.

However, by moving the channel member 62 slightly to the right, as viewed in Fig. 5, the dogs may be manually pivoted or tilted and the channel members 62 withdrawn from the channel members 38. In assembling these members the dog automatically pivots and rides over the transverse member 50 8 its upper end swings into the slots 76..

The lazy-tong drawer elevating device 80 mounted upon the plates 65 includes pairs of links 82 and 83 having their front or outer ends pivotally connected upon pins 85 and 86 secured in angle brackets 87 and 88. One bracket 87 is rigidly secured to the upper surface of the plate 65 while the other bracket 88 is rigidly secured to the lower surface of a drawer receiving channel or support. member 89 that supports the Forward and outward movement of the channeldrawer .12. Side and rear upwardly disposed flanges 90 serve to position the drawer firmly and a front downwardly disposed flange 92 remforces the front portion of the channel.

The rear or inner ends of the links are provided with pins 95 and 96 rigidly connected thereto for horizontal sliding movement in horizontally disposed slots 97 and 98, (Figs. 2 and 6), formed in plates 99 and 100 that are rigidly secured to .the plate 65 and to the side flanges 90 of the channel 89, respectively. A set of links 82, 83 is disposed on each side of the drawer 12. Opposite ends of a horizontal transverse rod 102 are pivotally supported by intermediate portions of the links 82 and 83 and an angular elevating lever 103 has its intermediate angular portion rigidly secured, as indicated at 105, to one end of the rod. It will be observed that the plate 65 is wider than the channel 89 and drawer 12, and that the flanges 66 of the former extend beyond the edges of the channel.

The lever 103 comprises an off-set handle 106 which is normally disposed in an inclined position, and a relatively shorter arm 107 having a roller 108 .iournalled in its outer end. In its 100 normal position the arm 107 lies substantially horizontally along the upper surface of the reinforcing strip 77 and the roller 108 rests upon the surface of this strip. At the end of the rod 102 opposite the lever 103, one end of an arm 109 is rigidly secured in the same manner as the lever and corresponds substantially to the arm 107.-

A roller 110 secured upon the end of the arm 109 and similar to the roller 108 rests upon the upper surface of the reinforcing strip 107 adjacent 110 the edge of the plate opposite the arm 108. Each of a pair of fastening members '112 secured to the bottom of the drawer 12 is provided with a central web 113 and oppositely turned flanges 115 for disposition in slots 116 in the bottom of the 115 channel member 89. These slots are relatively wide for the purpose of receiving the flanges 115 which are disposed therethrough. Then, by relatively sliding the channel and drawer the webs 113 are slipped into narrower slots 117 communi- 120 cating with the relatively wide slots, and from which the fastening members cannot be released without again relatively sliding the drawer and channel.

In manipulating the drawer 12, it is drawn outwardly from the cabinet casing and the channel members 38 ride outwardly upon the rollers 31,

32 and 33 until the transverse member 51 strikes the stop 22 in the position of the channel members 38 as illustrated in Fig. 2. Then the channel members 62 ride upon the rollers 55, 56 and 57 until the dog end 75 strikes the transverse member 50. The drawer is thus positioned completely outside the casing in the position shown in the full lines of Fig. 2.

In order to elevate the drawer the operator draws the handle 106 upwardly-in the direction of the arrow shown at the end of the handle in Fig. 2. During this operation the rollers 108 and 110 of the arms 107 and 109, respectively, roll upon the upper surface of the plate 77 and the pins 95 and 96 of the links slide inwardly in the slots 97 and 98 until the lazy-tong device and drawer are in the elevated or extended position shown in broken lines of Fig. 2. It will be observed that the lever 103 is pivotally actuated upon the rod 102 until the roller 108 passes the dead center with respect to the rod. Thus the lever may be released and the drawer will remain in its elevated position. The operation just described is reversed when it is desired to return the drawerto its lower position and to slide or roll it into the casing.

The lever 103 is held in the dotted line position as shown in Fig. 2 after passing dead center, so as to retain the drawer in elevated position by the rollers 108 and 110 engaging stops 120 mounted at opposite sides on plate 65 adjacent side flanges 66. One of these stops is shown clearly in Figs. 2 and 5 and the other is mounted in the corresponding position at the opposite side of plate 65.
