the provision of a construction which is new and novel and which facilitates constructing the cabinet entirely in wood.

In the accompanyingdrawings wherein i have illustrated one embodiment of my invention:

Fig. 1 is a view in perspective of the completed cabinet; a V Q V V Fig. 2 is a section taken substantially on the line 2-2 of Fig. 1; V

Fig. 3 is a section substantially on the line 3 --3 of Fig. .2; s

Fig. 4 is a View showing the drawer guides before assembly; l r

Fig. 5 is a part sectional viewshowing details of the drawer compressor; 1

Fig. 6 is a viewin section of the slide andguide mechanism at each side of the-drawer; and

Fig. 7 is a cross section :of part or the drawer compressor. a

Referring to the drawings in detail: 2 designates the sidewalls of the cabinet and A one of the drawers thereof; The drawer sides aredesignated 5, while the bottom of the drawer is designatedB. H

Secured on the" outside of the drawer to each ii each of these wooden strips being provided throughout part of its upper edge with a longifloating guides were overlap ed; "In seamen the upper uiding strips 2 1 are reduced n depth throughout carter their length, as shown at as,

to provide a shoulder 32 in the lower edge of each of these strips these shoulders cooperating with 'a pih'Sd'at the rear end or each of the floating guides 18'. This limits the outward movementgor the fioating guides with respect to the strips 2 3.

j The drawer cempressor is shown in Figs. and 5. From these figures of the drawings it will be seen that the compressor comprises a rectangular piece or wood 38 extending from sidewall to side- Wall Of the drawer. secured t0 the back (if the member 36 at each end thereof are wooden blocks 38. These blocks at their outer races abut the sidewalls tor the drawer. On the outer face of each block, thatis, the face adjacent the drawer These tongues extend lengthwise of, the blocks and lengthwise of the drawer, and are adapted to ride in grooves 42 provided for that purpose in the inner face of eachdrawer sidewall 5 The tongues ii! are provided for the purpose of properly guiding the compressor 36 in its movement lengthwise and forth in adjusting the same. The upper edge sidewall 5 thereofis an elongated wooden strip The strips Ii] just referred to are received by ing drawer carrying wooden guides l8 which are provided at each side of the drawer, these fioating guides resting upon wooden strips 28 secured to the inside of the cabinet wall. The wooden guides l8 which, as above noted, rest upon the wooden strips 23, carry the weight of the drawer, and hence I impregnate these guides with a lubricant such as paraffin. A pin 22 is provided at the outer end of each of the grooves l6 of the floating guides l8, these pins extending into the grooves 42 in the strips iii, thereby to limit the outward travel of the strips Hi with respect to the floating guides.

Secured to the interior of the sidewalls of the cabinet 2 immediately above the floating guides [8 are wooden upper guiding strips. The upper edge of each of the floating guides is cutback throughout its length, as shown at 26, and each of the strips 24 is cut back throughout part of its lower edge, as shown at'at, so that strips 24 and of each of these grooves is straight and smooth and parallel to the long axis of the drawer. The

bottom of each of these grooves, however, is

notched, as shown at 44. These are looking notches or ratchets whichcooperate with a dowel locking rod it extending across the drawer behind the compressor board 36, the ends of this rod passing through vertically extending slots 53 in the bloclrs 38 and'tongues t8 and into the groove 42. The slots 53 are elongated vertically of the blocks 38 and tongues 49 so as to permit the looking rod as to be raised out of the locking notches 44 when it is desired to shift the compressor lengthwise of the drawer in either direction. This rod falls into place by gravity and while it has a positive locking action, nevertheless no springs are required for its operation; This is a real advantage in a device of this character.

a It. will be seen from the foregoing that I have provided a filing cabinet which is of such construction as to permit the same to be made entirely of wood, without, however, sacrificing the strength necessary in an article of this nature.

.be seen, furthermore, that so far as the floating guide and the cooperating members shown in i only move for about half its length with respect to member 24. In other words, there is always a substantial overlap of these three members sufficient to prevent tipping of the drawer even when the same is'fully' loaded. lhis substantial overlap also provides a long bearing surface so that the drawer may be opened and closed with the minimum effort.

It is to be understood that changes maybe made'in the details of construction and arrangement of parts herein described without departing from the spirit and scope of my invention.

What I claim is:

, 1. In a cabinet drawer, a compressor board withinthe drawer, Wooden blocks secured to the rear face of the compressor board adjacenteach edge thereof,,a tongue on the outer faceof each of said blocks riding in grooves formed in the innerfaces of'the drawer sidewalls, whereby the compressor board will be held in upright position v and may be moved along the drawer to vary the drawers capacity, a locking bar extending transversely of'the drawer, said bar passing through slots in said blocks and projecting into said grooves, the lower surface of each of said grooves being shouldered, and said bar being engageable with said shoulders, thereby-to lock the cornpressor board in adjusted position.

2. In a cabinet drawer, a compressor board,

within the drawer, wooden blocks secured to one face of the compressor board adjacent the drawer sidewalls, a groove extending lengthwise of the drawer in the, inner face of each drawer sidewall,

tongues carried by said blocks and extending intosaid grooves whereby the compressorboard will be guided as it is moved lengthwise of the which the rod is adapted to move by gravity thereby to lock the compressor board in adjusted position.

3. In a cabinet drawer, a compressor board within the drawer, wooden blocks secured to the rear face of said board adjacent each edge ther of, a tongue on the outer face of each block and riding in a corresponding groove formed in the inner face of the adjacent drawer sidewall, a lockingbar extending transversely of the drawer through vertically extending slots in said blocks and projecting into said grooves, locking shoulders in the lower surface of said grooves, said 'bar moving by gravity into engagement with opposed shoulders to lock the board against movement rearwardly of the drawer, the slots in said blocks being sufficiently long to permit the rod to be manually lifted out of engagement with said locking shoulders to permit shifting of the compressor board.

4. In a cabinet drawer, -a compressor board withu'n the drawer, wooden blocks secured to the rear face of the compressor board adjacent each edge thereof; a tongue on the outer face of each or said blocks riding in grooves formed in the inner faces of the drawer sidewalls to hold the board upright whilepermittin'g it to move length- Wise of the drawer to vary the capacity of the drawer, and means for locking the compressor board in adjusted'position, said locking means comprising a dowel rod attached to and extending crosswise of-the compressor board through slots in said blocks and tongues and into said grooves, and shoulders on one face of the grooves in said drawer sidewalls selectively engageable by the projecting ends of the dowel rod to lock the compressor board adjusted position.
