To all whom t may concern: v

Be it knownthat I, JOHN J. I-IAssnLBAoH, a citizen of the United States, residing at Detroit, in 'the county of l/Vayne and State of Michigan, have invented certain new and useful Improvements in Racks, of which the following is a specification.

This invention relates to improvements in racks and particularly to rack for filing blue-prints, maps, drawings and similar flat sheets.

The objects of this invention are: y

First, to provide an improved rack for filing blue-prints or drawings which will permit the filing of a large number of drawings` in a small space and which can be swung back'against the wall when not in use.

Second, to provide a rack for filing drawings which oan be constructed at a low cost and which will economize the space needed for filing prints and drawings.

Third, to provide an improved rack for filingdrawings having a plurality of independently removable carriers so constructed that all related'drawings or prints can be carried by a single carrierV and removed from the rack in a group for examination without removing the other carriers or drawings. Y

Fourth, to provide an improved rack for :tiling drawings having a plurality of removable carriers, each carrier being so connumber of prints with one of the upper corners free to permit examination of there without removing the prints from the carrier.

Fifth, to provide removable carriers having novel clamping means, by which the sheets can be bound or secured in the carriers, said clamping means being quickly releasable.

Further objects, and objects relating to economies of operation and details of construction, will detinitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. My invention is clearly defined and pointed out inthe appended claims.

A structure constituting a preferred emthe data usually placedbodiment of my invention is illustrated in the accompanying drawings, forming a part of this specification, in which Figure I is a view in side elevation of a raclcconstructed in accordance with my invention.

Considering' the numbered parts of the drawing, my invention comprises a rack which is adapted to be supported on the wall and to carry a plurality of independently removable carriers in which the prints, drawings or sheets to be filed are clamped. The brackets 20 are fastened to the wall 2l by the screws 22. The bar 25, which is here shown as of square, tubular construction, has a head 23 disposed between the brackets 20 Patented Mar. 26, 1913.;

and carrying the pins 211 which are journaled in the brackets 2G. These pins ing thus journaled permit the bar 25 to swing in a horizontf-il plane. lfhe hollow bar 26 which is of slightly greater cross section than the bar is slidably upon said bar rlhis bar 26 carries the end plates A28 which are preferably of sheet metal stamped to the proper form. These end plates are tapered so that therlower end thereof is narrower thanthe top and are provided with a plurality of downwardly nclined slots at the sides thereof, the inner end of each slot being offset inwardly with reference to the slot :.bove. '.lhe ears 30 are provided on the upper corners of the end plate and are that they may be used to hold a card carry ing data referring to the drawings filed in. the rack. The ear 31 is stamped out from the body of the end plate to serve as a finger grip in moving the rack on the bar 25.

"hisraclr is designed to carry a plurality of independently rfeinovable carriers in which the sheets to be tiled can be clamped or bound. The rack shown in the drawings will carry six of t frese carriers and its capacity can be increased by providing end plates having additional slots. 1Sach carrier comprises a bar 32, approximately as long as the rack., having the portions 33 turned downwardly at the corners thereof to serve as legs for supporting the carrier when taken out of the rack and laid on a table in order to examine the drawings therein. i portion 34 at each end of the bar 32 is twisted so as to lie in a plane at an angle to the plane of the bar 32 and serve as pins for supporting the carrier in the rack. rlhe angle at which these pins Si are twisted is such that, when they are inserted in the slots 29, the carrier will lie in a vertical plane. rllhe portions Bil being flat they prevent turning or twisting of the carrier when in place in the rack. rt one end of the bar 32 there is provided the block 35 having an undercut, inclined face i556. A clamping plate 37, which is slightly narrower than the bar 32, has one end thereof inserted beneath the inclined face 36 of the bleek 3o and when said clamping plate is forcee agai @t the bar 32 by suitable clamping or locking means the sheets are securely bound in -theI carrier. rlfhe plate 37 is shorter than bar 3&3 for a purpose which will be forth here inafter.

In Figs. V11 to X1 inclusive, 1 have shown one form of clamping means. 1n this form, straps 38 are secured to the bottom face of the bar 32 and carry bearing blocks 89 in which one arm Ll-O of a roch arm has a bearing. Each of these bearing blocks has a' curved slot and the pinl carried by the arm 440 is disposed in said slot. rlhe rock arm has a portion 43 extending at right @il bef mounted bent parallel `to the plate so angles to the arm 40 and an arm le extend l ing right angles to the portion 43 and the arm 110. The arm 4:0 when in position in the bearing block 39 lies parallel to the bar while the arm dat extends over the clamping plate 37. A pin 4:5 is carried by the end of each arm f1.4 and a lever 16 is fulerumed on each of said pins 45, each of said levers being provided, at one end, with the nose L17 adapted to engage the upper surface ofthe clamping plate 37. The inner ends of the levers 11G are connected by the link d8, the ends of which are pivotally 'connected to the inner ends of the levers 4G by the pins 119. 'fr screw 50, having the head 51, threaded through the link 118 and the end of said screw engages the uppersurface of thc clamping plate 37.

1n Figs, X11 to XV inclusive, 1 have shown another form of clamping means which, in some cases, is to be preferred to the form above described in that it requires less space. rl`he blocks 52 are secured to the lower surface of the bar 39j and. the shaft 53 is journaled in said blocks. The worms are fixed on the shaft 53 and said shaft is provided with the head 55 by means of which it may be rotated. Blocks 56 are secured to the upper surface of the bar 32 and a stub shaft- 57 is journaled in each of said blocks 56 and extends through the bar carrying on its lower end, beneath the bar 32, a gear 58 meshing with the worin lllliper arms 59 are fixed to the upper ends of the shafts 57 and wedges 60 are provided on the upper surface of the clamping plate so that the wiping arms 59 will engage said wedges the shaft 57 is rotated so as to force the clamping plate 37 toward the bar B2. 1 have indicated the sheets bound in the carrier by the reference character A.

From the description of the parts given above, the operation of my device should be very readily understood. As pointed out above, the bar 25 is so mounted in the brackets 2O that it may be swung in a hori- '.fcontal plane so that the rack may be swung against the wall to econolnize space and moved to a position at right angles to the vall when it is desired to remove drawings from the rack. The rack proper consists of the hollow bar 26 carrying the end plates 28 and the rack can be moved away from the wail by sliding the hollow bar 2G on the har Q5. The end plates of the rack have the clined slots 29 which receive the pins 3 at the ends of the carrier. s already pointed out, the pins are fiat and lie in a plane at an angle to the plane of the earrier so that the carrier will lic in a vertical plane when mounted in the rack. The clamping plate 37 is shorter than the bar 32 of the Carrier so that the upper right hand corners of the drawings or sheets bound in the carrier are free and one may examine data on the sheets at this pointA without removing the sheets from the carrier. These carriers are independently removable from the rack and drawings or prints may be grouped or classified by filing all the prints of one group or class in a single carrier. If the drawings in this group are to be eX- amined, the carrier can be removed from the rack without disturbing the other carriers. The slots 29 are so arranged that the sheets in the carrier carried by the upper slots will lie in front of the sheets carried by the other carriers ,so .that any carrier can be removed without removing the others. when removed can be laid flat being supported by the legs 33.

The sheets are bound in the carrier between the clamping plate 37 and the bar 32 and means are provided for firmly forcing the clamping plate against the sheets to bind them against the bar. This clamping means is of such a nature that it will exert a considerable pressure on the clamping plate and will lock it positively but will, at the same time, be quickly releasable. In Figs. VII to XI inclusive, I have shown one form of clamping and locking means, while, in Figs. XII to XV inclusive, I have shown another form of clamping and locking means which I prefer to employ in some cases.

In the form shown in Figs. VII to XI, as the operator turns the screw the end thereofwill bear against the clamping plate 37 and will force the link 48 away from plate 37. Said link 48 is connected to the ends of levers 46, which are fulcrumed on the pins 45, so that the nose 47 of each lever bears down on the clamping plate 37. As a result, when the screw 50 is turned, pressure is applied to the clamping plate at three separate points. The levers 4G are carried so that they may be swung back away from the clamping plate 37 since the pins 45 are carried by the ends of the arms 44 of the rock arm. The movement of each of the rock arms is limited by the pin 41 disposed in the curved slot 42 so that an initial longitudinal movement of the rock4 arm is reonV a table quired. This longitudinal movement is impossible when the screw 50 is turned down to apply pressure to the clamping plate but, when the pressure is released, the rock armscan be rotated, with the pins 4l working in slots 42 and guiding the movement of the rock arms, so as to swing back the clamping means from above the clamping plate.

In the form shown in Figs. XII to XV inelusive, the clamping plate 37 is forced toward the bar 32, to bind the sheet in the carrier, by the engagement of the wiper arms 59 with the wedges ixed'on the upper surface of the clamping plate. The shaft 53 carries the worms 54 and, as it is rotated,

' the stub shafts 57 are rotated through the The carrier tube slidably mounted on said bar;

vsecured to the ends of said tube,

gears. 58 lmeshing with the worms. The rotation of each stub shaft causes the wiper arm 59 to move over the inclined surface of the wedge 60 forcing the clamping plate against the sheets. By turning the shaft 53 in the reverse direction, the wiper arms will be moved from over the clamping plate so that the latter can be freely removed.

I am aware that the embodiment of my invention, here shown and described, can be varied considerably without departing from the spirit of my invention and, hence, I desire to claim my invention broadly as indicated by the appended claims. I have found this particular embodiment, however, to be desirable from many standpoints and, therefore, I wish to claim it specifically as well as broadly. i
