This invention relates to supports for portable typewriters. l

There is provided a novel adjustable support which may be applied to the usual desk 5 or platform in a place of business, a counterpart thereof being attached to a home desk or table; and, when the machine is transported from oiice to home, it maybe easily and quickly placed upon the home support and readily adjusted thereto'and automatically locked in such position. The invention may include parallel rest rails, one directly engaging the grooves of buttons provided at one side of the typewriter-baseboard, and the other rail acting as a support for a slide or lock-plate, which is heldthereon byheaded studs engaging slots formed therein, said plate being arranged in y a plane coinciding with the plane of the zo ledge of the opposite rail and engaging the grooves of the buttons on its sider of the baseboard. A pull spring may be attached to this slide-plate and to a-liXed pin to normally draw said plate backwardly to cause the studscoacting' with the cam-slots to forcibly engage the buttons and lock the typewriter in an adjusted position against rearward movement but yieldingly permitting a forward movement thereof. This locking 3o relation may be relieved by pulling forward on a finger-piece .on the slide-plate against theaction of the spring whereby the type'- writer may be moved in either direction on the rails.

The improved support has a baseboard to which a set of the grooved buttons are applied, and means engage said buttons for guiding the machine as' it is placed in a desired position, where it is locked.

f 40 Some operatives are morey comfortable and accurate when the machine is very near, while other operatives are more comfortable and efficient when the machine is farther away. The invention affordssuch adjustments.

Other features and advantageswill hereinafter appear.

In the accompanying drawings, Figure 1 is a longitudinal section of a portable typewriter in position on my improved support, the section being taken about on the line 1 1 of Figure 2, with parts omitted.

Figure 2 isaa plan view of the improved typewriter-supportand shows the baseboard of tlietypewriter thereon to more clearly disclose or indicate the position of the grooved buttons carried thereon, parts being broken away. f

Figure 3 is a front view of the parts shown in Figure 2 and on a slightly enlarged scale. B0 Figuro'4 is a'sectional fragment, taken on line 4 4 of Figure 2, showingthe attachment of a button to the typewriter baseboard- Referring now to the drawings in detail, there is shown at l() a desk-board, tabletop or other horizontal' support, to which parallel metal rest rails 11 and 12 may be secured by screws 13, or other fastening devices. vvThe rails'are each of general Z bar formatioi'i, providing a foot-portion 14, and a longitudinal track`r rail or ledge-portion y15, joined by a short vertical web-portion- 16.

` The web-portion 1o 'of the rail 12, at the right hand of the operator, is arranged in a lower plane'than the ledgeV of the opposite rail and isprovided with headed studs 17j, which operate in connection with diagonal cam-slots 18 formed in a slidable lock plate ledge, track, rail, or bar 19, to normally guide Y said lock-plate inwardly,- t-hrough the pull- '80 ingiaction of a spiral spring 20, connected at one,y end to a lug 21 formed with said plate and to a fixed pin 22a, on t-he vertical webportion 16, of the rail 12.

So that a portable typewriter A maybe used in-connection with the above-described adjustable lock-support, the usual rubber feet o-r rests should be removed from the baseboard B and grooved' buttons 22 substituted therefor. These buttons may be secured directly to the baseboard of the typewriter by oppositely-'arranged screws 23, after which a rubber disk 24, or the regular rubber feet, may be secured by a longer and centrally-positioned screw 25, as in Figure 4 of the drawings. The lock-plate is further provided with an upturned finger-piece 26 by which it may be manipulated when it is desired to adjust the position of the typewriter forwardly or rearwardly or to remove it from 100 the support. A forward pull of the lock-- plate against the action of sprino' 20 causes the cam-slots 18 engaging t-he studs 17 to withdraw said lock-plate from engagement with the buttons at that side of the machine, and releases the locking action of the parts. It will be seen that the lock-plate automatically releases by a forward movement ofthe machine and the machine can easily be removed from Ythe support.V

Obviously, when the llock-bar is forced into engagement with its corresponding butt-ons,

those at the opposite side of the machine' will be forced into intimate engagement with the ledge-portion of the rail 11, as this ledge and the lock-bar are in coincident horizontal planes. The ledge-portion of the left-hand railr 11, at the rear, is formed with a stop 27 against which the rear button 22 on that side ofthe baseboard will impinge to limit the backward travel of the machine over the support, and this ledge-portion is also rounded at the front, as at 28, and the front end of the lock-plate 19 is likewise rounded, as at .29,.t-hese rounded portions, collectively', forming ay guide-throat 30 between the rails with which the grooved buttons contact when the machine-is pushed baclwardly to a desired positionand automatically locked in such position.

In the introduction of a portable machine baseboardl into the throat 8O between the two ledges, the machine may be tilted slightly to align the two rear grooved buttons tothe front ends of the ledges 15 and 19, and` after drawing the finger-pieceV 26 forwardly to spread the ledges, the machine may be pushed rearwardly upon the ledges, and, when all four buttons are engaged, the finger-piece 26 is released to its spring 2() to lock the baseboard with the four buttons clear of the deskboard 10. o

Variations may be resorted to within. the scope of the invention, and portions of the improvements may be used without others. Having thus described my invention, I claim:

i 1. The combination with a typewriterbaseboard, of grooved buttons, secured to said baseboard, parallel rails to be secured to al desk to extend-rearwardly'thereon, one for engagingthe grooved buttons on one side of the baseboard, a plate slidably mounted on the other rail forengaging the grooved but'- tonson the other side of the baseboard, and means co-operating with the plate to lock the baseboardwith the typewriter in an adjusted position along said'rails relative to the fro-nt ofthe desk. Y

2. The combination with a typewriterbaseboard, of a plurality ofV grooved buttons carried thereon, a support for the baseboard including fixed parallel rails, one engaging the grooved buttons on one side of the base- Y board, a slide plate mountedonthe `opposite rail, and a spring for causing said plate to Y engage the grooved buttons on the other side of the baseboard to lock the baseboard in an adjusted position along the rails.
