DETACHABLE COUNTER BRACKET FOR SUPPORTING FABRIC PUTI'N'G MACHINES.

application med my 19,

' This invention relates to an improvement in counter arrangedbrackets for the support of computing machines and the like used in connection with lthe measuring of fabrics, and'ha-s for its primaryobject the. purpose of providingan improved detachable securing v.arrangement for demountably securing a bracket at different places on av counter.

Another object of the invention is in pro erable with the automatic'securing means.

Other and further objects will appear in the specification and be specifically pointed out in the appended claims, reference vbeing had to the vaccompanying@ dra'wings, exeml plifying the inventiomand in which z- Figure 1 is a sider elevation of acounter having its intermediate .portion broken away and showing a series of elements .secured to the edge of the counter with-which this improved bracket is Y(io-operable, and showing the improved bracket in (zo-operation with one of the elements.

Referring by numerals to the accompanying drawings 1 designates. a counterhaving a top 2 and secured to an edge of'sadd .top are a series of stationarily held base members 3, each of said members 3 being pro' vided with a pressed out portion 4 which'is formed intermediate of its ends and arranged parallel to thev edge of thev counter top,

said portion 4 being provided witha receiv- A CORPORATION OF MISSOURI.

ing opening 5, from which an angular dis# posed slot 6 is extended, the upper edge of said slot forming .a cam surface?. the lower edge of said slot being provided with a series of ratchet teeth 8.

The vsupporting bracket. 9 which is co-operable witheach-of the base members 3 is comprised of a vertically extending portion 10 in which is formed a vertically extendingv cylinderljl which is closed at its lower'end as. designated at 12,. and formed integral with said extending portion 10 is a base portion13 having an integrally formed depending portion 14, said portion 14 being'devpended below the top surfaceof the counter 2, thereby providing a housing 15. y

Formed within said housing are a pair of inverted seating portions 16v and secured .against each of said seating portions by a ,respectlve screw 17 is an angularly disposed portion-.18 of a triggerv carrying plate 19,

and horizontally extended from said platel is a oin 20 bearing a trigger 21.`

,The trigger 21'is provided with a pawl 22, said pawl extending through an opening 23 which is formed in the plate 19, said trigger being-borne on the outside of said plate, as

shown inFigs. 2 and 4 andis provided with a depending finger engaging portion 24, there being a coil spring 25 for normally holding the pawl 22 in engagement with the ratchet lteeth -8- which are -formed on the edgeof the slot 6 of each respective. base member 3, thus preventing the pin'2() from `being disengaged from the slot 6.

As already mentioned inoneof the y0bjects of this invention', -this improved detachable bracket is for the support of a computing and vmeasuring machine, and asV designated in the drawings as 26, saidA machine having a base 27 from which is depended a shoulder 28V and ,extending downwardly from'said shoulder isa projection 29 which is secured by a pinl 30 to the upperfend vof a plunger 31 having a closed lower end 32.

The tubular member 31 is` adapted to be vertically held within the Acylinder' 11 Vof the bracket 9, and secured to the closed end 32 .of said tubular member 31 by the bolt 33 is a packingelement inthe form of an inverted Mruisumrm` .um cou- I leather cup 34 which is adapted to peripherally engage the wall of the cylinder 11, thereby providing a compression compartment 35 beneath said cup 34.

The tubular member 31 is provided'with a vertically extending slot 36, and extended through said slot and through the wall of the cylinder 11 is the threaded end 37 of a clamping member 38, said member 38 being provided with a handle 39.

The threaded end 37 of the member 38 is engaged within a clamping block 40, said block being located within the tubular member 31, so that when the member 38 is manipulated towards tightening a portion of the wall of the tubular member 31 will be clamped between said block 40 and a portion of the wall of the cylinder 11, as shown more clearly in Fig. 2. y

It is to be notedthat each of the base members 3 is provided with an edge 41 which is arranged on a planeabove the top surface of the counter top 2, said raised edge being for the purpose of receiving the under sideof eachV of the angularly disposed portions 18 of the trigger carrying plate 19, when the bracket 9 is being mounted into position upon the counter, and forpreventing the lower end 42 ofthe vertically extending portion 1() of the bracket 9 from engaging the surface top of the counter, a roller 43 is secured beneath the base portion 14 of said bracket.

In the mounting of aidevice of this improved character to a counter for the purpose of supporting the computing machine 26 thereabove, the pin 44 bearing the shoulder 45 which is horizontally extended from the trigger carrying plate 19 inwardly thereof, is engaged into the receiving opening 5 of the slot 6, and in which the bracket 9 is borne to the left and permitted to rest upon the counter top 2, the roller 43 directly engaging said counter top while the portions 18 of the trigger plate 19 will slidingly rest upon the upwardly extending edge 41 of the base member 3 to which the bracket 9 is being secured.

The leftward sliding movement of the bracket 9 to the base member 3 upon the introduction of the pin 44 within the slot 6 as just related, will cause said pin to bear againstthe cam surface 7 of said slot 6, and since said cam surface is inclined downwardly the bracket 9 will be drawn tightly against the top of the counter, and while said leftward movement of the bracket is taking place the pawl 22 of the trigger 21 will automatically engage the ratchet teeth 8 of the slot 6 thereby preventing retrogade movement of the bracket 9. and in which said bracket will be locked in a secure position to the base member 3 of the counter.

If itis desired by the operator to vertically adjust the machine 26, the handle 39 in which the clamping block 40 Ywill be drawn against a portion of the wall of the tubular member 31 thereby/clamping said wall portion-against a portion of the wall of the cylinder 11. l

In the event that the machine' 26 is tobe lowered, after the clamping member 38 has been manipulated towards loosening, the machine V26 can not be lowered with rapidity on account of air being confined withinnthe compartment 35 which is formed at the lowerendof'the cylinder 11, and in'which the'air will be permittedv to escape slowly through the small vent opening 46 which is provided in the closed'end12'of said cylinder, the confined or trapped air -withinsaid compartment 35 serving as a cushion to the descending'tubular member 31 ofthe machine 26. VThe purpose of providing the cushioning means as just described is so'that accidents will be prevented to portions of the hands or fingers of the operators in the event that the hands are allowed to be positioned between the shoulder28 of the Inachine 26 and the top of'the extending portion 10 of the bracket 9.

A demountable bracket of this improved character is essential in connection Awith computing and measuring machines as it is quite often desired lto'shift such supporting brackets to different locations on a counter,

and when it is' desired to detach or dismount pressed upwardly, ywill release the pawl'portion of said trigger from engagement with e the ratchet teeth 8 of thefmember 3, thereby permitting the bracket 9 to be moved to the right so that the pin can be disengaged from the slot 6. i

What I claim is f 1. The vcombination of'a counter and a detachable bracket therefor, a base member borne bysaid counter having a: horizontally inclined cam surface, said brackethaving a projection for horizontal co-operation with said cam surface of said member horizontally disposed teeth provided on` said member, and a locking element borne by said bracket for fro-operation with said teeth of said member. Y

2. The combination of a base member and a detachable bracket therefor, said member adapted to be secured to anv edge of a counter and provided with a horizontally inclined slot, a series of teeth formed on one edge'of said slot, said bracket having a horizontally extending pin which is adapted to be slidingly engaged in said slot of said member,

and means carried by said bracket co-operable with the teeth of said member for preventing said pin 0f said bracket from being disengaged from the slot of said member.

3. The combination of a counter and a detachable bracket therefor, horizontally inclined cam means borne by said counter and vmeans and said bracket, and means carried by said bracket for engaging with the teeth of said cam means. v
