, ADJUSTABLE STAND.

Application led March 23, 1927.v `Serial No. 177,807.

This invention relates to adjustable stands and more particularly to stands for holding a .rivet cutter during the cuttingof rivets on a steel railroad car and similar work. V

A primary object of the invention is to provide means for relieving the operator, When riveting, avoiding` the necessity of holding the rivet cutter continuously and which provides for the easy and reliable performance of the work, and avoids breakage of the chisel in the cutter, which frequently occurs when the cutter is manually held.

Another object is to provide a standof this character which enables a rivet to be cut on top at a much higher elevation'than can be vdone when the cutter is held by hand, andV which permits a rivet to be much more easily cut from underneath,'because of the fact that the operator can hold the chisel to the rivet,

the holder for the cutter being adjustable atv any desired height.

Another object is to provide a device of this character equipped with means for holding the chisel at a proper angle for cutting;

Still another object is to so construct a stand of this character that it may be held rigidly by means of the operator standing'on a platform provided for this purpose.

In carrying out these objects, the invention is susceptible of modification without departing from the spiritor sacrificing any of the advantages of the claimed invention; there beingshown in the drawings for illustrative purposes', a preferred andpractical form, in w ich :v I

stand intermediate their length, and a lon? gitudinally disposed board or bar 3 is fixedly secured'to the tie bars 2 for rigidly holding the members of the stand together. l This bar 3 projects at its ends beyond the end tie bars 2 and is slotted yas shown at 4 for the passage In the embodiment illustrated the stand therethrough of rack bars 2O and forms a guide for said bars. It will thus be seen that this member 3 performs a double `function of a tie bar and a rack bar guide. v

A plurality of spaced vlongitudinally eX-k tending bars 5 connect the legs lat the ends of the stand and aredesigned to strengthen and rigidify the stand in addition to forming means for supporting one end of a platform 30 and as supports for the rivet; c utter as will be presently more fully described.

Four of these bars 5 are shown although obi viously any desired number may be used.

Arranged above this group of bars 5 is another bar y6 tosupport the rivet cutter.'

y The top 7 of this stand is fixed to the converging upper ends of the pairs of end legs 1 and is composed of three boards or sections 8,9 and 10, bolted together and tothe legs 1. Mounted on the top 7 is an auxiliary top -11 also composed of three boards orv sections 12,A

13, 14, the central or intermediate memberV of both lof thesetops beingpreferably made of hard wood. This top 11 is connected with the ratchet bars vor levers 20 which are equipped on their inner edges or faces with a plurality of spaced ratchet teeth orrecesses 21 designed to engageV the ends of the member 9V which terminates short of the members -8 and 10, the projecting endsl of the later having 'l bolts 7 a extending through them :and spanning the space'between them and "infwhich space the bars20 operate. By making this member 11 adjustable in the manner aboveA described, the rivet cutter restingthere'on may From ther above descriptiomit will be lseen.

that the rivet cutter may be used by resting it on the tops of bars 5, or on bar 6, or on either of tops 7 or 11, andas abovedescribed, the top 11may be adjusted to support the cutter at an lelevated position above the stand Proper. j

The platform show-n at 31 and at the junction of said reduced portion with the body 2 of the platform has transversely arranged cleats 33 and 34 secured'toV the upper .and lower faces ythereof and which project beyond the ends of the reduced portion 31 and form shoulders or abut- 30 has one end-reduced as ments to engage-the 'legs 1' at opposite ends 'of the st and to limit linsertion of the extension 31 between two of the bars 5, said cleats being.

lng of the platform on the stand. At the outer end of this platform are legs 35 which are designed to support the platform at this point. This platform is designed as a support for the operator whoin turn by his Weight holds the stand in rigid position preventing all danger of its tipping or tilting while the rivet cutter is in operation.

A lock for the extension member 11 is provided in the form of a keeper y22 mounted on one .end leg l as shown in Fig-.3, which is designed to receive a latch 23 pivoted at one' end to the other end leg. This `latch when swung into operative position spans the space between the two end legs and holds the member 20 with'one of its notches or teeth 2l en- Vgaged with the bar 9.oftop 7 and thus securely locks the extension in adjusted .position. To release the members 2() for wthe adjustment' of the extension the latch is swung lout of engagement with `the keeper 22 land these members 2O owing to their slotted connection with the members l2 and la of top 1l and -with board 3 maybe swung out to disengage the notches 2l from bar 9 and thuspermit top l1 to be .raised or lowered, as desired. This slotted connection of members 2O with the top l1 also provides a pivotal connection at these points so that one of the members 2O may be raised or lowered independently of the other to vary the angle or inclination of the member ll when it is desired to support the rivet cutter at such an angle.

From the above description it will be seen that this stand is exceptionally well `adapted to form a rest or support for arivet cutter While cutting rivets on a steel railroad car or any other similar work, it being vwell known that such cutters are heavy cumbersome tools and which, when held manually, quickly tire. the operator and prevent him Y from accomplishingthe cutting operation in Vthe' most skilled manner. The mountingy of .the rivet cutter on a stand provides for the steady holding ofthe chisel and thereby prevents danger of breaking it.

Without further description it is thought that the features and advantages of the invention will be Vreadily apparent vto those skilled in the art, and 'itwill ofcourse be yunderstood from changes in the form, proportionand minor ldetails Vof construction may be resorted to, without departing from the spirit of the invention or its scope asclaimed.

1. A holder for rivet cutters and the like comprising a stand having a plurality of cutter rests' and'means pivotally lconnected with one of said rests for adjusting itvertically at an angle to vary the cutting angle ofr the tool mounted thereon.l

2. holder for rivet cutters andithe'flikeV comprising a stand including pairs of connected end legs, those of each pair diverging from their upper towardtheir lower ends, top bars connecting thel upper ends of said legs and spaced transversely from each other with the vendsthereof extending beyond the outer edges of the legs, transverse members connecting said extended ends to provide a space between them and the legs, an auxiliary top .mounted on said main top and movable verticallyrelatively thereto, pivoted levers depending from said auxiliary top and extend-` ingl through the spaces between the transverse members and the legs, said levers being provided on their inner edges with Vspaced ratchet notches, a plate extending longitudinally of said stand between the legs lthereofand having longitudinally extendingopenl ings in their ends through which said levers extend and are guided, said openings being larger' than the legs to permit the free swinging movement of' said levers to provide for the engagementof'the ratchet notches with the walls of the inner ends of said openings whereby the auxiliar-y top is held in adjusted position, and means for locking said levers engaged with said plate.;

3. A holder for rivet vcutters and the like l comprising a stand including pairs of con- A versV depending `from' said auxiliary ,top and extending through ythe spaces between the transverse members and vthe legs, saidV levers being provided on their inner edges with able vertically relatively theretmpivoted lespaced ratchet notches, a plate extendingfV longitudinally of .said stand between the glegs vthereof and. having :longitudinally: extending openings in their ends throughwvhich saidlevers extend and are guided, said openings being larger-than the legs to permit the free swinging movement of ,said `levers to provide for the engagement of thei ratchet notches with the walls of the inner ends'Of said openings. whereby `the auxiliary top is held in adjusted position,'and a latch member pivoted on one of the legs of one pair vand adapted to swingacross the outer faceof the cooperating lever and means carried by the other leg of the pair for engagementy ,with said latch vto hold the-lever in adjusted position.
