To all whom t may concern:

Be it known that we, EDWIN W. ROGERS and CHARLES C. CHAPEL, both citizens of the the purpose of raisingor lowering the as semblying elevator efficiently, whereby lost motion is overcome, due lto movement back and forth of the operators hands from the keyboard to the usual standard hand controlled lever, which raises and lowers the assembling elevator. Hence, .our improve-V ment will leave the' mind and the .hands of `the operator free to perform the ordinary p keyboard functions, and judgment or precaution can be dispensed with in raising and lowering the elevator, due to the fact that the problem, as we have solved it, is an arrangement of la `foot controlled means whereby the elevator is raised or lowered and cushioned at the end of movements.

Another object of our invention is to connect the assemblying elevatorwitha footv treadle operating means, having some form ofinterposed cushion wherebythe starting `inovementand the finishing movement ofthe i assemblying elevator is gradual or retarded,

means interposed therein, whereby whenthe elevator is full down, the coil spring is compressedfandrwhen full'up, the same is again y compressed .to thus absorb the shock. In

`'other words, .when in a machine equipped with our invention, the elevator is in its upward movement, it starts with a short leverage and .thereafter increases and develops speed by action on a long lever until the ele- Y vater reaches approximatelythe full vheight Aof 'its travel, at which time "it engages' the standard stopandv shock of this sudden stop is absorbed a yield ofthe spring mechanism.

With the above 'and other objects in view, the invention consists in certain peculiarities of construction and combination of parts, as

are hereinafter set -forth with reference "to the accompanying drawings and `subsequently claimed.

In the drawings: Y Figurefl represents a fragmentary face view -of'a. standard linotype .matrix assembling device orelevator, having attached thereto a :foot actuating mechanism embodying the featuresof ourinvention, therelevatorbeing shown in anintermediate `position with relationto-its up and downmove-` A 'Y movement, the said stops being diagrammatically expressed.

and in its 'extreme depressed position in dotted lines. Y I

Referring by `characters to the drawings,

A -represents a matrix assembling elevator,

the elevator is controlled by stops, andin Fig. l of the drawings are-illustrated dia- YOne leg C of the machine, in this particular instance, is used for securing thereto a :which-is adapted to reciprocate in a track or i frame B. Thereciprocative movement of bearing bracket 1 by suitable set screws, ity i being understood, however, thatwhen 'our device is used as a. built-in structure, a suitable'bearing bracket maybe cast from the base of the machine. The Vbearing bracket 1, has journaled therein a rocksha'ft.

.2, one end of which has secured thereto a foot'trea'dle' 3, whereby the shaft maybe "rocked in either direction." The other end 'of the shaft 2 is formed witha right angleextension ad 2 to which is secured an a er-V.k

tured ear 4 that extendsat a right .angle to the foot. The earhas fitted` therein aheaded bolt 5, Awhich boltalso passes through an apertured `foot 4 of a rock arm 6. The rock armis arran ed to nest snuofl a ainst one e:Y n v wall of the pad 2', whereby it is guided and its foot terminal 4 is held, under normal` conditions, in snug contact with the ear /lof the pad by a coil spring 7 which surrounds the bolt 5 and is interposed between the foot 4 and a washer 8 that is adjustably confined by a nut 8 in threaded unio with the upper end of the bolt 5.

The forward end of the rock arm 6 is pivotally connected to a link in the form of a bell crank lever having a short arm 9 Aand a long arm 9. The short arm of the bell crank is arranged to travel in an arc of a circle, parallel with the rock arm 6, the said short arm 9 being limited in its movement in either direction by stop lugs 10 10, which lugs constitute part of a bracket that is adjustably secured by a bolt 11 to the'V rock arm 6. Hence, it will be seen that by adjusting the bracket and its associated lug toward or away from the fulcrumrpoint of the bell crank lever, its swing upon saidfulcrum point may be predeterniiningly controlled. The upper end of the long arm 9V of the bell crank lever has fitted thereto an adjustable strap portion 12, which strap portion is held against movement after a predetermined adjustment' by a clip 13 thatv surrounds the companion parts of the bell crank lever, the Vsame being locked by a set screw 13. Hence, the long arm of the bell crank lever can be lengthened or shortened for adjustment to the various conditions of machines, to which the devices apply.

In this exemplification of my invention, as j shown in Fig'. l, a link C has one end connected to the assembling elevator, andthe other end connected to the upper end ofthe strap portion l2 of the bell crank lever by a set screw 14. This link C or its equivalent, in a standard machine, is employed for connection to a hand controlled lever not shown, whereby the elevator is raised or lowered.`

Attention is directed to the fact that the spring controlled hinge joint between the trol hinge joint between the arm and rock.

shaft closes, it being understood that it is normally brokenwhenpthe previousdown stroke of the elevator was completed, due to the fact that the` elevator was positively stopped in said down movement.

Hence, the firstimpulse of the operator in lifting` -will be absorbed so as to preventa sudden shock upon the elevator,.and thereafter the elevator will be lifted gradually,

as the rock arm rises until such time as the elevator comes to a point near the finish of its lift, at which time the short arm 9 of the bellcrank will engage the stop 10 of the rock arm, and thus the rock arm and bell crank being locked together, the spring will now come into play as a cushion, and the hinge joint `will be broken slightly, as

,tive stop or bumper a. This cushioning of the stroke is accomplished by the shock absorbing spring and the jointed rock arm connected between the rock shaft.

In practice, by ,actual demonstration, it has been foundthat by the use of this foot control mechanism, under normal conditions,

the speed of the operator can be increased j 30%,-due to the factthat the hands of the Voperator, are entirely free at all times to manipulate the keys, and his mind can be at all times concentrated upon the keyboard and work.k Under the old conditions, where a hand lever was used, operators found it necessary to leave the keyboard anduse one hand for lifting orlowering the elevator, and the other hand was utilized to grasp the elevator and retard it in its movement in j either direction. All of this hand work has Awhile we. have shown and described one specific means of carrying out our invention,

.we may, without departing from the spirit of the saidinvention vary such details within the scope, of the claimsfas they may be hereinafter interpreted by thoseskilled in the art. i

We claim:
