bottom of the finger tip. This method of inking the finger tips is very unsatisfactory because the slightest movement 'ofthe finger with respect to the inked surface will cause, the entrance of ink .into the depressionsbetween the lines of the finger to be reproduced, and the prints obtained from such improperly inked finger will be 'smudgy and will not suflice, for purposes of classification or identification. It istherefore quite often necessary to. repeat the inking process several times before clear prints are obtained; 7 .Another disadvantage of the present manner of inking thefinger tips is that .the same have to be rotated with respeetto the inked surface so :as to also. apply the ink to, the sides of the finger tips,.which is necessary to produce ,proper prints for identification purposes. Such turning of the ,fingers isjvery inconvenient for a person whose fingerprints are taken, and the possibility .of moving the finger with respectto the inked surface during such turning. operation is considerably increased, so that ink may be forced into the depressions between the lines of the finger as abovementioned, andthe results ob,- tained in. reproducing the lines upon a Bertillon card or the like will not be sufliciently clear for the above purpose. a t p H The present invention has been devised to overcome the above .difiiculties and. provides a mechanism for theinking of fingertips prepara tory tothe making of impressions therefrom, wherein the likelihood of movement of the finger with respect to the. ink carrying surface is substantiallyeliminated. V I
The present invention provides a finger inking apparatus comprising a flexiblemember upon which fingerprint ink is evenly applied sov that, when the finger tip is placed'uponthe flexible member and the same is depressed, the bottom as well as the sides of the finger tip will be properly inked without the necessity of turning the" finger with respect to the inking surface. e
Other and further objects ofthe invention willbecome apparent from the following ,de'scrip tion and drawing, inwhich- 55 Figure 1 is a front view of the g r i k shown ratus, similar to Figure 1, the flexiblegmember,
however, beingshown in depressed position.
Figure. 5 is a perspective. view of the finger inking apparatus .of the present invention.
Figures fi and? are views illustrating an ink supply mechanism which may be advantageous- ,ly used in connection withtheprese'nt invention.
Figure 8 shows a, modified structure of ink supply .mechanism. V .Referring now to the drawing, and particularly to Figures 1 and5, l indicates a housing or casing within which a -V-shaped frame member 2 is positioned and secured to. thebottom 3 of the housing bytheuse of any convenient fastening means 4. Adjacent the rearwall 5 of .the
housing I- isa, supporting plateJB which is secured to the saidhousing by means of'screws 1.
Interposed between the vl-shaped frame 2 and V the supporting plate 6 is a .plurality ofru'bber or composition rollers 8, 9, and I2. The rollers a, 9 and IZ'are mounted upon shafts l3 which are supported within holes or bearing portions 14 of a the V-shaped member 2 and platefiwAdjacent the rollers 8, 9 and I2 are rollers l5, l6 and I1, ,movably arranged within the V-shaped frame 2 and platefi and urged toward the rollers 8 9 1 and I2 by means of coil springs IS, l9 and,
The shaft 26 of roller l2 extends rearwardly of the plate 6 and is provided with a. beveled gear 21 keyed to the same and in operative engage-ment with a corresponding beveled gear' 2 8 keyed :to a turning or crank shaft129 Shaft'29 is rotatably mounted within the side wall la of the housing I and a bearing member 30, secured to the back wa1l'5 of the housing, is providedifor .is pressed downwardly in the direction indicated 'by thearrow in this figure, to a position as shown supporting the end of shaft 29 adjacent. the beveled gear 28.
The housing I is preferably provided with a front wall 3| provided with outwardly extending portions 32 for housing the end portions of the roller shafts extending forwardly of the V-shaped plate and springs |8, I9, and 20 so as to permit their free movement, as will be explained later on. A cover member 33 is secured to the housing I and is hinged thereto in such a manner as to permit access to the flexible or ink carrying member 25, for'purposes explained hereinafter.
From the above it will beseen that the flexible or ink carrying member is held in frictional contact with the rollers of the-inking apparatus of the present invention, and-upon rotation of crank shaft 29 and roller '|2, shifting of the endless flexible member 25 in the direction indicated by the arrow in Figure 1 will be accomplished.
In the operationof the device, fingerprint ink is applied to the roller 9;'uponrotation of the crank shaft 29 the flexible member 25 is shifted in thedirection shown by the arrow in Figure l, and the fingerprint ink is evenly distributed over the outer surface of this member. The roller 9 therefore functions as an ink applicator which spreads the ink thinly over the surface of the flexible member. a
,pers'oriis 'placed upon the flexible member 25,
as clearly seen in Figure 5,'whereupon the finger in Figure 4, and the rollers l5 and I6 are thereby .forced downwardly and the flexible member 25.
folds around the finger 34 and applies the ink to the bottom and sides of the same, whereupon the properly inked finger is then removed from. the device by raising the same upwardly,'and impressions of the finger tip may now be taken in the usual manner. 7 V
The front plate 3| of the finger inking device isprovidedwitha V-shaped cut-out portion 3|a which conforms to the configuration of the frame ,2 so as to'permit the downward movement of the finger .as explained in regard to Figure 5. The impressions of the finger tips inked in the manner heretofore described may be taken with a device of a construction similar to that described herein. However, instead of the member '25, an impression member, preferably made from paper 'or like impression material, may be arranged between the composition rollers. In such instance of courseit would be necessary to have one apparatus for inking the finger tips and another apparatus with the impression reproducing member for the reproduction of the fingerprints.
It will be seen therefore that in this manner a perfect inking of the finger tips may be obtained extends substantially over the Width of the side wall la and into the compartment 38 betweenthe rear Wall 5 of the housing and plate 6, The exthe roller:9 and the member is then shifted to a position so that the extension 36 and wick 39a are within the compartment 38 and out of contact with roller 9. Upon rotation of the flexible member 25, ink will be applied from the roller 9 to the member 25 and will be evenly distributed thereonin the manner outlined above.
When the apparatus is out of use, the cover 33 is applied and entrance of dust to the ink.
carrying memberiseffectively prevented.
From the foregoing it will be seen that I have devised a novel inking apparatus which eliminates thedisadvantageous features of presentday devices used for the purposes mentioned hereinbefore, and which permits inking the fill ger tips of a person preparatory to taking impressions therefrom, in a very efficient manner,
and wherein the likelihood of smearing the ink into theridges between the lines of the fingers has been substantially eliminated.
Figure 8 shows a modified construction of ink supply mechanism as may be preferably used in connectionwith fingerprint ink of a paste-like consistency. 1 The tubular portion 4| through slot 31 of the casing into close prox imity with roller 9, and is held in proper position with respect to' the casing by washers 42 and 43 soldered or welded to the portion 4| in a manner clearly illustrated in Figure 8. member 4| is provided with a threaded portion 44 cooperating with athreaded portion 45 of the cup'member 46. When the supply mechanism is filled with ink and the cup 46 is screwed upon member 4|, the ink paste will be forced against a the roller 9. The ink supply mechanism.may be shifted out of contact with roller 9 in the same manner as described in connection with Figures Sand '7.
Having thus described my invention, what I claim as new and desire to secure by Letters member, resiliently mounted spaced supporting means forthe flexible member, between which the flexible member is depressible, ink applying means associated with said flexible member, said flexible. member being movable away from the inking means when the former is depressed and means for shifting the flexible member and rotating said supporting and applying means to thereby transfer ink fromthe latter to the flexible member.
