- Application August 5, 1949, Serial No. 108,739
ject to provide, a portable, fingerprinting machine of novel construction; the machine being compact, relatively light weight, easy to erect from a knocked-down, carrying position, and
convenient to use.
A separate object of the invention is to provide a fingerprinting machine which is arranged for multiple adjustments with respect to the person whose fingerprints are to be taken; it being unnecessary for theperson to move or change position during the fingerprinting process as the parts of the machine are adjusted relative to said person.
A further object of the invention is to provide a fingerprinting machine, as above, which makes possible the convenient taking of fingerprints with the persons arm extended substantially straight forward, as is desirable to the production of eifective prints and which requires rolling of each finger at a predetermined point on the record card; and similarly to accomplish proper fingerprinting of persons whose fingers may be crippled, crooked, or otherwise deformed.
Another object of the invention is to provide a fingerprinting machine which provides a novel assembly of ink platens arranged to prevent dirt and dust from accumulating on the p'latens and keeping the ink moist when the machine is not in] use, thereby avoiding the necessity of daily cleaning of the platens.
The machine is also provided with effective artificial illumination arranged, in a manner which facilitates proof reading of the print which remains on the finger inking platen after a persons finger is rolled thereon.
An additional object of the invention isv to provide a fingerprinting machine which includes a novel detachable clamp for holding the fingerprint record card onthemachine during printing of individual fingers; such clamp-when multiple fingerprints are taken-being easily detachedandthen suspended in a readily accessible manner from the machine for subsequent use. It is also an object of the invention to provide a fingerprinting machine designed for ease and economy of manufacture; the machine being sturdy in construction and stable when in use.
Still another object of the invention is to provide a practical andreliable fingerprinting machine andone which willbeexceedingly effective for the purpose for which it is designed.
These objects are accomplished by -means of such structureand relative arrangement. of part 7 Claims. (Cl. 414) This invention is directed to, and it is an obas will fully a pear by a perusal of the following specification and claims.
In the drawings:
Fig. 1 is a perspective view of the fingerprinting machine as set up for use.
Fig. 2 is a crosssection on line 2-2 of Fig. 1.
Fig. 3 is an enlarged fragmentary sectional elevation of the turnably adjustable connection between the tripod stem and the table top.
Fig. 4 is a sectional plan on line 4-4 of Fig. 3.
Fig. 5 is a cross section of the table top taken on line 55 of Fig. 1.
Fig. 6 is an enlarged fragmentary plan view showing particularly one of the separable hinges which secures the finger inking platen to the table top.
Referring now more particularly to the characters of reference on the drawings, the novel fingerprinting machine comprises a tripod, indicated generally at l, which tripod is of an adjustable, folding type. A vertically adjustable stem 2 projects upwardly from the head 3 of the tripod; such stem 2 being adjusted by a crank 4 which actuates a rack and pinion mechanism between said head and stem, the rack being on the stem and indicated at 5. 7
Above the tripod I and stem 2, the machine includes a table top unit, indicated generally at 6; such table top unit being rectangular in plan but elongated transversely. I
The table top unit 6 comprises a pair of side by side, longitudinal sections; the inner or back section, indicated at I, being stationary and I horizontal, while the outer or front section, indicated at 8, is vertically tiltable. The stationary section 1 and the vertically tiltable section 8 of the table top unit 6 are connected together, at adjacent edges and for the full length thereof, by a piano hinge 9.
The above described table top unit 6 is rotatably and removably supported on the upper end of the stem 2 as follows:
At its upper end the stem 2 is formed with an upwardly projecting trunnion [0 having an enlarged stop collar l I at its lower end. The trunnion [0 projects, in relatively turnable relation,
into a vertical-axis, clamping collar l2 which is secured in connection with the bottom of the With the above mounting arrangement between the stem 2 and table top unit 6, the latter can be turnably adjusted about a vertical axis.
The section 8 of the table top unit 6 is tiltably adjustable by means of the following mechanism:
Substantially centrally thereof the stationary section I is provided with a finger knob It accessible from. above. said. section, and said. finger knob is secured to the. upper end of a depending spindle II which projects some distance beloW said section I, bein turnably supported in a lower horizontal leg [8 of a depending mount I9.
A worm 20 on the spindle I 1 meshes with-asegmental gear 2| which is formed as one. end of a forwardly projecting lever 22.
mount 19 for vertical swinging motion.
A link 24 pivotally connects between the forward end of the lever 22, as at 25, and a pivotal anchor point on" the underside of' the tiltable section 8, as at 26;
By rotating the finger knob= t6, with resultant motionof theworm: 20 and segmental gear 2|, the lever 22 and 24 act to-t'iltabiy'adjust the section B upwardly or downwardly; atthe selection ofthe operator.
On the lefthand halves thereof the-stationary section Tand the tiltable section 8 of the table top unit 6" are fitted with rectangular; metallic platens 27- and- 28, respectively; such platens being preferably of stainlesssteel. The platen 2-1 is for the purpose of initially preparing. or spreading the: printing ink, while the platen 2.8- espe'ciall'y the outer portion thereof.is. for. the finger inking step of the fingerprintingv process; thepersonwhose fingers; are: to be.v printed standing in front ofthe tabl'e top' unitBr-irrfacing relation thereto.
The platen 21- is removably' held: in. place on the" stationary sectiorr I by headed hOIdrdQW-H pins 29 along opposite side: of said; platen. The platen: 2:! is removable: from the headed. hold The lever 22' is' pivoted, intermediate its ends; as. at 23, to. the":
4 1 when the machine is set up but not immediately in use, the platen 28 is swung or folded over on its hinges to closely overlie but not actually contact platen 27; the transverse upstanding lip on the platen 2'! at is inner end being engaged by platen 28 to prevent such contact.
While his folding over may be performed when section B is upwardly tilted as indicated in Fig. 5, it ispreferably carried outwhensectioiml is flat, since a closer approach of the platens, with a smaller air circulating passage therebetween, is thus provided.
The table top unit 6 is illuminated from above by anadjustable light fixture 35, with suitable redown pins 29: by sliding said-platenv lengthwise in V a. laterally outwardly" direction the. platen being 7 slightly tapered to normally wedge against the pins?- 2 9 but readily freein therefrom: when slid as above;
The platen. 28-1 is held. irr place. on the tiltable section 8 by transversely spaced: hinges 33 connected betWeenthe-inner longitudinal edge of the platen. 2'8 and said: section-- 8;.
In order topermit of. removal ofthe platen 28 from. the section..8, as is desirable when the machine is; knocked. down. and placed in a carrying case for transport, thehi-nges 3!! are. each of separable: type-,including, a pull-out hinge pin: 3 I.
.By' shitting. the platen: 28= laterally toward: the
adjacent end of the table top unit.- tc the pins; 3-! pull out and the hinges 30 separate.. .In order to prevent such occurrence under normal conditions, a relatively short Stop: pin 32 upstands from the section 8 for normal. abutment by the laterally outer end of. the. platen 28:. To permit escape from said stop pin 32 the platen 28' is merely lifted slightly and then shifted laterally outwardly to separate the hinges 3E.
The portion of the tiltable section 8 directly below thecen-tralouter portion of the platen 28 is cut away, as at 33, to permit a persons hand tobe positioned close to the outer edge of said platen 28' for the inking of a finger or fingers thereon; such outer edge being rounded, as at at.
In order to prevent the fingerprinting ink on platens 2'! and 28 from becoming dirty or'dry fiectoras shownadjustably mounted on the upper end of a post 35 which is detachably supported in-a socket 31 on the stationary section i between the platen 2? and the rear edge of said section toward the left hand end thereof.
In addition to illuminating the entire table top unit: ii the lightfixture 35f canbe set so, that the operator can readily see orproofread the fingerprint. which shows'on the finger inking platen 28; with. each use thereof. Thus, if the fingerprint is not'complete at the time of inking, the operator can again ink the finger before the print. is taken, soas: torsave time;
A fingerprint record card holding box or bin 3& issuspended from the stationary section I and opens through a slot 39- in theright hand half thereof; such card box being separated into front and rear compartments by a partition 40. One half of the card box is adapted to hold new or unused cards, whereas the other, half is adapted. to receivecards upon which a fingerprint record has been made.
A utility drawer 41 is suspended from the stationary section. 1 below the; platen 21; such drawer being adapted to hold the-fingerprinting supplies, such as: the.- brayer, spatula, tube of printing; ink, wiping cloths for the platens, etc.
The outer edgeportion ofthetiltable section 8.- to thev left of the finger inking platen 28 is the-point on the machine where the actual fingerprinting is accomplished; such portion of the section B.being. adapted to be straddled bya generally U-shaped-,- transversely elongated card holding, clamp 42- of spring metal. Such clamp has laterally outwardly flaring flanges 53v on its inner edges to facilitatestraddling engagement of the clamp over the section 8. from its outer edge; the latter being rounded, as at 44, to permit a fingerprint record card to be bent around said. edge with-in the confines of said clamp. In other Words, the clamp 42 serves to properly position the fingerprint record card on the outer edge portion of the. section. 8 for use; such clamp being formed, in the upper part thereof, with a transverse. row of openings 4.5 shaped and spacedto match and, expose the print receiving spaces of the fingerprint record cards.
With the above described fingerprinting machine set up as in Fig. 1, it is used as follows:
Fingerprinting ink is, first spread upon the platen 21' with a spatula, andv is then worked out with a brayer and transferred to the finger inking platen 28; the final and relatively thin course of the ink being applied to said platen 28 adjacent its outer edge.
As previously indicated, the person whose fingerprints are to'be taken stands in front of the machine; 1. e. in front of section 8 facing the same. Without such person being required to moveflthe operator adjusts the machine to the most convenient position byfirst raising or lowering the table topunit 6 to proper height by manipulation of the crank 4, andthen by turn- -ing the finger knob l6 tilts the section '8 to the best working angle. Thereafter, the operator rotates} the table topunit .6 about the trunnion l0, controlling such rotation by manipulation of the clamping screw knob [5, so "as to position the finger inking platen 28 directly in front of the person; all adjustments being made so that such person can conveniently reach the outer edge portion of the section 8 when the-person's arm is extended substantially straight from the With the arm thus extended a finger can be easily placed on the finger inking platen 28 and rolled to properly ink such finger. After this is done the operator turns the table top unit slightly about the trunnion ll] so as to present the fingerprint record card,-as held by the clamp 42, directly in front of the person. The print of the inked finger is then made through one of the openings 45 directly on the fingerprint record card. Here again, as the person's arm is extending substantially straight forward from the body, rolling of the finger, as is necessary for proper printing, can be accomplished with ease, and without much of the labor and manipulation required under conventional fingerprinting practices.
This process of inking and printing, between the platen 28 and clamp-held record card, is continued step by step; i. e. finger by finger until all fingers of both hands have been printed; the table top unit 6 being turned slightly with each such step so as to permit of the best positioning of each finger, without the necessity of the person changing position, for rolling said finger to accomplish a print which includes the necessary deltas which are essential to classification.
After this is done it is desirable to obtain a full print of each hand. To do this the operator removes the clamp 42 and hangs it on a swing bar 46 which depends below the section 8. See the dotted-line position of clamp 42 as in Fig. 2. With the clamp 42 thus suspended in an out-ofthe-way but readily accessible position, the.
record card is manually held atop the section 8 adjacent its outer end for making of the full hand prints.
As each fingerprint record card is completed, it is placed in one compartment of the card box 38, and a new card is removed from the other compartment and afiixed to the section 8' by the clamp 42 for the start of the next fingerprinting process.
By reason of the fact that the section 8 of the table top unit 6 is vertically tiltably adjustable, and as said tabletop unit is rotatable, the operators task is greatly minimized, especially in those instances where a person has fingers which are crippled, crooked, or otherwise deformed. The described adjustments make it possible for the operator to adjust each of the openings 45 to the most convenient point for taking a print, and without attempting to alter the hand or arm position of the person whose prints are being taken.
When the described fingerprinting machine is not in use, the several parts thereof are readily detachable and may be placed in compact relationship in a carrying case (not shown) for ease of transport from place to place.
When knocked down for transport, the tripod I is folded; the trunnion 2 is detached from the clamping collar 12; and'the light fixture post 36 is detached from the tabletop unit 6. The "platens 21- and 28' are re'movably mounted so that they may be taken from the table top unit 6 for cleaning and polishing.
"The described fingerprinting machine provides a most effective, practical, and reliable device-for the making of fingerprint records in an expeditious manner; themachine accelerating the process, and which process has to date been very 'cumbersome'and' slow'in its practice.
From the foregoing description it will be readily seen that there has been produced such a device as substantially fulfills the objects of the invention, as set forth herein.
1 While this specification sets forth in detail the present and preferred construction of the device. still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.
