United States Patent O 3,23-1-,1-69l I-IANDI PRESS- Robert A. Jorgensemlh. Box 245, Edimond's,vWashn Filed Feb. 2'5, 1963; Ser. No. 260,505|` 12 Claims.` (Cl. 227-143) This invention relates to hand presses. It pertains particularly'to hand presses suitable for use' in installing screW-mounted door catches of the type described' in Iorgensen US. 3,06'1,346.

Al'though the press is described with particular reference to'such use, no lirnitait'ion therebyl is intended since by suitable rnodification of theipress head, the press may be used as a convenient hand-operated' press for ay diversity of crimp'ing, riveting, punching, stamping and cutoff applications.

The Iorgensen door catch referred' to above includes a pair of screw-mounte-d, spring-pressed catch arms adapted to receive in releas'able latching engagernent the head of 'a ball-headed screw or similar strike member. The catch is installed by screwing it into the oeiling,` side' wall, or floor of a' cabinet,` or other structural assembly. The strike is inserted between the arms of' the catch with the spur extending outwardly.

The door associated with. the structural 'assemhly is cl'osed against the spur, which penetrates sufiiciently to mark the door. The strikethen. is: removed fromV the catch and inserted in thewmarked location.: on` the door. This sequence of operation requires fperhaps 15 to 30 minutes ofl a carpenterfs time, depending primarily upon the accessibility of? the' catch-mounting location.`

Although the time involved in mounting the Jorgensen catch is even less than` that` required. to mount catches of many other classesri't stillswouldibe desirable toiprovide a tool by means of' which the screws mounting the catch could be` pressed directly into the` stmcturalimember in a single, easily effectuated movement requiringbut a few seconds, 'and it is the general objectiof this'` inventionl to 'provide aihand-operated press which accomplishes this function.

It-is another ofh-jectoffthe present invention toprovide a hand press W'hich -is versatile in its application, not-only to the operation of: pressing `screws or other spurred fastening members intoistructural members, but also-in such Operations as crimping, riveting, punching', stamping and Cutting work of various categories.

Stilla further object-of`` the in'vention is; thei'provision oft a hand press adap'ted; particu-l'arlfor` pressing'screwmounteddoor' catches` into struetur-almembers,- and: characterized byu the: following` advantages:

PIG. 2 is` a view in front elevation ofthe press of PIG. 1';

FIG. 3 is a bottom plan wiew of the press;

FIG. 4 is a` detail, fragmentary plan view of' the` press headl with a door catch mounted thereon in operative position, looking in the dire'otion of the arrows of line 4 4` of FIG. l;

FIGSL 5 and 6 'are a side elevation an-dv` bottom plan view, respeotively, of an alternate form of press liead;

FiGSL 7 'and 8 are views in 'front and side elevation, respectively,.o-f still another 'form` of press head for use inV the press of the presentinvention; and

FIGS. 9 and IO are views in side eleVa-tion and bottom plan, respectively, of still another form of press head' for use in the presently described press.

In one of its forms the hand press of my. inven'tion comprises a press frame mounting a lever-operated toggle means, a press head and an anvil. First pivot means pivotally connect one side of the toggle tmeansv to the frame. Second pivot means 'pivotally connect the other side of the toggle means` to the press head. Guide means are provided for guiding the press` head in recipro'cating mo'vement.

The anvil is spaced yfrom the press head and aligned with its direction of reciprocating movement. In-` case the press is to be applied to the installation of a d'oor catch, the working sur-face of the press head is provided with a` post dimensioned to mount vthe catch) with the screws in place.

Adjusting means are associated with the anvil for spacing. the anvil a predetermined distance from the press head as required to accomm'odate a structunal' member of varying thickness. Also, adjustingimeans are asso'- ciated with the' anvil for locatingthe structural member laterally with respect to the catch, so that the catcl1"may be` applied in the correct location. k

As' a consequence, |merely by workingthe toggle With the levers, i-t is possible to press thescrews directly into thel -structural member in la single, rapidly eifectuated stroke, thereby m'ountingth'ecatohin theV desiredflocation'.

A novel 'and efficient method thu's is |providedfor attaching to structural'memibers spur-fiastened devices having a plurality of guide-ways and' a freely47 mova'ble'spur fastener extending through each guideway with`` its' head on'one'side' of the appliance and its spur on theother side. This method comprises inserting the fasteners in the guideways of one of the appliances; 'and-p-'ositioning the appliance' by keying together the appliance and` the press head, as by locating` the hcadsv o-f the tiastener'sfi correspondingirecesses'in the presshead.`` This;` in-turn, looates the aippliance in a predetermined position relative to the struotural`` member to which the applianceis tobe fastened; Thei'applianceiis held` in its pred'eterrnined` position while?` pressing the f'a'steners into the structural-` member, using the guideways, fiist;v tolretain the: fasteners and, secondly,` 'to guide-their? penetrating movement.

Considering the foregoing in` greater detailandwith particular reference to the drawings:

In its illustrated embodiment, the press is'mounted in a frame comprising :a pair of

plates

10, 12 arranged parallel to each other and releasably held together by screws 13. The plates are maintained in spaced relation by integral

lower bosses

14, 16 and integral upper bosses 18, 20.l Thus there are provided a lower opening 22 in which the anvil assembly is housed 'and an upper opening 24 in which the press driving assembly is housed.

The driving assembly broadly comprising lever-operlated toggle means, includes a first lever 26 provided at one end with a toggle-forming extension 28 which includes a pair of spaced integral plates 30.

A Companion lever 32 likewise is formed with a toggle-forming extension 34 and with a tongue 36 adapted to be received in pivoting relation between plates 30.

' The two levers are pivotally interconnected intermediate their ends by means of a pivot pin 38 penetrating the overlapped portions of plates and tongue 36.

The desired toggle action is provided by pivotally connecting the end of toggle-forming extension 28 between

frame members

10, 12 by means of a pivot pin 40. Also, the end of toggle-forming extension 34 is pivoted by means of pivot pin 42 to a press head 44. The two pivot pins are aligned With each other and with the work.

The press head may be of varying size and configuration as required by the pressing operation contemplated. It is provided with guide means for guiding it in reciprocal movement. In the illustrated form of the invention, the guide means comprise gibs 46 extending lengthwise along the side walls of press head 44, and corresponding gibways 48 cut into the inner side walls of

frame members

10, 12.

Where the press is to be used for applying catches on cabinets or other structural assemblies, means are provided for holding the catch and mounting screws on the press head. In the einbodiment of FIGS. 1-4, each catch 50 comprises a base to which are afiixed a pair of spaced

arms

52, 54. The arms are spring pressedby means of leaf spring 56. Screws 58 penetrate the catch for attaching it to a structural member.

When the press is to be used in attaching such a catch, the press head is provided with a mounting post 60 having a cross section slightly larger than the normal space between

arms

52, 54. The catch then is maintained on the post by frictional engagement.

Locating recesses 61 also are provided on the working surface of the press head. These are dimensioned to seat the heads of screws 58 and are arranged in a corresponding pattern, thus keying together the catch assembly and the press head. The recess pattern, of course, may be changed to accommodate catches having varying patterns of Screws by the simple expedient of providing interchangeable press heads.

The recesses serve the important function of locating the catch accurately with respect to the work, while the catch itself serves the important function of holding .the screws and aligning them properly.

Cooperating with press head 44 is an anvil assembly housed'in lower opening 22. The anvil assembly includes an anvil 62 which may be provided with a longitudinal slot 64. The inner side face of anvil 62 engages the side edges of

frame members

10, 12 in sliding engagement. An integral tongue 66 works in the space between

plates

10, 12.

Means are provided for adjusting the position of the anvil relative to the press head as required to accommodate work of varying thickness.

In its illustrated form, such means comprise screw 68, rotatably mounted in openings formed in boss pairs 14, 16 and 18, 20. The screw is maintained in position by a locating head 70 at one end and a knurled turning head 72 at the other end. The intermediate portion of the screw is threaded through tongue 66 of the anvil assembly. Accordingly, by turning knurled head 72, the position of anvil member 62 relative to the press head 44 may be adjusted as desired to accommodate the -shelf -or other work piece, indicated generally at 74.

Means also are associated with the anvil for locating the work properly With reference to the press head. This is desirable when installing door catches, since it makes possible mounting the catch the 'desired and predetermined distance inwardly from the edge of the work.

To this end there is provided a cover plate provided with an angled, upwardly extending abutment section 82 and guiding downwardly-turned fianges 84, one on each side.

Fixed to the underside of plate 80 is a rod 85, the outer end of which is threaded and provided with a knurled nut 86. Rod 85 works in longitudinal slot 64 through the anvil and may be locked releasably in any desired position of adjustment merely by tightening nut 86 against the under surface of the anvil.

In the alternate form of the invention illustrated in FIGS. 5 and 6, the press head is modified frictionally to hold a device or appliance indicated generally at 90 and comprising, for example, a door catch, hinge, or other similar member preferably provided with opposite side recess 91. The appliance is provided with a pair of guideways 92 in which are adapted to be inserted screws 94 `or other spur type fasteners arranged with the heads on one side of the appliance and the spurs extending through the other side thereof.

The press head 96 corresponds to press head 44 of the previously described embodiment. Its working surface is provided with a pattern of recesses 98 designed to accommodate the heads of Screws 94.

Frictional means are provided on press head 96 for releasably securing appliance 90 in its working position. Such means comprise an extension 100 on one side of the press head, cooperating with a leaf spring 101 fastened to the other side of the same. If desired, a second leaf spring 102 wedged into a slot 103 through the shoulder of the press head also may be employed. Appliance 90 then may be pressed between the two side pieces thus provided, with the heads of Screws 94 nesting in recesses 98.

The embodiment of FIGS. 7 and 8 is designed to aceommodate catches or other devices including magnetic elements. In this form of the invention, the magnetic element itself is used for releasably securing the device to the press head. As an example, the device may comprise a magnetic catch having a body 104 and a pair of oppositely disposed Shoulders 106. Guideways 108 extending through the latter are adapted to receive Screws 110.

Centrally of the body there are mounted a pair of wafertype floating magnets 112. These are suitably housed and, in use, are adapted to cooperate with a plate of magnetic material, not illustrated, in releasably closing a 'cabinet door.

The catch and plate are conventional and form no part of the present invention. However, the catch may be applied with the herein described press, modified by the inclusion of a press head 114 in the working face of which vare pockets 116 dimensioned to receive the heads of screws 110. The body 104 of the catch is received in an appropriately dimensioned recess in the working face of the press head. The recess is defined in part by outwardly extending stabilizing flanges 117.

A plate 118 of steel or other magnetic material is bolted or otherwise fastened to the side face of the press head. It is positioned in such a manner that when the magnetic catch is located in the press head with the heads of screws received in recesses 116, plate 118 on the press head will lie closely against magnets 112 in the catch, holding the catch securely, but releasably, in position.

Still another form of the invention is illustrated in FIGS. 9 and 10. This form is adapted for use with catches such as the above mentioned Jorgensen catch, illustrated in sperma-e 51' -IG. 412-4; Howver, an altern'a'te mode of` holding the 'catch on theu press head' is featured.

Accordingly, in this form of the invention, the press head3 1'20 is provided withirecesses 122'` to locate the screw heads, and also With a downwardly-extending wedgeshaped`post'12`4; Thelatter serves a`` function analogous to that served by mounting post 60; previouslyl described in that it enters between the javvs` of the catch, but from the side, with the ends of the jaws received; in oppositely placed pockets 126'011 the' side faces of the post.` This manneriof mounting the catch on the press' head* maybe acomplished more easily inA some situations.

Operation The` operation of 'the herein described hand press, as'

cabinet` shelf 74v or other structural member: inV a proper``` workingI position.

Next, the locating platevlllis positioned longitudinally of anvil member 62- by moving rod 85'unti1the upturned abutmentfmember 82 is located properl'y. Plate 8'0 then is locked on place by'tightening down on knurled nut 86.

Next, the screws are inserted in the catch andthe resultingassembly. slipped: over post 60on the press head in the manner shown particularly in FIG. 4. As this is done, the screw heads se'atin recesses 61 of the press head surface (FIG. 1'), thus-keying-- together the catch and press head, and l'ocating the catch properly with the screws aligned and restrained' from falling out. Still further, the catch itself is held in place by the frictional` engagement of the catch arms againsttthe side walls of the post.

Thework 74 is` placed' on the anvil and pressed' snugly against abutment 82.

Levers

26, 32 then are brought together by hand pressure. This drives the press head through atstroke measuredjby the stroke arrows of FIG. 1. In so doing, it drives screws 58 into the wood in an operation made both easy and' accurate by the fact that all' of the elementsof the assembly are properly located and aligned, as well as by the fact that the lever handles move independently of the frame. This floating arrangement prevents-pressure appliedito theV handles from canting the press headso that-,the screwswould ;be improperly inserted.

Also, the applied' pressure resulting from the lever ad- Vantage, coupled with the advantagey obtained by opening the toggle formed by

togglev extensions

28, 34, is enormous and more than ample to drive screws- 58 completely into the work in a single easy stroke..

After insertion of the screws, the levers maybe moved from the closed position of FIG. 1 to anopen position. This action strips the latchfrom` porstfilt)` and leaves the tooltready for use in installinganother catch.

The application of the inventionto the form of p the invention illustrated' in FIGS, 5 and 6 is similar. However, in this instance the door catch or other appliance 90 is merely slipped-.between side ;plates-100, 102-` of the press head 96, the resilient pressure exerted by spring plate 102 serving to anchor the appliance in place as it is installed.

In the embodiment of FIGS. 7 and 8, the mode of operation again is similar. In this case, however, a magnetic appliance or device 104 is seated in a press head 114, the attraction between magnets 112 in the device and side plate 118 on the press head serving to secure the device to the head as it is driven into the work.

In the form of the invention illustrated in FIGS. 9 and 10, a catch having a construction similar to that illustrated in FIGS. 1 and 4 is mounted on a press head 120 equipped with a wedge-shaped side mounting post 124. The catch merely is slipped over the post with the arms seating in recesses 126 thereof, using a longitudinal motion of the catch rather than a` sidewaysflmotion, a's` was the case in the embodirnent of FIGS. 1)-4L It is to be observed particular-ly that?` allJ ofthe above described forms ofZ the invention arefl'characterizedv`` by illustrating a novel. method of attaching to structural' members spur fastened appliances having a plurality of'guideways therethrough in which' the' spur fasteners freely extend, with their headson one side of theapplianceandthe spurs on the other.

The method comprises firstl inserting the fasteners in the guideways. Next` the appliance i`s`- located accurately with respect to the work by positioningithe1 headjs of the fasteners` in the recesses or pock'etsprovided` in= a corresponding pattern' inA the working'face'of the= press head. The appliance then is held two dimensionally in itspredetermined position relative tothe structuralmember to which'it` is being-attachedwhile thefasteners are prcssed into it. During this operation, the guidewaysareJ employed to hold the spur members in` their proper position relativeto the work and at' the same timeito guide their penetrating movement. Eccentric leading, and consequent bending, of the screws thusisl prevented As a result, with a single, easily-effectuated` stroke of the press, the appliance istfastened to the worl'r` iniexactly i the proper position with the spburV members corr'ectly aligned.

ft is to be understood that the forms'iof my invention herein shown and` described'-` areV to-be` taken aspreferred1` examples of the same and-` that variousto'ther` changes in` the shape, size and arrangement of parts may be-resorted to without departing from the spirit. of my` invention or the scope ofthe subjoined claims;
