A spring acts on the lever so that cured to the base-portion opposite the jaws of normally the pintle is yieldably held within the 30 the slidable bolt. socket. At the opposite rear bottom corner of The bolt engages preferably the front pair of the case, another pintle and a socket are provided, typewriter-feet, and co-operating therewith, to and these may be fixed, that is to say, neither one form three-point attaching means, there may be is movable with respect to the base or cover poran anchor-piece located centrally at the rear bottion to which it is attached. 35 tom margin of the typewriter-iframe, and e By swinging the pintle-lever, its pintle is withgaged by suitable means attached to the basedrawn from the socket, and that corner of the p cover-portion may be slightly raised, whereupon In one form of the invention illustrated herein, the base and co e por ma be separated at 49 the stationary jaws are provided, and these, with the opposite corners to disengage the fixed pintle the bolt-jaws, when the bolt is home, form rings and socket. The pintle-carrying lever may have encircling and overtopping the foot-fianges, and an arm extending along the edge of the baseboard thereby, in co-operation with the secured rear in such manner that when the cover-portion is anchor-piece of the typewriter-frame, retain the in p a t Side Of e V SeI'VeS as a p 5 typewriter on the base-portion. to prevent rotation of the pintle-lever, and thus In another form of the invention illustrated locks the lever-carried pintle within its socket. herein, the stationary jaws are omitted, the jaws n a S milar a the COVE?, When in Place on the bolt, half encompassing and overtopping over the base-portion, may also serve as a lock the foot-fianges, being suffcient to hold the typefor the slidable clamp or bolt which simultanewriter down upon the base-portion. In this arously engages both front feet of the typewriter, 50 rangement, in order to secure the typewriter said clamp or bolt being provided with an extenagainst sidewise displacement, sockets fitting the sion which just abuts the inner side of the cover feet of the typewriter are sunk into the base-porwhen the bolt is moved home. Unless the bolt is tion just deep enough so that the edges of the moved home, said extension will overlap the side 5 sockets may prevent said sidewise displacemeht` edge of the base-portion and prevent the closng of the cover-portion thereover. It is thus assured that when the cover is closed over the base-portion, the typewriter within cannot become loosened from the base-portion.

In a certain other style of case, the sides of the base-portion are upturned to form a shallow rim. For this style of case, the present improvements provide a hinge formed of two leaves, one leaf carrying a pintle, and the other leaf being curled to form a knuckle for said pintle. The pintlecarrying leaf is also formed with a rest upon which the pintle-receiving knuckle of the other leaf may rest while said knuckle is being slid over the pintle. The pintle-receiving knuckle may have a transverse hole in which may be retained a spring-pressed detent-plunger co-operating with a groove in the pintle for yieldably holding the cover and base portion in hinged relation, it being understood that, axially of the pair of spaced pintles, the cover and base portion may be shifted relatively to one another to either separate them or bring them together again.

It will also be understood that preparatory to so bringing them together again, the pintle-receiving knuckles of the hinges may rest upon and be guided by the aforesaid rests formed on the pintle.

For use with the style of the case in which the edges of the base are upturned, the present improvements afford means for locking the bolt in position to hold down the typewriter-feet, said looking means being constructed to also serve for Conveniently shifting the clamp-bolt.

Means are also provided for retaining a supply of stationery within the case.

The clamping means and hinging devices are so arranged as not to impair the use of the case for general purposes, the clamping means being arranged close to the top of the base so as to take up a minimum of room and also so that there are no loose parts subject to loss or injury when the typewriter is removed. The same is also true of the pintle-lever.

Other features and advantages will hereinafter appear.

Figure 10 is a detail view of one of the leafhinges.

Figures 1, 2, 3 and 5 represent a carrying case in which a rectangular fiat board forms a base !5, on which is to be detachably supported a typewriter !6. A deep cover H has its sides telescopically fitting over the side edges of said base !5. Fastened to the inner vertical corners of said cover i'l are. quartered pieces l8, against the outer ends of which the inner surface of the base l5 abuts, to position said base fiush with the outer rim of the cover.

Fastened to the bottom of the typewriter [6 are the usual four cushioning feet, one pair of feet I!) being toward the rear, and the other feet being toward the front of the typewriter. The top of the base [5 has depressions 2l (Figure 2), into which the feet 19, 20 are seated for locating the typewriter and retaining it against shifting around on said base. From the rear bottom margin of the typewriter, and centrally thereof, there projects a hook or tongue 22, which, as set forth in my pending application, 570300, filed October 22, 1931 (now Patent No. 1,880,891, dated October 4, 1932), serves to hold the rear end of the typewriter against the baseboard 15, the latter being provided with a strap 23 forming an eye in which the tongue 22 is entered as the typewriter is set upon the base !5.

For holding down the front of the typewriter, the present improvements provide an elongate clamp-bolt 25 for engaging shoulders 26 of the front feet 20. The bolt 25 is slidably guided and retained on the base l5 by means of headed screws 21, having shanks driven into the base 15 and slidably fitting elongate holes 28 of the bolt 25. A strap 29 may overlie one end of the bolt 25, and is fastened to the base I5, said strap cooperating with the head of one of said screws 21 in holding said end of the bolt against the baseboard.

The bolt 25 may be formed so that the greater portion thereof lengthwise lies upon the base I5. The bolt may be formed of sheet-metal, and, for overtopping the shoulders 26 of the front feet 20, it may have struck up therefrom portions forming jaws 30 spaced from the base !5 sufilciently so that said jaws may overtop said shoulders 25. Semi-circular openings or notches 3| of. the jaws are constricted continuations of perforations 32 formed in the bolt-portions lying next to the base !5, said perforations being large enough to admit the bottoms of the front feet 20 in position to be engaged by the jaws 30 when the bolt is slid home.

From Figure 5, it will be seen that the bolt 25 spans both front feet 20 of. the typewriter, and it will be seen that a single Shift of the bolt either brings it into position to lock both feet to the baseboard, as indicated in Figure 5, or into position to clear both feet, so that the typewriter may be withdrawn from the base, as is evident from Figur-e 2.

That end of the bolt which moves inwardly when the bolt is shifted home is arranged to be ush or slightly within the side edge of the base |5 when the bolt has been so shiited. Thus, when the cover il is closed over the base [5, the side 33 of the cover serves to lock the bolt in its home position, as seen in Figure 5. said end of the bolt which thus is obstructed by the side 33 of the cover may also have a turned-up fingerpiece 24, whereby the bolt may be manipulated for shifting it to either one of its positions. Inasmuch as the cover l1 when closed down upon the base l prevents the bolt 25 from being shifted out of looking engagement with the front typewriter-feet 20, the possibility of the typewriter becoming loosened from the base !5 while said typewriter is being carried around within the case is precluded. It is also assured that the typewriter is properly clamped down upon the base !5 when the cover i1 is closed over said base, because, if the typewriter is not so clamped down, it will be because the bolt 25 has not been shifted home, and hence the end of the bolt carrying the finger-piece 24 will project beyond the side of the base and will bar closing of the cover thereover. Secured to the tops of the shoulders 26 of the typewriter-feet 20, there may be metal washers 35 to guard said shoulders against wear by the clamp-bolt 25. The front feet 20 depend from lugs !2 of the typewriter-framework and may be secured by suitable means as, for example, a headed screw |3 passing through the lug Z and foot 26 and threaded into a nut (not shown) molded or sunk into the bottom of the foot. A Washer |4 may underlie the head of the screw l3, the top of the foot having a reduced portion H entered into the lug !2. The feet !9 are similarly fastened.

For detachably hinging the cover |1 to the base !5 in such a way that the case may be opened without the cover and base becomng immediately sparated, the following hinge-devices are provided. Into the sides of the bottom rear corners of the cover, there are fastened plates 36, having elongate holes 31 forming sockets for receiving hinge pintles. The elongation of said holes 31 permits the base !5 to move forward slightly as the case is opened. By this slight forward movement the rear edge of the base |5 clears the cover l1. One of said pintles, namely, the pintle 38, is rigidly fastened to one of the rear corners of the base !5, said pintle 38 projecting laterally from an angle-piece 39 which may be fitted into said corner of the base, as indicated in Figures 2 and 3, and may be Secured by rivets 46. A pintle 4| at the opposite rear corner of the base |5 is mounted so that it may be withdrawn from its socket 31 in order that the cover I 1 and the base !5 may be separated. For so mounting said pintle 4l, there is a lever 42, having arms 43 and 44 extending from opposite sides of a fianged collar 46 (Figura 1), whose fiange 45 is sunk into the base !5, so that the fulcrum forming collar 46, topping said flange, projects above said base to receive the lever 42. A headed screw 41 passes through said collar and is threaded into a nut 48, which may be driven into the under side of the base !5, said screw 41 and nut 48 serving to clamp the collar 46 down upon the base !5, and the screw-head servng to hold the lever 42 in place. The rearwardly-extending arm 43 has a downwardly-bent portion 49 from which the pintle 4! may project, For clearing said downwardly-bent portion 49 of the arm 43, the corner of the base may have a jog 50, Figure 3. said portion 49 of the lever 42 does not extend to the bottom of the base, and a plate 5! may therefore be sunk into said bottom of the base to form a closure for said jog 56. For yieldabiy holding the lever 42 in the position in which the pintle 4! is within its socket 31, there presses upon the arm 43 of said lever a spring 52. To afford room for said spring 52, the side of the jog 50 may have a hole 53 forming a socket, against the bottom of which one end of said spring may react. The other end of the spring reacts against a head 54, which may be part of the pintle 4l. A pin 55, driven into the base 5, serves as a stop to limit the rotation of the pintle-lever 42, that is to say, with the arm 44 of said lever abutting said sto-p, a finger-piece 56, formed on the end of said arm, Will be just within the side edge of the base !15, and the pintle 41 will be in the position in which it is when received within the socket 31. It will be evident that with the cover |1 closed down upon the base l5, the pintle 4! cannot withdraw from its socket 31, because the side 33 of said cover prevents rotation of the lever 42. Figure 3 indicates how the cover I1 and base !5 may be separated or brought together again when the lever 42 is swung to retract the pintle 4! within the jog 50 of the base.

The present improvements provide simple means for storing within the case a supply of stationery. Fastened centrally to the rear side 58 of the cover, and spaced from the top 59, is an angle-piece forming a ledge 60, which with said top 59 of the cover forms a rack, into which may be received and held one side-end of a stack of stationery. A swingable bail 63 is pivo-ted between 'brackets 64, fastened to the front side 65 of the cover. The pintles of the bail which are received by the b-racket 64 have turned ends 66, against which may react one end of springs 61 which may be curled around said pintles, the other ends of said springs each reacting against the portion of the bracket 64 that is fastened to the front cover-side 65. The springs 61 cause the bail 63 to press toward the top of the cover 59, and hence the stack of stationery is held against said cover by said bail and may 'be withdrawn when the bail 63 is swung away.

The inner side of the cover-top 59 may have the usual plate 69, against which the swiveled linespace handle abuts when the cover is closed over the typewriter. At the front side of the cover, there are provided the usual carrying handle 1l and a portion 12 of the usual lock, said lock having a complementary portion 13 at the front edge of the base |5. It will be seen that the clamping and hinging organization is such as not to interfere with the use of the case for other purposes than that of carrying a typewriter. The clamp-bolt 25 is substantially fiat and offers no obstruction. It constitutes a single piece serving to hold down both front feet of the typewriter and is easily manipulated, to the end that the typewriter may be quickly withdrawn from the base or may be quickly and securely replaced upon the base. When using the carrying case as an overnight bag, for example, the base |5 becomes a top lid, which may be opened and closed without detachment from the coverportion I1. For facilitating manipulation of the lid to open it from the bottom-portion I 1, it may be provided with a lip ?4, which may be made accessible by relieving the edge of the front side 65 of the cover, as at 15.

Figures 7, 8 and 9 illustrate another organization for clamping and locating the typewriter l6 to a base 16. In this organization, there is also used an elongate d'uplex clamp-bolt 11 for simultaneously engaging both front feet 20 of the typewriter. The foot-receiving dcpressions in the base shown in Figure 2, and which serve to locate and hold the typewriter against moving around on the base, are omtted, the base 16 to which said other organization is applied not having said depressions. In lieu thereof, there are provided fixed jaws 18, 19, each having a notch 88 formed to half encompass the neck which tops the shoulder 25 of the typewriter-foot 29. The encompassing of said neck is completed by a notch 8| in a jaw 82 of the clamp-bolt T'i, said clamp-bolt having two of said jaws 82, one for each foot 20 of the typewriter. The fixed jaws 18, 19 together with the jaws 92 of the movable bolt 11, when encompassing the necks of the typewriter-feet 20, serve to locate the typewriter and confine it against moving around on the base when said bolt is shifted home.

The fixed jaws '18, 19 are formed of straps 83 fastened to the base 16 and having upward ofisets 84 to bridge said jaws 18, ?9 over the boltportions 85, said bolt-portions 85 having perfol'ations 88 of suitable form, as indicated, to admit the typewriter-feet 20 when the bolt is open. The ofisets 84 of the straps 83 fit the sides of said bolt-portions 85 and thns serve to slidably guide the bolt 'H on the base ?6. said bolt 'H is made of sheet-metal and the portions forming the jaws 82 thereof are struck from the central portion of the bolt which lies against the base, so as to overtop the shoulders 28 of the typewriter-feet 28. Referring to Figures 7 and 9, the portion 85 may, as will be seen at the left end-portion of the bolt, be offset downwardly, as at S'i, to pass under and abut the fixed jaw 18, it being noted that the portions of the fixed jaws ?8, 19 and of the movable jaws 82 which embrace the feet 28 are preferably on the same level. The offset at 81 may not bring the bolt-portion 85 to lie against the base and there may be formed near the end 88 of said bolt another ofiset which brings said end down to lie upon the base. An alternative way of bringing the fixed and movable jaws to the same level is seen at the right end-portion of the bolt in which the portion 85 and the jaw 82 are not .ofiset from one another. Instead of such o-ffset, the portion of the fixed jaw 19 around the notch 80 of said jaw is depressed to the level of the movable jaw 82, the diameter at the under side of the depressed jaw-portion being within the sides of the perforations 88.

In carrying out a certain design for the case, the base 18 may be formed with upturned edges 98. Therefore the extent `oi' 'the outwardlymoved end of the clamp-bolt must be limited, so that when said bolt is shifted, said end does not interfere with said upturned edges 98 of the base. For shifting or looking the bolt under these conditions, there is provided a plate 9! slidably retained in a guide 92 i'astenecl to the base '18. For slidably guiding the plate 91, said guide 92 has at one end an upturned edge 93 and a similar opposite edge that is turned over the plate as seen at the portion 94 of said guide. The other end of the guide 92 has a similar turned-up and over portion 95, said portion 95 co-operating with the side of the strap 83 to guide the plate 9l laterally. It will be noted that in order to so guide the plate 9l, the strap 83 at the right is widened to the extent of portions 83 of said strap. The movement of the plate 9l transversely of the bolt 11 is translated into boltshifting movement by means of an inclined camslot 98 in said plate, said cam-slot engaging a pin 91 projecting downwardly from the end of the clamp-bolt. The plate 9l, held down along one side thereof by the turned-over portions 94, 95 of the guide, is also held down on its opposite side by the end of the bolt, said end of the bolt being therefore offset downwardly, being bent at 98 to abut the top of the plate 9 i. For manipulating the plate 9L to Shift the bolt, it may have an upturned finger-piece 99.

The inclined cam-slot 96 has a portion no which is perpendicular to the clamp-bolt. Thus, When the plate 9| has been moved forwardly to move the clamp-bolt home, said portion !08 engages the bolt-pin 91 and, being square with the direction of bolt-movement, looks the bolt in its home position. The plate 9l may, itself, be locked when it has been moved to shift the bolt home, the locking of the plate being efiected by means of a latch-lever !02 pivoted to the plate on a headed stud !03. said latch-lever !02 has an arm !84 notched at its end to engage a corner of the turned-over portion 94 of the guide 92, the lever being arranged on the plate, as seen in Figure 8. An upturned finger-piece !85 of the latch-lever is disposed alongside of the finger-piece 99 of the plate 9l, so that preparatory to releasing and shifting said plate, both the finger-pieces 99 and I may be grasped simultaneously. The closed end of the cam-slot portion !00 may be positioned to limit the forward movement of the plate 91, by abutment with the pin 91, so that the tips of the latcharm cannot get wholly behind the corner of the guide-portion 94 which said arm engages. It will be understood that the plate 9l may be drawn forwardly far enough so that the end of the latch-arm !04, when the arm is being withdrawn, may be swung clear of said corner preparatory to shifting the plate rearward. A spring !01 coiled around a stud !88 presses upon the iatch-arm !04, so that said arm may automatically snap into looking relation with the corner of the guide-portion 94 when the plate 9l has been moved forwardly. Figure '7 shows the plate SI moved rearwardly in consequence of which the bolt 11 has been moved to the right to separate the clamping jaws for removal of the typewriter or for replacement thereof upon the base 16.

With the organization seen in Figures "I and 9,

there are also used an anchor-hook 22 at the rear of the typewriter and an eye-piece 23 fastened to the base 16. With the j aws of the clamps open, and the typewriter IE turned by swinging it about the eye-piece 23, as indicated by the skewed broken Outline representing said typewriter !6, Figure 7, the front feet 28 may either be admitted to the perforations 86 of the clampbolt 11 or they may be withdrawn from said perforations. It will be evident that when the typewriter is shifted from said skewed position to its normal position shown by another broken Outline, the necks of the front feet will then be brought within the notches 80 of the fixed jaws 18, 19. When the typewriter is in its normal position, the bolt is moved to the left by shifting the plate 9l forwardly whereupon the bolt Will also be locked by said plate as already explained, the parts being then in the position seen in Figure 9, to securely hold the typewriter to the base 16.

Hinges arranged for application to the carrying case having a base with upturned edges are seen in Figures 6, '7, 9 and 10. Each hinge includes a pair of leaves llfl, III. The leaves HO are fastened to the rear side of the upturned edge 90 of the base 16, each leaf HO having at one end a socket 3 in which is fastened a pintle IM Said pintle projects far enough from said socket to enter the full length of a knuckle |l5 formed on each of the pair of leaves lil which are fastened to the rear wall of the top cover I I T. Each pintle carrying leaf n includes a rest ||8 disposed beyond the end of the pintle. The hinge-knuckles I forming part of the cover H'I are laid against the rests 8, to guide them over' the pintles. 4, thus conducing to the celerity with which the cover and base may be brought together in hinged relation. Each rest l I 8 may have a groove I !9 into which the knuckle ll5 may be set to facilitate the guiding of the knuckle onto the pintle. A detent-device may be applied to one of the hinges to prevent unintended relative lateral displacement of the cover and base after they have been brought together. said device is preferably yielclable so that, while ordinarily preventing such displacement, the cover may, when desired, be separated from the base by overcoming said d'etent-device. To this end, the knuckle |l5 may have a transverse stern IZO which may be drilled to receive a detent plunger or ball l2l, a spring !22 pressing upon said ball and being backed by a screw 123 threaded into the end of the stern. When the cover and base are assembled in hinged relation, the spring !22 presses the ball IZI into the groove 124 on the pintle and thus the cover and base are yieldably held together.

The hinged leaves. o, lll may be sunk, as indicated at |25, Figure 6, into case-portions to which they are fastened by rivets ZB. The bottom edge of the cover ll'l may have a projection 121 which, fitting within the upturned edges 90 of the base, prevents relative lateral displacement of the cover and the base when said cover is closed upon the base.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.

6. The combination with a baseboard, for suppo rting a typewriter having a pair of feet resting on said baseboard, of a clamp-bolt slidably mounted on said baseboard, so as to be shiftable between two positions, one position for engaging said feet and the other position for being free of said feet, and a slide mounted on said baseboard for movement transversely of said clamp-bolt, said clamp-bolt and slide having cooperating camming devices whereby movement of said slide in one direction shifts said clampbolt to one position to engage said feet, and whereby movement of said slide in the opposite direction shifts said clamp-bolt to the other position to free said feet.

7. The combination with a baseboard, for supporting a typewriter having a pair of feet resting on said baseboard, of a clamp-bolt sliclably mounted on said baseboard, so as to' be shiftable between two positions, one position for engaging said feet and the other position for being free of said feet, and a slide mounted on said baseboard for movement transversely of said clampbolt, said clamp-bolt and slide having co-operating cammng devices whereby movement of said slide in one direction shifts said clamp-bolt to one position to engage said feet, and whereby movement of said slide in the opposite direction shifts said clamp-bolt to the other position to free said feet, said camming devices being arranged to lock the clamp-bolt in its feet-engaging position against movement independently of said slide.

8. The combination with a baseboard, for supporting a typewriter having a pair of feet resting on said baseboard, of a. clamp-bolt sli'dably mounted on said baseboard, so as to be shiftable between two positions, one position for engaging said feet and the other position for being free of said feet, a slide mounted on said baseboard for movement transversely of said clampbolt, said clamp -bolt and slide having co-operating camming devices whereby movement of said slide in one direction shifts said clamp-bolt to one position to engage said feet, and whereby movement of said slide in the opposite direction shifts said clamp-bolt to the other position to free said feet, and a releasable spring-pressed latch to lock said slide when it has been moved to Shift the bolt to its feet-engaging position.

9. For use with a typewriter having apar of cushion feet having shouldered exteriors, a baseboard, a pair of jaws fixed to said. baseboard and arranged thereon to engage said feet at similar sides and formed with portions to half encompass and overtop the shoulders thereof, and a duplex clamp-bolt slidably mounted on said baseboard, said clamp-bolt spanning said feet and having jaw-portions at its ends arranged to overtop said shoulders on the sides of the feet opposite to the sides engaged by said fixed jaws when the bolt is shifted. in one direction, and to withdraw from said feet when the bolt is shifted in the opposite direction for opening the jaws and removing the typewriter from the baseboard.

10. A portable typewriter-hold-down device associated with a carrying-case baseboard on which a pair of spaced feet of the typewriter rest, each foot having a base which rests on said baseboard, a hold-down shoulder, and a neck above the shoulder, said hold-down device including a single retractible clamp-element spanning said feet, said clamp-element comp rising a bar on the baseboard, said bar having portions above said baseboard to engage said feet, the bar being held down on said baseboard, for Shift between clamping and retracted positions, apertures being provided in the bar for admitting said feet to contact with the baseboard when the clamp-element is in retracted position, said apertures being formed so that said portions clutch the necks of the feet, and overlap the foot-shonlders to 'hold the feet down on the baseboard, when the clamp is shifted to effective position, the baseboard and hold-down device co-operating to lock the typewriter against both lateral and vertical displacement relative to the baseboard during transportation, and a cover by which the clamp-element is locked in effective position. p

11. For use with a typewriter having a pair of cushion feet, each formed with a shoulder, a baseboard, a pair of jaws, one for each foot, said jaws fastened to said baseboard to clasp over the shoulders of the feet, each jaw being fixed at the same side of its own foot as the other jaw, so that movement of the typing machine in one direction may release both feet from their fixed jaws, and clamping jaws connected together and mounted upon said baseboard for movement in a single direction, to close 'as a unit against said fixed jaws.
