State of Massachusetts, have invented cer-. tain new and useful'Im rovements in Type-- Writing Machines, of w 'ich the following is a s ecification.
his invention relates to detachable cardholders for the cylindrical platens of type writin machines. I
Eac holder, of the type to which this invention belongs, comprises a metal strip extending the length of the platen. and having any suitable card-holding means such as a series of teeth to engage the edges of the card and at its ends, the strip is bent. down to form claws, having hooksto catch over the metal heads of the platen. In practice, it is found desirable to form these claws so that they will have a strong grip, and conse uently, it is found awkward to'release them.
he object of my invention is' to provide simthat the card-holders may be readily detached from the platen.
. ried upona platen axle 4; and typ In the accompanying a front elevation of my improved car -holder showin the same in positlon upon the cylindrical p aten of a typewriti machine. Fi
2 is an end view of the p aten and car holder. Fig. 3 shows the left hand end portion of Fig.- 1, and illustrates the manner-of releasing one end of the card-holder.
Fig; 4 is similar to Fig. 3, but showsthe end of the card-holder released, and. being withdrawn fromv the platen. Fig. 5 is a perspective view of the cardholder detached from theplaten.
The cylindrical platen 1 of a writing ma-flchine is usually provided with disk-like metal heads 2 the latter having integral hubs 3 car-- es 5 usu-' ally strike against the front of the platen, as for instance in the well known Underwood machine.
The card-hbllder may be of any suitable t c. ti'lilcd as comprising a metal strip 6 having tooth 7 projec ing therefrom, to receive the edge of a card The strip 6 and the teeth 7 lie quite close to the platen, so as to pass easily the usual pressure rolls 9, 10. At each (end, the metal of the strip 6 is bent down to for-ma claw 11, whichis recessed at 12, to
drawings, Fi ure 1 is In the present instance," 1t is-illus form forks 1'3, to go over the hub 3, which is formed with flat sides, as seen at 14, to fit in the recess 12 and prevent the card-holder from slipping around relatively to the platen. At their tips, -the forks 13 are formed with hooks 15 to catch over the edges of the heads" 2, thus .avoiding liability of accidental detachment of the cardholder from the'platen, the claws 1 1 being'sufficiently s ringy .to give.
the hooks 15 a good hold for t is purpose.
To release the hooks; 15, I rovide the claws with wings 16, which are ormed with forks 17, to correspond with the forks 13', and are secured thereto by means of rivets 1 8, near thetips of the claws. At their upper or free ends, these wings are considerably set oil from the claws, as seen at Fig. 1, to form finger-pieces, movable towards each other to release the claws, said finger-pieces occup ing positions upon the same side of the huhs as; e strip 6,- or between said strip and the In order to release the card-holder, the wings 16 may be pressed towards each, other, thereby flexmg t eclaws 11 or the forks 13 sufliciently towithdraw the hooks 15 from the heads 2 as seen in Fi 3, whereupon the card-holder may be rea ily taken off from as atFig. 4, the releasing of this end' permitting the claw at the other end of the cardholder to become disengaged readily from the head 2.. Variations may be resorted to within the scope of the invention, and portions of }the implrovements may be used without others. aving thus described my invention, 1 claim:
1. A detachable card-holder for use upon the cylindrical platen of a t pewriting machine, comprising a card-.hol ing strip to extend the len th'of the platen, springy claws In some cases, one of the releasing deu on the en s of the strip to extend past the p aten axle and hooked at their ti s to catch over the heads of the platen, an wings secured at their lower ends to said claws near the tips of the latter; said win s having their upper ends set off from said 0 aws to permit said-upper endsto-be forced towards each,
other to spring the tipsof the claws away from said heads.
2. A detachable card-holder-for use upon the cylindrical platen of a typewriting machine, comprising a card-holding strip to extend the length of the platen, springy claws upon the ends of the strip and having hooks to catch'upon the exteriors of the platen heads, and finger-pieces upon said claws and movable towards each other to release said hooks from the platen heads.
3. A detachable card-holder for useupon" thecylindrical platen of a typewriting ina- I chine comprising a card-holding strip to ex tend the length of the platen, springy claws upon the ends of the strip and having hooks to catch upon the exteriors. of the platen heads, and finger-pieces upon. said claws and 'movable' towards each other to spring the claws awayfrom the heads of the platen to t release said hooks from said heads.
4. A detachable card-holder for use upon the cylindrical platen of a typewriting ma-' chine, comprising a cardholding strip to extend the length of the platen, a springy claw upon one end of the strip having-means to.
catch upon-the exterior of the platen head, a finger-piece. in the form ofawing extending from said claw and movable towards the platen head to flex the claw to release said catching means, and means upon the other end of said strip to catch upon the exterior of the other platen head.
5. A detachable cardholder for useuponthe cylindrical platenoita typewriting Ina-- chine, comprising a card-holding strip to ex tend the length of the laten, aspringy claw forked to pass beyond the platen hub and provided with hooks upon its tips to catch over the exterior of the platen head, a releasing finger-piece in the form of a wing havingforks securedto the forks of the claw, the free end of said wing set ofi from the'body of 'the claw, and means upon the'other en dof the stri to catch upon the exterior of the other p aten head.
tend the length of the platen, and devices cure the same upon the exteriors of the heads having'the form' of a springy claw forked to pass beyond. the platen hub and provided platen head, and each claw provided with a releasing finger-piece'in' the form of a wing the free end of each wing set offfrorn the body of'theclaw. 7. A detachable card-holder for use-upon the cylindrical platen of a .typewriting machine, comprising a card-holder strip to exing fingerepieces'upon' the ends of said card holder to occupy positions between the cardrelease-the catching'means.
8. A detachable card-holder foruse'upon the cylindricalplaten-of a typewriting Inatend the length of the platen and'provided at teriors ofthe heads of the platen, and releasing finger-pieces connected to the claws and 6. A detachable card-holder for use upon the cylindrical platen of a 'typewriting m'achine, comprising a card holding strip to extend the length of the platen and provided at its ends with means to catch-upon the eX- teriors of the heads of the platen, and releas-- holding strip andthe -hubs of the platen, saidfinger-pieces movable towards each other to chine, comprising a card-holding strip to ex z.
mounted to occupy positions betweenfthe ends of the strip and the platen hubs, and
extending from the ends of the strip to se-.
of the platen, each of said securing devices 1' with hooks upon its tips to catch over'the having forks secured to the forks of the claw,.
