PAPER-CLAMP FOR TYPE-WRITING MACHl NES.

SPECIFICATION forming part of Letters Patent No. 747,916, dated December 22, 1903. Application filed March 7, 1902. Serial No. 97,041. (No model.)

To all whom it may concern:

Be it known that I, FREDERIO W. HILLARD,

a citizen of the United States of America, and

a resident of Tottenville, borough of Richmond, city and State of New York, have invented certain newand useful Improvements in Paper-Olamps for Type-Writing Machines, of which the following is a specification.

The present invention relates to paper- IO clamps for type-writing machines of that class known as book type-writing machines such, for instance, asmade by the Elliott & Hatch Book Typewriter Oompanyin which the paper to be printed upon is retained on a [5 flat platen.

It is very desirable in machines of the described class'not only to provide means for retaining the leaf of the book to be printed on in smooth condition toireceive the impact of the printing-type, but also to retain a separate or loose sheet-letter, legal-cap, or the like in position upon the platen.

The main purpose of the present invention is, therefore, to provide means for holding loose sheets from one end against displacement, as by line-spacing the carriage and carriage-frame,withou t requiring the insertion of the sheet under the base-frame for holding it. Another and. an important object of the for type writing machines which may be readily adjusted and set in adjusted position relatively to the platen,particularly relatively to the length of the platen and of the sheet. or leaf, and to provide means whereby the carriage of the type-writing machine may be utilized to automatically release the clamp from the sheet or leaf when the said carriage has reached the limit of its return movement. A further object is to provide means for both automatically clamping and automatically releasing a sheet or leaf and to adapt the clamp for properly securing a sheet or leaf of any size less than the-area of the opening in the base-frame of the machine which is ordinarily employed in book type-writing machines to bind the edges of the sheet or leaf against the platen.

A further object of the invention is to conzo present invention is to providea paper-clampresting upon the platen also.

struct atype-writing machine so as to receive tain features of construction and combinations of parts to behereinafter fully described, and. then claimed.

In the accompanying five sheets of drawings, which show the invention applied to .the machine covered by my copending appli- 6o cation, Serial No. 86,999,-filed December 23, 1901, Figure 1 is a perspective view showing a table, a platen, and a base-frame resting on the table, in which view my improved paperclamp is shown in use, the machine proper, however, being omitted, so as to permit a clearer view of the clamp in its position upon the base-frame. Fig. 2 is a plan view of the clamp and portions of the base-frame to which it is attached and the platen, the clamp-locks or keepers being shown in full lines in position for holding the clamp inoperative and being shown in dotted lines as released from the clamp while the latter is in position of use. Fig. 3 isa side view of the same parts, the clamp being shown in raised position in full linesand in using position in dotted lines. Fig. 4 is a perspective View of the clamp detached from the machine. Fig. 5 is a rear elevation of the platen, base-frame, and pa- 8o per-clamp. Fig. 6 is a sectional detail view showing the means for fixing the clamp in position, taken on section-line y y of Fig. 2. Fig. 7 is a sectional side view showing parts of the machine covered by my aforesaid applic-ation with'the clamp applied, the object of this view being to show that when the carriage is in writing position and the movable scale and pointer are lowered upon the platen the clamp, if released, is. in using position, 0

Fig. 8 is a similar view, most of the carriage being broken away, the carriage having been moved to the first raised position for permitting an eXamination of the work,inwhich position the scale, 9 5 pointer, and paper-clamp still rest upon the platen; and Fig. 9 is a similar view in which the carriage has been moved to second raised i t i position, thereby raising the scale and pointer and at the same time automatically raising the clamp from the sheet.

A table 1 is shown in Fig. 1, which supports a platen 2 and a base-frame 3, the sides of which form tracks to which the paperclamp is shown as applied, the platen and base-frame being shown as simply resting on the table and no machine proper being shown in said figure.

Referring now to Figs. 2 to 6, inclusive, the construction of the paper-clamp and the manner of mounting the same on the base-frame will be described. The clamp comprises two main parts-namely, a supporting memberei and a clamping member 5. The supporting member 4 consists of a back bar 6, at the ends of which are arranged transverse guidepieces 7, which are provided with longitudinal ribs or tongues 8 on their inner faces, while between the ends of the bar there are screwed or otherwise fastened preferably three forwardly-projecting arms 9. A clampjaw frame 10 is hinged to the said forwardlyprojecting arms 9 on the supporting member. This clamp-jaw frame 10 preferably comprises a plate with the superfluous portions of the stock of the same removed for lightness and which is provided at its rear edge with an upwardly and rearwardly bent portion l1,the rearwardly-extending top of which forms a flange or abutment 12, for the purpose to be hereinafter stated. That part of the bent-up portion of the clamp-jaw frame which is at an angle to the body of the said frame is recessed at 13, and the adjacent portion of the main body of the clamp-jawframe is correspondingly recessed at 14,so that openings in the clamp-jaw frame are provided, which correspond with and receive the forwardlyprojecting arms 9 on the supporting member. The arms are preferably drilled at their outer ends, so as to receive short pivotshafts 15, which are secured to the clamp-jaw frame 10 by suitable straps 16, secured by screws or other suitable fastenings. By this manner of constructing the clamping member and mounting it on the supporting member the flange or abutment 12 thereon will be located above the back bar 6. At the front edge of the clamping member is a lip 17, which preferably corresponds in width relatively to the width of the base-frame with the width of the largest sheet that may be clamped at its upper edge. This lip is formed of a very thin plate of sheet metal, preferably German silver, which is secured by rivets or in any other suitable manner to the edge of the clamping member, and being quite flexible and yielding it enables the front edge or clamping part of the clamp to conform with irregular surfaces and to clamp a sheet snugly across the portion to be clamped. Located between the back bar 6 of the supporting member and the said flange or abutment 12 of the clamping member is a spring 18, formed of a strip of spring metal, which is secured at about its mid-length by means of a screw or suitable fastening 19 to the midlength of the said back bar, while its outer ends are curved or bent upwardly toward said flange or abutment, with its free extremities bearing upon the under side of the ends of the flange or abutment, so that the tendency of this spring is to raise the flange or abutment and to lower the front edge of the clamping member, causing aclamping action. Recesses or notches 20 are formed in the ends of the flange or abutment 12 of the clamping member, which recesses receive buttons 21, located on the free ends of short arms 22, pivoted at 23 to the hack bar 6 adjacent its ends, said pivoted arms, with their buttons 21, forming crank-like keepers,which may engage the notched or recessed portions of the said flange to lock the clamping member in raised position and to hold the spring compressed for the purpose to be stated.

In the outer edges of the base-frame 3 are preferably formed grooves 24, which receive the tongues 8 on the guide-pieces of the supporting member 4, so that, if desired, the said guide-pieces may be guided on the same and the clamp adjusted along the length of the platen and be removed entirely from the base-frame or readily applied thereto, thus making the clamp an attachment for the machine. When in position, the back bar will extend transversely of the base frame, as shown in Fig. 1 and also in Fig. 2, while the clamping member will be located in front of the back bar and under the carriage, as shown in Fig. 7, and, as shown in the last-named figure, as well as in Figs. 8 and 9, the back bar extends across the rear of the carriage, and thus limits the rearward movement thereof on the tracks. This isaconvenieuce in that when the paper-clamp is adjusted to any point along the platen it serves as a stop to arrest the rearward movement of the carriage at the proper point to bring the printingpoint of the writing mechanism into proper relation with the card or sheet held by the clamp to permit writing thereon without further attention on the part of the operator and dispenses with the necessity of a separate stop requiring independent adjustment. The adjusted position referred to of the clamp may be fixed by means of a clampblock 25, guided on the under side of one end of the back bar, as shown in Fig. 6, which clamp-block receives the pivot23 of the corresponding keeper, said pivot having an eccentric portion 26, journaled in an opening in the said back bar, so that when the said keeper is actuated the clamp-block 25, which forms an opposing jaw to the adjacent guidepiece 7, will be caused to bind upon the side bar of the base-frame.

The clamp described is shown in connection with the machine covered by my application above referred to; but it is of course not necessarily used in connection therewith. It will, however, he described in such connec- H- m .wsautw tion. In that application the carriage 1 has I a plurality of position snamely, a writing position, in which a movable scale 27 and a pointer 28 rest upon the-sheet or leafwhich is being written upon, as shown in Fig. 7, and two raised positions. In'the first raised position of the carriage for enabling a view of the type-written matter for the purpose of correction or otherwise the scale and pointer still rest upon the type-written matter, as shown in Fig. 8. When, however, the car riage is moved to'its second raised position, as indicated in Fig. 9, the scale and pointer are automatically raised from the type-written matter and the sheet or leaf may be removed and a new one inserted. In Fig. 7 the clamping member 5 is shown as released from the keepers 21 22, so that the clamping-lip 17 thereof may be clamped upon the paper or leaf. The clamping'attachment, if adjustable, is ordinarily adjusted along the baseframe, according tothe length ofthe sheet or leaf. The clamp when first placed on the machine has its clamping member in raised position, (shown in full lines in Figs. 2 and 3,) secured by the engagement of the keepers with the flange or abutment 12. Normally after the clamp has been fixed in position by disengaging the keeper controlling the lock 25 from the flange or abutment 12 the clamp-' ing member is in the dotted-line position shown in Fig. 3. The other keeper is, however, first released if a second keeper be used.

When a sheet of paper vor a leaf is to be clamped,the clamping member is raised, the sheet inserted under the clamping-lip 17, and the spring 18 then permitted to act to automatically lower the clamping-lip to the position shown in dotted lines in Fig. 3 and to bind or clamp the sheet or leaf between the lip and the platen. The resiliency or flexibility of the thin lip 17 will permit it to conform to any inequalities in the platen or pa per and to hold the sheet snugly and smoothly. When the carriage is moved to the first raised position for the purpose of exposing the sheet with its type-written matter, the scale and pointer remain upon the sheet while the sheet remains clamped, as shown in Fig. 8; but when the carriage is lifted to its second raised position, as shown in Fig. 9,

the scale and pointer are automatically raised from the sheet, and an actuating-piece 29 on i the carriage strikes the flange or abutment 12 of the clamping member and automatically raises the latter, thereby releasing the sheet or leaf from the clamping-lip, so that the sheet or leaf may be removed and another inserted. This movement (shown in Fig. 9) is ordinarily accomplished when the carriage has been moved back as far as possible upon the base-frame and lifted so that its actuating-piece will strike the flange or abutment, usually after the type-written matter has been printed on the sheet or leaf.
