MORRIS G. ROSENTI-IAL, F CINCINNATI, OI -IIO, ASSIGNOB. TO ROSE LABEL MACHINE COMPANY, OFGRAND RAPIDS, MICHIGAN.

; PATCH 0R LABEL STITGI'IING MACHINE.

Application filed September T 0 all whom it may conceive:

Be it known that I, Mourns G. ItosE 'rin L,

a citizen of the United States, residing at for the work holders of such machines and to provide improved guide means for the carrier head which can be adjusted for wear.

Further objects and objects relating to details and economies of construction and operation will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means describedin the following specification. The invention is clearly defined and pointed out in the claim.

A structure which is a preferred embodiment of my invention is fully illustrated in the accompanying drawing, forming a part of this specification, in which:

Fig. I is a detail plan view of a structure embodying the features of my invention.

Fig. II is an inverted detail plan view of the top plate showing the cam plate and the trip lever disposed thereon.

Fig. III is a detail sectional view on line 33 of Fig. V of the actuating means for the trip lever, the trip lever being indicated by dotted lines at the corner of the carrier head.

Fig. IV is an enlarged detail sectional View taken on irregular line 4-4 of Figs. I, II and V.

Fig. V is an enlarged detail sectional view taken on line 55 of Figs. I, II, III, IV, and VI. 7

Fig. VI is a detail elevation view from the lower side of Fig. I, showing the adjustment of the gibs on the carrier head.

Fig. VII is an. inverted plan view of the main inner slide.

In the drawings the sectional views are taken looking in the direction of the little arrows at the ends of the section lines and similar numerals of reference refer to si1nilar parts throughout the several views.

Referring to the numbered parts of the drawing, 1 is the bed of a sewing machine. 2 is the base plate of my improved structure suitably secured to said bed. 3 is the main or inner slide provided on its lower surface with beveled slide ribs 4:, 4. These are engaged by adjustable gibs 5 held in position on the base plate by suitable screws 7 in slots (5, as seen particularly in Fig. I. These gibs are tapered on their back edge at 8 and engage a tapered shoulder 9 on the said base plate 2, whereby when they are adjusted laterally they take up the slack or wear upon the guiding rib 4E.

The carrier head 10 is provided with an arm 11 carrying the work holder 12 which is shown in fragment inFig. I.

{In opposite sides of the carrier head 10 are disposed beveled gibs 13 held adjustably in place thereon by screws let in slots 15 formed longitudinally therein, whereby they can be adjusted to take up the slack.

The inner edges 16 of these gibs 13 fit against the beveled sides 17 of the carrier head 10 whereby they are adjusted to take up wear. The gibs 18 fit upon the opposite beveled bearing surfaces 3, 3 upon the main slide 8, as seen in Fig. V.

Within the carrier head 10 is disposed a rectangular internally geared rack 18 made up of various parts or of an integral structure as circumstances may require. Engaging this rackis a driving pinion 19 which is supported on a driven shaft 20 (see Fig. IV) which is j ournalled at its upper end in the top plate 21.

The top plate 21 is secured in place by suitable screws 21 (see Fig. I). The cam plate 22 is secured to the under side of this top plate 21 (see Figs. II, IV and V) and is provided in this instance with a rectangular cam groove 25 which engages and guides the pin 26 on the carrier head 10. The cam plate 22 is adjustable in assembling by the screws 23 and is retained securely in place by pins 2%, 24 in opposite corners thereof.

27 is the trip lever pivoted on the underside of the top plate at 28 and projects for engagement with the stop lever 31. This trip lever 27 is provided with an actuating pin 29 disposed to be acted upon by pin on the top side of the carrier head (see Figs. I, II and III). I have not shown the details of the connection for the stop lever, as my invention does not pertain to the same, and have only shown enough of the trip lever to make operation of the parts clear so far as my invention is concerned. My invention pertains particularly to the means of actuating the carrier head and retaining the same eifectively in position.

Vith my improvements it will be noted that the guide means are disposed the one transversely to the other. The controlling means is the cam in the top plate engaging with the pin on the carrier head and as a consequence it does not matter which gib is adjusted for taking up the wear and se curing close adjustment, because the pin in the cam slot controls the relation of the parts. They are never thrown out of center or out of proper operative relation to the stitching means at the front of the machine. It is clear that this structure lends itself to the motion of the 'arrier head and arm in any direction in which the same can be propelled by a pinion on a continuous rack. I have shown the same rectangular for the attachment of rectangular patches or labels but the same can of course be made of diflerent shapes. The same can be used for applying stitching without applying a patch or label, which is frequently of advantage for the purpose of reinforcement or of ornamentation. I have shown only the one form, but it is clear that the forms can be varied indefinitely and I do not wish to be restricted to the particular form illustrated.

While I have shown certain parts integral and others made up of various parts adjustably joined and while I have shown them adjustable on both sides, I have done this because it is the best construction that I have thus far been able to develop that admits of complete adjustment with least variation in the general appearance of the device. I do not wish to be restricted in my claim to the specific devices I have shown, which however I consider to be meritorious. and which I desire to cover specifically as well as broadly, as pointed out in the appended claim.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

In a carrier head structure for a label stitching machine, the combination of a base plate adapted to be secured to the bed of the machine, a slide with guide ribs transverse to the bed of the machine, of dovetail form, adjustable gibs on the said base plate for adjustment to the said ribs on the said slide, a carrier head with arm and label holding device disposed above said base plate with its longitudinal sides beveled in opposite directions, guiding gibs adjustable on the said beveled sides of said head with downwardly projecting guide ribs dovetailed to engage the opposite ends of the said slide, a centrally disposed internallygeared rac-l; conformed in size and dimension to the label or work to be done, a pinion disposed on a vertically disposed driven shaft in engagement with the said rack, a to plate extending over the said carrier head, a cam plate disposed and secured on the under side of said top plate, with a cam therein corresponding to the said rack, and a pin on the said carrier head engaging said cam to be guided thereby, all coacting substantially as described for the purpose specified.

In witness whereof, I have hereunto set my hand and seal.
