wilhaeoozz n HARRY O. SUTTON, OF DENVER, COLORADO.
Application filed February 23, 1916,
To all lwhom t may concern.'
Be it known that l, HARRY 0. SUTTON, a citizen of the United States, residing at Denver, in the county of Denver and State of Colorado, have invented new and useful Improvements in Mattress Sewing Machines, of which the following is a specification. y
rhe object of my present invention is the provision of a simple, inexpensive, easilycontrolled and etcient machine for sewing mattresses.
ith the above object in view, and others which will appear as the nature of the invention is more fully understood, the im.- provement resides in the construction, combination and operative arrangement ofV parts set forth in the following description and pointed out particularly in the appended claims.
The nature of this invention is such that the same is necessarilyv subject to'variations in various details of construction, but a certain and satisfactory embodiment of the improvement is illustrated by the accompanying drawings, in which:
Figure 1 is a perspective view of the improvement, the mattress being arranged thereon in position for the stitching of the edge thereof.
Fig. 2 isa similar view with the mattress removed;A
Fig. 3 is a transverse section taken in a plane at one side of the sewing machine.
Fig. 4 is a side view` of the mattress holder.
Figs. 5 to 8 are details.
Referring now to the drawings in detail, the numerals 1, 1 designate a pair of spaced longitudinally extending tracks which are arranged to be sustained in proper spaced relation upon suitable supports 2.
Arranged for slidablc movement upon the tracks 1 are the wheels 3 of a carriage The carriage has arranged thereon a bed 5 which may be constructed of spaced bars and which has what I will term its rear end elevated by suitable supports secured upon the carriage 4, while the front end of the bed with the front plate 6 is carried by the said carriage 4. The plate 6 provides a stop i member-for the mattress 7 when the said mattress is arranged upon the bed. The upper edge of the front plate 6 is formed with a longitudinally extending iange 8 and this flange is arranged adjacent to and in parallelism with the feed 9 of a suitable sew Specification of Letters Patent.

ing machine l0. Secured to the ends of the front or stop plate 6 are angularly disposed upright slotted bars 11, the said bars having arranged therebetween a pressure strip or bar 12 and secured to the ends of the said pressure bar 12 are straps 13, the same being connected to leversA 14 arranged upon the ends of the carriage. The straps 13 are loosely connected with the pressure bar 12, so that movement of the. levers in one direction will force the pressure bar downwardly in the slotted bars 11 toward the flange or platen 8 upon the front plate 6 of the carriage 4, while movement of the levers in an opposite direction will elevate the said pressure bar, as will be readilyunderstood.
The sewing' machine may be of any desired construction and the cloth plate thereof may be removed, the flange 8, as previously set forth, serving as a platen, and the needle bar as well as the pressure foot .of
low thel front plate 6 is a longitudinally extending rack bar 15, and this bar is engaged by a toothed wheel 16 which is mounted upon a shaft 17.
Upon the shaft 17 of the sewing machine, Figs. 5, 6 and 7, is secured a ratchet wheel 1S). Journaled upon said shaft 17 is an arm having an offset extension 21v which is hollow to receive a spring-pressed dog 21a, arranged to engage the teeth of the ratchet wheel 19. v.livotally connected to the said arm is a pitman 22a which is connected with the needle-operating shaft of the sewing machine, so that the carriage carrying the mattress will be moved and the needle of the sewing machine will be actuated at intervals for the proper stitching of the edge of the mattress. As shown in Figs. 1, 2 and 5, the sewing machine is operated by `power from a motor 5() equipped with a band pulley 51 on which is a belt 52 that is also mounted on a wheel 53 carried by a shaft 54, disposed in vstandards 55. rlhe shaft 54 4is also equipped with a circumferentially grooved wheel 56 on which is a belt 67 that is trained around a wheel 58 on a shaft 59 disposed parallel to the shaft 17. On the said shaft 59 is a grooved wheel 60 that receives a belt 61, trained also around the grooved wheel 62 on the needle-operating shaft of the machine 10. The wheels 58 and 60 constitute two members of a common type of friction clutch controlled by the treadle 18 and link 22,'whereby the operator is enabled to start` and stop the operation ofthe sewing machine and the feed of the mattress. Y
longitudinally step by step so as lto formV an edge on the matttress.
Having thus described my invention, I claim:
l. In a mattress sewing machine, a track, a carriage upon the track, an angularly disposed bed upon the carriage to receive the i mattress, a platen plate upon the bed, slotted upright bars upon the front corners of the bed, a pressure bar received v1n the said slotted bars, link members connected with the pressure bar, yactuating levers for the link members, a sewing` machine having its needle disposed opposite the platen, means for actuating said machine, and'means operated by said machine formoving the carriage step'by step upon'the track.
2. In a mattress sewing machine, a track, a wheeled carriage engaging said track, an inclined bed upon the carriage, a platen upon the forward face ofthe bed, a pressure v bar movable up and down at the forward portion of the carriage, means for so mov ing the pressure bar, a rack bar upon the carriage, a sewing machine having its needle vdisposed opposite the platen, actuating means therefor, a shaft, a toothed wheel upon the shaft engaging with the rack bar, and means, comprising mechanism, arranged upon said shaft and actuated by the sewing machine for imparting an intermittent rotary movement to the shaft whereby to advance the carriage step by step.
3. In a device for the purpose-set forth, a track, a wheeled carriage upon the track, an inclined bed carried by the carriage and designed to receive a mattress, a platen upon v the forward edge of the bed, a pressure bar over the platen, means for moving the pressure bar toward and away from theplaten, a rack bar upon the carriage, a stitching. machine having' its needle disposed opposite the platen, operating means for said machine, a shaft,a toothed wheel located upon the shaft and meshing with the rack bar, an arm journaled upon the shaft, a ratchet vsecured to lthe shaft, a spring-pressed pawl carried'by said armv and engaging with the said ratchet, and means connecting the sewing machine and said arm, wherebyto impart an intermitting rotary movement to the shaft to cause the carriage to be moved step by step.
In testimony whereof I afiiX my signature in presence of two witnesses.
