7 j i a I swmemo E v I W Ae7Zf/7 kyCrdffg swung upwardly, as shownin dot-tedlines in Fig. 3. The supporting element or strip 37 is provided upon its longitudinal edge with a tongue 39, for a purpose to-be de scribed.

The numeral 40 designates a swinging base of a sewing machine, which is hinged to the inner top section 11, as shown at 41. This base 40 is capable of being swung above the inner'top-sect-ion 6 so that the supporting element or strip 37 may be swung upwardly out of the path of travel of the base 40 when'it is desired-to lower the sewing machine to its concealed position. The base 40 is provided upon one longitudinal edge with a tongue 42, for engagement with the tongue 39. Rigidly mounted upon the base 40 is an overhanging bracket-arm '43 of the sewing machine. This sewing machine may be of any well known or preferred type and comprises agrooved wheel 44,

engaged by a belt 45.

The numeral 46 designates a preferably curved shield, which is pivotally connected with a fixed strip 47, to swing in a vertical plane, by means of hinges 48, equipped with spring means, whereby the shield 46 will automatically move to its elevated position when the sewing machine is raised. The shield 46 is disposed below the inner topseotion 11 and forwardly of the sewing machine when the same is in its lowered position, as clearly shown in Fig. 3. R-igidly connected with the horizontal partition'29 of the pedestal or frame 2 by means of bolts 49 or the like are spaced depending preferably substantially U-shaped brackets 50 provided with apertures at their lower ends for rotatably receiving a crank-shaft 51. Rigidlymounted upon this crank-shaft is a large driving wheel 52, provided upon its .perl hery with the ordinary groove for receivl ng the belt 45. The partition 30 has an opening 53 formed therethrough for receiving the depending brackets and the wheel 52 and the belt 45 operates through suitable openings formed the partition 29 and the base 40. 'Thecrank-shaft 51 extends outwardly beyond the frame or pedesattached to the legs 4 in any suitable way,

but 1 preferablyprovide tubular sleeves 58, for receiving the ends of the rods 56. These tubular sleeves carry heads 59, connected with the legs by means of screws or the like. The numeral 60 designates swingingleaves,

which are pivotally mounted upon the horizontal rods 56 by hinge leaves 61, as shown. When. t e lea v s 60 are swung'to their upper vertical position, they engage the lower ends of the walls 6 and form in eifect a continuaingthe shaft .63. The upper block, 65 is normally held in its closed position by a spring latch 68,-which is attached to the block 65, as shown at 69, and carries a tongue 70, which is adapted to engage below the block 64. It is thus seen that by proper manipulation of the latches 68 the blocks 65 may be swung to their open positions and the rock-shaft 63 readily removed from between the. sleeves 60. The rockshaft 60 carries-a treadle 71, which is provided at one corner with a pin 72. The treadle 71 is connected with the crankshaft 51 by a pitman 73 carrying at its opposite ends heads 74. hlach of these heads is formed-of blocks 75 and .76, pivotally connected at corresponding ends by hinges 77. At each end of the pitman 73 there is formed a reduced screw-threaded portion, 78 enin the, block 75. An opening 79 is formed through each of the heads 74 for rotatably receiving the

pins

55 and 72. The block 76 is normallyheld in its closed position by a spring latch 80, connected therewith by screws 81 and provided near its lower end with a tongue 82, which engage below the block. 7 5. Itis thus seen that the blocks 76 may he readily moved to their open positions to permit of the removal of the pitman 73.

When the different elements are in their operative positions the operator moves the treadle 71 with the feet in the ordinary way and accordingly drives the sewing machine.

Whenit is desired to use the cabinet as a desk, the base40 is swung upwardly so that the supporting strip 37 may be swung upwardly to lower the sewing machine and its base 40 to its concealed position. The guard 46 is engaged by the sewing machine and swung downwardly. The supporting strip '37 returns ,to its normal position when released, subsequentlyto which the outer topsection 12is swung :to its closed position to overlap the top-section 11. The pitman 73 is disconnected. from the crank shaft 51' and the treadle 71 by opening'the block 76. The blocks 65 of the stationary bearings 62 are now moved to their open position so thatithe .gaging in a screw-threaded opening formed treadle' and the rock-shaft 63 "may be removed from within the opening 9. The pitman 73 andtreadle 71 may be advantageouslystored within the space 18 of the pedestal or frame 1 and are completely concealed when the door 22 is closed. The

. leaves 60 are nowvswung upwardly to asprising a top and spaced end frames pro vided upon their inner sides with openings,

sume a vertical position in engagement with the walls 6 of which they now form in effect,

a'- continuation. The wheel 52' being disposed within the frame or pedestal 2, is con- -cealed from view. It is obvious that the drawers 33 may be moved to their open position.

It is to be understood that the form of my invention herewith shown and described is to be takenas apreferred example of the same and that certain changes in the shape, size, and. arrangement of parts may be resorted towithout departing from the spirit of the invention or the'scope of the subjoined claims.

Having thus described my invention, I

claim 1. The combination with'a cabinet comswinging leaf-closures adapted to be moved upwardly into said openings, ,5 bearings mounted upon the facesof the leaf-closures which are disposed innermost with respect.

to said frames when said leaf-closures are in their elevated positions whereby said bearings are concealed, a treadle provided with supporting means removably'mounted within the bearings, a sewing machine mounted upon the cabinet, and driving connecting means between the treadlc and sewing machine. a

2. The combination with a cabinet comprising a toplandf'spa'ced end frames provided upon t atreadle dis osed between the en and provide with supportin means, and swinging leaf-closures'adapte to be moved upwardly into said openingsand'provided, upont hefaces thereof which are disposed innermost withirespect to said frames'when .osi;

tions, with holding means to removably ol d* said supporting means whereby such holdthe leaf-closures are in their elevated eir inner sides with o nings,
